5.1 Battery Management System Protections
The Battery Management System's (BMS) primary function is to monitor
cell module voltage and temperature, and battery current. The BMS
uses this information to maintain cell operation within specification. If a
parameter falls outside of operating specifications the BMS will disconnect
and protect the battery from:
1.
Over voltage.
Over voltage protection occurs when charge voltages are
too high.
2.
Under voltage.
Under voltage protection occurs during discharge when
the voltage is discharged too low.
3.
Over-current.
Over-current protection can occur during charge or
discharge. This may happen when powering up a load (short and high
inrush current) or during sustained currents above specified limits.
4.
Over-temperature.
Over-temperature protection can occur during charge
and discharge.
5.
Under-temperature.
Under-temperature protection can occur during
charge and discharge.
Refer to
Table 2-4.
DLB Protection Specifications
for trigger and recovery values.
The BMS will reconnect when recovery thresholds are met. If the BMS
disconnects due to low voltage protection, the loads must be removed
before the BMS will be able to reconnect. If the system has a constant
parasitic draw a physical disconnect switch is recommended to aid in
reconnecting the battery.
