Embodiment Construction

[0026] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary, and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as a limitation to the technical solution of the present invention.

[0027] like figure 1 and figure 2 As shown, the present invention provides a charging and power-on control method based on pure electric vehicles, including the following steps:

[0028] Step 1. It is necessary to manually insert an external charging gun or other charging device into the vehicle for operation. After the charging gun or other charging device is connected to the socket of the vehicle charger, the charger receives high-voltage AC power from the outside connected to the vehicle. The charger will send a charging wake-up signal to the vehicle controller. In this application, the charging wake-up signal is a high level of 12V. ...

Abstract

The invention relates to a charging power-on control method based on a battery electric vehicle. The method comprises the following steps that after receiving an externally-connected high-voltage alternating current, a charger sends a charging awakening signal to a vehicle control unit; the vehicle control unit sends remote frame messages to high-voltage components of a vehicle CAN (Controller Area Network) communication network by virtue of a vehicle network and requests each high-voltage component to supply a feedback signal of whether a severe fault exists; if the feedback signal refers to no fault, the electric quantity of a battery pack is determined to be not full; the charger judges whether a main negative relay and a main positive relay are sucked or not; the vehicle control unit controls the main negative relay and the main positive relay to perform charging control. Charging power-on process time sequence planning is performed on an electric vehicle structure state based on the scheme, so that the whole vehicle can perform a normal operation process.

Description

technical field [0001] The invention belongs to the field of new energy vehicle control systems, and specifically refers to a charging and power-on control method based on pure electric vehicles. Background technique [0002] The development direction of new energy vehicles, as people continue to pay attention to energy security, the development of new energy vehicles has also become the focus of people's increasing attention. In the future, electric vehicles will become the key direction of automotive technology development. The two common working conditions of pure electric vehicles are the driving process, that is, the discharge process of the vehicle battery pack, and the other process is the charging process. [0003] In the prior art, the charging control of the pure electric vehicle platform is mostly realized by software. When the electrical topology of the vehicle is different, the control method of the software will be different. Since the charging process of the ...
