Consistency of power lithium battery pack

Consistency of power lithium battery pack Lithium-ion power lithium-ion battery is a key core component of new energy vehicles. The consistency of its battery packs is particularly important in terms of power lithium-ion battery pack life and vehicle safety. . In actual use, due to the difference between the battery packs, a single cell in the battery pack fails first, which will form a donomy effect, causing the entire battery pack to fail as a whole, seriously affecting the safety and service life of the lithium battery pack, and Threaten the normal use of the entire vehicle. Because the inconsistency of the battery comes from the internal resistance, capacity and SOC of the battery, and the traditional consistency evaluation method and the voltage consistency other than the equalization method are used as the control target, which does not effectively increase the usable capacity of the battery pack, so it cannot improve the consistency of the battery pack. Sexual problems have an adverse effect on the use of battery packs. After research, the SOC is used as the reference object of the balance, the balance object is relatively fixed, the balance time is fully utilized, the balance utilization rate is improved, and the balance current capacity is reduced.
