By means of the active voltage balancing device, a part of electricity of the high-voltage energy storage devices is transmitted to the low-voltage energy storage devices, and the problems that an existing balance device is low in efficiency, severe in heating and low in speed, and drive circuits are not reliable are solved.
Description
technical field [0001] The invention relates to a voltage equalization device, in particular to an active voltage equalization device. Background technique [0002] At present, the widely used voltage equalization technology mainly uses high-power resistors as energy loss devices, and converts part of the electric energy of high-voltage energy storage devices into heat energy for loss through switch network control. Although this passive equalization technology has been maturely used, However, there are problems of low efficiency and serious heat generation when the balance current is large, and it is almost impossible to use it in some occasions that require high efficiency and heat dissipation. Significance. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide an active voltage equalization device, which can transfer part of the electric energy of the energy storage device with high voltage to the energy storage d...
