Specifications
- Usable Energy = 107 kWh (Total = 111 kWh)
- SoC Window = 96.4
- Nominal Voltage = 375 V
- Nominal Capacity = 296 Ah
- Peak Power = = 422 kW10s
- Configuration
- 102s 2p
- Total Cells = 204
- Charging
- Peak Power = 250 kW
- 10 to 80% SoC time = 30 minutes
- Pack Mass = 664.7 kg
Note: the pack energy density is given as 167 Wh/kg and the total energy is given as 111 kWh in the EPA filing. Hence the pack mass = 1000 x 111 / 167 = 664.7kg
