My EV System warning light lit up after attempting to quick-charge at a Blink QC unit I've used a few times in the past. I've never had that happen, and the QC unit terminated the charge, reporting that an 'error' had occurred. I tried one more time, hoping it was a fluke, but it came back with the same error.
I could still drive the car with the light on. Went to the nearby Nissan dealership to start an L2 charge (needed it to get home) and ask them what was going on. The EV warning light was still lit, and I couldn't start the L2 charge up. The three blue dashboard lights wouldn't light up.
The service manual seems to have hundreds of conditions that can cause this light, from CAN bus errors to individual cell errors, depending on the DTC code.
I ended up leaving the car there, and they graciously got me a rental car. I'll let you know what they find out.
