I use the onboard timer to charge the 40 kWh battery to 80%. For the first 18 months I owned the car it reliably charged at the rate of 15% per hour, so four hours would take it from 20% to 80%. Recently that same 4 hour setting results in the battery ending near 100%. The other day the battery was at 46% and I set the EVSE for 2 hours. That should have taken it to 76% but instead it ended up at 96%. That amounts to 25% per hour or 10 kWh. Using Ohm's Law that amounts to 40 amps at 250 volts. The breaker on the EVSE is 30 amps so that charge rate for 2 hours is impossible. Is the timer not shutting off at the right time? Any ideas?
Thanks
