Electric vehicles need optimum temperatures (neither warm nor cold) to run safely and efficiently. Temperature is essential for the proper working of the battery pack, power electronic systems, and motor in the electric vehicle. Power electronic systems and motors demostrate their best working state under optimal temperatures. The working temperature of the electric motor is critical to the performance of the vehicle. Therefore, the cooling of the motor is necessary for its full performance in electric vehicles.
LANGAN® LA651 series electric vehicle test connector provides quick, optimized and cost efficient air tightness test solutions for the motor water cooling port.

3. Challenges:
Conventional bore plugs are not only unsuitable for liquid media, but also affects the circulation performance. The connectors should have a cutoff function to avoid residual liquid drop.
4. Solutions:
LA651 series test connector perfectly overcomes all the above challenges.
Jaw locking mechanism is adopted. Push to connect instantly and pull the sleeve to disconnect. And it does not affect the flow capacity of the water outlet. Push to connect instantly and pull the sleeve to disconnect. A build-in shut-off is integrated.
5. Application:
For flowing liquid or air tightness test of cooling water port on Electric Vehicles (EVs) Microprogrammed Control Unit (MCU) and motor housing.
6. How to customize:
Custom leak test connectors for electric vehicle are designed to a specific client's demand to perfectly adapt to testing space, various connection ends and surface conditions with unwavering standard.
