    • A method of calculating the state of charge of a power source, the method comprising the steps of; providing a plurality of equivalent circuit models; selecting an equivalent circuit from the provided equivalent circuits; calculating the input power to the equivalent circuit; calculating the losses from the equivalent circuit; determining an initial state of charge for the power source from the calculated input power and losses of the equivalent circuit; subsequently recalculating the value of one or more of the component parts of the equivalent circuit based on the temperature behaviour of the cell; and determining a state of charge using one or more of the recalculated component parts.
    • 一种计算电源的充电状态的方法,所述方法包括以下步骤: 提供多个等效电路模型; 从提供的等效电路中选择一个等效电路; 计算等效电路的输入功率; 从等效电路计算损耗; 根据所计算的等效电路的输入功率和损耗确定电源的初始充电状态; 随后基于电池的温度行为重新计算等效电路的一个或多个组成部分的值; 以及使用一个或多个重新计算的组成部分来确定充电状态。
