company news about Energy storage fuses are mainly used in three places

1) Battery module

2) Battery cluster/battery pack

3) AC-DC conversion inverter.

In terms of quantity, energy storage fuses are used more than photovoltaics, wind power, and electric vehicles. Each 1GW energy storage system uses about 6,000-10,000 main fuses and 30,000-50,000 internal fuses. Wind power and photovoltaics are mainly used in confluence, inverter, and control systems, while each battery module and battery cluster in the energy storage battery part needs fuse protection, and the number of uses is more.

From the perspective of voltage level, the voltage platform of wind, wind and storage is higher than that of electric vehicles. Energy storage requires 1000V and 1500V platforms, while most electric vehicle voltage platforms are 500V and 800V. 1000V is upgraded to 1500V, the capacity is increased, and the requirements for breaking capacity are increased. The energy storage system has high power, high voltage, low power supply internal resistance, and generally high short-circuit current amplitude, which puts higher requirements on the breaking capacity of the fuse.

Compared with photovoltaic and wind power, the electrochemical energy storage market developed relatively late, and China Melting is at the same starting line as foreign-funded enterprises. In the field of energy storage, due to the late development of the electrochemical energy storage market, China Melting has taken the lead in the domestic market by virtue of its rapid market tracking and timely product research and development capabilities. Customers include CATL, Sungrow, etc.
