Abstract: Sneaking of a charging current to a load is avoided, a voltage of a battery is not output to terminals of a connector, and the number of installed switch elements that make conductive or interrupt a feeding path is minimized. A battery pack including a battery that supplies power to a load and to which power is supplied from a charger includes: a relay connector including a first terminal, a second terminal, and a third terminal; a first feeder that connects the load to the first terminal of the relay connector; a second feeder that connects one electrode terminal of the battery to the second terminal of the relay connector; a third feeder for which one terminal is connected to the third terminal of the relay connector; and a switch element that is connected between the other terminal of the third feeder, and the other electrode terminal of the battery.

Abstract: A motor-driven supercharger includes a compressor, an electric motor, and a controller. The compressor is arranged in the intake passage of the engine. The electric motor drives the compressor. The controller is configured to start detection of the rotational position of the electric motor at least on the condition that a brake operation amount, which is the operation amount of a brake operation member of the vehicle, becomes less than or equal to a threshold. The controller is configured to start forced induction with the electric motor when an acceleration operation amount, which is the operation amount of an acceleration operation member of the vehicle, becomes more than or equal to a threshold.

Abstract: Sneaking of a charging current to a load is avoided, a voltage of a battery is not output to terminals of a connector, and the number of installed switch elements that make conductive or interrupt a feeding path is minimized. A battery pack 100 including a battery 10 that supplies power to a load 20 and to which power is supplied from a charger 40 includes: a relay connector 36 including first, second, and third terminals; a first feeder 13 that connects the load to the first terminal of the relay connector; a second feeder 11 that connects one electrode terminal of the battery to the second terminal of the relay connector; a third feeder 16 for which one terminal is connected to the third terminal of the relay connector; and a switch element 16a that is connected between the other terminal of the third feeder, and the other electrode terminal of the battery.

Abstract: The present application relates to a vehicle and a method of limiting a vehicle speed during evacuation running designed to prevent a normal battery block from being overcharged by regenerative electric power during evacuation running, in which a vehicle driven by a parallely connected battery blocks runs under a condition in which some abnormal battery blocks are separated. The method may include determining whether a vehicle is performing evacuation running, calculating receivable regenerative electric power for the battery blocks used for running of the vehicle, calculating a limit speed of the vehicle according to the receivable regenerative electric power, and limiting the speed of the vehicle to the limit speed or to a speed lower than the limit speed.
