A battery arrangement (1) for producing direct current comprises at least one direct current input (ACIN) for connecting the battery arrangement (1) to at least one alternating current source (ACS1, ACS2, ACS3, ACS4) comprising at least one phase (A, B, C) and at least one rectifier unit (ACDC) to be connected to the alternating current input (ACIN) for converting alternating current to direct current. The battery arrangement (1) further com-prises at least one rechargeable battery unit (AU1, AU2, …, AUn) connectable to the at least one direct current output (3) of the rectifier unit (ACDC) for recharging the battery unit (AU1, AU2, …, AUn) with direct current pro-duced by the rectifier unit (ACDC), and a protection unit (PU1_A, PU1_B, PU1_C) connected to each phase (A, B, C) of the alternating current input (ACIN).
