Charging control method, central control unit (CCU), vehicle and computing device

Abstract

The invention provides a charging control method, a central control unit (CCU), a vehicle and a computing device. The charging control method is applied to the central control unit (CCU), and the central control unit (CCU) is used for being connected to a charging port of the vehicle. The method comprises the following steps: a connection confirmation (CC) signal on a circuit connected to the charging port is acquired; according to the connection confirmation (CC) signal, a charging plug head type connected to the charging port is determined, and the charging plug head type can be a fast charging plug head, a slow charging plug head, a vehicle-to-vehicle charging plug head or an external power supply charging plug head; and according to the charging plug head type, the vehicle is controlled to get into an operating mode corresponding to the charging plug head type. According to the embodiments of the invention, the connection confirmation (CC) signal on the circuit connected to the charging port is acquired by the central control unit (CCU), moreover, a charging plug head type is determined according to the signal, the vehicle is then controlled to get into a corresponding operating mode, the control and guiding functions of different parts are integrated, the material cost is reduced, and the future charging development trend is met.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a charging control method, a main control unit CCU, a vehicle and a computing device. Background technique [0002] In view of the development trend of diversification of vehicle charging methods, the requirements for charging guidance control functions are gradually increasing. At present, the functions related to vehicle charging control are scattered and distributed on multiple components, such as CMU (Cell Monitoring Unit, Cell Monitoring Unit) for electronic locks. For control, OBC (on board charger) guides control of slow charge CC, CP and vehicle inverter output guide control, BMS (battery management system, BATTERY MANAGEMENT SYSTEM) guides control of fast charge, VCU (vehicle control Device, Vehicle control unit) to control the indicator light of the charging port, etc., resulting in complex vehicle control interaction, low level of functional integration, and cannot meet the ...

[0002] In view of the development trend of diversification of vehicle charging methods, the requirements for charging guidance control functions are gradually increasing. At present, the functions related to vehicle charging control are scattered and distributed on multiple components, such as CMU (Cell Monitoring Unit, Cell Monitoring Unit) for electronic locks. For control, OBC (on board charger) guides control of slow charge CC, CP and vehicle inverter output guide control, BMS (battery management system, BATTERY MANAGEMENT SYSTEM) guides control of fast charge, VCU (vehicle control device, Vehicle control unit) to control the indicator light of the charging port, etc., resulting in complex vehicle control interaction, low level of function integration, and unable to meet future functional development needs

[0003] At present, pure electric vehicles use two charging ports, namely AC slow charging port and DC fast charging port, which makes the control interaction more complicated, and there may be the possibility of inserting two charging guns at the same time, without protective measures
