    When you click on the charger you get this : Showing that the source of the charger is NREL.gov. The link takes you here, where you can provide them with the correct information: https://developer.nrel.gov/contact/

    Thanks for contributing your data to ABRP! We've added setup instruction to a page within the planner itself to simplify the setup process. To set up live data for your car, navigate the ABRP Planner and select "Show Settings > Show More Settings > View Live Data > Setup" Currently, the following vehicles are supported with OBD setup instructions: Chevy Bolt Hyundai Ioniq Hyundai Kona Kia Niro Kia Soul Nissan Leaf And we are happy to add more once it's possible to retrieve data via an OBD adapter! Please let us know if you've managed to pull data from your car, we'd be happy to work with you to add it to ABRP.

    Currently options codes as returned by the Tesla JSON API are unreliable and affects all API users, such as ABRP or TeslaFi for example. You can still manually override after wrong option codes were parsed.

    Introduction One of the questions we get fairly regularly at ABRP is if and when we will support other Electric Vehicles in the planner. To create a model the planner can use we need two aspects defined: Driving Consumption and Charging. Once we have a model for a car, we have three markers we’ll put in the planner: Alpha – An initial model based on measurements or data by external parties, not thoroughly verified. Beta – A more mature model validated by matching to owners’ actual road trip numbers Release – Model verified and improved by recorded real life driving data. Once you have the data we need to make Driving Consumption and Charging Models, email it to the ABRP Team, and we’ll work with you to get the model on the site. We won’t make any car model available on ABRP without first verifying accuracy with an actual owner of a car, so it helps immensely if you’ve got an example road trip you can recreate in the planner once we’ve prepared the model. Emails: bo@abetterrouteplanner.com jason@abetterrouteplanner.com Driving Consumption Model The driving model is the most important part of the planner, as it calculates how much battery you’ll use on each leg of the trip. To do this calculation, the planner uses a third order polynomial to calculate consumption. This is based on the physics of driving. There are several ways to create this driving model, listed here in order of accuracy: 1 – Analytical Physics Model Creating an analytical model requires the least access to a car, but it’s the least guaranteed to be accurate. To create an analytical model, we use the physics of driving: Pdrag = η*Cd*A*v3 Prolling resistance = η*Crr*M*g*v Pidle = Constant Combining these three terms, we get a full equation for the consumption of a given car. We then multiply by the drivetrain efficiency, what percent of battery energy goes into creating motion. To create this model, we need to fill in a few variables: Parameter Description Cd Coefficient of Drag - Typically available online, but takes a little bit of research to verify. A Frontal Area - Cross-sectional area of the vehicle. This can be calculated roughly from front or rear photos of the vehicle and the vehicle's dimensions Crr Coefficient of Rolling Resistance - Mainly based on the tires, and drivetrain of the vehicle. A little harder to dig up. This typically varies from about 0.007 for very efficient tires to 0.014 for wide performance tires. M Mass - Curb mass of the vehicle. Pidle Idle Power - The amount of power drawn by the vehicle when sitting still. Best drawn by looking at the built-in energy meter while at a stop. Typically around 1-1.5kW η Drivetrain Efficiency - Efficiency of turning battery power into movement. Generally between 85%-95% If you can provide all of these parameters, we can create a model that is fairly accurate. 2 – Manually Collected Driving Data The next-best method is calculating the driving model from approximate real-world data. This can be gathered by recording consumption while driving. By observing the power draw at various speeds on flat ground, and providing data points we can calculate a better consumption model. In general, we need the highest number of data points at freeway speeds, as you tend to spend most of your driving on a trip at those speeds. I would recommend noting the power consumption readout at the following speeds (km/h and mph are not exactly equivalent, for ease of use, please note which unit you used to collect data so our model can be as accurate as possible). If you plan to use this method, be sure to drive safely, you may want to recruit an assistant to take the power draw notes while you drive. Speed (km/h) Speed (mph) Power (kW) 30 20 45 30 60 40 75 50 90 55 100 60 110 65 120 70 130 75 140 80 150 85 3 – Collecting Driving Data Directly This is the best way to build an accurate model. This can vary by vehicle or manufacturer, but most vehicles provide data via the OBD port. For an example, see the for the generic OBD and Torque instructions. To contribute data this way, set yourself up with Torque Pro, and find a PID list for your car. If you can find these things, and can verify the data shown on the Realtime Information display in Torque is accurate, contact me (jason@abetterrouteplanner.com) to set up the server to receive your data. Once there’s enough data for your vehicle, we’ll perform the same analysis we’ve done for all the currently released models in the planner. Charging Model The charging model is a little easier to build from available information. If you can find a plot of the maximum charging speed relative to State of Charge, or a video that shows power in kW and battery %, we can build a charging model from that. Something like the following chart (sourced from Fastned for the Hyundai Ioniq): Fastned charging data for the Hyundai Ioniq Again, however, the best way to build a charging model is to contribute OBD data directly from a charging session. See the setup instructions in the previous section for what’s needed to submit OBD data.

