The invention relates to a system for charging an electrical energy store (110) of a vehicle (100). The system comprises a vehicle-side plug (120) having first contacts (122, 123, 124) and second contacts (126), wherein the first contacts (123, 124) are coupled to the electrical energy store (110) of the vehicle (100) by means of a first controllable voltage transformer (130) in order to form a first current path (SP1), and wherein the second contacts (126) can be coupled to the electrical energy store (110) of the vehicle (100) in order to form a second current path (SP2). Furthermore, the system comprises a charging device (200), which is coupled to an energy supply network and which comprises a first coupling (221) having third contacts (222, 223, 224), which first coupling can be connected to the first contacts (122, 123, 124) of the plug (120) in order to charge the electrical energy store (110) of the vehicle by means of alternating current via the first current path (SP1), and a second coupling (225) having fourth contacts (226), which second coupling can be connected to the second contacts (126) of the plug (120) in order to charge the electrical energy store (110) of the vehicle by means of direct current via the second current path (SP2) and is coupled to the energy supply network by means of a second controllable voltage transformer (240). The first and the second couplings (221, 225) of the charging device (200) are designed as a common coupling (210), and therefore, when the common coupling (210) is connected to the plug (120), the first contacts (122, 123, 124) of the plug (120) are connected to the third contacts (222, 223, 224) of the first coupling (221) in an electrically conductive manner and the second contacts (126) of the plug (120) are connected to the fourth contacts (226) of the second coupling (225) in an electrically conductive manner, whereby a current flow is simultaneously enabled via the first and the second current paths (SP1, SP2) in order to charge the electrical energy store (110). |
