My range keeps dropping?

Wed Sep 11, 2019 6:06 am

I bought a 2016 Soul EV+ back in June 2019. When I bought it the range was supposed to be about 92 miles on a full charge. Well, the first month of having the vehicle I would charge at a 100% of the battery (according to the dash) and the range would show anywhere from 78-80 miles after charging. Over the next 6-8 weeks the range after charging has gone from 78 miles, to 72 miles, then 68 miles, and this morning after charging overnight it says 65 miles.

I drive 59 miles one-way to work so this is concerning. Last night I left work with 68 miles range on a full charge (at work). When I pulled into my driveway I had 6 miles remaining until the car died.

Any explanations? I've read where I need to get a Statement of Health on the battery from the dealer.

Perhaps they BMS software got upgraded and then it resets to "new". It can take a while before the BMS learns the actual SOH.

You can ask a KIA dealer to get a reading or buy a OBD-II dongle and use the Soul Spy app to find out.

I am experiencing the same issue: range dropping; am also down to 65 miles

Could you add detail to the solutions and abbreviations? I am unfamiliar with them
BMS software
OBD dongle
Can one simply request a statement of health from a dealer?

can this be attributed to a software issue or is hardware a more likely culprit?

thank you

You can do that, they have equipment to read this.

It also depends on your usage and things like the weather. But I guess the most likely culprit is actually the hardware, especially if it is a car that had been driving for several years.

You can first drive around until you get below 18% and then recharge to full. That way the BMS will recalculate the battery health and use that for it's range prediction.

Have you asked a dealer to make a SoH report about your battery?
