A lifting device capable of releasably holding the power battery module (20) and lifting the power battery module (20) from a ground proximity position on or near the ground to the predetermined installation position is installed at the electric vehicle. As the electric vehicle (10) is provided with the lifting device, installation and removal of the power battery thereof can be accomplished without using other installation equipment. Furthermore, the detachable power battery module (20) can be moved by a user without excessive effort.

A battery attaching/detaching structure for a saddle-type vehicle including: a plurality of substantially rectangular parallelepiped batteries for supplying electric power to a power source of the saddle-type vehicle; a battery case in which the batteries are stored; battery-side terminals provided on lower surfaces of the batteries; and case-side terminals engaged with the battery-side terminals, comprises terminal holders that support the case-side terminals such that the case-side terminals are movable between a connected position where the case-side terminals are connected to the battery-side terminals and a retracted position where the case-side terminals are separated from the battery-side terminals. Between the case-side terminals and the terminal holders, springs for urging the case-side terminals in a direction of pressing the battery-side terminals are disposed. Such battery attaching/detaching structure is capable of limiting the movement of a stored battery and maintaining good electrical connection between a battery-side terminal and a case-side terminal.

Systems and methods for replacing one or more battery modules of a battery pack include using one or more communication devices to instruct a battery management system of the battery pack that a number of battery modules of the battery pack is equal to a remaining number of battery modules in the battery pack after one or more battery modules have been disconnected. The remaining battery modules of the battery pack may be charged to any voltage within a nominal voltage range while the one or more communication devices are coupled to the battery pack.

An electric work vehicle includes a plurality of battery mounting portions, a plurality of battery packs that can be detachably mounted to the battery mounting portions, a main body contact provided for each one of the battery mounting portions and electrically connected with the battery back mounted to the battery mounting portion, a power feeding circuit to which the main body contact is parallel connected, a battery switch configured to block flow of electric power from the battery pack to the power feeding circuit, a switch operating portion for operating the battery switch, a charged amount estimating portion for estimating a charged power of the battery pack mounted to the battery mounting portion, an electric motor driven by power fed from at least one battery pack via the power feeding circuit, and a driving wheel receiving power transmitted from the electric motor.

The disclosure provides a battery replacement mechanism configured to pick and place a battery from and in a first accommodation bay. The first accommodation bay is provided with a first latch to hold the battery therein. The battery replacement mechanism includes a multi-axial slide table assembly, a carrier, and a pick-and-place device. The carrier is movably disposed on the multi-axial slide table assembly, and the pick-and-place device is movably disposed on the carrier. The carrier includes a second latch, and the pick-and-place device includes a catching hook. The second latch is configured to release the first latch of the first accommodation bay, so that the battery may enter and exit the first accommodation bay, and the catching hook is connected to the battery and is configured to drag the battery toward and away from the carrier. The disclosure further provides a battery replacement system and a battery replacement method for a UAV.

A system and method for mobilizing batteries of a vehicle to increase efficiency, performance, and safety is provided. The system generally comprises a battery, frame, track, drive, processor, and non-transitory computer-readable medium having instructions stored thereon. The system may calculate position data and manipulate the battery's position within the frame using the position data. A computing device having position data stored therein may be used by a user to change the position of the batteries. Alternatively, the system may use at least one sensor to obtain environmental data, which the system may use to generate position data and manipulate the position of the battery in real time.

A battery system for an electric motor vehicle comprises first and second battery cartridges that are installed in corresponding first and second battery compartments of the electric motor vehicle. The first battery cartridge has a power connector port with at least one of a shape, size, configuration and orientation that is different than the corresponding power connector port of the second battery cartridge. The first and second battery compartments are physically spaced apart and electrically coupled together by a bridging power cable. The bridging power cable comprises first and second connector ends that extend respectively into the first and second battery compartments, and the first connector end mates more easily with the first power connector port than with the second power connector port, and the second connector end mates more easily with the second power connector port than with the first power connector port.

Battery swapping equipment for an electric vehicle and a positioning method for battery swapping equipment. The battery swapping equipment includes: an unlocking mechanism configured to unlock a battery pack locked onto a fast swapping bracket of the electric vehicle; an image collection module to collect a first actual image containing the lock base during an unlocking process of the battery pack; a storage module configured to store a first standard image collected by the image collection module when the battery swapping equipment is located in a battery swapping position, the first standard image including the lock base; a positioning judgement module to judge whether the battery swapping equipment is located in the battery swapping position according to the first actual image and the first standard image; if not, generating a first moving instruction according to a judged result; a moving mechanism to move according to the first moving instruction.
