Embodiment Construction

[0065] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0066] like figure 1 Shown is a working flow chart of a charging control method for an electric vehicle vehicle controller according to the present invention, including:

[0067] Step S101, receiving a to-be-charged status message sent by an on-board charger, the on-board charger is directly connected to a power battery system of an electric vehicle;

[0068] Step S102, prohibiting the motor from running, and controlling the vehicle to park;

[0069] Step S103, when receiving the completion of parking of the vehicle, issue a self-check command to the high-voltage components of the vehicle;

[0070] Step S104, if all the high-voltage components of the vehicle are self-tested normally, obtain charging parameters from the battery management system, send the charging parameters to the on-board charger, and control the on-board charger to ...

Abstract

The invention discloses a charging control method for a vehicle control unit of an electric vehicle and the vehicle control unit, and the method comprises the steps: receiving a to-be-charged state message sent by a vehicle-mounted charger, and enabling the vehicle-mounted charger to be directly connected with a power battery system of the electric vehicle; the motor is prohibited from running, and the vehicle is controlled to park; when the parking of the vehicle is completed, a self-checking command is sent to a high-voltage part of the vehicle; if all the high-voltage components of the vehicle are self-checked normally, charging parameters are obtained from the battery management system, the charging parameters are sent to the vehicle-mounted charger, and the vehicle-mounted charger is controlled to start charging the power battery system; and in response to the charging stop event, controlling the vehicle-mounted charger to stop charging the power battery system. A charging system architecture of a power battery system (PACK) without an alternating current relay is redesigned, a vehicle control unit (VCU) serves as a host, other multiple controllers serve as slaves, the VCU is controlled in the charging process, and tight communication, joint debugging and actions are achieved.

Description

technical field [0001] The invention relates to the related technical field of electric vehicles, in particular to a charging control method and a complete vehicle controller of a complete vehicle controller of an electric vehicle. Background technique [0002] Electric vehicles use a battery pack (PACK) to power the drive motor. The battery pack is AC charged by an on-board charger (On-Board Charger, OBC). In existing AC-chargeable electric vehicles, AC relays are commonly found in battery packs. The on-off of the battery pack and the on-board charger is controlled by the AC relay. [0003] However, if an AC relay is set, there will be the following problems: [0004] 1. During the AC charging process, the AC relay is controlled by the Battery Management System (BMS), which controls the closing and opening of the AC relay, and judges whether the AC relay is actually closed or not. The process is cumbersome and time-consuming. [0005] 2. The cost of the AC relay is high...
