A battery pack is provided. The battery pack including a plurality of battery cells; a cell holder including a peripheral wall and a plurality of cell storage units; and a plurality of ribs integrally molded with the cell holder between the peripheral wall of the cell holder and the cell storage unit.

An electric vehicle (1) has a battery (2) in an underfloor arrangement. The battery (2) is arranged in a battery space (4) that is delimited by body members (5, 6, 7, 8) of a body (3). The battery space (4) also is delimited at a bottom side of the electric vehicle (1) by way of a protective plate (9). The battery (2) has a connection element (10, 11) at least on a side oriented toward one of the body members (7, 8), and the body member (7, 8) has a recess (12, 13) in which the connection element (10, 11) is arranged.

A vehicle of an embodiment includes a driving device including a rotating electric machine, a case configured to accommodate the rotating electric machine and a PCU that is disposed on a side opposite to a side at which a load is input when the vehicle collides with an object, that is disposed in front of the case and that is configured to supply electric power to the rotating electric machine, a support section that is provided in the driving device and that is configured to come in contact with a vehicle body frame of the vehicle, and an impact attenuating section that is provided on the support section and that is configured to attenuate an impact when the vehicle collides with an object.

A bottom structure for an electric vehicle including at least a first and second beam-shaped battery modules extending in a length direction. Each module is formed by a number interconnected cells and has two longitudinal sides, two transverse sides and a top side covered by a cover plate. The modules are mutually interconnected along their longitudinal sides via an adhesive.

A cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to control electric power supply to the motor; a motor control device configured to control the motor via the motor drive circuit; a switching element arranged on an electric power supply path to the motor drive circuit; a switch circuit arranged separately from the motor control device and configured to switch the switching element between a conduction state and a non-conduction state; and an operation member arranged on the cart and configured to be operated by a user. The cart may operate in a manual mode in which the motor is driven when the operation member is on and the motor is stopped when the operation member is off, and in an automatic mode in which the motor is driven regardless of whether the operation member is on or off.

A cart may include a driving wheel, a motor configured to rotate the driving wheel, a motor drive circuit configured to drive the motor, a motor brake circuit configured to electrically brake the motor, a control device configured to control the motor via the motor drive circuit and the motor brake circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed, and a temperature sensor configured to detect a temperature of the motor brake circuit. The control device may be configured to change the upper limit travelling speed to a second upper limit travelling speed lower than the first upper limit travelling speed when the upper limit travelling speed is a first upper limit travelling speed and the temperature detected by the temperature sensor exceeds a first predetermined temperature.

A battery assembly for an electric vehicle includes two spaced-apart longitudinal profiles extending in a length direction L, interconnected to a front and a rear transverse beam. At least three beam shaped battery modules are interconnected along their longitudinal sides via a plate-shaped interconnecting member, and extend in the length direction, to be attached to an inner surface of the front transverse beam via a bracket. Each battery module is provided with cooling channels extending in the length direction L and having an inlet situated between a transverse end face of the module and the inner surface of the front transverse beam. A water inlet duct extends from an external side the front transverse beam in a central area situated between the brackets, for connecting to a coolant inlet of the central battery module.

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.
