Efficient, Powerful, and Energy Smart
High Energy Density with Faster, Precision Cooling
The Pion Power Liquid Cooling BESS features a tightly integrated structure that delivers exceptional energy density while maintaining consistent thermal balance. Its efficient liquid cooling system provides faster heat dissipation, keeping the cell temperature differential within ≤5°C. This reduces energy loss and supports stable, high-rate charge and discharge performance
Smart Battery Management
Pion Power Liquid Cooling BESS conducts real-time monitoring and use passive balancing of each battery cluster to minimize internal resistance and voltage deviation. This ensures consistent performance across modules, enhances overall energy efficiency, and extends the operational lifespan of the battery system
Multi-Protocol Integration for Seamless Communication
The system natively supports Modbus, TCP, MQTT, and DL/T645 protocols, enabling direct integration with EMS, SCADA, and smart grid platforms, without requiring external protocol converters or middleware. This significantly shortens deployment time, reduces system complexity, and ensures stable, low-latency data transmission.
Flexible & Scalable
Each cabinet is equipped with a built-in EMS. When connected in parallel (up to 10 units), the system automatically selects one cabinet as the master, while the others operate as slave units. Designed for 1000V DC systems, this setup allows seamless capacity expansion as your energy needs grow.
Quiet Operation
Designed for urban and industrial environments, the system operates at noise levels below 75dB, ensuring minimal disruption during continuous use, especially suitable for deployments near residential areas, office buildings, schools, and noise-sensitive facilities.
