Since the advent of electric mobility, there has been a need for compact, robust, and reliable high-performance connection interfaces to transfer power in the most efficient manner from the charger through the battery pack to the inverter and drive motors. However, the transmission of this critical power presents a unique set of challenges. For example, the ability to reliably handle high power surges during swift acceleration throughout the lifetime of the vehicle, while ensuring an optimum component design in terms of compact and flexible packaging geometry, weight and cost. With the HC-STAK 25 interconnection system, TE Connectivity has developed a new terminal and connector system that is both scalable and capable of reliable high-power distribution to each aggregate throughout the lifetime of the vehicle.
TE Connectivity’s most recent high-voltage (HV) terminal and connector system, the HC-STAK interconnection system, is specifically designed to provide a safe and reliable connection between the HV battery and inverter or the power distribution and e-motor.
With a voltage rating of up to 1,000 VDC and a current carrying capability of up to 257 A at 85°C with 50 mm2 wire the HC-STAK 25 interconnection system represents a high-performance connection system that is both scalable and capable of reliable high-power distribution to each aggregate. An innovative double-ended fork terminal system provides a low contact resistance arrangement while meeting sealing, shielding, and touch-safe requirements in a compact package designed for electric vehicle (EV) applications. It has the flexibility to interconnect with a wide range of conductor cross-sections, geometry, and materials.
