6 Frequently Asked Questions about “Battery coupled induction”
What is inductive charging?
Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
What is high power inductive charging?
High power inductive charging generally refers to inductive charging of batteries at power levels above 1 kilowatt. The most prominent application area for high power inductive charging is in support of electric vehicles, where inductive charging provides an automated and cordless alternative to plug-in charging.
How does inductive coupling work?
Inductive coupling works by transmitting energy using two coaxial coils which act as transmitter and receiver, creating thereby a magnetic field. This method involves mutual induction where an AC supply to the transmitter coil creates a magnetic field that in turn produces an output current to a receiver coil.
Does resonant inductive coupling-based wireless power transfer work for deep-cycle Li-ion batteries?
