OPZV Battery

About This Project

New Batteries for Telephony project

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
