The present invention relates to a method for charging a traction battery of an electrically powered motor vehicle, in which a first target value for a first battery charge level is specified for a start of the motor vehicle in which the traction battery, provided that its battery charge level is smaller than a second target value, to avoid aging processes, is charged in a first charging process to a second battery charge level which corresponds to a second target value, which second battery charge level is smaller than the first battery charge level, and in which the traction battery in a second charging process is charged to the first battery charge level, wherein the start time of the second charging process is set as a function of a specific departure time, the first target value and the second target value, or wherein the second charging process is started on the basis of a start signal which is output by the user as a result of an interaction of the user with a terminal. The invention further relates to a charging device for charging the traction battery according to the method and to a motor vehicle with such a charging device.

    本发明涉及一种用于给电驱动机动车的牵引电池组充电的方法,其中针对用于机动车的行驶开始的第一电池组充电状态预先给定第一额定值,其中为了避免老化过程,牵引电池组只要其电池组充电状态小于第二额定值就在第一充电过程中被充电到小于第一电池组充电状态的与第二额定值相对应的第二电池组充电状态,而其中牵引电池组在第二充电过程中被充电到第一电池组充电状态,其中第二充电过程的开始时间点根据所确定的出发时间点、第一额定值和第二额定值来调整,或其中第二充电过程基于启动信号来开始,启动信号由于用户与终端设备的交互而由终端设备来输出。本发明还涉及一种用于按照该方法来给牵引电池组充电的充电设备以及具有这种充电设备的机动车。
