For models with a range of more than 400 kilometers, the battery capacity is basically more than 60 kWh, which means that the battery price is more than 90,000. However, the current range of mainstream new energy vehicles is about 300 kilometers, so the battery price is roughly 60,000 to 80,000, which is still relatively expensive.
Notes
Power loss caused by improper operation or illegal modification will significantly shorten battery life.
It is worth mentioning that the batteries of a batch of domestic new energy vehicles are about to reach their usage limit, and will also usher in the first large-scale wave of recycling old batteries.
In some places, the price of lead acid batteries is in AH, for example 10 yuan/AH, while the price of lead acid batteriesies lithium-ion is generally calculated in WH. are they compared?
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. The prices of protection and equalization circuits must be calculés separately.
2.
Before the cells are made into 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.
I don't know about lead acid batteries! Lithium batteries are counted as AH! For example: if an 11.1V 10Ah lithium battery is worth 8 yuan/AH, it is 10Ah*8 yuan*3 strings=240 yuan. Lithium battery per AH is the price of a single lithium battery! 11.1V corresponds to 3 lithium batteries connected in series.
