Battery Energy Storage System (BESS) Chiller

Battery Energy Storage System (BESS) Chiller collects energy from sources like solar panels at the time of generation and stores it in rechargeable Li-ion batteries. This stored energy can then be discharged and utilised whenever needed for applications such as powering the grid, households, electric cars, and industrial or commercial facilities.

Challenges faced by BESS

  • Uncontrolled temperature and humidity can negatively affect the performance and lifespan of Lithium-ion batteries.
  • Exposure to extreme high or low temperatures during charging and discharging cycles may lead to:
    • Reduced battery life
    • Decreased performance (i.e. charging capacity)
    • Raise other safety concerns

Industrial AC Solutions for BESS Containers and Control Rooms

  • ATMOS, a leading manufacturer of Heavy-duty Industrial Air Conditioners, now provides a custom-built variable frequency HVAC unit designed specifically for Battery Energy Storage Systems (BESS). It ensures a stable and conditioned environment for battery packs.
  • The host computer of the BESS container (BMS or EMS) can monitor and control various HVAC parameters through a data communication interface.
  • The AC unit is engineered to operate reliably in outdoor ambient environments, with a working temperature range of -30 °C to 50 °C.

The Packaged Chiller with Air/Liquid Cooling System from ATMOS Features:

  • Integrated AC and DC design eliminates the need for PCS, LC, and other devices, reducing maintenance requirements and saving up to 29% space.
  • Simplified layout further optimises space utilisation.
  • Compact arrangement using standard 20-foot cabinets placed back-to-back for optimal layout.
  • Full water-cooling system with water-cooled PACK and water-cooled PCS for effective heat dissipation.
  • Three intelligent temperature control modes: rapid cooling, micro cooling, and heating, which automatically adjusts based on electrical core, environment temperature and operating conditions, reducing power consumption by up to 45%.