    Definitely something we can think about, though not a capability yet. The question is how best to implement such a feature, perhaps once charging has stopped at a given waypoint push the next destination? I'd expect something like a checkbox "Auto-push to Tesla" or similar.

    I've just started using ABRP as an in-car tool rather than just a planning app, and I'm finding it rather difficult to use. I'm wondering if we can have a discussion about improving it. I expect some of this comes from the difference of using it on a large built-in interface (e.g. Tesla) vs a phone or tablet, so maybe these features want to be optional or selected on the user-agent string? Generally I'm finding the interface too busy and cluttered, and I need to be too precise to use it in a moving car. It takes too much attention away from the road, so I wanted to feedback what I think could be done to simplify things and make it safer to use. All of the changes I'm talking about are in reference to driving. I'm not seeing a need to change things for planning. A realise that might mean defining a "driving GUI" which doesn't really exist yet, as what we have is a small modification on the planning results page. I should preface this with saying I'm using Firefox on Android. Maybe some of these are Firefox-isms. Full screen - Screen real estate is at a premium, yet I've got the address bar locked at the top. It's not going to disappear because that only happens when you scroll down a page which doesn't apply here. I've seen some web-apps go full screen. Could ABRP do this when on the move? Map scale - The default scale seems to be to show the whole trip. This is useful when planning, but isn't very useful when driving as you can't see detail when approaching a charging stop. Could we auto-scale to show the car and the next charging stop? Then as you approach a stop you're getting more and more detailed information about how to find it. The Itinerary aka the top drawer - I personally don't think this needs to be available after planning, but certainly should auto-hide once moving. Buttons - I think it would be good to reassess which buttons are needed and when. I'm finding certain buttons are in the way and some I have to go digging for. The '?' button - It needs to die, at least whilst we're on the move. On a smaller screen it just takes over the whole display, and has lots of hot links which will take you off round the web as you're trying to get rid of it. Zoom buttons - I'm finding pinch to zoom is awful on the web app because it doesn't work if you hit a UI element by accident (e.g. the charger information bubbles). Couple this with trying to do it whilst keeping your eyes on the road, generally because you're approaching the area where you need to find a charger and so need to change lanes to come off the motorway or something. Generally auto-zooming would get rid of most of the need, but a quick tap to zoom in/out would generally be easier. So can we move them out of the dock during driving? Back arrow - Returning to the planner is a pretty devastating thing to hit by accident whilst driving. Can we make this less prominent? Battery adjustment - I like the functionality, but invariably when I'm trying to nudge the battery level up or down I end up selecting the value text in-between the two buttons and getting caught up in cut and paste menus. Is there something that can be done to make all text unselect-able? Maybe make the hot spot for each button overlap onto the text? Night mode - Can we automate it based on local time? User preference if you like. Then lose the button. Centre on car - Make it a "return to default view" button which appears only when user isn't on the default view? Slow charger filter - Only useful for planning? Hide whilst driving. These changes would mean that we're left with only the two zoom buttons most of the time, and a return to default view some of the time. No expandable dock necessary. All of these are my opinions only, so please understand this is all said in a spirit of making ABRP a better tool. I realise there may be good arguments against any of them (including developer time). Thoughts? Alternative suggestions? Developer feedback?

    Sorry for the delay on the mobile app development. I was bothered with my other stuffs this month. I talked with the Bo earlier in July and started development in August. I would say the progress for now (actually I didn't have time working on any of it this month tho) for now is 80% done. I will resume the app development and polish next week and hopefully I would have a preview for you by the end of this month.

