Abstract

The invention relates to a charging system (1) for charging an electrical energy storage device in an electric vehicle comprising: an input (2) for an alternating current, which is provided with a source of electrical energy (3), at least one transformer element (4) for transforming the alternating current into a direct current and a charge output (5) for connecting the charging system (1) to theelectric vehicle, wherein the charging system (1) is designed to connect the at least one transformer element (4) to the charge output (5) for charging the electrical energy storage device with directcurrent and wherein the charging system (1) is designed to connect the input (2) to the charge output (5) for charging the electrical energy storage device with alternating current.

Description

technical field [0001] The invention relates to a charging system for charging an electrical energy store of an electric vehicle. Furthermore, the invention relates to a method for charging an electrical energy store of an electric vehicle. Background technique [0002] Currently, there is interest in charging systems for charging electrical energy stores of electric vehicles. Such electric vehicles may be purely electric vehicles or hybrid vehicles. Various charging systems and charging methods are known from the prior art. For example, so-called direct current charging, also known as DC fast charging, can be carried out. In this case, the alternating current provided by the energy supply network is converted or rectified by means of at least one converter element. Furthermore, so-called alternating current charging or AC charging is known. [0003] In order to bill for the electrical energy supplied during DC charging, it is required by law to measure the supplied DC ...
