Abstract (en)
[origin: WO2022136044A1] The invention relates to a method for charging a stored energy source (4) of a vehicle (3), wherein - a charging process of the stored energy source (4) is carried out using a charging device (6) of the vehicle (3), - in a first phase of the charging process, the stored energy source (4) is charged with a first DC voltage (U1) of the charging source (2) in accordance with a charging current (IL) of the charging source (2), - a battery voltage (UBatt) of the stored energy source (4) is determined during the charging process (6), - the battery voltage (UBatt) of the stored energy source (4) is compared with the charging voltage of the charging source (2), - a voltage converter (7) is operated in accordance with the comparison of the battery voltage (UBatt) with the charging voltage, wherein - in a second phase of the charging process following the first phase, the stored energy source (4) is charged with a second DC voltage (U2) of the voltage converter (7) in accordance with a choke current (ID) of the voltage converter (7). The invention also relates to a charging system (1).
