Abstract

The invention provides an electric vehicle single battery power balance circuit, device and method, wherein, the Electric vehicle single battery power balance circuit, device and method comprises a plurality of battery connection terminals, and each adjacent two battery connection terminals are connected with a electric quantity equalization module, and the electric quantity equalization module comprises two diodes in reverse parallel, and the diodes are of the same type.- The invention discloses an electric quantity balancing circuit, a device and a method of an electric vehicle single battery, which are low in cost, high in control efficiency, fast in speed and simple in structure, can be adapted to the battery system of most electric vehicles, and improves the service life and the energy utilization rate of the battery.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a circuit, device and method for electric vehicle battery power equalization. Background technique [0002] At present, the balance of power of electric vehicle battery packs at home and abroad is based on the series connection, and each series circuit of the battery pack is balanced separately. The equalization circuit is complex and has many components. [0003] For battery power balance of foreign pure electric vehicles, the design of active equalization function is often used to move the excess power to the battery with a lower single power. When equalizing each string of circuits of the battery pack, there are many equalizing components and complex structures. However, passive equalization design is widely used in China, which will dissipate more than electricity as heat. When equalizing each string of circuits in the battery pack, the power loss is serious, wh...
