Abstract: In a discharging operation of a vehicle storage battery, a controller switches between a full-wave rectification operation of full-wave rectify a voltage across a second winding while maintaining a second short circuit in an open state, and a full-wave voltage doubling rectification operation of full-wave voltage doubling rectify a voltage across second winding while maintaining second short circuit in a closed state, based on magnitude relationship between DC voltage across first terminals and DC voltage across second terminals. In a charging operation, controller switches between a full-wave rectification operation of full-wave rectify a voltage across a first winding while maintaining a first short circuit in an open state, and a full-wave voltage doubling rectification operation of full-wave voltage doubling rectify a voltage across first winding while maintaining first short circuit in a closed state, based on magnitude relationship between DC voltage across first terminals and DC voltage across second terminals.

Abstract: An electric bicycle includes: an electric motor; a storage unit in which control software for controlling the electric motor is stored; a control unit configured to run the control software stored in the storage unit; and a communication interface unit to which a piece of hardware is removably and communicably connected. The control unit is configured to run an other piece of software different from the control software to control the piece of hardware which is communicably connected to the communication interface unit. The other piece of software is installed in the storage unit. Each of the control software and the other piece of software communicates using a distributed-communication protocol.

Abstract: A charge-discharge management device includes an instruction unit, an temperature input unit and a setting unit in order to manage charge and discharge states of a storage battery for supplying and receiving electric power to and from a distribution network for supplying electric power to an electric load. The instruction unit indicates magnitude of a charge current for the storage battery. The temperature input unit obtains a battery temperature of the storage battery. The setting unit sets the magnitude of the charge current to a first standard value if the battery temperature is in a normal range. If the battery temperature is out of the normal range, the setting unit sets the charge current to be below the first standard value and more increases a difference between the charge current and the first standard value as a degree of deviation from the normal range is larger.
