Abstract
Briefly stated, one aspect of the present disclosure is directed to a firefighting apparatus. The firefighting apparatus includes a movable fire truck chassis and a battery array movable with the movable fire truck chassis and operatively connected to provide power for operating at least one pump of the firefighting apparatus. A pre-connect pump has a pre-connect inlet and a pre-connect outlet and is electrically powered by the battery array. A controller is operatively connected to the pre-connect pump and configured to control the pre-connect pump under a standby condition selected to maintain the firefighting apparatus in a state of readiness to pump firefighting fluid. The controller reduces a power-consumption rate of the pre-connect pump while maintaining the standby condition as compared to operating the pre-connect pump under an idle condition. The standby condition requires pumping by at least one pump within the firefighting apparatus for maintenance of the standby condition.
