Mechanical and electrical assembly bench test box, automotive environment testing machine

With the vigorous development of new energy vehicles, the reliability of new energy vehicles has received strong attention from the market and has become the technological core of competition among major new energy vehicle manufacturers.Bench testing is one of the automotive inspection projects, especially the critical testing part of powertrain components, which is of utmost importance. Bench testing refers to the process of conducting certain simulated bench tests, including engine tests, before a product can be put into use. At present, most bench tests are conducted under standard atmospheric conditions. However, due to changes in the surrounding environment during the lifespan of automobiles, especially in high-altitude, extremely cold, and hot regionsAdverse environments can cause problems in components such as automotive powertrains that cannot be detected by standard atmospheric conditions. Therefore, it has also attracted more attention from automobile manufacturers.
