Tesla’s Wireless Charging Breakthrough: Efficiency Surpasses 90%, Redefining The Future Of Electric Vehicles

Tesla has made a remarkable announcement, declaring that its wireless charging efficiency is astonishingly "over 90%!" This statement has shaken the industry, addressing the doubts surrounding the efficiency of wireless charging systems. Recently, according to foreign media reports, Tesla has responded positively to questions about its wireless charging system for the autonomous taxi, Cybercab, claiming that its charging efficiency is "far higher than 90%."

This statement was made on October 19th. Prior to this, the well-known tech reviewer Marques Brownlee (MKBHD) pointed out on social media that wireless charging systems suffer from "huge thermal energy waste" and believed that the "ideal target" for wireless charging of electric vehicles could only reach "about 75% efficiency." However, Tesla's response shattered this perspective, clearly stating that their wireless charging system's efficiency "far exceeds 90%", which surprised Brownlee into posting an "amazed eyes" emoji. Encouraged by another user, Brownlee said, "I accept the correction and look forward to the launch of this product."

Earlier this month, at the "We, Robot" event, Tesla's CEO Elon Musk announced that the newly released Cybercab would use inductive charging technology for wireless charging, as opposed to the traditional NACS interface. This news garnered considerable attention at the time.

Although wireless charging technology plays a significant role in Tesla's future plans for autonomous taxis, it was not until the "We, Robot" event that the company first publicly demonstrated this system. During the event, Tesla also showcased a Cybercab charging at a rate of 19kW while at a 35% state of charge (SoC), far surpassing the approximately 11.5kW charging power provided by the Wall Connector.

It is worth noting that there were speculations in the past that Tesla might have already entered the field of wireless charging for electric vehicles last year. At that time, Tesla acquired the wireless charging company Wiferion. Although Tesla later sold Wiferion, it retained some of the engineers who joined through the acquisition. Today, Tesla's breakthrough in wireless charging technology has undoubtedly injected new vitality into the development of the electric vehicle industry.
