This battery pack is formed by a sandwich construction, which is divided into multiple subdivisions as the waterproof housing and the battery housing. The battery frame is made of lightweight aluminium, which provides a lot of installation space for the cells and increases the battery capacity .
Then, the air is conducted in the battery pack for the thermal management; Active technique: part of the exhausted air is brought to the inlet and mixed with new fluid from the atmosphere. Then, the heat exchanger cools down or heats the fluid to reach the optimal temperature for battery pack management.
Regarding future developments and perspectives of research, a novel concept of thermal management of battery packs is presented by static devices such as Thermoelectric Modules (TEMs). TEMs are lightweight, noiseless, and compact active thermal components able to convert electricity into thermal energy through the Peltier effect.
The thermal spreading interval between the thermal runaway battery and the neighboring batteries in the module is increased to an infinite length, and only the thermal runaway battery shows the phenomenon of spraying valve such as fire and smoke. It is expected to have a guidance for the design of thermal insulation in lithium-ion battery modules.
A hot environmental temperature can trigger the battery to accelerate the redox chemical reactions, which directly causes an abundance of heat generation (thermal event). In the long run, the phenomenon can cause thermal runaway in the battery. For subtropical climates, EVs require a heating system to ensure the battery does not freeze.
The battery frame is made of lightweight aluminium, which provides a lot of installation space for the cells and increases the battery capacity . These characteristics permitted the manufacturer to insert 33 modules of 12 individual cells each, which can store a gross amount of energy equal to 93,4 kWh.
