Is it necessary for the lithium battery protection board to have an equalization function?

1. It is necessary to adopt a balanced situation: the storage time is longer in the case of battery processing, because different various static power protection boards and various battery self-discharge rates form the entire bundle, and the battery voltage has a significant pressure difference. , But with the same guarantee ability, the function of balancing the battery pack voltage under balanced conditions can achieve the effect of fully charged and fully discharged battery capacity, which makes the battery exert a huge impact. 2. Balance does not work: Many people think that the battery is used in the middle and late stages of the balance. The actual battery packs are used in the middle and late stages due to the different battery capacity losses, resulting in poor capacity. On the surface, the battery pack voltage of each string is the same, but due to the inconsistency of capacity, the low is often the single series protection and overcharge protection of the battery in the charge and discharge capacity, so the battery capacity is at low capacity A single string of batteries. Therefore, we should understand that the balance of the protection board is voltage, not a supplement to capacity. 3. Balance effect contradiction: balance usually has two elements: Answer: open balance voltage setting: set the following balance voltage, the protection board opens for a long time, and the balance effect is obvious, but while the balance protection board will have heat, balance The longer the time, the hotter it will directly affect the performance or damage the protection board; the balance voltage setting is high, the balance opening time is short, and the balance effect is not obvious. B: Balance current setting: If the balance current setting is too large, the balance effect will be obvious, but excessive heat will appear in the balance, which will damage the protection board. The balance current setting is small, the balance effect is not obvious, and the balance time is short. Conclusion: If the battery pack is within 13 strings, it is recommended not to bring the balance function, but the battery must be shut down strictly to achieve the consistency of battery capacity and internal resistance. Lithium batteries are afraid of storage, not afraid of use! Lithium batteries are suitable for single storage and not for overall storage. The battery pack should be carried out as soon as possible after completing the test in the hands of consumers.
