Abstract

The invention provides a high-pressure system integrated control method and device and a pure electric automobile. The high-pressure system integrated control method is applied to a main controller. The main controller integrates the functions of a DC power supply circuit, an on-board charger circuit and an electric warm air system controller. The high-pressure system integrated control method comprises the steps that first control signals sent by an automobile controller are received, and the first functional categories of the first control signals are identified; and corresponding first instructions are generated according to the first functional categories of the first control signals, and operation is executed on corresponding equipment according to the first instructions. According to the technical scheme, a high-pressure system is simplified, and the number of parts is decreased, so that wiring between components is more concise, and the size of a whole circuit is decreased; the power consumption is reduced; the reliability of the high-pressure system is improved; and in addition, the first control signals are processed in a unified mode through the main controller, so that conflict interference between the signals is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an integrated control method and device for a high-voltage system and a pure electric vehicle. Background technique [0002] Such as figure 1 As shown, PEU (Power Electronics Unit, power electronic device) 100 integrates MCU (Microcontroller Unit, drive motor controller) 101, OBC (On-board Charger, on-board charger circuit) 102, PTC controller (electric heating system controller ) 103, DC / DC (direct current power supply circuit) 104 and VCU (Vehicle Control Unit, vehicle controller) 105 functions. Among them, the MCU and VCU in the PEU exchange information to control the motor through three-phase output; at the same time, it cooperates with the whole vehicle to implement high-voltage discharge (active discharge). [0003] DC / DC and OBC contain controllers inside. The PTC controller itself has control functions. It receives or sends control signals through high-voltage...
