ENNOVI Unveils Innovative Busbar Sealing for EV Solutions

Revolutionizing Busbar Sealing Technology

ENNOVI, a key player in mobility electrification, has unveiled a groundbreaking approach with its innovative busbar sealing technology, designed specifically for electric and hybrid vehicle drivetrains. This state-of-the-art solution, known as ENNOVI-SealTech, eliminates coolant leaks while providing enhanced manufacturing efficiency and design flexibility compared to traditional methods.

Innovative Solutions for Modern Challenges

Managing busbar interfaces in electric vehicles, where coolant is on one side and a dry electrical connection is necessary on the other, presents numerous challenges. Dominik Pawlik, Product Portfolio Director for Power Interconnects at ENNOVI, points out the downsides of conventional sealing methods like potting materials, rubber O-rings, or gaskets, which often involve costly secondary processes and potential leakage issues over time. ENNOVI-SealTech effectively addresses these limitations, bringing a new level of effectiveness to the production process.

Sealing Methodology

The ENNOVI-SealTech offers two innovative sealing methods: double-walled shrink tubes and adhesive tape. Both methods are designed to tackle challenging applications without requiring post-processing, significantly enhancing manufacturing efficiency while ensuring optimal sealing performance. This flexibility positions ENNOVI-SealTech as an adaptable solution for a wide range of design requirements.

Rigorous Testing and Validation

To guarantee the robustness and reliability of the ENNOVI-SealTech technology, each configuration undergoes extensive testing. This includes thermal aging tests at 150°C for 1,000 hours and thermal shock cycling from -40°C to +150°C for up to 600 cycles, conforming to the stringent EN 60068-2 standard. A leak test is also conducted to ensure the integrity of the seal, reinforcing ENNOVI's commitment to delivering quality solutions.

Versatile Compatibility

One of the standout features of ENNOVI-SealTech is its compatibility with a variety of shapes and materials. The use of shrink tubing or tape allows the technology to adapt seamlessly to different busbar designs and specifications. It works effectively with an array of materials, including metals like copper (Cu) and aluminum (Al), as well as various plastics such as PA66, PBT, and PC, positioned to meet the diverse needs of the automotive sector.
