Just found AI company called Recurrent that seems to be a mixed bag for an EV owner. If you signup that track your EVs battery performance and when you go to trade in, It claims to use AI TO prove the health of youR EV battery as it will influence the value of your vehicle.

I certainly would use there service to learn about the Volts long term reliability and use it to verify a vehicle I wanted to purchase. I doubt I would allow them to track my VIN

interested on thoughts of anyone who has signed up.

I quickly read this "SPONSORED POST" article and I still don't understand where they get the data from for the report. You must manually enter it.

In a Volt's case, they'd have to evaluate total mileage by both ICE miles or "EV" battery only driven miles.

It seems like a way for EV owners to give them data for their business "collection" purposes which they use to generate reports.

Recurrent lets you monitor and compare the battery health of a current or prospective EV for free

Recurrent offers detailed reports monitoring EV battery health monthly for current owners or one time for prospective EV buyers.

Aside: From my Tesla Model X, I have a $50/yr membership to TeslaFI that is connected to car (essentially same API as phone uses). It gives me an idea of my battery relative to other similar models (29 per below currently) with similar mileage.

I've been using this service for almost two years now and find their monthly reports semi-useful. I don't mind sharing information about the car with the company. Their reports did cause one minor behavior change for me. Previously I would always plug the car in when I get home, no matter how much of the battery capacity was used. I know that Volt tries to optimize battery usage, so that the same cells are not used all the time. But Recurrent's recommendation is to keep the battery between 30 and 80%. So unless I have a longer trip planned, I no longer plug in unless the battery is less than 50%. I know this is mostly relevant for full EVs, but since my daily drive is usually under 15 miles, I figured the logic applies to Volt as well. Below is a sample snapshot of a portion of their report. When the time comes to sell the vehicle, their price snapshot maybe useful also, who knows.

It does, but the Volt's already taken care of it. It is already engineered to enforce about a 20%-85%, and hide that fact. The battery graph's "0-100%" represents only that middle range in use. Plugging the Volt in also allows the car to keep the battery warm in the winter and cool in the summer, and can supplement the cabin preconditioning with wall power, saving more of the battery power for actual driving instead of heating the battery and the cabin with electricity you might more want to use for actually going somewhere.

It sounds like they are making little or no distinction between how a Volt's battery is engineered vs. other EV's.

I’ve used their battery reporting and yes, I don’t think it’s designed for the charge programming of the Volt as opposed to full battery usage EV’s. It’s too bad that they can’t take into account the charge parameters of the Volt; it wouldn’t be that hard to do.

Agree and given that they are marketing their service as AI driven predictive modeling they need to at least understand the vehicles they are issuing predictions on. Have any of the Volt users contacted them to determine if they take the Volts more narrow allowable min and max SOC into account?

Maybe they are Tesla purists who don't consider the Volt an EV, so no need to account for it.

I haven’t yet but will try

This doesn't look useful for my Gen 1 Volt. No uplink is available, so I would have to manually enter data, I assume from the GOM. In my case, the GOM consistently underestimates actual range, so this app might understate my battery range and consequently, battery life.

It gives you a rough idea of how your battery is performing compared to an average given the age of the battery. As noted I wish it would recognize the buffering of the Volt battery.
