Abstract

一种电池状态估算方法，涉及电池技术领域。该电池状态估算方法包括：获取电池中多颗电芯中每颗电芯的第一电芯状态参数(S101)；在存在多个电芯分区的情况下，判断属于一个电芯分区的每颗电芯的第一电芯状态参数是否位于该电芯分区对应的第一电芯状态参数范围内(S102)；若位于该电芯分区对应的第一电芯状态参数范围内，根据电芯分区对应的目标电芯状态参数估算每个电芯分区的电芯状态(S103)；根据电芯状态估算电池的电池状态(S104)；其中，属于同一电芯分区中的各颗电芯的第一电芯状态参数的偏差在第一偏差范围内。通过该电池状态估算方法，能够降低电池状态估算的误差，提高对电池状态估算的准确性。