    (Edit 2019-08-16: Added Model 3 SR+) (Edit 2019-09-06: Added BT70) Since we last wrote about Tesla supercharging, Tesla vehicles have received quite a few software updates (as usual). Some seem to have modified the charge curves of some car models, and especially the classic Model S 85 owners have been noticing some relatively big decreases in charging power. As usual, we at ABRP have actual data thanks to our generous users who contribute it by logging in with their MyTesla account in ABRP and checking "Share data" (and even "36h Background sharing") for us. This is all thanks to you! So, without further ado, let's dive into plots. BT85, the classic Model S85(D) 85 kWh battery The plot below shows charging data for BT85 from May 2019 through August 2019. The blue dots shows all samples collected by ABRP during supercharging for those vehicles, and the red curve shows the ABRP charging model for S85 based on data up to May 2019. As you can see, it still seems to model good charging performance pretty well. However, somewhere in June, the charging speed was changed after a SW update. The new charging data, now only from July-August is substantially different: The red curve is the same as above, and the additional green curve now models the new behavior based on the new data. Obviously, the charging power drops much earlier at lower SoC (battery %), which leads to a slower typical charge sessions. Our standard charging benchmark from 10 kWh to 50 kWh has changed from 29 minutes (May) to 34 minutes (August) for the BT37. No disaster, but also not so fun for S85 owners. BTX6, Model S/X 100D 100 kWh battery When we last updated the BTX6 battery model, after the spring Supercharging power increase, we noted that while peak power was indeed increased to 140 kW, it usually quickly dropped down to 120 kW, probably due to thermal issues. Now, while most data is from Superchargers with only 120 kW capacity, there are quite a few sessions where charging power is sustained at 140 kW. Good news for 100D owners! BTX4, Model S/X 90D 90 kWh battery The not-so-fantastic "90" kWh battery (actually 82) has also been slightly modified, with most sessions seemingly limited to 120 kW. We have updated the ABRP model accordingly. Note that there seems to be a collection of sessions which peak at about 94 kW, this may be the infamous charging power limited vehicles which have Supercharged "too much". BTX5, Model S/X 75D 75 kWh battery Only minor changes can be seen in the charging curve for the BTX5 battery and we have updated ABRP accordingly. BT37, Model 3 Long Range battery The fast-charging Model 3 Long Range battery does thankfully not seem to have changed at all! The curves show the fast 190 kW charging for users at Ionity HPC stations, and then up to 150 kW charging at fast Tesla Superchargers. Model 3 SR+ battery ABRP is starting to have a get a fair amount of data from Model 3 Standard Range Plus cars, which means we can also show a new charge curve for this one. It seems like Tesla has decided to put a hard cap on peak power at 100 kW for the SR+, at the same time extending the region with high power charging further. Since the SR+ battery capacity is rather small, this means that often supercharging is actually faster with the new curve - good news! BT70, the Model S70 battery Similar to the BT85, the BT70 has received reduced charging speed. We don't have tremendous amounts of BT70 data, but it is still enough for us to see a clear change. New model is released in ABRP.. Summary As usual, ABRP is building our car charging and consumption models on real-world data. Thanks to our fantastic users who donate data, we can continuously update those models, and we try to publish our findings here to give back to those who donated!

    If a Tesla: Share button in the left top corner of the plan, if smartphone or pc. "Tesla Nav" button in the left top corner of your plan, when you are using the Tesla internal browser. Both works only when you are logged in with your Tesla account.

    Description: Export Timetable as JPEG or PDF Use Case: I want to share my ride. So others can see it. Or save it for me. In the photo libary oder in Dropbox. For short planning it is ok to use pc screen capture. But for longer there is no good way.

    Yep, caused by a fix to the fix I put in for your lack of SoH data, you know the old Programmer song (to the tune of 99 bottles of beer): 99 little bugs in the code, 99 little bugs Take one down, patch it around 103 little bugs in the code In any case, should be all better now!

    Description: When planning a trip, the Total Duration column is empty except for the final trip time at the bottom. I would find it more useful to keep a running cumulative duration adding up all charging and driving accumulated up to each stop. Use Case: I'm currently planning a two day drive and trying to determine a good place to stop somewhere at or a little after the halfway point. I think it would be nice when planning any multiple day trip to look at the cumulative time to quickly plan an approximate time of driving per day.
