Embodiment Construction

[0022] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0023] see figure 1 , the present invention discloses an AC power supply in an electric vehicle. The AC power supply in the electric vehicle includes a power battery 10, a power distribution box 20 (PDU), a vehicle charger 30 and a vehicle charging socket 40, and the power battery 10 passes through The power distribution box (PDU) 20 is connected to the DC interface of the vehicle charger 30 , and the AC interface of the vehicle charger 30 is connected to the vehicle charging socket 40 . Therefore, the DC power of the power battery 10 is converted into 220V AC output by the on-board charger 30 for use by AC equipment. In the AC power supply system, the power battery 10, the power distribution box 20 and the on-board charger 30 are all exi...

Abstract

The invention discloses an alternating current power supply used in an electric vehicle. The alternating current power supply comprises a power battery, a power supply distribution box, a vehicle-mounted charger and a vehicle-mounted charging socket, wherein the power battery is connected to the direct current interface of the vehicle-mounted charger through the power supply distribution box; and the alternating current interface of the vehicle-mounted charger is connected to the vehicle-mounted charging socket. The alternating current power supply used in the electric vehicle is simple in structure, low in cost and quite high in output power.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an AC power supply in the electric vehicle. Background technique [0002] The electric vehicle uses the power battery as the power supply of the vehicle. Therefore, the power supply system in the vehicle is a DC power supply. If you want to use an external AC device in the electric vehicle, you must use a DC-to-AC device to convert the DC to the corresponding voltage. alternating current. In the Chinese patent with the publication number CN201210593270A, a "system for external power supply of electric vehicles" is disclosed, which describes that the electric vehicle power battery converts DC high voltage into AC power by adding a bidirectional DC / DC module and a bidirectional DC / AC module output system. At present, the 220V AC power supply used in traditional cars or electric vehicles on the market is to convert the 12V DC power in the vehicle cigarette lighter into 220V AC pow...
