Abstract
The method is directed to preserve the starter/alternator in an IC engine installation from potential failure owing to insufficient electrical charge in the system energy storage device. The system controller monitors starter/alternator controller signals relating to energy storage device charge level and whether the starter/alternator is available for operation. When monitored charge is detected to be insufficient to operate the starter/alternator, the starter/alternator is disabled and the system controller provides this information to the vehicle operator as a warning signal that the starter/alternator is disabled. Once the operator has effected a remedy (i.e., recharging or replacing the energy charging device), the starter/alternator is again made available for operation.
