Said device also includes a charge receiver including a secondary coil L2 arranged in a vehicle. Said method consists of adjusting a frequency f of the power supply voltage (E) to the resonance frequency fo, when a motor vehicle is located in a parking space. Said method comprises the following steps: setting a first power-transmission parameter (E, f); starting an iterative test which consists of: setting a value of a second power-transmission parameter (E, f); varying the second power-transmission parameter (E, f) in a second authorized adjustment range; measuring the power (Pbat) transmitted between the charge transmitter and the charge receiver; determining if the power (Pbat) is no lower than a predetermined operating threshold (PObj); determining if the power (Pbat) increases; ending the iterative test if the transmitted power (Pbat) is higher than the predetermined operating threshold (PObj); setting the power supply voltage (E) in order to reach the measured transmitted power (Pbat), said first and second transmission parameters being set to the previously established value thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for charging a vehicle battery by induction","description":"The invention relates to a method for charging a vehicle battery by induction from a charging device including a charge transmitter including a primary coil L1 and an inverter capable of supplying the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9849796","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
