BYD Energy Storage introduced its fourth-generation residential battery, the Battery-Box HVB, at the Smarter E Europe trade exhibition.
The new high-voltage Blade system has a capacity of up to 29.6 kWh per stack and a constant output of 25.6 kW.
Key features include modular capacity ranging from 5.9 kWh to 29.6 kWh per cabinet, high-power output, and the use of lithium-iron-phosphate Blade cells for enhanced safety and lifespan.
Analysts predict that modular home batteries like the HVB could capture 25 percent of the residential energy storage market by 2030, with BYD planning to start deliveries in China in Q3 2025 and expand to key European markets and Southeast Asia by year-end.
