Low Temperature Operation
At low temperatures, the maximum available discharge power decreases due to
increased internal impedance at lower temperatures.
1.
Under Temperature Warning
– Under Temperature Warning sets a warning flag
if any of the Battery cell Temperatures go below minimum operating temperature.
This notifies the user the to take appropriate actions and use the battery efficiently
without opening the FETs.
2.
Under Temperature Moderate
- Under Temperature Moderate flag is set if any of
the Battery cell Temperatures go below Charge under Temperature Protection
Limit. This fault restricts the user from operating the battery pack during charging
mode by opening the FETs in Charge Mode. This helps the battery protect itself
from charging at below the rated temperature to maintain the life of the Battery.
3.
Under Temperature Severe
– Under Temperature Severe flag is set if any of the
Battery cell Temperature goes below Discharge under Temperature Protection.
This fault restricts the user from operating the battery pack during Driving mode
by opening the FETs in Drive Mode. This helps the battery protect itself from
discharging at below the rated temperature to maintain the life of the Battery.
Charging a Single Battery Module
The Alliance Intelligent Battery Series™ is compatible with most common 48-volt,
lithium-ion battery chargers. A single Alliance Intelligent Battery Series™ can accept
continuous charge current up to 20 amps for the 48V module at certain temperature
and SOC range. Higher current for short durations is allowed. However, in some
situations, internal component temperatures may be exceeded causing performance
to be curtailed by the battery’s protection circuitry.
