The fast-growing electromobility market is set to place major new demands simultaneously on the leak testing of batteries. WEH® Test Connectors are well able to face this challenge, having proved themselves already to be the ideal tool for efficient and cost-effective leak testing.
Leak testing forms part of a great many production processes as a quality assurance method. It has proven its effectiveness in many branches of industry, especially when used in monitoring production processes in series manufacturing. Efficiency, quality and speed are key factors in leak testing. These three key elements directly affect a fourth factor: cost.
The advance of the electromobility sector brings with it a range of new requirements for automotive manufacturers. High-voltage batteries are a key component in the industry. As a result, the market for battery testing stations is growing at the same time, as batteries need to be tested for leak tightness both during development and at the end of the production line.
And battery packs in electrical vehicles need to be tested for loss of refrigerant and for leak tightness against fluids. Each individual battery cell has to be effectively protected against atmospheric humidity getting into it and against fluids. Standard test procedures for this purpose include helium and vacuum testing.
