Abstract

The invention relates to a power supply control system of an electric automobile. The system comprises a CAN transceiver, an MCU control chip, a monitoring interface and a power supply control circuit; the power supply control circuit comprises a storage battery, a first power supply source and a second power supply source; the first power supply source is used for converting the voltage of a storage battery into working voltage of the MCU control chip, the monitoring interface and the CAN transceiver to be outputted; when the electric automobile is off, the MCU control chip is awakened through external signals received by the monitoring interface and the CAN transceiver; the second power supply source is used for converting the voltage of the storage battery into working voltage to be outputted to a peripheral electrode when the MCU control chip is awakened. According to the power supply control system of the electric automobile, the first power supply source supplies power to some circuit when the automobile is in an off state, and the second power supply source supplies power to other circuits under the awakening state, so that the normal use of the electric automobile can be ensured, and the power consumption of the electric automobile under a non-working state can be greatly decreased.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, and more specifically, relates to a power supply control system for electric vehicles. Background technique [0002] At present, most electric vehicles in China adopt the method of supplying power to the control circuit for a long time. The control unit of the whole vehicle and the surrounding circuits are always in the working state, so that the batteries that supply power to these circuits are always in a state of energy consumption. On the other hand, supplying power to each electronic component for a long time will also have an impact on performance wear and service life of the electronic component. [0003] New energy vehicle technology has gradually shifted 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 high...
