ENNOVI Unveils Advanced Busbar Sealing Technology for Electric and Hybrid Vehicles

ENNOVI, a prominent partner in electrification and mobility solutions, has recently announced an innovative technology designed to improve the sealing of busbars within the drivetrains of electric and hybrid vehicles. This cutting-edge solution, known as ENNOVI-SealTech, prevents coolant leaks and offers enhanced manufacturing efficiency along with greater design flexibility compared to traditional methods.

Understanding the challenges in managing interfaces within electric vehicles (EVs) is crucial. These vehicles necessitate a connection that remains dry and electrically robust on one side while managing coolant effectively on the other. Dominik Pawlik, the Product Portfolio Manager for Power Interconnections at ENNOVI, emphasizes that conventional sealing techniques, such as encapsulation and the use of rubber O-rings, can lead to excessive costs and delays during assembly. Moreover, these methods may create leakage problems over the product's lifespan. ENNOVI-SealTech effectively addresses these issues, leading the way for more reliable, long-lasting designs.

Advanced Sealing Solutions

The ENNOVI-SealTech technology offers two specific sealing methods: dual-wall heat shrink tubing and adhesive tapes, suitable for challenging applications. Both methods eliminate the need for secondary processing, significantly enhancing manufacturing efficiency while maintaining superior sealing performance.

Each product configuration undergoes rigorous testing to ensure compliance with the specific requirements established for various designs. The testing process includes comprehensive assessments such as thermal aging at 150°C for 1000 hours and thermal shock cycling from -40°C to +150°C for 600 cycles, adhering to the EN 60068-2 standard. A sealing integrity test is also conducted to confirm the robustness of the seal.

Furthermore, the versatility of ENNOVI-SealTech allows it to adapt to a broad range of busbar shapes and design specifications. Its compatibility with various materials, including copper (Cu), aluminum (Al), and several types of plastics like PA66, PBT, and PC, makes it an ideal solution for diverse applications within the space of electric mobility.
