HELIOS ESS Environmental Specifications
Specification | 52-48-16000 | 900-0077 |
|---|---|
Rated Altitude (a) | Altitude of up to 2,000 m (6,561 ft) does not affect operating characteristics |
Relative Humidity | 5 to 95% (Non-condensing) |
Charge Operating Temperature Range (b)(c) | 4°C to 55°C (39.2°F to 131°F) |
Discharge Operating Temperature Range (b) | -25°C to 55°C (-13°F to 131°F) |
Internal Heater Operating Temperature Range (d) | -25°C to 8°C (-13°F to 46.4°F) |
Storage Temperature (1 month) (e) | -20°C to 55°C (-4°F to 131°F) |
Storage Temperature (6 months) (e) | -10°C to 30°C (14°F to 86°F) |
(a) Consider reducing charge parameters on power conversion equipment at higher altitudes.
(b) Specifies the temperature of the cells and not the ambient temperature. Ambient temperature and cell temperature may not be the same.
(c) Although the Battery Management System (BMS) does not allow charging when cells are below 4°C (39.2°F), the battery has a heater that warms the battery to a temperature that enables charging to resume at 4°C (39.2°F).
(d) When the HELIOS ESS battery cells are between -25°C (-13°F) and 5°C (41°F) and either connected to a charging source or the battery SOC is 50% or more, energy is diverted to the internal heater until the battery reaches 8°C (46.4°F).
(e) Storage outside of specified temperatures will result in permanent capacity loss and void the warranty.
