Overview

Radio and television metrology can provide a one-stop integrated solution for environmental adaptability, reliability, functional performance, and other aspects of new energy vehicles and components, promoting the upgrading of the quality level of the new energy vehicle industry.

Product Details

Safety issues such as thermal diffusion and functional safety of power batteries, consistency of communication protocols at charging stations, verification of motor functional performance, and controller accuracy are seriously troubling new energy enterprises. Manufacturers face many challenges, such as the safety of power batteries and how to dismantle and recycle old batteries. With the increasing demand for battery energy density, the development of new system batteries is imperative. However, the corresponding testing technology and standard evaluation system for new system batteries are lagging behind and cannot meet the current application development needs.
