The low power super capacitor system comprises multiple super capacitors, multiple discharge loops, a voltage detection module and a controller. Monitoring and operation on work states of the super capacitors are carried out through the voltage detection module and the controller, so the discharge loops connected with the super capacitors are adjusted, and self-matching low power control on the series super capacitor sets is effectively realized, the low power super capacitor system having the self-matching function realizes low manufacturing cost, operation loss is small, the highest operation voltages of the super capacitors are consistent, service life of the system is long, and strong reliability is further realized.

Description

technical field [0001] The invention relates to a supercapacitor system, in particular to a low-power supercapacitor system with a self-matching function. Background technique [0002] A supercapacitor is a power supply with special properties between traditional capacitors and batteries, mainly relying on the electric double layer and redox pseudocapacitance. Charge stores electrical energy; however, no chemical reaction occurs during the energy storage process. This energy storage process is reversible, and because this supercapacitor can be repeatedly charged and discharged hundreds of thousands of times, its basic principle is the same as that of other types of double-electric Like multi-layer capacitors, the electric double layer structure composed of activated carbon porous electrodes and electrolytes is used to obtain super large capacity; it has technical characteristics such as high energy density, long service life, and wide operating temperature range. It is used ...

Problems solved by technology

If the voltage difference threshold of the supercapacitor is low, the discharge circuit will work for a long time, resulting in a waste of system energy and a reduction in device life; if the voltage difference threshold is high, the discharge circuit will basically fail and cannot complete the voltage balance task.

[0006] 2. Does not have self-adjustment function

If the factory parameters are always controlled, it may cause parameter mismatch and cause premature failure of power batteries such as supercapacitors
