Product Description
New energy vehicles have been plagued with a range of problems, such as thermal diffusion of battery, functional safety and other safety issues, the consistency among charging pile communication protocols, functional performance verification of motor, and controller accuracy. As a result, manufacturers are facing a variety of challenges. Specifically, the safety of batteries and how to disassemble and recycle old batteries. With the increasingly higher requirements for cell energy density, it is imperative to develop new cells. However, the corresponding testing technology and standard evaluation system are lagging behind and fail to meet the current needs for application and development.
