Abstract

The invention relates to the technical field of storage batteries, in particular to a novel battery management system for an electric vehicle, including an external power access module, a controllableswitch, a voltage acquisition module, a current acquisition module, a temperature management system, a plurality of sub-energy storage platforms and an MCU, wherein the plurality of sub-energy storage platforms are connected in series to each other to form an energy storage platform; the voltage acquisition module collects the voltage at two ends of the energy storage platform and is connected with the MCU; the current acquisition module collects the current flowing through the energy storage platform and is connected with the MCU; and the temperature management system regulates the temperature of the energy storage platform. The novel battery management system for an electric vehicle has the advantages that the sub-energy storage platforms are arranged to constitute an energy storage platform of the battery, so that the battery can be conveniently expanded or modified into a battery pack of other voltages, the charging voltage of the battery core is monitored and balanced by a balancing module and a sampling module, to prolong the service life of the battery core, and the safety management unit is used for cutting off the power supply in an emergency, thereby avoiding or reducingthe occurrence of secondary accidents.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a new battery management system for electric vehicles. Background technique [0002] With the development of society, lithium batteries are widely used in various fields of production and life. The application and management of lithium batteries have become a very critical technology in the development of various equipment. Since the beginning of this century, great breakthroughs have been made in the production and research of lithium batteries, because of their many good advantages, such as stable discharge voltage, low self-discharge rate, wide operating temperature range, no memory effect, long storage life, and light weight. , small size and other characteristics, it has gradually replaced the traditional nickel-cadmium battery and lead-acid battery, and has become the current mainstream power battery in the application fields of social production and life. Becaus...
