Problems solved by technology
The structure of the body of traditional electric vehicles is diverse. Considering factors such as choosing different types of chassis structures or choosing different styles of seats, the shape of the body floor is also various. However, as an electric vehicle, there is no one car that can be used as a whole. The main reason for the layout of the platform floor and batteries is that the battery layout space of electric vehicles is limited, often occupying the space under the front and rear seats or in the middle aisle. The overall platform layout of the floor will leave no place for batteries

Embodiment 1
[0021] Such as Figure 1-3 As shown, the present invention is a battery pack and its installation method. The battery pack 1 is formed by clamping several battery packs 2. The battery pack 2 is composed of several single-cell batteries placed inside the aluminum alloy cavity 3. The aluminum alloy The outer walls on both sides of the alloy cavity 3 are respectively provided with grooves 4 and ribs 5 that can be engaged with each other, and adjacent battery packs 2 are engaged with the integrated battery pack 1 through the grooves 4 and ribs 5 .
[0022] Such as Figure 4-5 As shown, the battery pack 1 is installed on the body floor of the electric vehicle as a platform, specifically: the battery pack 1 is installed in each space separated by the frame beam 6 and the frame longitudinal beam 7, and the height of the battery pack 1 is It is consistent with the height of each space separated by the vehicle frame beam 6 and the longitudinal beam 7 .
[0023] The aluminum alloy cas...

The invention relates to a battery pack and a mounting mode thereof. According to the adopted technical scheme, the battery pack is formed by a plurality of battery groups in clamping connection; each battery group is composed of a plurality of single batteries which are placed at the interior of an aluminum alloy cavity; a groove and a convex rib which are connected in a clamping manner are respectively formed in two lateral outer walls of the aluminum alloy cavity; and adjacent battery groups are integrated into the battery pack through clamping connection of the grooves and the convex ribs. According to the mounting mode of the battery pack, the battery pack is mounted on a vehicle body floor of an electric vehicle in a platform manner. The battery pack and the mounting mode thereof have the advantages that the battery pack is simple in structure, strong in anti-impact resistance and long in service life, and the space in the vehicle can be fully utilized and a relatively good appearance effect is obtained as the platform type mounting mode of the battery pack is adopted.
Description
technical field [0001] The invention relates to a battery pack, in particular to a battery pack for an electric vehicle. [0002] The invention also relates to the installation method of the battery pack. Background technique [0003] The battery pack for electric vehicles is based on the load requirements of electric vehicles. It consists of multiple single cells or super capacitors connected in series and parallel to form a module, and then multiple modules are connected in series and parallel to form a battery pack with a certain voltage and capacity, which is placed inside a sealed box. A battery pack is formed. The structure of the body of traditional electric vehicles is diverse. Considering factors such as choosing different types of chassis structures or choosing different styles of seats, the shape of the body floor is also various. However, as an electric vehicle, there is no one car that can be used as a whole. The main reason for the platform floor and battery ...
