Tesla has secured four global patents related to wireless charging technology, covering circuit design, ground leakage prevention, and temperature sensors. Read ahead…
Tesla’s recent patent filings reveal plans for a wireless home EV charging station. This technology could support the company’s vision for autonomous driving, offering a convenient, hands-free charging solution for future Tesla owners.
Patent documents show Tesla’s work on wireless EV charging, a feature that the company has not previously focused on. Tesla has shown little interest in wireless charging for its electric vehicles. The current manual process of plugging in an EV is neither difficult nor time-consuming.
However, as Tesla advances its self-driving technology, automating the charging process seems like a logical next step. Autonomous vehicles that drive themselves could also charge themselves.
In the past, wireless technology was less efficient than cable charging, but newer systems using magnetic resonance claim to have closed the gap, offering up to 95% efficiency.
Interestingly, Tesla had once favored a robotic arm for automatic charging but seems to be shifting towards wireless solutions. Last year, Tesla released an image of a wireless home charging station, although it has not provided further details since.
The company’s lead designer, Franz von Holzhausen, also recently confirmed that Tesla is working on a wireless charging pad. There have been hints that the Cybertruck will include wireless charging capabilities.
Tesla has filed four new patents related to wireless EV charging:
- Shorting Switch to Reduce Ground Leakage Current in Inductive Charging
- Temperature Sensors and Applications in Wireless Charging
- Wireless Charging Circuit Topology and Related Methods of Manufacturing
- Parameter Estimation for Wireless Charging
Although the exact launch date of Tesla’s wireless charging technology is unclear, it may coincide with the unveiling of Tesla’s Robotaxi next month on 10 October. This would align with Tesla’s goal of enabling self-charging for autonomous vehicles.
