Frequently Asked QuestionsQuestions our customers have asked about the EV Trip Optimizer for Tesla App.
Where do I optimize the app?
The app will generally optimize after every change automatically. There are two places you manually have to choose to optimize:
- When you create a trip you choose either Manual or Auto for supercharger allocation
- If you want the app to reconsider it’s charger choices – choose Refresh Auto Chargers from the Plan Trip menu
I keep getting a message that no route can be found.
Check the Settings in the main menu and make sure you have selected the appropriate region. While you are there review the units you would like to work in and the default state of charge values. Also check to make sure that your speed adjust and power factor as well as Minimum State of Charge are appropriate in My Cars. These values can also be changed on trip basis too.
How do I create a new route and start over?
When you use the new trip feature (from the main panel, Current Trips or Plan Trip menu) you will create a fresh trip. There is no need to delete waypoints, chargers or origin/destinations.
If you have not subscribed, then the currently active trip will be replaced. If you have subscribed then a new trip will be created and the currently active trip will still be available from the Current Trips menu item.
How is the optimization performed?
The application, along with a set of servers, optimizes your trip through a set of fairly complex algorithms. Included in the models are:
- The characteristics of your car and loading/passengers
- The driving time and distance to all your regions superchargers
- Any additional waypoints you have selected
- The weather en route including temperature, wind speed/direction and precipitation
- Your driving power profile (power factor) and any speed adjustments or caps you have applied
- Estimated charging times
- Elevation gains or losses
- Nominal traffic flow and your estimated speed
- The starting and minimum SoC at waypoints
- Any constraints you have placed on waypoints such as minimum charge, return to last charger, reserved destination travel
- If you have Disliked any potential charging stops
The application actually optimizes in multiple passes. First the routing and superchargers are selected based on stops. Then an optimal route is chosen through the selected waypoints and chargers including traffic impacts. Lastly detailed energy consumption and charging times are determined based on fractions of trip segments using all the available information.
Why does Refresh Auto Chargers not use one of the routes shown at first?
When you first select your destination and optionally an origin, the app shows you the routes Google Maps would take if you were driving an internal combustion engine (ICE) car when you select Manual. Whe you select Refresh Auto Chargers the app decides where to route to based on the fact that you are driving an EV and will need to charge it, so it could be that none of the routes Google picked (based solely on driving time), are appropriate for the given situation.
I can no longer resume my current trip.
EVTO shows one trip at a time in the Plan Trip (map) panel. If you delete or archive the active trip, you will need to set another trip active.
Go to the Current Trips menu item and then select the name of the trip you want to activate. Your selected trip will now become the current or active trip the Plan Trip panel will be loaded next.
Why is there a subscription fee for trip planning?
We have to pay service providers (weather, trip routing, elevations, charger locations) a fee based on usage.
By default the application allows you to plan one trip for no charge up to 300 mi/800 km. You can delete this trip or change it as you wish. We feel that heavier users that plan many trips per month or longer more complex trips, should pay for the services they are consuming.
Do I need two subscriptions if I have both Android and Apple devices?
Unfortunately yes. The subscriptions are purchased through each store and there is no way to provide a credit between them.
Note your trips can be shared between the two devices by using the Share feature in Current Trips.
My calendar entries created by the App do not appear on my Tesla.
My calendar entries created by the App do not appear on my Tesla.
Changes to My Cars or Settings do not update my trips.
How do I change the starting SoC?
What do the colors on the map push pins mean?
There are six colors that can be depicted on the map push pins:
- Green – indicates you should safely make it to this waypoint
- Yellow – indicates you will probably make it to this waypoint within your set minimum SoC
- Red – indicates it’s unlikely you will make it to this waypoint with the current limitations. You will need to review your settings or add additional charger(s) between the last green waypoint and the one that indicates red, and/or Refresh Auto Chargers
- White – A white destination pushpin indicates the trip needs to be recalculated. This rarely displays for more that a few seconds.
- Blue – The origin always has a blue pushpin
- Grey – Chargers that are not waypoints or not needed for routing, but are shown as backups.
Note: The red, green and yellow colors are also utilized on the SoC chart with the same meanings.
What do the battery colors mean?
