Battery case is an important structural component of new energy power batteries. It is mainly used to carry battery system components such as battery modules and cooling systems to protect the battery from damage when it is impacted and squeezed by the outside world. In order to ensure the safety performance of the battery case, it needs to be designed and considered from many aspects.
First of all, the battery case should have various safety protection measures such as overcharge protection, over-discharge protection, and short-circuit protection to ensure that the battery will not be damaged or safety accidents occur during use. These protection measures can be achieved by using high-precision sensors, reliable circuit design, and complete control algorithms.
Secondly, the material selection of the Battery case is also crucial. Materials with flame retardant and high temperature resistance should be selected to reduce the risk of fire. At the same time, the structural design of the Battery case also needs to fully consider its heat and air insulation properties to prevent thermal runaway of the battery during operation.
In addition, the carrying capacity of the battery case is also one of the important indicators of safety performance. It needs to have sufficient strength and rigidity to bear the weight of components such as battery modules and resist external shock and vibration. At the same time, the installation method of the Battery case also needs to consider its stability and reliability to ensure that the battery will not shift or fall off during use.
Finally, the safety performance of the Battery case still needs to go through a series of tests and verifications. For example, safety performance tests such as overcharge, over-discharge, and short circuit need to be carried out to ensure that the battery case can effectively protect the battery from damage in actual use. At the same time, environmental adaptability testing is also required to ensure that the battery case can maintain the stability of its safety performance under different environmental conditions.
To sum up, in order to ensure the safety performance of the battery case, it needs to be designed and considered from many aspects, including safety protection measures, material selection, structural design, load-bearing capacity, installation method, testing and verification, etc. Only in this way can we ensure that the battery case can effectively protect the battery from damage in actual use and ensure the safety performance of the entire power battery system.
