BYD introduced the Haohan integrated energy storage platform with a rated capacity of 14.568 MWh At SNEC 2026
The company stated that the system uses 2,710 Ah cells and integrates battery storage with energy management
The liquid-cooled system features an IP66-rated enclosure and LFP battery chemistry for utility-scale applications
BYD, a leading battery storage manufacturer, showcased its integrated energy storage platform, Haohan, at SNEC 2026. Designed for utility-scale applications, the solution combines battery storage with energy management functions in a single platform.
BYD claims that the Haohan platform with its 14.568 MWh of storage capacity is the world's largest integrated BESS.
The overall architecture integrates the battery energy storage system (BESS) with energy management capabilities, while its EMS unit combines the power conversion system (PCS) and medium-voltage transformer. BYD shared that the PCS has been developed in-house and achieves a conversion efficiency of 98.3%. The system uses 2,710 Ah battery cells, compared with around 500 Ah in many commercially available systems.
For the Haohan platform, BYD uses lithium iron phosphate (LFP) battery chemistry and features an IP66-rated enclosure with liquid cooling. It is designed to operate in ambient temperatures ranging from −30°C to +55°C and at altitudes of up to 3,000 m, with reduced performance under more demanding operating conditions.
According to the company, the Haohan integrated solution is available for global markets and has already been deployed in select projects. The company expects commercial deliveries to begin next month.
