Technical Field

[0001] The utility model relates to the field of electric vehicle battery installation, in particular to an electric vehicle battery installation structure. Background Art

[0002] The installation structure of electric vehicle batteries is mainly composed of cell units, which are composed of positive electrodes, negative electrodes, electrolytes and shells. They are the basic components of power batteries. These units are combined into battery modules through parallel and series connection to improve the overall capacity and voltage. Usually, these high-voltage battery packs are installed at the bottom of the vehicle to maximize the use of space and reduce the occupancy of the passenger compartment.

[0003] The batteries used in existing electric vehicles are usually composed of multiple batteries. However, when multiple batteries are connected in parallel, circuit lines need to be used to connect them. However, the current circuit lines are directly placed inside the box where the batteries are installed, which can easily cause collisions between the circuit lines and the battery box. Such collisions may not only damage the circuit lines, causing battery connection interruptions or short circuits, but may also cause short circuits, fires, or even explosions inside the battery box, posing a serious threat to the safety of the vehicle and its occupants. In addition, the exposure of the circuit lines may also lead to unnecessary loss of battery energy, affecting the range and performance of the electric vehicle. Therefore, a safer and more stable battery connection and installation method is urgently needed to ensure the safe operation and stable performance of electric vehicles. Utility Model Content
