OPERATING MODES

Thermal Activation Ranges

• Cooling: Engages when the average battery pack temperature exceeds 30°C (86°F) or a single pack exceeds 32°C (89.6°F). Cooling stops when the average pack temperature drops to 28°C (82.4°F), and all packs are below 30°C (86°F). For more information, see Cooling Mode.

• Heating

  • Engages during charge when the average battery pack temperature is less than 10°C (50°F) or the temperature of any individual battery pack is 5°C (41°F) or less. The heating turns off when the average pack temperature reaches 25°C (77°F), and all individual packs are 20°C (68°F) or warmer.

  • Engages during discharge when the average battery pack temperature is less than -5°C (23°F) or the temperature of any individual battery pack is -10°C (14°F) or less. The heating turns off when the average pack temperature reaches 25°C (77°F), and all individual packs are 20°C (68°F) or warmer.
    For more information, see Heating Mode.

• Self-Circulation: Equalizes temperature when it diverges between the battery packs.

• Standby: Active monitoring with no heating or cooling when all packs are in a safe range.
