Battery -Technical comparison of OPZV lead elements against lithium-LiFePo4 technology element.
Basis of comparison –
Lifepo4 106.5 Ah 3.2 Volts x 16 units = 1700 AH LiFePo4 Element Type 106.5 Ah 3.2 volts
Summary of technical data:
Pack 48 volts lithium iron
87 KW at 100%
74 KW use
3500 to 5000 cycles
528 Kg x 0.53 M3 (530 liters)
Lead cell equivalence OPZV 2 Volts Gel:
Reference temperature battery Lead 20 ° C
Fast discharge 3C reference – 30% capacity
Number of cycles at 50% DOD 2500/3000
Estimation initial capacity lead OPZV:
Cell 2000 Ah x 2 = 4000 Ah
4000 Ah – 50% Dod 3000 cycles = 2000 Ah
2000 Ah – 25% capacity on the C3 curve
Real working capacity 1500 Ah x 48 volts = 72 KW in C3
96 KW in C 10
Package weight 152 Kg x 2 x 24 = 7.296 Tons
Volume of the pack – element 70 liters x2 x24 = 3.36 m3
Purpose result
| Plomb OPZV 4000 AH | LiFePo4 1700 Ah |
| 72 KW -C 3 | 74 KW |
| 7.3 tons | 0.528 Tons |
| 3.36 M3 | 0.530 M3 |
| 101 kg /KW/h | 7.1 Kg /KW/h |
