Re: L2 fast vs slow charge ~ battery life

Thanks Art, When i said Summers vs Winters, i was mainly referring to the temperature of the battery As some videos of Tesla suggest, the car tries hard to increase battery temp , while charging, even if that means efficiency is lowered by generating heat. Apparently Batteries like to be charged whe...

But the requirement to have the front door opened , to open the back door , makes a good triangle, with the person trapped inside. in the garage. , its a interesting puzzle with kids.

L2 fast vs slow charge ~ battery life

For all those, who charge mostly overnight and charging speed is not an issue what is the better option to charge at L2 in USA. Reduced 15Amp or 32 Amp ? What is better for battery life ? I know 220 volts is like 2% more efficient than charging at 110 Volts, so 22Volts wins over 110 volts Also does ...

Re: DIY HV Battery upgrade

At least it's being done in Leafs on almost industrial scale by third party workshops in Ukraine, and with great success. There are plenty of reports on Youtube. Haven't seen anything re i3 though. Did Nissan not say , that the batteries are not up-gradable. The 24kwh cannot be replaced by the newe...

Re: DIY HV Battery upgrade

Yes, surely the software configuration on which the BMS relies will need to be adjusted to make things work properly. Also note the battery chemistry is changing with each generation , so the charging , discharging characteristics and curves also change. All in all, the best Evs are the most optimiz...

Re: AC Continues to Run

I had the same issue in both my i3
Turing AC off after few minutes of use , does not turn it off many a times
It will also happen , when its cold and there is no need to cool battery after say 3 mins of driving

I conclude , i think its a bug.....
