Both charge and discharge functions increase battery temperatures. High rate battery
usage causes the largest temperature increase. The Alliance Intelligent Battery Series™
over temperature protection (OTP) circuitry disconnects the terminals if the battery
exceeds the temperature limits. During high rate battery usage, the user must ensure
that ambient operating temperature combined with the charge or discharge rate does
not exceed the operational temperature limits.
Under certain conditions, the Alliance Intelligent Battery Series™ terminals will exceed
the 70 °C touch temperature limit as described in UL 1973. For operation beyond those
touch temperature limits, not to exceed 90 °C, the Alliance Intelligent Battery Series™
will require the placement of guards to prevent accidental contact. American Battery
Solutions recommends that additional testing be conducted under specific use cases.
The gauge of wire may be changed depending on final temperature requirements and
application.
1.
Over Temperature Warning
-
Over Temperature Warning sets a warning flag if
any of the Battery cell Temperature goes above Maximum operating temperature.
This notifies the user the take appropriate actions and use the battery efficiently
without opening the FETs.
2.
Over Temperature Moderate
- Over Temperature Moderate flag is set if any of
the Battery cell Temperature goes above Charge Over Temperature Protection
Limit. This fault restricts the user from operating the battery pack in charging mode
by opening the FETs in Charge Mode. This helps the battery from protecting itself
from charging at above the rated temperature to maintain the life of the Battery.
3.
Over Temperature Severe -
Over Temperature Severe flag is set if any of the
Battery cell Temperature goes above Discharge Over 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 from protecting itself from
discharging at above the rated temperature to maintain the life of the Battery.
