Use of two DC/DC controllers in the power electronics system of a charging station or electricity charging station

1. A charging station for an electricity charging station, comprising:

a rectifier for connection of the charging station to a public low-voltage network;

a first DC voltage converter connected to the rectifier, the first DC voltage converter being a DC/DC converter,

a first DC chopper connected to the first DC voltage converter;

a battery connected to the first DC chopper, the battery configured to store power received via the first DC voltage converter and the first DC chopper;

a second DC chopper connected to the first DC voltage converter for connection of an electric automobile to the charging station; and

a housing,

wherein the first DC voltage converter, the first DC chopper, the battery, and the second DC chopper are all accommodated in the housing,

wherein the first DC voltage converter is connected between the rectifier and each of the first DC chopper and the second DC chopper to provide power received from the rectifier to the first DC chopper and the second DC chopper.

2. The charging station as claimed in claim 1 , further comprising:

an EMC filter connected downstream of the second DC chopper.

3. The charging station as claimed in claim 2 , further comprising:

a second DC voltage converter connected downstream of the EMC filter and configured for a discontinuous conduction mode.

4. An electricity charging station, comprising:

a charging station as claimed in claim 3 .

5. The electricity charging station as claimed in claim 4 , wherein:

the battery comprises a plurality of strings.
