A military vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a driveline. The driveline includes an engine, an energy storage system, a front end accessory drive positioned in front of and coupled to the engine, a transmission coupled to at least one of the front axle or the rear axle, a second motor coupled to the transmission and electrically coupled to the energy storage system, and a clutch positioned between the engine and the second motor. The front end accessory drive includes an air compressor and a first motor. The first motor is electrically coupled to the energy storage system. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. The driveline is operable in an engine-only mode and an electric-only mode.

A power supply system includes a first energy storage, a second energy storage, a power transmission circuit, and circuitry.

According to a control method for a hybrid vehicle that is caused to run by a drive motor as a load being supplied with electric power of a battery and electric power generated by an electric generator, a total distance to empty is calculated on the basis of a shortage of a generating power output of the electric generator with respect to a required running power output and an amount of charge remaining in the battery. Specifically, a length of time for which the shortage of the generating power output of the electric generator with respect to the required running power output is covered by the amount of charge remaining in the battery is calculated, and a distance that the hybrid vehicle can run for this length of time is set as a total distance to empty.

A method of designing a machine on which a drive motor, a fuel cell stack, and a secondary battery are mounted includes: determining a maximum output of the drive motor to be a first output value and an output of the drive motor when a vehicle travels under a cruise condition to be a second output value; determining the number of fuel cell stacks to be mounted to be n; and determining a maximum output of the secondary battery to be a value obtained by subtracting a value obtained by multiplying a maximum output of the fuel cell stack by the n, from the first output value. A value obtained by multiplying the third output value by the n is equal to or larger than the second output value, and a value obtained by multiplying the third output value by (n−1) is less than the second output value.
