I am very interested in knowing the depletion rate of my Hybrid battery capacity. I own a 2013 Ford Fusion Hybrid. Are battery depletion rates and usage metrics available via the cars interface and can Automatic add monitoring to rate battery capacity of hybrids and evs?

Hi Michael,

Yes, hybrid battery capacity information is available at the OBDII data link connector. Currently we utilize the OBDII data surrounding the internal combustion engine, but I will pass your request on to the design team.

Thanks,

Ian

Ian,

What was the outcome of your talks with the design team?

Hello Brent! I checked with our design team, and we don't have any current plans to implement this feature, but the idea is still "under consideration." If things change, we'll be sure to update this topic.

I live in Arizona and battery capacity loss in high heat is still a concern for me and very telling issue with regard to the success of EV in general. I full well understand the reasoning by the manufacturuers to NOT expose this metric to the general public. I can only assume that in areas like where I live this could have an adverse effect on sales and trade in behavior of EV related vehicles.  Personally I am just trying to gauge when I should trade my Fusion in. I am a software developer and have been toying with the idea of getting an Arduino OBDII data link connector and peeling off the data however I have not been also to find how to get at this data yet.

You bring up some really interesting points, Michael. You may already be aware of the standard OBD-II PIDs, but if not, check out this page. Here's a related topic on what vehicle sensors we currently read (using generic PIDs).
