Features and Benefits

Eliminate the need for daisy-chain wiring with FPC connectivity

Our FPC connection is a more reliable solution because it eliminates the human error potential of manually wired connections and it is more resistant to degradation.

Molex provides the FPC signal connector used in the Volfinity system

Manufacturers of products using battery management systems will discover that, as a leading connector manufacturer, Molex is a one-stop shop for interconnect reliability.

The plastic tray in Volfinity Cell Contacting Solutions is relatively lightweight

Designers will find the Volfinity Cell Contacting System doesn’t add much weight to a battery module.

FPC connector:
Sends temperature, voltage and current data to the battery management system

Copper busbar:
Forms the +ve and -ve poles of the battery module. Withstands tightening torque

Uses metal adaptor and laser welding instead of wires and joining method:
Decreases chance of deformation

Aluminum busbar:
Offers thermal efficiency and mechanical flexibility

Plastic tray:
Enhances safety by decreasing risk of arcing

Plastic tray hold components in place and Aluminum busbar connects cells in series or parallel:
Provides easy, fast implementation and reduces labor time. Delivers reliable connectivity

Designed with cover:
Provides safety by preventing contact with electrical current

Available for prismatic and cylindrical cells:
Offers design flexibility

Overview

Volfinity delivers a reliable interface solution that connects cells to the control board in an electric vehicle battery module, eliminating the need for daisy chained wires. The total solution enables integrated cell sensing features, cell monitoring and balancing, and temperature measurement functions, all designed to meet the functional safety requirements of EV manufacturers. 

Designers of electric vehicles (EV) need large, powerful batteries while simultaneously maintaining weight to meet EV requirements. The plastic tray in Volfinity Cell Contacting Systems is relatively lightweight while delivering a reliable connection.

Automotive designers need battery management system connectors in their cell contacting systems and often have to rely on a separate vendor in order to procure them. Because Molex is a connector manufacturer, the FPC signal connector in the Volfinity system comes from the same reliable source.
