Following the footsteps of the national “double carbon” goal, we focus on providing stable and reliable semiconductor device solutions for the energy storage industry to meet our customers’ unremitting pursuit of performance.

Backup Power Systems When the original power supply system equipment fails, the system occurs command through the relay protection device for safe switching, the energy storage system to the load for emergency power supply, at this time the energy storage system is a backup power supply. In order to ensure the normal operation of the equipment, the power switching needs to be seamless, and EXPSEMI can provide solutions to prevent the current shock generated at the moment of power cut-in from affecting the use of the equipment. Energy Conversion Systems In the energy storage system, the energy conversion system is the key to realize the two-way conversion of electric energy, mainly responsible for the conversion of electric energy, voltage and frequency adjustment, power control, etc. It not only realizes the efficient conversion of electric energy, but also ensures the good interaction between the energy storage equipment and the power grid, EXPSEMI provides customers with the solution, and provides the system with stable and reliable service when the power grid needs electric energy.

Battery Management Systems In an energy storage system, the battery management system mainly plays a sensing role, and its core responsibility is to detect, evaluate, protect and equalize the battery. It can intelligently manage and maintain each battery cell. The MOSFET products developed by EXPSEMI can effectively control the system current to avoid overcharging and overdischarging of the battery, thus extending the service life of the battery. Energy Storage Inverters Power is stored in the energy storage system, and the power in the storage device can be used when the grid is blackout or unstable, in which case it is necessary to turn the DC power supply into AC power supply. The semiconductor device products developed by EXPSEMI can realize the fast switching of this process as well as the circuit renewal to ensure the stable operation of the system.
