An electrified vehicle include a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, an electric motor supported by the chassis, and a trailer coupled to a rear end of the chassis and configured to be towed by the electrified vehicle. The electric motor is configured to drive at least one of the front axle, the rear axle, or a component of the electrified vehicle. The trailer includes a trailer frame, a trailer axle coupled to the trailer frame, and an energy storage device supported by the trailer frame. The energy storage device includes a plurality of batteries. The energy storage device configured to power the electric motor.

In an electrified vehicle, such as a battery electric vehicle, those with a hybrid powertrain, range extended electric vehicles, or hydrogen powered vehicles, integration of the battery may mean that space is very constrained. Typically this means that there is no feasible method to lift the battery to disengage it from the vehicle or to operate any engagement catches or locks etc. The disclosure provides a roller arrangement which has no translation or actuator requirements in order to allow the battery to have reduced frictional engagement with the battery compartment during installation or removal, and also to be well engaged with the battery compartment once installed. Rollers are provided which drop into recesses in the battery compartment at which point they are removed from load bearing engagement and thus, the recesses serve to locate the battery into the installed state in the compartment.

Provided is electric power equipment that allows a battery to be installed and removed with ease. The electric power equipment (1) includes a main body (2) defining a battery receiving recess (40) having an open upper end, and a battery (20) configured to be received in the battery receiving recess, wherein an upper part of a front end part of the battery is provided with a projection (108) projecting in a forward direction, and a rear end part of the battery is provided with a grip, and wherein an upper edge of the front end part of the battery receiving recess is provided with a supporting surface (36) configured to support a lower surface of the projection at least when the battery is being removed from the battery receiving recess.

A battery for a vehicle having a fixed battery pack and a replaceable battery pack. The replaceable battery pack has electronic or mechanical locks to semi-temporarily hold the replaceable battery pack in place. The fixed battery pack is held in place via permanent or semi-permanent fasteners such as bolts. A battery controller controls the replaceable battery pack to power motors of the vehicle before controlling the fixed battery pack to power motors of the vehicle.

A riding lawn mower comprising, a pair of rear drive wheels, a pair of front wheels, a deck positioned between the pair of front wheels and the pair of rear drive wheels, a rotatable cutting blade, and multiple battery packs removably coupled to the riding lawn mower and structured to provide power to the riding lawn mower, each battery pack graspable and removable by a user, wherein the multiple battery packs sequentially provide power to the riding lawn mower.

A vehicle battery pack case includes a battery bolt provided on a lateral side of a vehicle frame; a first nut provided outside the battery bolt, externally and internally formed with an internal screw thread and an external screw thread, of which tightening directions are opposite to each other, and tightened to the battery bolt through the internal screw thread; and a second nut provided outside the battery bolt and the first nut, and tightened to the first nut through the external screw thread formed on the first nut.

A solar-powered vehicle that includes a body having opposing sides and defining a cavity; two or more wheels; a first and second solar panel assembly respectively disposed on the opposing sides of the body; one or more electric motor disposed within the cavity of the body between the first and second solar panel assemblies, the one or more electric motors configured to rotate at least one of the two or more wheels; and one or more electric battery disposed within the cavity of the body between the first and second solar panel assemblies, the one or more electric batteries configured to power the one or more electric motors and to be charged by electric current generated by the first and second solar panel assemblies.

A battery pack maneuvering system for a vehicle with a fifth wheel that includes a battery pack and an actuator. The battery pack is provided with a fifth wheel coupling member that removably couples the battery pack to a fifth wheel of a vehicle. The actuator is mounted onto the vehicle, removably couples to the battery pack, and lifts the battery pack to remove the battery pack from the fifth wheel.

The invention belongs to the field of new energy vehicles, and particularly provides a locking and unlocking fixture capable of adaptive position adjustment. The invention aims to solve the problems of existing automated unlocking apparatuses for traction batteries having high requirements for machining precision, and the resulting machining difficulties. The locking and unlocking fixture of the invention comprises: a fixture sleeve, a base sheathed inside the fixture sleeve, and a first spring provided between the fixture sleeve and the base, wherein a clearance fit is formed between the fixture sleeve and the base, and the fixture sleeve can move vertically relative to the base, such that the fixture sleeve can match a locking device of the power battery even if there is a certain positioning error when the fixture sleeve is engaged with the locking device, and the fixture sleeve can return to an initial position under the action of the first spring when the fixture sleeve is disengaged from the locking device of the power battery. As a result, it is not necessary for the locking and unlocking fixture of the invention to provide high-precision machining and installation to enable an automated unlocking apparatus to successfully unlock the power battery.

A battery device of an electric bicycle includes a battery, a battery mount which allows attachment/detachment of the battery, a stepped portion, and a restriction release in a first end of the battery, and an engaging portion and a second movement restrictor in a first support of the battery mount. The engaging portion is restricted in its movement, by the second movement restrictor, from an engaged position where it is engaged by the stepped portion to a disengaged position where it is not engaged by the stepped portion. When the battery is to be removed, from the battery mount, the restriction by the second movement restrictor is removed, the restriction release is used to move the engaging portion from the engaged position to the disengaged position, and then the battery is pulled in a removal direction, to remove the battery from the battery mount.
