Controller (12) of power storage pack (10) communicates with controller (32) of electric moving body (30) in a state where power storage pack (10) is mounted to the electric moving body. Communication wiring (Lc1) connects a node of power line (Lp1) on power source terminal (Tp) side relative to first switch (RYp) and controller (12) of power storage pack (10). Overvoltage protection circuit (19) turns off second switch (SWc) inserted into communication wiring (Lc1) upon detecting an overvoltage of power line (Lp1) during communication between controller (12) of power storage pack (10) and controller (32) of the electric moving body.

A battery pack includes a rechargeable battery, a charge FET including a parallel diode connected in series with the battery, and a control circuit configured to control turning on and off of the charge FET. The control circuit includes a discriminating circuit configured to detect a bicycle-mounted state and a charger-connected state, and a memory configured to store a full charge voltage of the battery. The control circuit is configured to, while the discriminating circuit detects the bicycle-mounted state. turn off the charge FET. The control circuit is configured to, while the discriminating circuit detects the charger-connected state, stop charging the battery by switching the charge FET to turn off the charge FET upon detecting that a voltage of the battery charged by a charger becomes higher than the full charge voltage.

A power integration system with motor drive and battery charging and discharging function includes a motor, a power integration circuit, and a battery. The power integration circuit includes an inverter and a charger. The inverter includes multi-phase bridge arms, and each bridge arm has an upper switch and a lower switch. Each bridge arm is correspondingly coupled to each phase winding of the motor. The charger includes a front-end DC conversion path, and the upper switch and the lower switch of at least one bridge arm of the shared inverter. The battery is coupled to the power integration circuit. The power integration circuit receives a DC power provided by a DC power apparatus, and the charger converts the DC power to charge the battery. The battery provides the power required to drive the motor by the inverter.

A motorcycle, or saddle type vehicle, is disclosed that may have at least one seat and at least two wheels, at least one hub electric motor. A large dry storage compartment may be positioned between the rider and steering mount. A rechargeable battery and battery management system may be located below the storage compartment in a battery housing, where the battery housing may be a structural component of the chassis. A rear electronics housing may be attached to and located behind the battery housing, and may contain major electrical components such as electric motor controller and contactors. Two structural members, or frame side rails, may form sides of the storage compartment and extend between the electronics housing and steering mount. The electronics housing may also connect to the battery housing such that the battery housing reinforces and strengthens the chassis, or structural frame. A secondary storage compartment may be located under the seat. Additionally, the storage compartments may have electronic locking mechanisms that are activated via a wireless connection to a remote electronic device. The rear suspension may include a swingarm on one side of the vehicle.
