Abstract
一种估算电池包(10)SOC的方法、装置及电池管理系统，属于电池技术领域。电池包(10)包括不具有平台区的第一电芯(11)和具有平台区的第二电芯(12)，且至少一个第一电芯(11)与第二电芯串联。方法包括根据第一电芯(11)相对于第一电芯(11)的初始SOC的SOC变化量，及第一电芯(11)的标称容量，确定电池包(10)的容量变化量(S101)；获取第一电芯(11)的均衡容量以及第二电芯(12)的均衡容量(S102)；根据电池包(10)的容量变化量、第一电芯(11)的标称容量和第一电芯(11)的均衡容量以及第二电芯(12)的均衡容量和第二电芯(12)的初始SOC，估算第二电芯(12)的SOC，并根据第二电芯(12)的SOC确定电池包(10)的SOC(S103)。通过该方法可精确估算第二电芯(12)的SOC，解决了现有SOC估算不准确的问题。