The batteries on the map Waypoint Inspector popup and the Segment Details panel show the state of charge upon arrival. (Note the origin shows the departure SoC). The colors of the battery image matches the car and mean:
- Green – over 20% SOC should be available on arrival
- Yellow – over 10% and up to 20% SOC available on arrival
- Red – 10% or less SOC should be available on arrival
- Blue – the energy reserved at the destination for local travel
What features are provided in the subscriptions?
Is there a quicker way to get to my current trip?
If you have viewed the Getting Started panels or created a trip, then you should be able to get to your current trip, or plan a new trip if there is no active trip, directly from the large Resume button on the main panel.
To change the active trip you will have to select one of the trips from the Current Trips panel. Note that changing to a different car in My Cars will require you to reselect an active trip.
The charging times seem too short or too long.
There are a lot of influences to how much time it takes to charge the car. The app has many models depending on the charger type and the arrival and departure SOC estimates. In addition at the charger itself the number of users, how they are paired and the weather can all play a role. At best the estimates the app gives are the best case scenario. Your times may often be longer.
Note: The minimum charging time is set to 10 minutes. Even though you may only need a few minutes of charge to reach the desired SOC, the app will never charge for less than 10 minutes. There is also a 5 minute interval set asside for setting up and taking the car down for charging. So each charging stop will be a minumum of 15 minutes in duration, where at least 10 minutes is spent charging.
The app seems to over/under estimating my energy consumption.
First it is important that you have correctly entered your cars values in the My Cars menu item on the main panel and that your travel date and time are correctly entered in the Edit Segment Details panel. If you have done that and your trips are always over or under estimated, you should adjust your Speed Adjust and/or Power Factor.
Adjusting the speed adjust or power factor can be done in the Edit Segment Details menu item from the Plan Trip panel. Note if you change the value here it will only be applied for the current trip segment. A negative number will be more conservative in its consumption estimates while a positive number will be more aggressive.
The power factor and speed adjust only applies to the driving portion of the optimization algorithm and is essentially a driving style adaptation. If you drive very conservatively you may need a lower power factor setting while if you drive more aggressively, and use the brakes rather than regen braking, you will need a higher setting. The speed adjust is added to the speeds that Google estimates, about 30 mph.
What determines the energy needs at waypoints and the destination?
The application uses science based estimation in determining your travel needs. This means there is a set of algorithms based on the following:
- Trip distance
- Speed of travel
- Number of stops
- Driving style
- Weather – temperature, wind speed and direction, precipitation
- Road conditions
- Weight of car and passengers (payload)
- Car type and features
- Elevation changes
- Cabin temperature
- Climate control setting
In addition you can reserve additional energy at a destination for local travel.
How do I force the planner to use a certain route?
When you plan a trip you enter your destination. The application starts the trip at you current location unless you have also provided an origin. You can change the origin by editing it from the map pushpin. When you Refresh Auto Chargers, the application will chose the best route based on the optimization model chosen in Settings and conditions forecasted.
If you do not like the routing chosen for you, just add a waypoint (either pressing on the map or using the Add Waypoint menu item) anywhere along the route you desire. If needed you can repeat this process to further refine your desired routing. Be sure to Refresh Auto Chargers after you have settled on all our your added waypoints.
One of the biggest influences to your routing will be charging stops. The application will immediately let you know if you can safely reach the next charger to test your ideas. Try different chargers to influence the route and/or overall trips times. Refer to the Consumption and SoC charts to see how your energy is consumed en route.
Note: If you Dislike a supercharger, it will receive a time penalty and the application will attempt not to use that charger if there are other alternatives. This could dramatically change the routing for a given trip.
What is being optimized?
Can I increase the arrival SoC for one or more waypoints on my trip?
Yes. Go to the waypoint pushpin and select the Edit icon. Change the Minimum SOC for that waypoint. This will force the upstream charger to attempt to satisfy this demand.
Note: If you want to change the minimum SoC for a automatic charger, you will have to make it required first. You do that by the waypoint Require button.
What if I want to stop at a waypoint for a longer time?
You can stop at waypoints that are not for charging or when you want to stop for longer than the charging needs indicate. Choose the Edit icon from the waypoint inspector and then change the Minimum Stop Time slider.
