A power supply station includes a power supply device that is accommodated in a housing. The power supply device includes a power supply coil that supplies electric power to a power reception device via a power reception coil, and an electric power supply circuit that supplies AC power to the power supply coil. The housing is provided with an accommodating section that accommodates the power supply coil and is provided at a position facing the power reception coil in a state in which the two-wheeled vehicle is parked at a predetermined position, and a cover section that is formed to surround at least a part including an upper end of an outer periphery of the accommodating section and to protrude toward the two-wheeled vehicle from a surface of the accommodating section on a side facing the power reception coil of the parked two-wheeled vehicle.

A regenerative braking energy dissipater system which is adapted to dissipate energy from a regenerative brake in the case when the battery cannot accept further energy. The system may switch the energy flow from the battery to a dissipater when the battery has reached a high level of charge. The dissipater may include load resistors. The system may be designed such that the airflow around the dissipater flows over and under the dissipating plate.

A personal mobility that adjusts power supply based on a state of a kickstand is provided. The personal mobility includes a main body, a kickstand provided rotatably on one end in the main body, and a variable resistor that is provided on an axis of the kickstand as an axis. The variable resistor is configured to output a voltage that varies based on a position of the kickstand. A controller is then configured to adjust power supply when the position of the kickstand is a parking position.

A power supply device comprising a group of at least one power supply cell, means for managing the cell group comprising a passive balancing unit of said cells, the device being wherein, during a request to move into long-duration storage mode of the device, the management means are configured to, via the passive balancing unit, discharge the cell group until the cell group reaches a target charge state or a target charge state range, if a charge state of the cell group is greater than the target charge state or the target charge state range.

Provided is a battery share system in which a necessary change in the scale of a battery exchange device can be made with ease and at low cost even after the start of operating a service. A plurality of battery charging modules for holding a battery pack are attached to a support post to form a battery exchange apparatus. A battery charging module is detachably attached to the support post. A battery charging module includes a tray for guiding the battery pack to a predetermined mounting position and holding the battery pack at the mounting position. The tray includes a power transmitter terminal for transmitting charging power to the battery pack, a communication terminal for transmitting battery management information from the battery pack, and an indicator for indicating a state-of-charge of the battery pack.

An electric bicycle includes a front wheel drivable by a front wheel electric motor that has a battery as a power supply; a rear wheel drivable by a rear wheel electric motor that has a battery as a power supply; pedal for inputting pedaling force of a driver to at least one of the front wheel or the rear wheel; at least one travel operator that inputs a desired travel state of the driver; a front wheel controller that controls a rotation of the front wheel electric motor in accordance with a situation of the front wheel and an input from the travel operator; and a rear wheel controller that controls a rotation of the rear wheel electric motor in accordance with a situation of the rear wheel and an input from the travel operator. Two electric motors, the front wheel electric motor and the rear wheel electric motor, are provided, at least one of the front wheel or the rear wheel is driven by the corresponding electric motor and a load of at least one of the front wheel electric motor or the rear wheel electric motor is reduced by the pedaling force of the driver.

A control device comprises: a first identification information acquiring unit configured to acquire first identification information which is identification information for identifying the power accumulation device; a second identification information acquiring unit configured to acquire second identification information which is identification information for identifying the power device; and a determining unit configured to determine, when the first identification information and the second identification information do not match, (i) to prohibit or limit power exchange between the power accumulation device and the power device, (ii) to output an identification abnormality signal indicating that the first identification information and the second identification information do not match, or (iii) not to output an identification normality signal indicating that the first identification information and the second identification information match.

A battery module includes a plurality of battery cells disposed in at least two rows. The battery cells in adjacent rows are offset from each other. Each of the plurality of battery cells includes a cover and a first terminal that extends from the cover outward. The first terminal is configured to be coupled to a second terminal on an adjacent battery cell. The plurality of battery cells are electrically coupled to each other in a zigzag pattern via the first and second terminals.
