Cooling Mode

When cabinet pack temperatures exceed preset thresholds, the TMS automatically initiates a cooling cycle:

• Activation thresholds: Cooling begins when the system average reaches 30°C (86°F) or when any individual pack exceeds 32°C (89.6°F).

• Deactivation thresholds: Cooling continues until the system average drops to 28°C (82.4°F) and all packs fall below 30°C (86°F).

• Process: Within 20 seconds, the coolant pump begins circulating a 50/50 glycol-water mixture through each pack’s cooling plates. After 30 seconds, the compressor engages, transferring heat from the liquid coolant into a refrigerant loop. Heat is then expelled via three high-efficiency fans at the rear of the cabinet.

• Target coolant temperature: 20°C (±1°C) / 68°F (±1.8°F).

• Control logic: Cooling takes priority over all other modes. If both heating and cooling thresholds are triggered, the system enters self-circulation mode to equalize pack temperatures without overcorrection.

This design ensures that internal cell temperature remains below 32°C (89.6°F), even during extreme heat waves with ambient temperatures greater than 40°C (104°F).

Hot Environment Performance

• Cabinets maintain rated continuous power up to 55°C (131°F) ambient.

• Cooling prevents accelerated degradation and derating during extended heat waves.

• Suitable for extreme-heat regions such as the Middle East, the Southwestern U.S., and Australia.
