Definition and Significance of Core Parameters
261 kWh (kilowatt-hours) - Energy Capacity:
■This indicates the maximum electrical energy the battery can store: approximately 261 kilowatt-hours (kWh).
■This capacity level is considered medium to large scale in mobile energy storage equipment, commonly used in medium to large-scale temporary power supply or peak shaving scenarios.
160 kW (kilowatts) - Rated Output Power:
■This indicates that the equipment can continuously output a maximum AC or DC power of 160 kilowatts (kW).
■This determines the size of the load the system can drive during discharge (e.g., generator replacement, equipment power supply, etc.).
Trailer-Mounted / Mobile:
■The system is integrated onto a towable chassis/frame, allowing for rapid deployment between sites via road transport.
■Compared to fixed energy storage cabinets, the biggest advantage of the mobile system is that it can be put into use without any construction work.

Key components of the system
Lithium-ion battery energy storage system (BESS)
- Typically, lithium iron phosphate (LFP) batteries are used due to their high safety and long cycle life.
- The battery cell configuration (such as 1P260S, etc.) determines the voltage and current characteristics.
Battery Management System (BMS)
- Responsible for monitoring and controlling the voltage, temperature, and SOC (State of Charge) of the battery pack.
- Improves safety and extends battery life.
Inverter / Power Conversion System (PCS)
- Converts DC power from the battery into AC power (output to the load or the grid).
- Determines the maximum output power; in this example, approximately 160 kW.
Thermal management system (liquid cooling or air cooling)
- Controlling battery temperature; liquid cooling allows for more precise regulation and adaptation to extreme environments.
- Large-scale systems often utilize liquid cooling solutions to improve safety and lifespan.
Fire protection and safety systems

Mobile energy storage is not a miracle solution; its value lies in its practical performance in delivering power on demand. The combination of 261kWh and 160kW is not an exaggerated specification, but rather precisely what is needed to solve real-world power problems on site. It won't change the world, but it will genuinely change the way work is done at individual sites. That's important enough.
