Given the 30 kW seems to heat up faster during DC quick charging , I can easily generate 8 bars of temp after two successive fast charge sequences What I never see during normal driving , is any reduction in temp bars even with under 60 mph driving , but sometimes I only see it after switching...

its still not clear, what I mean is that if you could find a bigger DC charger for the leaf, surely the BMS limits the max charge current to a value that Nissan have decided in the maximum. I design with Lithiums, no one allowed uncontrolled mac power charging of Lithiums, unlike lead acid...

Are people saying that Nissan will allow the chademo to put in whatever max it can , are Nissan allowing 4-5 C. Charging ? I find that hard to believe

Does anyone have a handle on the Nissan Leaf DC charge cycle, what is the max allowable constant current phase power allowable, i.e. what proportion of C is Nissan allowing do they actually taper the power in the CC phase for safety ? what cell voltage do they transition from CC full...

you do realise the contradiction in what you said (a ) it will taper back the current when it reaches the same voltage as the smaller battery it just takes longer to get there at the same current because it's a larger batter (b ) but because it's charging at the higher rate for longer it...

The charging strategy could be either. I notice on another thread , it's claimed the Nissan have move the CC/CV transistion further up the curve for the 30 kW battery. However I doubt that , given the safety orientated aspects of nissans charging strategy. ( and the lack of slope of voltage...

That university paper you refer is , is incredibly flawed. Not only does it pull assumptions for the air , it arrives at incorrect conclusions. Quite frankly it's a typical post grad master thesis and very poor to boot. It just not a good reference Remember the internal resistance of a...

I'm glad mad_lad ( Scorpion) , you're seeking and getting a better understanding of li battery charging.
