Aluminum Used in Electric Car Battery and Engine

The power battery system (battery pack) is the power source of the whole new energy vehicle and one of the most critical components of electric cars. The battery pack is generally composed of battery modules, electrical systems, thermal management systems, battery management systems and structural parts.

The main function of the battery enclosures is to carry the battery module, electrical module, cooling module and other power battery system components, while protecting the battery and electrical system from damage when they are hit or squeezed by the outside world.

At present, most pure electric vehicles choose steel or aluminum alloy materials as the protective shell of the battery pack to ensure the safety of the chassis power battery. To a large extent, the safety of the power battery can be protected, but it also faces the problem of heavy battery pack, meaningless increase in curb weight, increased power consumption, reduced endurance, and even varying degrees of impact on vehicle handling.

Another key development in battery technology that impacts enclosures is the evolution of the role of the EV battery in the body-in-white. Originally a body-in-white supported component, the battery enclosure is now becoming a structural part of the body-in-white, and automakers are even exploring battery-to-body and structural batteries, where the design of the enclosure can be a key factor.

Aluminum is a very effective cell-to-battery pack solution compared to some other options, with aluminum offering thermal conductivity and weight savings. AA3003 aluminum is used for this purpose.

Aluminum alloy is a common kind of metals used in car engines and transmission system parts, such as engine blocks, crankcases, transmission housings, etc. Aluminum has very good heat dissipation performance, which helps improve the heat dissipation effect of the engine and reduce the overall weight.

6000 series aluminum contains silicon and magnesium, which form magnesium silicide and allow aluminum alloys to be heat treated. They have their own characteristics in appearance and performance and can be used to manufacture parts such as car bodies, engines, seats, etc.

Compared with steel parts, it can reduce weight by 50%. At the same time, aluminum alloy parts have good thermal conductivity, which can effectively ensure the heat dissipation of the engine and also play an important role in meeting the protection of pedestrians in car collisions.
