The invention relates to an electric automobile power battery safety monitoring system and a low-voltage power distribution scheme thereof. The electric automobile power battery safety monitoring system comprises a storage battery, a power battery pack, a battery management system control unit, a vehicle control unit, a car frame system monitoring unit, a backstage remote monitoring terminal, a heating sheet and a DCDC. The battery management system control unit is serially connected with the storage battery through a relay S3, the battery management system control unit is used for monitoringthe power battery pack in real time online in a full life circle, and the data is uploaded to the backstage remote monitoring terminal by the vehicle control unit and the car frame system monitoring unit, so that normal operation of the vehicle is guaranteed, and the service life of the power battery is prolonged. When a hand switch of the whole car is switched off, the battery management system control unit further can be used for supplying power for the vehicle control unit and the car frame system monitoring unit by controlling the DCDC, timely early warning and fault analysis treatment arerealized, and the safety of the vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, and more specifically refers to a low-voltage power distribution method for a power battery safety monitoring system of an electric vehicle. Background technique [0002] With the development of the global economy and the increasingly prominent issues of energy and environmental protection, the automobile industry is transforming into an energy-saving green automobile industry. Electric vehicles have become one of the main directions for the development of energy-saving and environmentally friendly vehicles with the advantages of zero emissions and low noise. The popularization of electric vehicles has led to an increase in the number of electric vehicles in the world. As a key power part of electric vehicles, the importance of power batteries is self-evident. Vehicle safety, especially the safety of power batteries is still one of the important factors restricting its development, so...
