The present disclosure relates to a battery system for a hybrid or an electric vehicle. Another aspect of the present disclosure provides a battery assembly designed for easy and quick exchange of battery assemblies enabling a vehicle to resume driving much more quickly than traditional charging permits.

A battery assembly for installation into a battery structural space of a transportation vehicle body having a battery housing accommodating a number of battery modules, wherein the battery housing has a smaller dimension along a vehicle longitudinal direction than the battery structural space, such that a free space is formed in the battery structural space, and wherein a shear panel element is provided as an areal bridging and stiffening of the free space.

Disclosed herein is a quick-change universal power battery for a new energy vehicle. A battery body is provided with a quick-change connection port, a recessed structure, an independent liquid temperature-control loop and a multi-connection port structure. The battery body is provided with a recessed area, and the quick-change connection port is arranged in the recessed area. A power battery system is composed of no more than eight main models of quick-change universal power batteries to achieve battery selection and replacement of most new energy vehicles, and the power battery system is combined with charging to facilitate an electrical-energy supplement of the new energy vehicle. A vehicle and a replacement station are also disclosed.

Disclosed are a battery swapping station and a control method therefor. The battery swapping station comprises: a first charging compartment and a second charging compartment; a first battery swapping platform, and a control unit, the control unit being electrically connected to the first shuttle and to the second shuttle, used for controlling the first shuttle and the second shuttle to perform the following operation: when operating a same vehicle on the first battery swapping platform, if the first shuttle is executing either operation of battery unmounting or battery mounting, the second shuttle executes the other operation of battery unmounting or battery mounting. The battery swapping station and the control method therefor, by means of alternating operations of the first shuttle and the second shuttle, reduces the waiting time for vehicles when swapping batteries, thus increasing the battery swapping efficiency of the battery swapping station.

The present disclosure relates to energy storage mounting system for an energy storage system of a vehicle, the mounting system comprising: a vehicle mounting member connectable to a longitudinal frame of the vehicle, the vehicle mounting member comprising an elongated portion arranged to, when the vehicle mounting member is attached to the longitudinal frame, extend away from the longitudinal frame, wherein the elongated portion comprises a recess at an outer end portion thereof; and a battery mounting member connectable to the energy storage system, the battery mounting member comprising a connecting portion, wherein the connecting portion is movable between a disconnected state, in which the connecting portion is positioned at a distance from the elongated portion of the vehicle mounting member, and a connected state, in which the connecting portion is positioned in the recess for connecting the battery mounting member to the vehicle mounting member.

Provided is a battery swap type hybrid power vehicle (100). The hybrid power vehicle (100) comprises a range extending type driving system formed of a range extender (10) and a driving motor (31), and further comprises a quick-swap battery (20) which can be quickly disassembled and swapped in a battery swap station. The quick-swap battery (20) is connected to the driving motor (31) to form a battery swap type driving system. The battery swap type driving system and the range extending type driving system can be quickly switched and independently serve as a main power system. The range extending type driving system taking the range extender (10) as a power source and/or the battery swap type driving system taking the quick-swap battery (20) as the power source can be freely and flexibly switched according to a use scene and economy to drive the vehicle to travel.

A locking method and an unlocking method are provided. The locking method is used to mount a battery to a fixing seat of an electric vehicle by a locking device. The locking device includes: a lock base including a lock body, a surface of the lock body being provided with a lock groove recessed towards the interior of the lock body, the lock body being internally provided with a lock tongue groove and a lock tongue movably mounted in the lock tongue groove, and the lock tongue groove being in communication with the lock groove; and a lock shaft including a shaft rod configured to be inserted into the lock groove of the lock base to perform unlocking and locking.

A locking device includes a lock base configured to provide a locking position, and including a lock body having a surface provided with a lock groove recessed towards the inside of the lock body, the lock body being provided with a lock tongue groove and a lock tongue movably mounted in the lock tongue groove that is communicated with the lock groove; and a lock connecting rod movably connected with the lock base through the lock tongue, and including a rod member configured to drive the lock tongue to move under the action of an external force, the rod member being provided with an unlocking block on a side facing the lock base, and the unlocking block being configured as an arc protrusion formed outwardly by the rod member.

A battery pack and an electric vehicle are provided. A plurality of lock shafts are mounted on an outer side of the battery pack, and each of the lock shafts includes a shaft seat and a shaft rod. The lock shaft is mounted to the outer side of the battery pack by the shaft seat. A concave positioning hole is arranged at an end of the shaft rod away from the shaft seat, and a first positioning steel magnet is mounted in the positioning hole.

An energy store-floor assembly for a motor vehicle includes an electrical energy storage device that has a plurality of battery modules and that is accommodated in a multipart storage housing and arranged on the underside of a vehicle floor of the motor vehicle. In order to provide an energy store-floor assembly for a motor vehicle in which the energy storage device is connected to the motor vehicle bodyshell in an improved manner, the battery modules of the energy storage device are connected to the vehicle floor in a central region of the storage housing by way of a plurality of mechanical connecting elements.
