How to arrange the lithium battery pack system on electric vehicles?

① It is necessary to arrange more power in the limited space as much as possible, so as to achieve a greater cruising range and reduce the frequency of charging. Any space that can be used is conducive to the increase of the power of electric vehicles. ②It is necessary to fully consider the impact of the position of the lithium battery pack on the safety performance of electric vehicles, especially in extreme situations such as collisions, rolls, and drops, will the lithium battery pack be deformed due to great acceleration or severe extrusion? Fire and explosion, or whether parts of the lithium battery pack enter the passenger compartment, causing additional injuries. ③It is necessary to fully consider the impact of the weight and shape of the lithium battery pack on the structural life of the vehicle, because the weight of the lithium battery pack usually reaches hundreds of kilograms, which brings great static and dynamic loads to the chassis and suspension of electric vehicles. Under long-term vibration and shock conditions, it is easy to cause fatigue damage to the mechanical parts of the electric vehicle and reduce the life. ④The heat dissipation conditions of the lithium battery pack must be fully considered, especially under high temperature working conditions and high electrical load working conditions, a large amount of heat will appear in the lithium battery pack. If the heat dissipation conditions are not ideal or close to the heat source, the life of the lithium battery pack will be accelerated. attenuation. ⑤The installation position of the lithium battery pack in the electric vehicle will also affect the axle load distribution and the center of gravity of the electric vehicle, which in turn affects the driving experience and comfort of the electric vehicle. The most external shape of the automobile power lithium battery pack should meet the requirements of the vehicle installation space, and the installation and maintenance of the battery pack should be considered during the design. The installation position of the lithium battery pack should consider impact, vibration, rollover, etc., and the box should be able to withstand a certain degree of impact. The space left for the battery pack varies from model to model, and the design of the lithium battery pack must be combined with the design of the vehicle. The inside of the lithium battery pack should be conducive to the arrangement and installation of the battery modules, and the shape of the lithium battery pack should be compatible with the layout of the battery modules.
