Technologies described herein are directed to the prioritized delivery of energy to primary and accessory electrical components associated with a vehicle that is at least partially electrically powered, as well as to a power source of the vehicle itself. To operate accessory electrical components in parallel to delivering power to a vehicle battery, the embodiments described herein facilitate understanding dynamic energy available to the accessory electrical components as well as the vehicle battery, and then managing the usage of energy in a prioritized manner to optimize the whole system performance that is aligned with user priorities with regards to energy availability and energy needs.

To provide a construction machine capable of preventing damages of batteries placed on a machine-body frame. A construction machine comprises a machine-body frame, a supporting plate installed on the machine-body frame via elastic mounts, and batteries fixed to a topside of the supporting plate. Welding is not performed on the supporting plate.

A motor unit including: a first motor that drives a vehicle; a second motor that drives an auxiliary machine of the first motor; a first inverter that controls the first motor in response to a control signal transmitted from a main control device of the vehicle; and a second inverter that controls the second motor in response to a drive command signal for controlling the second motor transmitted from the first inverter, in which the second inverter transitions to an operation state of suppressing power consumption of the second inverter when reception of the drive command signal is finished.

The disclosed vehicle braking device controls a hydraulic brake system (2) and a regeneration brake system (3) mounted on a vehicle (1) in accordance with an acceleration value and a brake value, and includes a first divider (11), a second divider (12), and a controller (13). The first divider (11) divides a driver demand torque set according to the accelerator value into a target coast torque and a remaining torque. The second divider (12) divides a sum of a deceleration torque set according to the brake value and the target coast torque divided by the first divider (11) into a hydraulic-brake demand torque and a regeneration-brake demand torque. The controller (13) controls the hydraulic brake system (2), using the hydraulic-brake demand torque, and controls the regeneration brake system (3), using a total regeneration brake torque calculated from the remaining torque and the regeneration-brake demand torque. This configuration can improve the feeling of operating the brake, resolving the feeling of the shortage of deceleration.

Service vehicles, such as compact service carts (e.g., compact electric vehicles), are described that support a variety of service applications. One such vehicle (100) generally includes a vehicle platform (102) and a service box (104). The vendor box (104) includes canopy doors (106) for each of the sides (110, 112, and 114). The canopy doors (106) are movable between a closed position, where the canopy door (106) encloses the service area (108), and an open position where the canopy doors (106) extend outwardly from the sides 110, 112 and 114. In the open position, the doors (106) thus function as a canopy to provide shade at the service area 108 and maximize the space available for rendering services on the sides (110, 112 and 114) of the box (104). The inventive vehicles are adaptable to meet the needs of a wide variety of service applications including food and beverage applications, medical applications, and others.
