Protection against under-
voltage.
Charge battery.
Protection against over-
temperature or under-
temperature
(cell
temperature is lower than
-20°C or higher than
80°C).
Regulate cell temperature
in the range of -20°C to
60°C for discharge.
Protection against over

Ensure power shelf setting
is not over 1C for battery.
Protection against over-
temperature or under-

50°C for charge
System failure detected
Shut down system and
call maintenance service.
