Motor Vehicle
A motor vehicle has a motor, an inverter, a first power storage device, with a large-capacity characteristic, a second power storage device, with a high-power characteristic, a power converter and a circuit. The power converter has a voltage step down function during power driving. In the circuit, the power converter is connected to the first power storage device and the second power storage device. Thus, the first power storage device and the second power storage device are parallel to each other. During the power driving of the motor, the power converter steps down an output voltage of the first power storage device to supply energy from the first power storage device and the second power storage device to the inverter.

Controlling electrical access to a lithium battery on a utility vehicle
Techniques involve controlling battery access on a utility vehicle. Such techniques involve monitoring status of input signals from a group comprising: a lithium battery system, a keyed switch, and a charging receptacle, comparing the status of the input signals to timeout settings stored in memory of the motion control system, initiating a timer based on comparison of the input signals to the timeout settings, and disconnecting at least one direct current (DC) path between a lithium battery interface and a power distribution interface of the utility vehicle in response to expiration of the timer. Such techniques further involve, after disconnecting, reconnecting the at least one DC current path between the lithium battery interface and the power distribution interface in response to a change in status of at least one of the input signals. Such techniques may be performed by a motion control system of the utility vehicle.

Regenerative Braking System, and Electrically Driven Work Vehicle Using the Same
When regeneration operation is being performed, electric power on a main-machine side is supplied to an auxiliary-machine side, a voltage on the auxiliary-machine side is controlled to become a first voltage value predetermined on the basis of operating voltage specifications of an auxiliary apparatus, a generator on the auxiliary-machine side is deactivated to stop supply of electric power to the auxiliary-machine side, and electric power on the auxiliary-machine side is supplied to a power storage apparatus. When the regeneration operation is ended, the supply of the electric power from the main-machine side to the auxiliary-machine side is stopped, the generator on the auxiliary-machine side is activated, the generator on the auxiliary-machine side is controlled such that a voltage on the auxiliary-machine side becomes the first voltage value, electric power of the power storage apparatus is supplied to the auxiliary-machine side, and the voltage on the auxiliary-machine side is controlled to become a second voltage value higher than the first voltage value. This enables reduction of fluctuations of a voltage supplied to auxiliary machines at a time of switching of regeneration operation by travel motors.
