Problems solved by technology
When balancing between batteries or supercapacitors, if non-energy-consuming equalization is selected, the energy will be transferred from the high-energy monomer to the low-energy monomer through the intermediate energy storage device, but when the high-energy monomer and the low-energy monomer When the pressure difference or energy difference between energy cells is small, it will greatly affect the speed of equilibrium
If the energy consumption balance is selected, the high-energy monomer is generally connected to the bypass shunt resistor, and the excess energy will be consumed through the heat of the power resistor, but this method will increase energy consumption

Description
technical field [0001] The present invention relates to the technical field of power supply equipment, in particular to a combined equalization device for a composite power supply, and also relates to an equalization method for the equalization device. Background technique [0002] Electric vehicles have the advantages of energy saving, environmental protection, and high energy utilization rate. Now that oil resources are increasingly scarce, the advantages of electric vehicles are becoming more and more obvious. At present, an important factor restricting the development of electric vehicles is their short driving range, and improving energy utilization efficiency is of great significance to electric vehicles. [0003] Most of the electric vehicles produced by manufacturers now use a single energy structure. During the driving process of electric vehicles, they will experience acceleration, starting and climbing. At this time, the instantaneous discharge current is very lar...
