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.
Intelligent Safety Management
The Pion Power Liquid Cooling BESS features a multi-layer protection architecture designed to detect, suppress, and prevent thermal events and electrical faults, even under extreme conditions.
Pack-Level Fire Protection
Unlike traditional cabinet-level systems, Pion Power Liquid Cooling BESS implements pack-level suppression, targeting thermal incidents where they begin for faster, more effective response
Multi-Layer Short Circuit Protection
Short-circuit protection is applied across the battery, PCS, and control system to isolate problems quickly and safely.s
PCS Communication Protection
The PCS is designed with multiple communication safeguards to keep the system stable during power or signal issues.
Cluster-Level Battery Management
Each battery cluster is monitored and managed separately in real time. This allows the system to quickly detect exactly where a problem occurs, making troubleshooting faster and easier. It also helps balance voltage and current more efficiently, reducing energy loss and extending battery life.
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.

Enhanced Safety Features
Pack-Level Fire Protection
The system integrates smoke, CO, and temperature sensors to continuously monitor internal air conditions.When abnormal gas levels or heat are detected, high-speed exhaust fans are automatically activated to expel flammable gases. This process reduces gas concentration, helps relieve internal pressure, and prevents the risk of explosion.
Water-Based Fire Suppression
For projects requiring the highest level of fire control, the system supports optional water-based fire suppression, offering enhanced protection for mission-critical installations
Superior dust and water resistance
Pion Power Liquid Cooling BESS is built for reliability with an IP67-rated battery pack and IP55 system enclosure, offering superior dust and water resistance, even in harsh outdoor conditions.
