A few questions. I'm starting to get the knack of using my 4kWh system. After driving 120 miles yesterday with Enginer switched on about 80% of the time, the red light never came on. I was expecting depletion at 40 miles.
After recharging, my kill-a-watt says the charger used 2.9kWh. I am guessing there is some overhead for the charger, so 2.9kWh input is not exactly 2.9kWh added to the pack. What should be the full recharge kWh reading on the kill-a-watt from red-light to charger shutdown for a 4kWh pack? It should be about 5, right?
During my drive, and I have 2G prius, the converter output fluctuates from 2A to about 12A, but mostly on the low end. SOC stays at about 68-70. Does the Enginer pack get overly cautious about dumping amps into the stock battery when the temperature is too cold?
Usually my cells show nearly balanced just after recharging. But I also saw in the morning about 7 hours after recharge completed, my low/high is 3.29/3.40. Is that OK and do you expect drift like that while sitting several hours?
