We plug-in vehicle owners are a social bunch.
We love our vehicles. We wave at each other when we drive by. We sometimes take way too much time answering people who ask "Like it?"
We tend to have a very high interest in numbers. Especially our mile/kWh, MPG-equivalent, and our real-world range. The existing data portals from manufacturers don't give all the info we'd like and more importantly they separate us into silos (LEAF portal, Volt portal, etc..).
Where's the love?
Here it is. A logger that IS compatible with nearly every currently available production plug-in vehicle in North America (and many of the vehicles internationally).
We've been logging these vehicles for a few years for fleets, and with your backing, we'll finish adapting that technology to make the world's best logger & app for EV owners. Through the app EV owners can tell their personal EV story by being able to track, share, cheer, and connect.
Our technology has been featured in:
A few screenshots from the app are provided below. We will launch both Android and iOS versions.
first pair of screenshots you see the Last Trip summary that provides
the real-world numbers from the last trip. This includes a ranking
compared to all logged trips for your vehicle, compared to those on your
team (more on teams later) this week and compared to others of the same
model in your area. Additionally it gives you the starting and ending
SOC, as well as the ability to post the result to the social networks of
The lifetime summary page provides summary results for all data we've logged on your vehicle. Again, it ranks against both your team and owners of the same model in your area. Of interest to many owners will be the Estimated Battery Health value. Fortunately we have an expert in battery degradation in hybrid & electric vehicles on the team (got his Ph.D. beating up EV batteries). Please note, we can estimate battery health on all the vehicles listed EXCEPT the Accord PHEV and the Porsche... we don't get quite enough signals on those models, yet.
The next screenshots are specific to public charging etiquette. Each backer that receives a myEV logger will also receive a window sticker.
The window sticker includes a personalized QR code. This can be used
by others in the myEV community to a) ask if they can unplug you at a
public charging station in a privacy-protected way, b) give you an
electric fist-bump, and c) request a connection to share info.
last set of screenshots show the unlock screens and one of the unlocked
features. You and your team will collectively rack up EV miles. As
you hit EV mile thresholds additional features in the app will unlock.
The unlock feature shown below provides a histogram of charging
How does myEV compare to other loggers?Click here to see a benefit comparison chart. *Please note: this chart was made to highlight the benefits of the MyCarma myEV contrasted against other loggers, and isn’t intended to be an absolute comparison. Other loggers (such as cellular) may have their own functionality & benefits, such as remote lock/unlock, GPS position etc. Using a Y-harness, myEV can also be run in parallel with other loggers.
Why would you want to log your EV?
Here are the top 5 reasons we've heard from fellow EV owners:
- I want more data than what the dash shows me (ie. % SOC, not bars)
- I want to keep an eye on the health of my battery.
- I want to track my range throughout the year to see the impact of the weather, and to compare this to other EV owners in my area.
- The other data system you use went down. Again.
- I love my car and want to share my results with others that are in the
EV community, and those that are considering becoming EV owners!
We've been listening. And by adapting our fleet hardware and decodes (ability to log EV signals) we can give the community what it's looking for.
Decoding and Cleaning
The challenge with logging EVs is getting the signals. Most after-market loggers use emissions-related signals. That's why they can't get the energy/battery info that we all want. To work on EVs you need to be able to log the non-standard signals. We do this.
Additionally, since they're non-standard, each manufacturer uses different signals that can have slightly different meanings. For instance, battery power from one manufacturer can mean something slightly different than battery power from another. So in addition to decoding the signals they need to be normalized to be able to share across vehicles. It's taken us a while, but we've figured this out.
The Teams & Draft Feature ListWhat's this about teams? Well, with EV owners being so social, we want to enable owners to grow together. Teams of up to 20 people will be linked. Racking up EV miles together, you will have app features unlocked as you hit key milestones. A draft feature list is shown below. Additional signals/data will be available for specific vehicles.

The prototype hardware and firmware for MyCarma myEV is based on two of our designs we currently have in production here in North America.
The dad is the FleetCarma hardware that is currently installed in fleet EVs all over the world. The cellular version is more popular - it has a good ROI for a fleet needing to maximize the benefits of EVs, but is a bit pricey for an individual enthusiast. So it's a bit of overkill for a personal EV logger.
The mom is the CrossChasm OpenXC logger. It has a similar form-factor to the manual (non-cellular) version of the FleetCarma logger. The hardware is slightly different though, and it has a Bluetooth chip. This logger is used by app developers to make use of the extra signals Ford has given access to. Unfortunately, this hardware and firmware can't make use of FleetCarma's decodes for electric vehicles.The daughter, a prototype, has been created to combine the electric vehicle capability of the dad, with the Bluetooth capability of mom. With your backing, we will be able to take that prototype into full production and complete the necessary testing with the app.
We have the myEV hardware and firmware prototyped. If the campaign is successful, the production-intent design will be completed and sent to production.
Additionally, the unlock features that will be added to the app will be established based on the feedback of the backers. These will be integrated into the app.
While there remains additional testing and production timing, the balance of the work is scheduled to be completed over a three month period.
Are you MyCarma? Or CrossChasm? And what's a FleetCarma?
One team. One goal. Three parts... and because an engineer leads our marketing efforts, three names (thanks Matt). So we're all three. Read more about us in the full bio if you're so inclined.
...oh yeah, and if you're wondering, our goal is to make high-efficiency vehicles a reality.
Campaign UpdatesJune 1st update: Q&A was added below. Please keep the questions coming!
June 2nd update: Draft feature & upgrade list.

July 22nd update: Our campaign has successfully ended; thanks for backing us! To get more info, you can now visit our website.
We've had some great questions that have come up a few times. Here's a quick Q&A.
Can I use the myEV device in parallel with another device?
Yes. You'll need a y-harness. Since the myEV device is fully passive on most vehicles (doesn't create signal traffic like an OBD device does) it plays nicely with others.
My vehicle (i3, Outlander PHEV, RAV4 EV, ...) isn't on your list. Will it be?
For most of these, yes. Shoot us an email at email@example.com and we can confirm vehicles/timing for you. Most of the vehicles will be added to the list before the October ship date.
Are you going to also show "X"? (X can be any other signal/value that may be of interest)
With the signals we're able to get, there are a number of things we can include. We want to prioritize what get's included/added with the backers. We'll get the draft list posted here in the next day to give you a better idea of what we are planning to add.
Please keep the questions coming! And thanks everyone for your time and backing!
