STATE OF HEALTH OF A BATTERY

A method for constructing a chart showing correspondence between a rapid discharge and a slow discharge for a measurement of wear of at least one electrochemical cell, comprising a measurement phase that includes a training sequence (100), followed by a characterisation sequence (200) and an ageing phase (300). Each of the sequences comprises charging-relaxing-discharging-relaxing under controlled conditions and is repeated with different conditions. The time of each discharge is measured. The ageing phase (300) comprises alternating charge and discharge without intermediate relaxation and is implemented before each repetition of the measurement phase, such that an actual capacity (Cv) is obtained for a plurality of pairs of imposed parameters. 用于构建快速放电与慢速放电之间的关系表以测量至少一个电化学电池的损耗的方法，所述方法包括测量阶段和老化阶段(300)，所述测量阶段包含训练序列(100)，之后是表征序列(200)。每个序列包括受控条件下的充电-休息-放电-休息，并且使用不同条件重复。测量每次放电的时间。所述老化阶段(300)包括没有中间休息的充电和放电的交替，并且在所述测量阶段的每次重复前进行，以针对多对施加的参数获得真实容量(Cv)。
