A battery tray for supporting batteries at a lower portion of a vehicle frame includes a floor plate and a perimeter wall disposed around the of the floor plate to substantially surround a containment area for storing vehicle battery cells. The perimeter wall includes a tubular member that extends along a periphery of the floor plate to form a perimeter wall around a containment area for storing vehicle battery cells. The perimeter wall is attached at an upper surface of the floor plate, such that the containment area may be generally bounded horizontally by the perimeter wall and at the bottom by the floor plate.

Disclosed is a battery swapping system, comprising a battery swapping device, a signal transmission unit, a position sensor, and a detection section. The battery swapping device comprises a master control unit and a battery pack disassembly and assembly unit. The battery pack disassembly and assembly unit is used for clamping the battery pack, the master control unit is used for controlling the battery pack disassembly and assembly unit to move along a preset path. The position sensor is used for generating a stopping instruction upon sensing of the detection section, sending the stopping instruction to the master control unit which is used for stopping moving the battery pack disassembly and assembly unit according to the stopping instruction. According to the present invention, whether a battery pack is mounted in place can be accurately detected, the accuracy and safety of battery pack swapping is ensured and the costs are low.

A vehicle body includes an energy source frame with a mounting system. The mounting system includes a mounting portion of the energy source frame extending along at least one side of the energy source frame and a sleeve with a first end and a second end. The mounting portion comprises an opening extending vertically through the mounting portion, and the opening comprises an entrance with a first dimension and a base with a rim and a second dimension. The second dimension is smaller than the first dimension. The sleeve is positioned through the opening with the first end sitting on the rim of the base and the second end extending vertically above the entrance.

Battery exchange system for an electric vehicle, comprising: a battery unit; a battery receiving unit adapted for being fixed at or near a bottom surface of an electric vehicle and comprising a housing with an opening at a bottom side of housing for at least partially receiving the battery unit in the housing through the opening, wherein the battery receiving unit has a central axis which extends through the opening; wherein the battery receiving unit is adapted for allowing movement of the battery unit along its central axis between an unmounted position below the battery receiving unit and a mounted position at least partially within the battery receiving unit, wherein the battery unit comprises first engagement elements and the battery receiving unit comprises second engagement elements, each of the first and second engagement elements being adapted for engaging each other while moving relative to each other along an associated sloping path in order to lift the battery unit from the unmounted position to the mounted position or lower the battery unit from the mounted position to the unmounted position, wherein said associated sloping path slopes with respect to a plane normal to the central axis.

A battery tray for supporting batteries at a lower portion of a vehicle frame includes a floor plate and a perimeter wall disposed around the of the floor plate to substantially surround a containment area for storing vehicle battery cells. The perimeter wall includes a tubular member that extends along a periphery of the floor plate to form a perimeter wall around a containment area for storing vehicle battery cells. The perimeter wall is attached at an upper surface of the floor plate, such that the containment area may be generally bounded horizontally by the perimeter wall and at the bottom by the floor plate.

A covering of an outer sill of a vehicle, in particular a motor vehicle, has a covering region and a mounting region, which extend between first and second ends of the covering along a direction of longitudinal extension. The mounting region extends in a first direction of transverse extension perpendicular to the direction of longitudinal extension and has mounting elements in order to be able to be mounted on an underside of the outer sill for a mounted state. The mounting region has a lateral edge facing away from the covering region in the direction of longitudinal extension, which has recesses between mounting elements, which are formed such that sections of the lateral edge of the mounting region extend in a recessed manner in the first direction of transverse extension towards the covering region.

A high voltage battery carrier for a vehicle includes: a main carrier coupled to a vehicle body frame and fixed to a high voltage battery; a subcarrier coupled to an upper portion or a lower portion of the main carrier and configured to form a space in which an electrical and electronic part is accommodated when coupled to the main carrier; and a detachable carrier which is vertically detachably installed on the subcarrier. The electrical and electronic part is coupled to the detachable carrier. With this arrangement, installation space can be reduced and workability is improved due to easy attachment and detachment of the electrical and electronic part.

A battery pack attachment assembly includes, among other things, a first bracket configured to be secured directly to a vehicle underbody, and a second bracket. The first bracket extends vertically above the first bracket such that the second bracket is spaced from the vehicle underbody when the first bracket is secured directly to the vehicle underbody.

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 system can prevent burning of a vehicle or human injury caused by a fire spread from a battery to a vehicle in the event of a fire in the battery of an eco-friendly vehicle. The system can release a battery from the vehicle such that the battery can be separated and removed from the vehicle when a fire occurs in the battery. The system is operated in response to a control signal of a controller detecting the fire in the battery and by manipulation of a driver, and releases a state of the battery mounted to a vehicle body to release the battery from the vehicle such that the battery can be separated or removed from the vehicle.
