Safety

Our self-developed liquid cooling system effectively dissipates heat when battery temperature is high, physically reducing the probability of thermal failure, and keeping the temperature difference between cells within 2.5°C. The PCS comes with a built-in arc detection system + intelligent algorithms, cutting off the main circuit in seconds upon arc detection, ensuring the safety of electrical equipment. • The EMS, based on cloud architecture, conducts historical data trend analysis + machine learning to maintain the health of the cells throughout their lifecycle. A three-level fire safety design: the 1st level provides early warning with an embedded thermal runaway warning module that provides a 10-minute advanced warning, giving firefighters more valuable time. The 2nd level can achieve active firefighting at the single Pack level. When a single Pack has thermal runaway, it can perform intelligent directional spot spraying at the Pack level. The 3rd level, system-level fire protection barrier of the Z BOX, ensures that other outdoor cabinets can continue to operate safely.

Stability

Our self-developed SmartM200 system supports millisecond-level response and can realize intelligent detection, intelligent analysis, centralized management, and centralized control of the energy storage system. The PCS has a Virtual Synchronous Generator (VSG) function, possesses rotational inertia characteristics, and can perform primary frequency regulation and secondary frequency regulation. The PCS has the ability to perform black-start operations, has real-time load-following capabilities, and active SVG dynamic reactive power support capability. The EMS has edge computing capabilities, allowing for decision-making, intelligent analysis, and unmanned operations at energy storage stations. Additionally, 5G / Ethernet enables high-speed connectivity between local and cloud data, improving grid / EaaS dispatch response capabilities.

Economy

Over 15 years of ultra-long design life, the intelligent cell temperature control mechanism extends cell life by 25% and extends system usage life by 18%. The full lifecycle return rate is increased by 22%, and LCOS is reduced by 17%.

Efficiency

The advanced ANPC three-level technology, optimized multistage SVPWM control technology, low-loss magnetic component design technology, can achieve a maximum efficiency of 99.2%. The liquid cooling system can heat the batteries in the cold northern regions, can control the cell temperature within the optimal range of 25°C ~35°C, achieving optimal power and capacity, 95% DOD, and system efficiency can be over 95%.
