Fast charging application, charging in a few seconds and discharging in a few minutes. For example, electric tools, electric toys; In the UPS system, the super capacitor provides instantaneous power output as a supplement to the standby power supply of the engine or other uninterruptible systems; Applied to energy sources with sufficient energy and insufficient power, such as solar energy; Power support when the bus is switched from one power source to another; Low current, continuous discharge for a long time, such as backup power supply of computer memory. It is widely used in energy storage system, hybrid electric vehicle, rail transit, heavy machinery, wind power pitch, etc
