Product Introduction
Reduce costs and improve efficiency: Liquid-cooling thermal management reduces system auxiliary power consumption and simultaneously extends battery life; semi-integrated design—simple installation and easy debugging.
Flexible deployment: Using standardized containers allows for integrated transportation and lifting, with no geographical limitations. Pre-commissioning reduces on-site integration work, enabling rapid grid connection, simple installation, and easy commissioning.
Safe and reliable: Electrical components and batteries are housed separately to prevent the spread of thermal runaway; reliable disconnection within microseconds reduces short-circuit current by 75%; at the PACK level, fire suppression using perfluorohexanone is employed, coupled with combustible gas detection and ventilation systems; water-based fire suppression is available as an optional feature.
Intelligent Operations and Maintenance: Local EMS + cloud platform for online intelligent monitoring, enabling minimal staffing and digital operations & maintenance; self-diagnosis of faults, remote troubleshooting and upgrades;

SBMU
When the circuit current is detected to exceed the normal operating current, the relay’s holding voltage is cut off, triggering the relay’s trip action and disconnecting the main circuit. In the event of a large short-circuit current, since the fuse’s melting time is shorter than the relay’s trip response time, the primary function of disconnecting the main circuit is performed by the fuse.
