BYD Energy Storage launches Chess Plus for C&I energy storage in China

BYD Energy Storage, a provider of renewable energy solutions, and a business division of BYD Company Limited, has unveiled Chess Plus, its next-gen commercial and industrial (C&I) energy storage system designed to address challenges in safety, efficiency, and profitability.

Chess Plus establishes a new paradigm in energy storage through its cell-to-system (CTS) protection framework. At the core are 'thick blade battery' cells with ceramic terminals, eliminating leakage risks while enhancing corrosion resistance. These cells have passed extreme stress tests including 260% overcharge thresholds and thermal runaway simulations (–25~55℃).

Chess Plus has 2-hour fire-resistant battery casing and built-in aerosol fire suppression system. The thermal anomalies can be detected in advance due to the system-level protection including 8.0-magnitude seismic resistance, IP55 enclosures with sloping roofs for water drainage, and AI-driven risk prediction algorithms.

Featuring ultra-long life battery cells supporting over 10,000 cycles, Chess Plus ensures durability for steady operations. Its dual-mode cooling system — liquid cooling for batteries and smart forced air cooling for electronic equipment — reduces auxiliary power consumption by 20% while enhancing thermal consistency. This design extends component lifespan by 30%.

Chess Plus integrates high-performance edge computing for real-time SOC optimization and fault prediction. The system’s modular architecture allows independent data and control channels for stable operation.

Chess Plus is an energy storage solution for many application scenarios in industrial parks, EV charging hubs and microgrids. With AI-driven management, it is an ideal option for optimizing energy use and maximizing ROI across diverse settings.