Note: You can only change these attributes on automatically selected chargers after you make the charger required.
How do I change a waypoint address or location?
How do I complete a trip?
What do the symbols mean on the charger icons?
Each charger icon (pushpin) has a symbol embedded in it to let you know the type of charger it is. The symbols are the following:
- S Tesla Supercharger
- H Tesla HPWC
- – Level 1 charger
- = Level 2 charger
- ≡ Level 3 charger
- J J1772 charger
- M CHAdeMO charger
- E CEE charger
- R Tesla Roadster chargers
- C CCS chargers
Note: Before chargers are waypoints, they are shown in grey to let you know they are not part of the trip. Automatically selected chargers are shown with a small A contained within a red circle.
How can I change the origin?
By default the origin is either at your current location or is the destination from a continuation or return trip.
If you want to plan a trip independent of your actual location, just enter your origin in the first box. If you later want to update the origin select the Origin pushpin and then select Edit. Now you can change the address and the program will automatically recalculate your route. You may need to select Refresh Auto Chargers for the trip segment if the new location is not close to the current location.
Note: If you have Location turned off in the settings, you will have to manually enter your origin for each trip.
How can I reorder the waypoints?
Generally you should not have to reorder the waypoints as they are picked with the route for the most optimal trip. However there are conditions that may require changing the order of one or more waypoints.
Sometimes you may wish to force the waypoint order. If that is the case you may move any of the waypoints using the ∧ and ∨ buttons on the right of the waypoint in the Segment Browser popup. When you have reordered the list just select the Calculate New Routing button. If you wish to restore auto ordering of waypoints then select the Restore Auto Waypoint Order button.
Note: After you Refresh Auto Chargers for a trip, you may need to readjust any waypoints you manually moved out of order.
It's hard to visualize the table on the Trip Details.
How can I reserve extra energy at the destination for local travel?
This feature is contained in the Edit Segment Details popup panel in the Plan Trip menu.
You enter your required reserve in distance based on your settings (mi or km).
Where is my trip data stored?
All trip data is stored on the mobile device. During Refresh Auto Chargers the list of your chosen waypoints is sent to a server to be used for routing. No personal or car identification information is included and the data is not stored or used beyond the few seconds the optimization takes place.
Note: If you share a trip then the trip data is stored on a server for 30 days, but no association to a car or user is kept on the server.
What do the two flat lines represent on the Consumption chart?
The solid line represents your cars advertised consumption average (rated consumption). The dashed line represents the active trips average energy consumption. You can tap on either line to see the value and label.
The consumption chart depicts your estimated average energy consumption for each driving leg. This can vary dramatically depending on terrain, weather and driving style.
How do I see my entire trip on the map?
Press the globe icon on the upper right corner of the map.
Whenever you make waypoint changes the current zoom is saved in case you want to further edit that location on the map. It will be reset to the entire trip if you return to the main panel.
Note: On Android devices you may use the small icon in the upper right corner of the map to make the map fill the entire device.
Note: On continuation (multi-segment or return) trips, only the active segment is zoomed when you press the Globe icon. You can see the entire trip by pressing and holding on the globe icon.
How can I include my own destination or waypoint chargers?
How can I indicate which supercharger I want to use?
There are three ways to manually include superchargers into your route:
- Make an automatically selected Supercharger required.
- Select the supercharger from the map
- Entering the supercharger name after selecting Superchargers from the Charger Filter pull down on the Add Waypoint popup panel
How often is the weather forecast updated?
Why are there spikes on the Consumption chart?
What is the purpose of archiving trips?
Can I access the raw trip data?
Raw trip data is embedded in the app and is not user consumable. However if you have a subscription you can get a Comma Separated Variable (CSV) version of all the energy and travel data for each leg of the trip to be used in other programs like spreadsheets.
To access this data go to Segment Details and select Export Data.
When will the Model 3 be supported?
Can I join your beta team?
Why don't you get the SoC data directly from the car?
Currently we are not interfacing directly with the car and have no immediate plans to do so. Tesla does not provide a secure and reliable way to obtain data in a published manner. We value your privacy and are not willing to take on the responsibility of being a potential security leak to your privacy or safety.
