    • A method for characterizing the health of a rechargeable battery includes measuring initial condition parameters of a rechargeable battery prior to the battery being placed into service. A baseline normalization of the initial condition parameters is performed using a standardized relationship data set for a norm battery to generate baseline normalization coefficients to normalize the initial condition parameters to the norm battery. Run-time condition parameters of the battery are measured after the battery is in service as part of a continuous built in test system. The run-time condition parameters are normalized using the standardized relationship data set for the norm battery and the baseline normalization coefficients to generate normalized run-time condition parameters for the battery. The normalized run-time condition parameters are then compared to the standardized relationship data set for the norm battery to calculate a state-of-charge and state-of-health for the battery as the run-time condition.
    • 用于表征可再充电电池的健康的方法包括在电池投入使用之前测量可再充电电池的初始状态参数。 使用针对范围电池的标准化关系数据集来执行初始状态参数的基准线性化,以生成基准线性系数,以将初始状态参数归一化为规范电池。 在电池使用后测量电池的运行状态参数,作为连续内置测试系统的一部分。 使用针对标准电池的标准化关系数据集和基线归一化系数对运行时状态参数进行归一化,以生成电池的归一化运行时状态参数。 然后将规范化的运行时间条件参数与标准电池的标准化关系数据集进行比较,以计算电池的充电状态和健康状态作为运行时间条件。
