A scalable power unit for powering one or more electric motors of a riding vehicle and/or a piece of outdoor power equipment includes a number of interconnected battery packs. The battery pack are received in a battery tray or stacked to form the scalable power unit. Each battery pack is configured to be removed and used separately or added to a combination of battery packs. A control unit selectively opens and closes switching elements to separately control the connections between the battery packs and an electrical load, such as a motor. During charging, the control unit opens and closes switching elements to control the charging rate of the individual battery packs. When the battery packs are connected to an electrical load, the control unit controls the state of the switching elements to selectively discharge the battery packs to power the riding vehicle and/or electric loads.

A vehicle-body front structure includes a partition wall portion which demarcates a vehicle cabin inside space, a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of a vehicle cabin, a panel reinforcement that is provided to a surface of the partition wall portion on the inside of the vehicle cabin and has a portion which extends in a vehicle width direction so as to surround at least a part of a periphery of the motor arrangement portion, and a central reinforcement which is provided to the surface of the partition wall portion on the inside of the vehicle cabin and extends from an intermediate portion of the panel reinforcement in the vehicle width direction to vehicle rear.

A vehicle-body front structure includes a partition wall portion which is provided to extend in a vehicle width direction in a vehicle front portion, a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of a vehicle cabin and in which at least a part of a traveling motor is capable of being arranged, and a reinforcement member which extends from the motor arrangement portion to vehicle rear. A rear portion of the reinforcement member is mounted on a inside-unit member which is provided in the battery unit.

A vehicle-body front structure includes a partition wall portion which demarcates a vehicle cabin inside space, a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of a vehicle cabin and in which at least a part of a traveling motor is capable of being arranged, and a reinforcement member which extends from an upper portion of the motor arrangement portion to vehicle rear and is inclined to be positioned lower toward the vehicle rear. A rear portion of the reinforcement member is mounted on a floor panel and a lid body of a battery unit.

A vehicle-front body structure includes a partition wall portion which demarcates a vehicle cabin inside space, a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of a vehicle cabin and in which at least a part of a traveling motor is capable of being arranged, a cross member which is fixed to a floor panel on a vehicle rear side of the motor arrangement portion and extends in a vehicle width direction, and a reinforcement member which couples the motor arrangement portion and the cross member together.

A vehicle-body front structure for an electric vehicle includes a front-side battery frame which extends in a vehicle width direction, a pair of left and right side frames which extend from the front-side battery frame to a vehicle front to be positioned on vehicle-width-direction outer sides, a left-side support mounted on the front-side battery frame and supports the left side frame from the vehicle-width-direction outer side, and a right-side support mounted on the front-side battery frame and supports the right side frame from the vehicle-width-direction outer side.

A vehicle-body front structure includes a front-side battery frame which is provided in a front of the battery casing, a pair of left and right side frames which extend from the front-side battery frame toward vehicle front to be positioned on vehicle-width-direction outer sides toward front, and a cross member suspended between left and right. Outer ends of the cross member in a vehicle width direction extend to the vehicle-width-direction outer sides of outer ends, in the vehicle width direction, of fronts of the side frames.

A vehicle-body front structure includes a pair of left and right side frames which extend from a front-side battery frame toward vehicle front to be positioned on vehicle-width-direction outer sides, a contactless charger between the left and right side frames, and a cross member between the left and right side frames. The contactless charger has a cross member housing configured to house the cross member.

A vehicle-body front structure for an electric vehicle includes a front-side battery frame which extends in a vehicle width direction, a pair of left and right side frames and which extend forward from the front-side battery frame, a cross member between the left and right side frames and, and reinforcement members and which extend toward vehicle rear from the cross member toward the front-side battery frame.

A military vehicle includes a cab having a rear wall, a bed positioned behind the cab, and an energy storage system. The energy storage system includes a lower support coupled to the bed, a battery supported by the lower support, a bracket coupled to the batter, and an isolator mount coupling the bracket to the rear wall. The isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the rear wall.
