Problems solved by technology

[0002] Usually, when the electric energy of the power battery is about to run out, the AC power of the power grid can be converted into DC power by the on-board charger to charge the power battery to meet the requirements of the driving range of the vehicle. However, this can only realize the energy from the power grid to the power Battery transmission, the function is relatively simple, needs to be improved

Embodiment Construction

[0037] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

[0038] In order to enrich the functions of the on-board charger, not only can the energy transfer from the power grid to the power battery be realized, but also the energy of the power battery can be transferred out to meet the external power supply requirements of the power battery such as vehicle-to-vehicle or external loads. The charger with charging and discharging function can not only charge the power battery, but also realize the function of the power battery supplying power for ex...

Abstract

The invention discloses a vehicle-mounted charger, a control method and device thereof and a vehicle. The control method of the vehicle-mounted charger comprises the steps that a connection determining signal of the vehicle-mounted charger is collected; the connection mode of the vehicle-mounted charger is determined according to the connection determining signal; and charging and discharging control over the vehicle-mounted charger is conducted according to the connection mode of the vehicle-mounted charger. The vehicle-mounted charger can conduct charging and discharging in more modes and isricher in function.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a control method of a vehicle-mounted charger, a control device of the vehicle-mounted charger, the vehicle-mounted charger and a vehicle. Background technique [0002] Usually, when the power of the power battery is about to be exhausted, the AC power of the power grid can be converted into DC power to charge the power battery through the on-board charger, so as to meet the requirements of the driving range of the vehicle, but this can only realize the energy from the power grid to the power. The transmission of the battery has a relatively simple function and needs to be improved. SUMMARY 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] Therefore, the present invention needs to provide a method for controlling the vehicle-mounted charger, which can realize the ch...
