A saddled electric vehicle () having a battery () that is attachable to and detachable from the vehicle () includes a vehicle electronic lock () which enables the vehicle () to be locked and unlocked, a lock control unit () which controls the vehicle electronic lock (), and a sub battery () which supplies electric power to the lock control unit (), in which the lock control unit () enables the vehicle to be unlocked in a state in which the battery () is removed from the vehicle ().

Saddled electric vehicle

A saddle type electric vehicle () includes a charging cord () that is connectable to an external power supply, a cord accommodating section () configured to accommodate a charging cord (), and a step floor () on which an occupant places his/her legs, a center tunnel (CT) bulging above the step floor () is provided in front of a front end of a seat () and below a handle (), and the cord accommodating section () is disposed in the center tunnel (CT).

Saddle type electric vehicle

A saddle-type electric vehicle (A, orB) includes an electric motor () for vehicle traveling, a battery () which supplies electric power to the electric motor (), a power control unit () which controls the electric motor (), step floors () on which a rider places his/her feet, a center tunnel (CT) which extends in a vehicle front-rear direction at a left-right center portion of the step floors (), and a charger () mounted on the vehicle body and configured to charge the battery (), in which the power control unit () is disposed inside the center tunnel (CT), and the charger () is disposed to overlap the power control unit () in a plan view.

Saddle-type electric vehicle

A saddled electric vehicle (A, orB) includes an electric motor () for vehicle traveling, a battery () which supplies electric power to the electric motor (), a power control unit () which controls the electric motor (), a vehicle body frame () which supports the battery () and the power control unit (), step floors () on which a rider places his/her feet, and a center tunnel (CT) which extends in a vehicle front-rear direction at a left-right center portion of the step floors (), in which the power control unit () is disposed inside the center tunnel (CT), and the vehicle body frame () includes a pair of left and right frame members (, and), and the power control unit () is disposed on an inward side in a left-right direction of the pair of left and right frame members (, and).

A storage battery management system manages a state of a storage battery that is detachably mounted. The storage battery management system includes an activation signal generation unit configured to generate an activation signal for setting a mounted storage battery to an available state, a management unit configured to manage the mounted storage battery that has received the activation signal and identification information of the mounted storage battery in association with each other, an activation signal transmission line configured to electrically connect a storage battery management unit of the mounted storage battery and the activation signal generation unit with each other, and a signal transmission line configured to electrically connect the storage battery management unit and the management unit to each other.

Storage battery management system, moving body, storage battery, and storage battery management method

An electric circuit switches connection among a plurality of storage cell units including a first storage cell unit and a second storage cell unit, a load of the plurality of storage cell units, and a power supply supplying power to the plurality of storage cell units. The electric circuit includes: a first rectifier configured to rectify a current flowing between a first pole terminal of the power supply and a first pole terminal of the first storage cell unit with homopolarity as polarity of the first pole terminal of the power supply; a second rectifier configured to rectify a current being different from the current and flowing between the first pole terminal of the power supply and a first pole terminal of the second storage cell unit with homopolarity as the polarity of the first pole terminal of the power supply; and a connection switching device configured to connect the plurality of storage cell units in series between the first pole terminal of the first storage cell unit and the first pole terminal of the second storage cell unit and release the series connection of the plurality of storage cell units during a period in which the power supply supplies power to the plurality of storage cell units.

Electric circuit and diagnosis method

A charging device starts charging a battery mounted on an electrically driven vehicle in accordance with simplified operating steps. A charging supply connector is connected to a charging port mounted on a vehicle body side. The charging supply connector includes a lock lever displaceable between a locking position, for engagement with a hook mounted on the charging port, and a lock release position where the lock lever is released from the hook. The lock lever is spring-biased to the locking position. A manipulation lever is connected to the lock lever by a link, and is operable to move the lock lever between the locking position and the lock release position. When the lock lever is at the lock release position, the lock lever, the link or the lock lever and the link interferes with an operation range of a charging start switch, to prevent operation thereof.
