What is CTS Technology?

CTS is a self-compensating cable that delivers more input power than conventional cables and is the reason our solution is so powerful.

Power distribution through CTS results in far lower voltage drop than traditional Litz cables and enables us to design better, more efficient systems that other wireless providers struggle to do.

How does it Work?

Specifically, CTS enables us to deliver the high-frequency AC electricity (85kHz) used in Wireless Power Transfer (WPT) over long distances. At these frequency levels, reactance becomes the dominant component of the impedance. It is this reactance that CTS significantly reduces and hence why its performance is so superior and unique in WPT applications.

CTS Benefits

A comparison was run on a 100 metres sample of CTS and conventional cable using a stable 50 amp current and 400 volts. Results showed that conventional cable causes the voltage to drop by 65% at 85kHz, whereas CTS only has a 5% voltage drop.

By matching the design of the cable to a particular wireless charging application, the distance constraints associated with conventional cable can be virtually eliminated!

These benefits apply to all wireless EV charging applications, including static, semi-dynamic and dynamic scenarios.

Conventional Cable vs CTS

No Data Found

The voltage drop for a conventional cable at 85kHz is 37% at 20m and more than 95% beyond 150m.

By comparison, CTS at 85kHz experiences only a 5% voltage drop over a similar distance.