Truth be told there is very little value we can obtain from accessing the data in your car. Our algorithms are science based and do not use statistics or deep data mining to try to guess the best possible solution like many other offerings do.
Why is the address disabled so I can't edit it?
How do I add a waypoint to my favorites?
You can easily add any waypoint as a favorite which you can use when creating trips or adding waypoints. After the waypoint has been added select the pushpin on the map and when the popup window appears, you will notice a small heart at the top of the panel. Just select the heart (it will turn blue) to save that waypoint in your favorites or deselect it (it will turn clear) to remove it from your favorites.
To use the favorites just select the heart next to the address or place name on the New Trip or Edit/New Waypoint popup panels. A list of your favorites will appear.
Note: You can edit these favorites from the main menu, Maintain Favorites, menu item.
Why does the app use percent vs rated miles/km for SoC?
How can I indicate I am using the rear climate control for split system cars?
How do new superchargers get added to the app?
We attmpt to update the supercharger lists every week. The application will automatically download any new superchargers at application startup. If you need to add a new supercharger before that, use the Add Waypoint feature and indicate it as a Tesla Supercharger.
If you are aware of a supercharger that is listed on Tesla’s webite that is active but not in EVTO, please send us an email.
Can I change the chart types or colors?
Why are there multiple colors on my battery icon?
The battery represents the SOC that you will have when you arrive at that waypoint (the origin battery represents the SoC at the start of the trip). Since you can arrive at a waypoint more than once (Return to last charger feature) or retain a certain amount of energy at a destination for local travel, we show both levels on the battery. Charging waypoints also show you the estimated departure charge amount in diagonal gold stripes.
Note: Also indicated below the battery is the numeric SoC for both visits. The first visit SoC is on the left.
Note: Energy reserved for local travel is shown on the battery in blue.
Can I enter a supercharger name versus choosing one from the map?
To add a new supercharger by name versus selecting from the map select the Add Waypoint menu item. When the popup panel appears change the Charger Filter to Tesla Superchargers. Now you can enter the name of the supercharger in the Place Name field. It will find matching superchargers as you type so you don’t have to enter more than the first few characters.
You can also do this for Tesla destination chargers too using the same procedure.
What is a continuation trip?
A continuation trip is a trip with multiple segments. An example would be a trip you took over many days (each day being a trip segment). The first segments destination becomes the next segments origin and so on until you return back to the original origin.
Note: If you change a origin or destination waypoint that is paired with another trip segment, both waypoints will be updated and both segments will be recalculated automatically.
The trip is handled as one large trip and you can easily move from segment to segment from the Trip Browser popup on the map. Use the little map icon on the right center of the map. The total trip stats are also included in the popup panel.
How can I divide a trip into segments?
Why do you need trip segments?
- On smaller devices the Segment Summary waypoint list could get quite large and unusable
- If your routes overlays each other (like first driving from Seattle to Portland and then making a loop trip before going back to Portland and Seattle – a Q shaped trp), you could not tell which route was inbound or outbound on the tail of the Q and you would not know which waypoints went to which part of the trip on the map
- If the total multi-segment trip was shown on small devices, you could not see the details for your current days journey without constantly re-zooming/panning
- Each segment can have a different start date/time and therefore a more accurate depiction on the trip, better weather forecasting and it correctly depicts in your calendar for use in the cars navigation system.
- You are not required to use the multi-segment feature. You can plan your just trip as one unit if you wish. Just enter a waypoint for each logical segment endpoint.
- The total number of waypoints for the trip exceeds Google’s maximum of 23.
How do you handle older cars whose battery has degraded?
How do I determine the battery life % of my car?
When your car was first manufactured it had a maximum range. Over time the battery will degrade and you will obtain less and less range than what the car was when new. This will affect the accuracy of the calculation the that EVTO application makes in its trip optimization. To correct this we have allowed you to indicate what the battery life is of your car, contained in the Battery Life in the My Cars panel.
To determine your current battery life percent:
- Switch your cars display from percent to rated range
- Charger your car to 90%
- Note the rated range available and enter it in My Cars
For example: A brand new Model X 90D with 20″ wheels had an advertised EPA range of 257 miles. 90% of that maximum range is 231 miles. Your car, at 90% charge, is showing 215 rated miles.
