In the case of centralized operation of lifting machinery, the engine is in an overload state, which will lead to a decrease in speed and voltage, and sufficient instantaneous power is required for a short time. With high power density, supercapacitors can quickly provide high current to make up for the lack of power in the system and avoid the risk of downtime caused by voltage and frequency fluctuations

In the process of braking or heavy load downward of the crane or elevator, the energy fed back by the system is collected, and the collected energy is released when the crane or elevator is working. In this way, the purpose of energy conservation and environmental protection is achieved.

From the intrinsic safety mechanism, it ensures the normal operation of the lighting power supply system at low temperature, and that there will be no risk of fire and explosion.

Supercapacitors are used in the electric start system of internal combustion engines together with batteries, which can effectively protect the batteries, prolong the cycle of the batteries, and reduce the required capacity.

Maintain the high-current discharge characteristics at above -40°C to ensure the normal power supply for the equipment starting system;
