Abstract

The invention discloses a balancing device and method for energy transfer in a supercapacitor module, and relates to the field of supercapacitors, the device comprises a supercapacitor module, an MCU module and energy transfer circuits, the supercapacitor module comprises a plurality of supercapacitor monomers, and one supercapacitor monomer corresponds to one energy transfer circuit; the MCU module is used for collecting the monomer voltage of each supercapacitor monomer in the supercapacitor module, outputting a control signal to control the corresponding energy transfer circuit to be conducted and charging the supercapacitor monomer by using When the supercapacitor module is charged, a control signal is output to control the conducting of a corresponding energy transfer circuit, and the energy released by the supercapacitor module is used for charging the supercapacitor monomer through the energy transfer circuit. The energy released by the supercapacitor module charges the supercapacitor monomer, so that the problem that the energy consumption in the supercapacitor module is relatively large due to the fact that the supercapacitor monomer with overhigh voltage is subjected to active or passive discharge for monomer equalization in the prior art is solved.

Description

technical field [0001] The invention relates to the field of supercapacitors, in particular to a device and method for equalizing energy transfer in a supercapacitor module. Background technique [0002] Supercapacitor refers to a new type of energy storage device between traditional capacitors and rechargeable batteries. It not only has the characteristics of fast charging and discharging of capacitors, but also has the energy storage characteristics of batteries. Compared with batteries and traditional physical capacitors, supercapacitors have the characteristics of high power density, long cycle life, wide operating temperature limit, maintenance-free, green and environmental protection, so their applications are becoming more and more extensive. In the fields of auxiliary peak power, backup power supply, storage of regenerative energy, and alternative power supply, supercapacitors are considered to be one of the most promising energy storage methods due to their excellen...
