The invention relates to a charging device (1) and to a method for operating such a charging device (1). The charging device (1) has at least one first and one second charging connection (2-1, 2-2), a plurality of power converters (4-1, 4-2, 4-3,..., 4-N) and a primary switch arrangement (5) connected between the charging connections and the power converters (4-1, 4-2, 4-3,..., 4-N). The primary switch arrangement (5) is designed to connect a first group of power converters (4-1, 4-2, 4-3,..., 4-N) having a variably selectable first number of power converters (4-1, 4-2, 4-3,..., 4-N) to the first charging connection (2-1) and to connect a second group of power converters (4-1, 4-2, 4-3,..., 4-N) having a variably selectable second number of power converters (4-1, 4-2, 4-3,..., 4-N) to the second charging connection (2-2), depending on control signals from the control unit (6) which are received at the control inputs. According to the invention, the control unit (6) is designed to check a rapid disconnection condition for each charging connection (2-1, 2-2), to identify a causative charging connection (2-1, 2-2) of the first and second charging connections (2-1, 2-2) in the event of a positive checking result of the rapid disconnection condition, and to disconnect the first group of power converters (4-1, 4-2, 4-3,..., 4-N) and to leave the second group of power converters (4-1, 4-2, 4-3,..., 4-N) connected if the causative charging connection (2-1, 2-2) is the first charging connection (2-1), and to disconnect the second group of power converters (4-1, 4-2, 4-3,..., 4-N) and to leave the first group of power converters (4-1, 4-2, 4-3,..., 4-N) connected if the causative charging connection (2-1, 2-2) is the second charging connection (2-2).
