myEV: electric vehicle logger & app

The world’s first electric vehicle logger for individuals that can track energy consumption and SOC on (nearly all) production plug-in vehicles.

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..).

So when we turn to standard OBD loggers we find our vehicles on the “not-compatible” list.

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.

Making EV Data Accessible, Shareable, & Comparable

Get real-world data on your trip’s efficiency and starting & ending state-of-charge, as well as a lifetime summary that aggregates key metrics and provides your estimated battery health level. The app makes it easy to compare with others in your area or on your team, and share these results with your friends.

Give me data!

Public Charging Etiquette

EV owners band together & believe in creating good karma. Placing the personalized QR code window sticker on your vehicle allows others in the myEV community to kindly ask if they can unplug you at a public charging station when they are in need. That’s good karma.

I want to be a better person!

More Information

Why would you want to log your EV?

Here are the top 5 reasons we’ve heard from fellow EV owners:

  1. I want more data than what the dash shows me (ie. % SOC, not bars)
  2. I want to keep an eye on the health of my battery.
  3. 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.
  4. The other data system you use went down. Again.
  5. 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.

EV Teams

What’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 Hardware

The Carma Hardware Family

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.


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 and we can confirm vehicles/timing for you. Most of the vehicles will be added to the list before the October ship date.