Can I share my trips with others?
You can share your trips with other EVTO users from the Current Trips panel. Use the Share Trip to select a trip to be shared. The application will prompt you for a unique four PIN and create an email for you to send to your recipient(s).
To receive a shared trip you will need the unique Trip ID and PIN as sent in the email and use the Import Trip menu item. Just copy the ID and PIN from the email into the popup panel.
Note: If you import a trip without a subscription, it will replace your currently active trip. You will be prompted before the application carries out this action in case you want to cancel the request.
How do I compensate for towing a trailer?
How can I avoid superchargers I don't like to stop at?
Select a supercharger pushpin (one that is not an automatically selected charger or not part of your trip). Then select the Thumbs Down icon which will turn red. This will force additional time on this supercharger during optimization and if possible, will cause it not to be used in future trips or routing.
You can deselect the Thumbs Down icon if you later wish to remove the dislike, or use the Maintain Favorites item from the main menu.
Will you be providing non Tesla chargers for locations outside of the USA?
We are currently evaluating adding the ability to see non Tesla chargers at a given place on the map for locations not based in the USA. There is no estimated time for this feature. You can use the app along with PlugShare. Simply go to PlugShare and select the charger you wish to use in EVTO. Then use the Share feature of PlugShare to capture the charger information. Return to EVTO and use the Add Waypoint dialog. Paste the data copied from PlugShare into the address field and it will set the charger type and address appropriately. You may need to adjust the charging rate as required.
Today you can add any type of charger you would like manually. Just use the Add Waypoint feature on the Plan menu. You can also make this a Favorite to be used over and over again.
What happens to my trips if I migrate to a new device?
If you anticipate migrating to a new device you should Share any trips you want to save to yourself. Then when you receive the new device and install the EVTO application, you can then import the shared trips.
Note that any In App Purchases (IAP) you have made are with your account and not the device. So when you get your device and install the EVTO application, just use the Restore Purchases menu item.
What times are displayed for arrival and departure?
What happens to my saved trips if I don't renew my subscription?
If you had a subscription and saved trips and then decide not to renew the subscription, your trips will be saved and you can renew or use them.
However you will only be able to replace the active trip when you create a new trip. You will not be allowed to add to your trips unless you renew your subscription.
Where do I adjust the speed?
You add this in the My Cars feature for the default for each car. Then when you create a new trip this will become the value for the trip and any new trip segments.
If you later want to change the speed adjust for a trip or trip segment, you will do this via the Edit Segment Details panel.
Where do I change the global setting for payload, power factor and the cabin temperature?
You set these in My Cars. This will then become the default for any new trips. Each trip retains these settings so you will need to change them on a trip basis in either Edit Trip Details or Edit Segment Details panels.

Tips for Winter driving and use of EVTO
- Do not start your trip with a cold battery. Plan on charging for at least an hour before your first leg. If your battery is cold then the car will have to use some of it’s power to heat the battery and unfortunately EVTO cannot predict this so the range will be off on the first leg.
- Set Range Mode on in your cars setting to use as little battery heat as you can.
- Slow down and don’t go over the speed limit in legs you have a concern about. Speed is just like a head wind. It will use more energy.
- Monitor your real time usage in the car and perhaps limit cabin heating as much as possible until you feel you are going to safely make it. Supplement with the seat heaters which are more efficient than heating the entire cabin. Note the car calculates the remaining energy based on what it recently used so it’s not absolutely correct unless the rest of the trip matches what you have recently driven. Also note that the early parts of the trip may consume more energy based on the heating points above.
- In Edit Segment Details there is a setting labeled Minimum SoC. This will be the minimum target for any supercharger you visit. By default it is set to 15% in Settings, but you can change it individually for each trip segment in Edit Segment Details.
- For the destination and any manual stops you will find a slider that will increase the Minimum Arrival SoC in the Edit Waypoint dialog.
- You can also increase a setting called a Power Factor in Edit Segment Details. This will increase the consumption of the car more than normal. Try 5 at first.
- In the same dialog there is a slider called Speed Adjust. Increasing this will cause EVTO to estimate more energy consumption for that segment. But again I would not drive faster during these critical segments. You will just make matters worse.
