Abstract

A device for operating a charging unit that is connected/is connectable to a supply network and to a rechargeable energy store. A control unit and at least one sensor connected to the control unit are provided, the control unit being connected to a control input of the charging unit to switch on the charging unit as a function of a measured value of the at least one sensor for charging the energy store, or to switch it off for interrupting an electrical connection between the supply network and the energy store.

Claims

1. A device for operating a charging unit, comprising:

a control unit; and

at least one sensor connected to the control unit;

wherein the control unit is connectable to a control input of the charging unit, which is connectable to a supply network and to a rechargeable energy store, to switch on the charging unit as a function of a measured value of the at least one sensor for charging the energy store, or to switch it off for interrupting an electrical connection between the supply network and the energy store.

2. The device of claim 1, wherein the sensor is assignable to the supply network.

3. The device of claim 1, wherein the sensor includes a voltage sensor for detecting a supply voltage of the supply network.

4. The device of claim 1, wherein the sensor includes a temperature sensor.

5. The device of claim 1, wherein the control unit is connected to a timer.

6. The device of claim 1, wherein the control unit is connected to an actuator switch.

7. The device of claim 1, wherein the control unit is a separate control device.

8. The device of claim 1, wherein the control unit is integrate-able into the charging unit.

9. A charging system for electrically charging an energy store, comprising:

a supply network;

a charging unit connected to the supply network; and

a device for operating a charging unit, including a control unit and at least one sensor connected to the control unit, wherein the control unit is connectable to a control input of the charging unit, which is connectable to a supply network and to a rechargeable energy store, to switch on the charging unit as a function of a measured value of the at least one sensor for charging the energy store, or to switch it off for interrupting an electrical connection between the supply network and the energy store.

10. The charging system of claim 9, wherein at least one of the charging unit and the control unit includes at least one signaling device for signaling an operating state of the charging unit.
