A bicycle including a frame that has a head tube, and a frame member that is elongated along a longitudinal axis. The bicycle also includes a receiver that is disposed in the frame member, and a battery pack that is coupled to the frame member and detachably connected to the receiver.

Battery pack and electric vehicle including the same

A battery pack and an electric vehicle including the battery pack, the battery pack including a battery, the battery including at least one battery cell that is rechargeable and dischargeable, wherein the battery supplies power to a load; a controller configured to control an amount of power to be used by the load; and a battery manager configured to measure a remaining capacity of the battery and to provide information about the measured remaining capacity to the controller.. .

Method and battery management

The present disclosure is related to a battery management system which includes a location information obtainer configured to obtain location information of a battery, and an estimation model changer configured to change an estimation model to estimate an internal state of the battery according to a change in the location information.. .

Method and system for charging an electric vehicle

A method of positioning an electric vehicle, such as a battery electric vehicle, plug-in hybrid electric vehicle, or similar vehicle relative to a charging point includes receiving at the vehicle a global positioning system (gps) signal, receiving at the vehicle a global positioning system correction signal, correcting the global positioning system signal using the global positioning system correction signal, and positioning the vehicle relative to the charging point using the corrected global positioning system signal such that the vehicle can be charged by the charging point.. .
