Abstract

The invention relates to a power control power supply system for an electric vehicle. The power control power supply system comprises a storage battery, a first power supply circuit and a second power supply circuit, wherein the storage battery supplies power to a single-chip microcomputer minimum system circuit, a DI/DO unit circuit and a CAN (controller area network) communication interface circuit of a VCU (vehicle control unit) module through the first power supply circuit and supplies power to an AI/AO unit circuit of the VCU module, a motor controller module, a relay unit of the VCU module and a contactor set of a high voltage distribution module through the second power supply circuit only when a switch of the electric vehicle is turned off. According to the power control power supply system for the electric vehicle, an ordinary power supply mode and a non-ordinary power supply mode are provided for a PCU (power control unit) by a first power supply circuit and a second power supply circuit, and when the switch of the electric vehicle is turned off, only part of circuits required to work during standby of the VCU module are supplied with power, so that the electric vehicle is awoken, stand-by power consumption is reduced to the greatest extent, the problem about long-time storage of the electric vehicle is solved, the system is very convenient to use by a user, the rigid index of the electric vehicle is improved, and the power control power supply system is green and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a power control power supply system for electric vehicles. Background technique [0002] At present, new energy vehicle technology is gradually shifting from the laboratory to the stage of productization. Energy saving, miniaturization, economy, and light weight have become the development direction of the industry. As its core component, the power control system (PCU) has higher requirements for its performance parameters. , where the indicator of power consumption is one of them. [0003] The power control system (PCU) is the core component system of the electric vehicle, which is responsible for multiple functions such as control, calculation, signal conversion processing, fault diagnosis, communication and driving. Carry out reasonable power distribution and coordinate the energy flow among various components to improve the power, safety and efficiency of the vehic...
