A bicycle with removable battery for supplying power to electric components, comprising a frame composed of an upper tube connected with a front oblique tube and with a rear vertical tube, which in turn are connected in a lower region so as to form a seat for a bottom bracket and with which a pair of horizontal rear chainstays and a pair of oblique rear chainstays are coupled. The front oblique tube has an axial seat for a removable battery and for accommodating connection and/or electric power supply cables. The axial seat has an axis that passes above the bottom bracket and a lower end that is open and located at the interspace between the pair of horizontal rear chainstays.

A battery holder is formed separately from a frame of a human-powered vehicle. The battery holder comprises a battery attachment portion and at least one drive unit connection portion. A battery unit is configured to be attached to the battery attachment portion by a threaded member in a removable manner. The at least one drive unit connection portion is configured to be connected to a drive unit that rotatably supports a crank axle of the human-powered vehicle.

A bicycle comprises front and rear wheels, a frame supported on the front and rear wheels and including a frame mount, and a battery including a battery mount engaged with the frame mount. One of the battery mount and the frame mount includes a depression and the other of the battery mount and the frame mount includes a boss positioned in the depression. Preferably, depression comprises a slot, and the slot can include a resilient material to securely hold the boss. The boss can comprise an eccentric boss. Preferably, the battery mount is positioned adjacent one end of the battery, and an opposite end of the battery includes an opening. In this embodiment, the bicycle further comprises a mounting pin positioned through the opening and through a portion of the frame to secure the opposite end of the battery to the frame.

A holding device for releasably holding an energy store at a frame unit, in particular, at a bicycle frame. The holding device includes at least one carrier unit and a stop unit connected to a carrier element of the carrier unit. The holding device includes a tensioning unit, which is provided to fix the energy store at the carrier unit in a tensioned operating state and to clamp the energy store between the tensioning unit and the stop unit in an operating position in such a way that the tensioning unit in the tensioned operating state exerts a pressure force on the energy store, which acts in the direction of the stop unit, in particular, parallel to a longitudinal direction of the carrier element.

An electric vehicle comprises an electric motor for generating driving power for moving a vehicle body of the electric vehicle; a battery unit for supplying electric power to the electric motor; a charging connector connected to an outside electric power supply for supplying the electric power to be charged; a main controller for controlling switching between a first connection state in which the battery unit is connected to the electric motor and a second connection state in which the battery unit is connected to the charging connector; and a relay for opening and closing a power supply path from the low-voltage battery to the main controller; wherein a relay opens the power supply path to cut off electric power supply to the main controller for a specified time, when the relay switches one of the first connection state and the second connection state to the other connection state.

An electric vehicle comprises a cylinder lock including an operation key which is movable by a user's operation between a driving position and a charging position provided at a position different from the driving position and an output unit for outputting information indicative of a position of the operation key; and a main controller permits driving control and inhibits charging control when the operation key is moved to the driving position; and the main controller permits the charging control and inhibits the driving control when the operation key is moved to the charging position.

A battery pack includes non-parallel longer and shorter axes. A virtual first plane includes the shorter axis and an end surface of the battery pack, a virtual second plane includes the longer axis and another end surface of the battery pack, and a virtual third plane is perpendicular or substantially perpendicular to the longer axis and includes the center of gravity of the battery pack. The battery pack includes first and second grips, respectively at least partially located in the first and second planes. The first grip allows the battery pack to be carried such that the longer axis extends in the vertical direction. The second grip allows the battery pack to slide along the first plane. The first grip and at least a portion of the second grip are located on the same side with respect to the third plane.

A frame for an electric vehicle (10) comprising: a head pipe (12) and at least two rear tubes (13) extending rearwardly from the head pipe (12); an electric battery module (24) used as a power source for powering the electric vehicle comprising at least one battery located below rear portion (13B) of said rear tubes (13); a protective frame structure (23) for securely mounting said battery module (24); wherein said protective frame structure (23) is fixed to said rear tubes (13) of said frame and provided substantially centrally and downwardly of said vehicle (10).
