The invention relates to a method for charging an energy store (14) of a motor vehicle (10) from an initial state of charge (Z1) of the energy store (14) to a final state of charge (Z2) of the energy store (14) at a vehicle-external power source (26), a control device (12) controlling the charging according to a first charging mode (L1), in this way, the energy store (14) is charged by the external energy source with the first power (P1) and according to the first overall efficiency ([eta] 1). The control device (12) determines whether an activation request (54) for activating a second charging mode (L2) representing the energy-saving mode (L2), which is proposed by the user (36), has been received, and at least if the activation request has been received, the control device (12) controls the charging process in accordance with the second charging mode (L2) in such a way that the energy store (14) is charged in accordance with a second overall efficiency ([eta] 2), the second overall efficiency is higher than the first overall efficiency ([eta] 1) and lower than the possible highest overall efficiency ([eta] max).
本发明涉及一种用于在车辆外部电源(26)处将机动车(10)的蓄能器(14)从蓄能器(14)的初始荷电状态(Z1)充电直至蓄能器(14)的最终荷电状态(Z2)的方法,控制装置(12)如此根据第一充电模式(L1)控制充电,使得以第一功率(P1)并且根据第一总效率(η1)通过外部能量源为蓄能器(14)充电。控制装置(12)确定,是否已经接收到由用户(36)提出的用于激活代表节能模式(L2)的第二充电模式(L2)的激活请求(54),至少在接收到激活请求的情况下,控制装置(12)如此根据第二充电模式(L2)控制充电过程,使得根据第二总效率(η2)为蓄能器(14)充电,第二总效率高于第一总效率(η1)并且低于可能的最高总效率(ηmax)。
