It seems to be fairly common knowledge that if you want to keep your battery in good condition, the key is to keep the state of charge at a fairly modest level, and avoid regularly charging above 80-90% or allowing it to drop below 10 - 20%. But what about rate of charge/discharge? How does how 1 drive and charge affect battery life? Does charging slowly (using the 40amp//9.6kw onboard charger) reduce the strain on the battery when compared to using a Chademo or SuperCharger? I.e. is it better to charge slowly or quickly? What about driving style and speed? Presumably rapid acceleration can put some additional and unnecessary wear on both the battery and motor. But what would be considered 'too hard'? And what about sustained power / speed? Driving on a flat road with a constant 20kw output seems to be sufficient for around 100km/h, and 130km/h at 30kw and 160km/h at 60kw. 100-130km is probably typical for highway speeds, but does driving at 130km/h have a greater impact on the wear of the battery and motor over 100km/h? How about 160km/h? One would assume that the faster you drive the harder it is on the battery, if Chademo charges at a rate of 50KW and SuperChargers at 100kw+ , surely the battery can handle a discharge rate of at least as fast? I think it is probably safe to say that one could drive normally and that would be fine for the battery and motor. But would driving slightly faster increase the wear, and reduce the lifespan or would the difference be fairly negligible? Appreciate any feedback if anyone knows the answer.
