The invention discloses a vehicle-mounted charging device of an electric vehicle and an electric vehicle. The vehicle-mounted charging device includes a bidirectional AC / DC converter, a bidirectional DC / DC converter and a control module; the control module includes a first controller, a second controller and a third controller; the first controller is connected with the bidirectional AC / DC converter; the second controller is connected with the bidirectional DC / DC converter; the third controller communicates with the first controller and the second controller; and the third controller controls the bidirectional AC / DC converter through the first controller and controls the bidirectional DC / DC converter through the second controller according to received mode instructions, and therefore, when the vehicle-mounted charging device is in a charging mode, a power battery is charged through an alternating-current power source, or when the vehicle-mounted charging device is in an inversion mode, power is supplied for an alternating-current load through the power battery. With the vehicle-mounted charging device of the invention adopted, full-digital control can be realized, a control circuit is more simplified, and the flexibility, universality and intelligence improve of a system are improved, and the realization and expansion of platformization can be facilitated.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle-mounted charging device for an electric vehicle and an electric vehicle with the vehicle-mounted charging device. Background technique [0002] In recent years, with the continuous advancement of electric vehicle technology, the electric vehicle market has gradually developed, and as an important part of electric vehicles - on-board charging devices have also made great progress. However, in the related art, when controlling the on-board charging device, the control circuit is relatively complicated, the system has poor flexibility and low versatility, which is not conducive to the platformization of the on-board charging device. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, an object of the present invention is to propose a vehi...
