The invention relates to a method and a device for determining the state of health of a battery for a vehicle. The method comprises the following steps: charging the battery up to a predetermined target voltage (40) in a first charging phase (P1) of the battery; determining a first voltage value (50) of the battery at a first predetermined time (60) in a relaxation phase (P2) of the battery after the predetermined target voltage (40) has been reached; determining a second voltage value (55) of the battery in a relaxation phase (P2) of the battery at a second predefined time (65) different from the first predefined time (60); information about the state of health of the battery is determined on the basis of a change in the second voltage value (55) about the first voltage value (50), and the information about the state of health of the battery is used in the vehicle and/or in an external server.
本发明涉及一种用于对用于运输工具的电池的健康状态进行求取的方法和设备。该方法包括下述步骤:在电池的第一充电阶段(P1)中对电池进行充电直到预先规定的目标电压(40);在到达预先规定的目标电压(40)之后在电池的松弛阶段(P2)中,在第一预先规定的时间点(60)求取电池的第一电压值(50);在电池的松弛阶段(P2)中在与第一预先规定的时间点(60)不同的第二预先规定的时间点(65)求取电池的第二电压值(55);基于第二电压值(55)的关于第一电压值(50)的变化来求取关于电池的健康状态的信息,并且在运输工具中和/或在外部的服务器中使用关于电池的健康状态的信息。
