Abstract

The invention discloses a control method, device, equipment and automobile of an integrated vehicle-mounted charger. The control method of the integrated vehicle-mounted charger includes: acquiring a wake-up signal of an integrated controller; after the integrated controller receives the wake-up signal, Control the integrated on-board charger to initialize; after the initialization is completed, select the working mode of the integrated controller according to the connection status of the charging gun, the wake-up state of the integrated on-board charger, and the control instructions of the vehicle controller VCU or battery management system BMS ; Control the integrated on-board charger to supply power to the power battery and storage battery of the vehicle according to the working mode. In the embodiment of the present invention, by controlling the working mode of the integrated on-board charger, the functions of high-voltage DC charging and low-voltage DC voltage conversion are realized, and the output power of the DC converter is limited when the on-board charger and the DC converter work at the same time , leading to the low-voltage auxiliary battery problem of electric vehicles.

Description

technical field [0001] The invention relates to the field of control of an integrated on-board charger, in particular to a control method, device, equipment and automobile of an integrated on-board charger. Background technique [0002] The integrated design of the on-board charger motor and the DC converter provides a clear solution for the reliability, high efficiency, miniaturization and cost performance of electric vehicles. Since the on-board charger and the DC converter share the control board, the on-board charger and the DC When the converters work at the same time, the output power of the DC converter is limited by the on-board charger, and the efficiency of charging the low-voltage auxiliary battery of the electric vehicle is low, resulting in low power of the low-voltage battery. Therefore, the traditional on-board charging and DC conversion are controlled separately. Method is no longer available for this scenario. Contents of the invention [0003] In order t...
