1. Consistency
If the lithium-ion battery pack with poor consistency has a protective plate, according to the principle of the bucket, its capacity will be the lowest, so that the entire battery pack will neither fully release electricity nor absorb enough electricity due to one cell. Electricity, over time, the life of the battery pack is short. If the battery pack is not equipped with a protective plate, not only will there be capacity loss, but also safety problems, overheating and explosion may occur.
2. Self-discharge rate
Due to the large power consumption of the lithium iron phosphate battery pack, it is required that the self-discharge rate of the battery pack should be less than 2% per month. To achieve this, the above-mentioned consistency requirements are essential. The detection method of the discharge rate is: charge the batteries with the same capacity and let them stand for one month, and then measure the electric capacity value.
3. High magnification
A battery pack that can withstand high-rate charge and discharge has a strong ability to quickly charge and discharge. For lithium iron phosphate batteries, it must be able to quickly charge and discharge to meet its requirements for lithium ion batteries.
4. Long life: As a general requirement, the lithium iron phosphate battery pack still has 85% capacity after 2000 discharges at 1C, and 80% capacity after 3000 discharges. Of course, each manufacturer has different standards due to different process levels and materials.
