First of all, you need to know the voltage and capacity of the lithium iron phosphate battery used in electric vehicles. For example, 144v50ah
Then calculate the number of individual cells. For example, the battery of the 144v50ah above is 144v/3v=48, which is 48 50ah lithium iron phosphate cells
And then calculate the capacity of the lithium iron phosphate = 48*50 = 2400ah
Then calculate the price of the cells of this battery = 2400ah*15 yuan/ah=36,000 yuan.
Note:
1.
Lithium iron phosphate battery also needs a protection circuit to prevent the battery from overcharging, overdischarging and overcurrent. , and overheating, and a balancing circuit is required. The prices above are for battery cells only. Prices for protection and equalization circuits must be calculated separately.
2.
Before the cells are transferredFormed as a battery, they must be grouped according to capacity, internal resistance and voltage to ensure cell consistency. you can't just tap each cell. How much does ah cost to calculate the price.
