SUPERCONDENSER APPLICATION
BIGCAP supercondenser is applied in scenarios that demand frequent rapid charge and discharge cycles, instead of long-term compact energy storage.
It is widely adopted in automobiles, buses, trains, cranes and elevators for regenerative braking, short-term energy storage and burst-mode power supply.
The compact version serves as power backup for static random-access memory (SRAM).
