Abstract:
衡量电池状态的参数主要有SOC和SOH，SOC (state of charge)反映电池剩余容量，SOH (state of health)反映当前时刻电池存储电能的能力，表征了电池的健康程度，两者都是描述电池性能和状态的关键参数。但是SOC和SOH是电池的内特性，不能直接测出，因此只能通过电压、电流等外特性参数间接估计获得。
State of charge (SOC) and state of health (SOH) are two parameters to measure the states of bat-tery, where SOC reflects the remaining capacity of the battery and state of health (SOH) reflects the capacity of the battery to store electric energy at the current moment. Both are key parameters to describe the performance and status of the battery. However, SOC and SOH are internal characteristics of the battery and cannot be measured directly, so they can only be estimated indirectly by external characteristics such as voltage and current.
