Abstract: An electric wheeled apparatus comprises a main body, a drive wheel supported by the main body in a rotatable manner, an electric motor configured to apply torque to the drive wheel, a battery holder configured to removably receive a plurality of battery packs, and a circuit unit configured to electrically connect one or more battery packs attached to the battery holder to the motor regardless of a number of battery packs attached to the battery holder.

Abstract: A four-stage power distribution system (100) includes (i) a first stage (110) having an inverter (112) that provides power to a frequency drive (114) and an electric motor (116) controlled by the frequency drive; (ii) a second stage (120) having a flywheel (122) driven by the motor; (iii) a third stage (130) having an alternator (132) driven by the motor (116) and connected to the flywheel, and a rectifier (134) that receives current from the alternator and generates a direct current; and (iv) a fourth stage (140) having a charge control switch (142) that receives power from the rectifier, and a plurality of power storage devices such as batteries (144A-144C). A master control switch (150) controls the charge control switch to transition the plurality of batteries individually between a charging configuration and a load configuration. One or more of the battery(ies) in the load configuration provides power to the inverter.

Abstract: A positioning device includes a battery box having a first connection base and a second connection base on two ends thereof. The first connection base has two first positioning members on two sides thereof. A first fixing base includes a first reception space for receiving the first connection base and the first fixing base is pivotable relative to the first fixing base. A second fixing base is connected to the second positioning portion. The positioning recess guides the positioning members on the first connection base to slide and pivot. The second connection base is connected to the second fixing base. The battery box is easily taken out and installed.

Abstract: An electric bicycle and electric bicycle frame including batteries stored in a pair of substantially parallel top tubes. In some cases, the top tubes extend rearward of the bicycle seat tube, and an electronics housing may be disposed between the rearward extending top tube portions.

Abstract: The invention relates to an electric vehicle, especially an industrial truck comprising at least one securing brace (28) for a battery block (24) that is accommodated in the vehicle (10). The securing brace (28) encompasses an engaging section (30) that can be inserted into a first frame part (34) of the vehicle (10), a fastening element (38, 56) that can be hooked into a second frame part (40), and a retaining section (44) that extends therebetween. A supporting section (70) of the securing brace (28) at least partly rests against the battery block (24) in a securing position in which the securing brace (28) is inserted in the vehicle.

Abstract: A system and method for use with a vehicle battery pack having a number of individual battery cells, such as a lithium-ion battery commonly used in hybrid electric vehicles. In one embodiment, the method evaluates individual battery cells within a vehicle battery pack in order to obtain accurate estimates regarding their average transient voltage effect, open circuit voltage (OCVCell) and/or state of charge (SOCCell) so that a cell balancing process can be performed. These cell evaluations may be performed fairly soon after the vehicle is turned off and in a manner that utilizes a minimal amount of in-vehicle resources.

Abstract: The invention is directed to a foldable electric bicycle with power assist having a front portion attached to a rear portion via a central pivot post. The front portion maintains a steering column, handle bar system and a front wheel assembly having a front wheel and an electric power train. The rear portion includes a rear connecting arm to maintain the rear wheel. The central pivot post includes a first end that connects with the front portion and a second end which connects with the rear portion. A peddle assembly connects below the central pivot post and communicates with the rear wheel through a drive chain. A rechargeable battery capable of providing electricity to the electric power train is shaped to fit within a cavity and is located within the central pivot post. The rechargeable battery is positioned proximate the user so as to vertically align with the user's girth.

Abstract: A powered cycle vehicle having an adjustable mounting system for a power unit is described. A power unit is attached to a wheel mounting bracket which is affixed to the vehicle frame and carries the cycle wheel. The wheel mounting bracket may be a unitary structure that defines a wheel mount location and a power unit mount location. Adjustment of the power unit can be made independently of adjustment of the cycle wheel.
