OG exemplary drawing
 
1. A fire fighting vehicle comprising:
a chassis;
a front axle;
a rear axle;
an engine;
a battery system;
an electromagnetic device coupled to the battery system and at least one of the front axle or the rear axle, the electromagnetic device including at least one electric motor;
an accessory drive positioned to receive a mechanical input from the engine and the electromagnetic device; and
a controller configured to selectively engage a plurality of operational modes including a standby mode and a hybrid mode;
wherein, according to the standby mode, the controller is configured to operate the electromagnetic device using stored energy stored in the battery system to drive the accessory drive with the engine off; and
wherein, according to the hybrid mode, the controller is configured to operate both the engine and the electromagnetic device.
 
13. A fire fighting vehicle comprising:
a powertrain including an engine, a battery system, and an electromagnetic device coupled to the battery system, the electromagnetic device including at least one motor;
a pump configured to provide a fluid from a fluid source to a fluid outlet;
a power divider positioned between the engine, the pump, and the electromagnetic device;
an accessory system including a first accessory and a second accessory, wherein the first accessory is mechanically operated and the second accessory is electrically operated; and
a controller configured to selectively operate the powertrain in a standby mode that includes at least one of (i) operating the electromagnetic device using stored energy stored in the battery system to drive the first accessory or (ii) operating the second accessory using the stored energy in the battery system.
 
15. A fire fighting vehicle comprising:
a driveline including an engine, a battery system, an electromagnetic device including at least one electric motor, a front axle, and a rear axle; and
a controller configured to:
operate the electromagnetic device using stored energy in the battery system to drive at least one of the front axle or the rear axle with the engine off at vehicle startup; and
start the engine in response to a condition being met and operate both the engine and the electromagnetic device to provide hybrid vehicle operations;
wherein the hybrid vehicle operations include operating the engine to perform a first operation and operating the electromagnetic device to perform a second operation;
wherein the first operation includes operating the engine to provide a mechanical engine output to at least one of (i) a pump, (ii) an accessory drive, or (iii) the electromagnetic device; and
wherein the second operation includes operating the electromagnetic device to at least one of (i) provide a mechanical motor output to the accessory drive using the stored energy in the battery system, (ii) generate energy based on the mechanical engine output received from the engine, or (iii) provide the mechanical motor output to the at least one of the front axle or the rear axle using at least one of (a) the stored energy in the battery system or (b) the energy generated based on the mechanical engine output.
