INL did detailed testing of most of the OEM offerings, including two separate i-MiEVs. Interesting conclusions. The pack is capable of over 200 kW discharge pulses fresh off of charge, and over 150 kW all the way down to 40% SOC, with about 100 kW down at 80% discharge.
The LEAF pack, however has much more ampacity. It can make over 300 kW when full, and still turn out over 100 kW at the end of test...
It looks like 24 kWh of LEV50 cells would hang right in there with a LEAF pack. but the LEAF power density and energy density are both higher. 99 W/h per kg for iMiEV, 140 Wh/kg for LEAF.
