System components:

The ESS mainly consists of lithium battery packs (PACK), Power Converter System (PCS), DC-DC Converter (DCDC) (optional), Rack Control Module (RCM), Liquid Thermal Management System (LTMS), and Thermal Runaway Suppression Device (TRSD). It stores and releases electricity through the control of the RCM.

• Battery charging: Controlled by the RCM, the electricity from the mains or other power supplies is converted by the PCS into DC electricity, which is then stored in batteries.
• Battery discharging: Controlled by the RCM, the electricity released by batteries is converted by the DCDC (optional) and PCS into AC electricity, which is then supplied to loads.
• Integrated design: The internal components of the ESS are integrated to reduce the footprint, simplify the installation and O&M process, and greatly reduce the installation time and cost.
• Smart thermal management with air and liquid cooling: The ESS uses thermal management and control technologies to implement various functions including active liquid cooling, natural air cooling, waste heat recovery, low temperature heat pump heating or electric heater, and intelligent dehumidification, achieving optimal energy efficiency throughout the year
