Ennovi presents contacting system for prismatic battery cells
According to Ennovi, the contacting system, called CellConnect-Prism, will enable the integration of individual prismatic cells to create larger battery modules or extended cell-to-pack and cell-to-chassis configurations. “By streamlining the assembly process and eliminating inefficiencies, Ennovi-CellConnect-Prism accelerates battery pack production while optimising material usage and reducing costs,” the company writes in a press release.
One of the most important innovations is the use of a die-cut circuit (FDC) as an alternative to the conventional flexible printed circuit (FPC). The process reduces production time and costs and also minimises the environmental impact. In addition, the use of automotive-grade PET material and a special soldering process should ensure optimum heat resistance and component attachment. Voltage and temperature measurements are integrated directly into the assembly.
“Traditionally, prismatic cell contacting systems have relied on current collector assembly (CCA) technologies, which often suffer from inherent inefficiencies,” said Randy Tan, Product Portfolio Director, Battery Platform Development Solutions at Ennovi. “These systems entail complex processes, including laminating and assembling carriers with low-voltage data collection circuits, current collectors, and terminal busbars. However, ENNOVI-CellConnect-Prism revolutionises this approach by introducing innovative features that enhance performance and sustainability.”
Ennovi was only formed in October 2023 through a spin-off from Blackstone’s portfolio company Interplex and will focus on battery, power and signalling solutions for the next generation of electric vehicles. The company is headquartered in Singapore and claims to employ more than 7,000 people across 15 locations.
