Abstract (en)
[origin: WO2022118070A1] The invention relates to a charging system (2) for an accumulator (48) in an electric vehicle, comprising: a voltage converter unit (3) and an accumulator unit (4), wherein: the accumulator unit (4) is designed to be supplied with electrical energy via two supply terminals (44, 45); an accumulator (48) of the accumulator unit (4) has two terminals (481, 482) which are detachably connected to the supply terminals (44, 45) via a second and a third isolating switch (46, 47); the voltage converter unit (3) is designed as a structural unit which is separate from the accumulator unit (4) and is connected to the accumulator unit (4) via three terminals (31, 32, 33); and, in the connected state, within the accumulator unit (4) two of the three terminals (33, 32) are connected to the two terminals (481, 482) of the accumulator (48) and the third of the three terminals (31) is connected to one of the supply terminals (44, 45), and within the voltage converter unit (3) the third of the three terminals (31) leads via a first isolating switch (36).
