VOSS Automotive, Amphenol-Tuchel Electronics and the GG Group have launched a high-voltage EV charging harness designed to help charging energy as much as 1 megawatt. The brand new system integrates energetic liquid cooling all through the charging cable and socket to scale back thermal losses and allow considerably greater present hundreds. The businesses declare this might cut back cost occasions to underneath 5 minutes.
The charging harness incorporates a number of key parts: the Power2Flow charging cable from GG Group, the CHARGESOK CCS2 socket from Amphenol and a fluid-cooled battery connection and thermal administration system developed by VOSS. On the core is a polymer warmth exchanger embedded throughout the cable, which makes use of a multi-layer plastic tube to flow into a cooling medium—both water-glycol or immersion fluids—between the battery and the charging inlet. The inside layer of the tube is electrically conductive, whereas the outer layer is thermally conductive and electrically insulating.
By actively cooling the areas of peak thermal load, such because the DC contact chambers within the socket, the system avoids overheating with out rising conductor measurement. This strategy permits a 70 p.c enhance in present load capability whereas decreasing cable cross-section, enhancing flexibility and simplifying set up. In distinction to standard options that use massive busbars, this light-weight cable design helps simpler integration into compact EV architectures.
The CHARGESOK socket makes use of direct-contact liquid cooling to dissipate warmth on the supply. A coolant circulates across the high-current contacts, enhancing effectivity and enabling steady high-power charging. The cooling system is designed for compatibility with current automobile thermal architectures, providing flexibility for various OEM platforms.
The system is focused at next-generation EVs requiring speedy cost capabilities and scalable thermal efficiency. The companions emphasize its applicability throughout numerous cooling media, light-weight design, and ease of integration into fashionable automobile layouts.
