162 kWh

This 162.78kWh container ESS adopts long-life LiFePO4 cells, distributed intelligent BMS,

full thermal & fire safety, high-efficiency bidirectional PCS and EMS remote monitoring for versatile energy storage use.

• Core Advantage

¹ Premium Cell & Stable Module Hardware 

This 162.78kWh container energy storage system adopts 314Ah square aluminum-shell LiFePO4 cells with ≥6000 charge cycles and 110Wh/kg energy density,

operating steadily between -20℃ and 60℃. Each 18S module uses laser welding plus air cooling,

supporting continuous 314A charge/discharge current for long-lasting consistent power output.

² Layered Distributed Intelligent BMS

Compliant with national industrial standards, the distributed BMS consists of BCU master control and BMU slave sampling units.

It delivers high-precision detection of cell voltage and multi-channel temperature, external MOS passive balancing with TVS anti-static protection,

and accurate SOC/SOH calculation. Isolated CAN & RS485 ports enable seamless data linkage with PCS and EMS, realizing real-time monitoring and multi-layer fault protection.

³ Full-Range Safety & Flexible System Adaptability

The integrated cabinet is equipped with industrial air cooling with customized air ducts and three-mode heptafluoropropane fire suppression for complete thermal and fire safety.

Matching bidirectional PCS reaches up to 98% efficiency, supporting both grid-tied and off-grid operation.

Paired with independent EMS, the whole system fits commercial peak shaving, photovoltaic matching, and emergency backup power scenarios.

' Energy storage converter solution（PCS）

The energy storage system of this project uses one rated power 50kW energy storage  converter to realize bidirectional energy conversion between the energy storage  battery and the AC grid,

including AC/DC bidirectional converter power modules, controllers, and electrical protection devices.

The energy storage bidirectional converter has the function of parallel and off-grid operation, which can guarantee the continuous power supply of important loads;

It can cooperate with the monitoring system to realize the advanced application of the power system.
