Lithium battery protection: short circuit protection, overcharge protection, over-discharge protection, over current protection, equalization, with SMBus communication, etc. We are happy to customize the charging and discharge current rate based on customer demands.
Due to the consistency problem of lithium batteries, if they are connected in series in the same system (such as ternary or iron-lithium), it is also necessary to select those with the same voltage, internal resistance and capacity for grouping. Batteries with different voltage platforms and different internal resistances are used in series, which will cause a certain battery to be fully charged first and then discharged in each cycle.
If there is a protection board and there is no failure, the capacity of the whole group will be reduced. Damage to the battery caused by overcharging or overcharging.
If different capacities or old and new lithium batteries are used together, there may be liquid leakage, zero voltage and other phenomena. This is due to the difference in capacity during the charging process, which causes some batteries to be overcharged during charging, and some batteries are not fully charged. When discharging, some batteries with high capacity are not fully discharged, while those with low capacity are over-discharged. Such a vicious cycle, the battery gets damaged and leaks or has low (zero) voltage.
