Claim 1

A military vehicle comprising: a passenger cabin having a tunnel extending along at least a portion of a bottom thereof; a bed positioned behind the passenger cabin; a battery system positioned within the bed; a driveline including: an engine positioned forward of the passenger cabin; one or more accessories coupled to the engine; and a motor/generator coupled to the engine and electrically coupled to the battery system, the motor/generator at least partially positioned within the tunnel; wherein the driveline is operable in an electric-only or silent mode where (i) the engine is off and (ii) the motor/generator receives power from the battery system to drive an axle of the military vehicle; and wherein the driveline is operable in an engine mode where the engine at least partially drives the axle; and a controller configured to switch the driveline from the electric-only or silent mode to the engine mode in response to a state-of-charge of the battery system falling below a charge threshold. a passenger cabin having a tunnel extending along at least a portion of a bottom thereof; a bed positioned behind the passenger cabin; a battery system positioned within the bed; a driveline including: an engine positioned forward of the passenger cabin; one or more accessories coupled to the engine; and a motor/generator coupled to the engine and electrically coupled to the battery system, the motor/generator at least partially positioned within the tunnel; wherein the driveline is operable in an electric-only or silent mode where (i) the engine is off and (ii) the motor/generator receives power from the battery system to drive an axle of the military vehicle; and wherein the driveline is operable in an engine mode where the engine at least partially drives the axle; and an engine positioned forward of the passenger cabin; one or more accessories coupled to the engine; and a motor/generator coupled to the engine and electrically coupled to the battery system, the motor/generator at least partially positioned within the tunnel; wherein the driveline is operable in an electric-only or silent mode where (i) the engine is off and (ii) the motor/generator receives power from the battery system to drive an axle of the military vehicle; and wherein the driveline is operable in an engine mode where the engine at least partially drives the axle; and a controller configured to switch the driveline from the electric-only or silent mode to the engine mode in response to a state-of-charge of the battery system falling below a charge threshold.
