Original A123 cell (M1 specification sheet) - How big, how many and how heavy?
Description | Details |
Target Nominal Capacity | 22.69 kWhrs |
20C sag Capacity | 22 kWhrs |
Number | (83s12p) x 3 = 2988 cells (896.4V max and 821.7V nominal, 805V 20C sag) |
Weight | 2988 x .072 kg = 215 kg (would be 287 kg with 16p ~ 30 kWhrs) |
Possible A123 50V battery (containing 195 cells)
- 13 parallel x 15 series
- 49.5 V
- 29.9 Ah
- 1.48 kWh
- 13.65 kg + interconnects, packaging and BMS
We would want 18 of these in series to give us the following total pack:
- 891 V
- 29.9 Ah
- 26.64 kWh
- 245.7 kg + interconnects, packaging and BMS (should still be well under 300kg)
