Charger and charging method
First Claim
1. A charger configured to charge at least one energy storage device to be charged by means of an electrical charging power provided by an electrical power supply grid, the charger comprising:
- a grid parameter detector unit configured to detect at least one electrical grid parameter of the electrical power supply grid and for outputting a grid parameter detection signal on the basis of the at least one detected electrical grid parameter;
a control unit configured to receive the grid parameter detection signal and to determine a control signal on the basis of the received grid parameter detection signal; and
a charging power adjustment unit configured to receive the control signal and being configured to adjust the electrical charging power on the basis of the control signal, wherein the electrical charging power is increased from a first electrical charging power value to a second electrical charging power value when the at least one electrical grid parameter is above a first threshold value and below a second threshold value larger than the first threshold value.

Abstract
A charger adapted for charging at least one energy storage device to be charged by means of an electrical charging power provided by an electrical power supply grid is provided. The charger includes a grid parameter detector unit adapted for detecting at least one electrical grid parameter of the electrical power supply grid and for outputting a grid parameter detection signal on the basis of the at least one detected electrical grid parameter. A control unit receives the grid parameter detection signal and determines a control signal, wherein a charging power adjustment unit adjusts the electrical charging power on the basis of the control signal.
