At least that number matches up with your earlier stated 20 kW max regen in the Prius and 0.5 kWh usable capacity - that's a charge rate of 15C - that is only pushing the batteries about 8 times harder than the maximum allowable charge rate that Nissan allows (~50 kW during quick charge at lower SOC).DaveinOlyWA wrote:As far as the Prius. At max regen we could fully charge in 90 seconds to cover SOC. From 40-80%.
Would allowing another 30 kW of regen be useful on the Leaf? Sure would - but I suspect that Nissan thinks will wear the battery out too quickly, otherwise there's no reason to allow it. The motor / battery are capable of moving 80 kW+ when accelerating (though Nissan also cautions that frequent aggressive driving will also wear out the battery more quickly).
