ENNOVI Introduces Cutting-Edge Busbar Sealing Technology

ENNOVI, an industry leader in mobility electrification solutions, has launched a pioneering sealing technology for busbars that promises to transform hybrid and electric vehicle (EV) drive systems. Known as ENNOVI-SealTech, this patented innovation aims to prevent coolant leaks, thus enhancing both manufacturing efficiency and design versatility compared to traditional methods.

The Need for Advanced Sealing Solutions

Mike Thompson, Director of Engineering at ENNOVI, highlights the complexity of managing busbar interfaces in EVs, where one side must handle coolant while maintaining a dry, electrically robust connection on the other. Traditional sealing methods, such as potting compounds and rubber O-rings, often incur high costs and time-consuming secondary processes. They also pose a risk of leaks over the product's lifespan. ENNOVI-SealTech addresses these challenges effectively.

Versatile Sealing Methods

The new ENNOVI-SealTech offers two sealing methods—dual-wall heat-shrink tubing and adhesive tape—designed for demanding applications. Importantly, both options eliminate the need for post-processing, significantly enhancing manufacturing efficiency and design flexibility without compromising sealing integrity. This versatility ensures that ENNOVI-SealTech can accommodate nearly any busbar shape or construction.

Rigorous Testing Regimen

To guarantee the technology meets stringent design requirements, ENNOVI-SealTech undergoes exhaustive testing procedures. Each configuration is subjected to thermal aging tests at 150°C for 1,000 hours, and thermal shock cycles ranging from -40°C to +150°C for 600 cycles, based on the EN 60068-2 standard. A comprehensive leak test ensures the sealing's integrity, confirming the reliability of this advanced technology.

Compatibility Across Materials

Moreover, ENNOVI-SealTech is compatible with a broad spectrum of metals and plastics, including copper, aluminum, and various polymers. This adaptability broadens the range of applications, making it ideal for use in motors, inverters, and oil pump interfaces within EVs and hybrids.
