A battery system of a vehicle is provided and includes a battery module assembly (BMA) formed by overlapping a plurality of battery modules along a first direction, a cooling fan installed to be aligned along the first direction on one side of the BMA and configured to discharge air cooling the BMA while passing therethrough, a low voltage battery installed to be aligned along the first direction on the other side of the BMA, a power relay assembly (PRA) aligned along a second direction perpendicular to the first direction and installed adjacent to the low voltage battery, and a battery management system (BMS) aligned along a third direction perpendicular to the first direction and the second direction and installed adjacent to the low voltage battery and the PRA.

A frame structure for maintaining energy storage devices of a vehicle in position which is deformed in a controlled way in the event of a side-impact, in such a way to avoid deforming into the location of the vehicle seats. The proposed frame structure is adapted to deform controllably in a centre position align with a location between the vehicle seats. In this way are occupants of the vehicle kept safe since no or less deformation occur in the vehicle seat location. The above advantages are provided by that lateral support members of the frame includes a deformation zone adapted to deform in response to a lateral force exerted on the lateral support member. The deformation zone is located such that, when the frame structure is installed in the vehicle, the deformation zone is aligned with a location between seats of the vehicle.

A battery tray and a vehicle include a frame structure including a plurality of frames sequentially connected end to end arranged to be connected to the vehicle, and a base plate structure including an inner base plate and a reinforcing beam, wherein the inner base plate is located on an inner side of the reinforcing beam and arranged for mounting a battery module. The battery tray further includes a reinforcing block, wherein the reinforcing block is connected to a corresponding frame and the reinforcing beam in a matching mode, so as to fixedly connect the reinforcing beam to the frame structure through the reinforcing block. In the battery tray, the strength of the battery tray can be enhanced and a total weight can be decreased only by using the reinforcing block to fixedly connect the reinforcing beam to the frame structure.

An exemplary support assembly includes a first housing that supports a first battery structure, a second housing that supports a second battery structure, a cover, and a common attachment that secures together the first housing, the second housing, and the cover. An exemplary support method includes securing together a first housing, a second housing, and a cover with a common attachment. The first housing supports a first battery structure that is enclosed by the second housing. The second housing supports a second battery structure that is enclosed by the cover.

A vehicle battery protection structure includes a vehicle frame member, a first duct, and a second duct. The vehicle frame member is disposed in a region including a battery. The vehicle frame member has a through hole. The battery is mountable on a vehicle. The first duct is disposed on an outside of the battery at a location oriented toward an outside of the vehicle. The second duct is inserted through the through hole of the vehicle frame member. The second duct is disposed to overlap the first duct in a vertical direction of the first duct on the outside of the battery at the location oriented toward the outside of the vehicle.

A battery pack comprises a lower-stage battery stack and an upper-stage battery stack. The upper-stage battery stack is separated from the lower-stage battery stack in a vehicle height direction. A middle frame that is a reinforcing member is arranged at a height position that matches a height position of a separation space between the upper-stage battery stack and the lower-stage battery stack in terms of a position in the vehicle height direction. Longitudinal frames of the middle frame project outward from the upper-stage battery stack in a vehicle width direction.

A battery pack for a vehicle electrical system includes a casing for receiving one or more battery modules. The battery modules are insertable into a casing of the battery pack by sliding couplers along pairs of rails and are securable to the ends of the rails. After insertion, the rails thermally insulate one battery module from other battery modules in the battery pack. Additionally, the battery modules may include a top cover with an insulating material to further thermally insulate one battery module from another battery module. The battery pack may additionally be configured with vents for venting the hot gases, such as those generated by a battery module in a thermal runaway event. Additionally, the battery modules may include a second insulating material disposed between cells and configured to thermally insulate the cells from one another.

A vehicle structure includes a fuel tank configured to store a fuel supplied to an internal-combustion engine of a vehicle and a battery configured to store an electric power supplied to an electric motor of the vehicle to drive the vehicle. A gravity center of the battery is lower than a gravity center of the fuel tank, and at least a part of the fuel tank overlaps with the battery in a top plan view of the vehicle.
