A circuit arrangement (200b) for charging an energy storage cell (291) of an electrical energy store is described. The circuit arrangement has (a) an electrical energy source (210), (b) a first electrical half-bridge circuit, which is coupled to the electrical energy source, (c) a first charge pump (231), which is associated with the first electrical half-bridge circuit, (d) a second electrical half-bridge circuit, which is coupled to the energy source, (e) a second charge pump (236), which is associated with the second electrical half-bridge circuit, (f) a first charging connection (271) for connecting a first connection contact of a first energy storage cell (291), wherein the first charging connection is coupled to a negative output of the second charge pump, (g) a second charging connection (272) for connecting a second connection contact of the first energy storage cell, wherein the second charging connection is coupled to a positive output of the first charge pump, and (h) a switching device (S1, S2, S3, S4), which is configured as a dual half-bridge circuit so as to allow the first charge pump to operate out of phase with the second charge pump. In addition, a method for charging an energy storage cell by using such a circuit arrangement and also a control device for actuating such a circuit arrangement are described. |
