I am wondering what to do to the secondary coil in order to have enough energy to charge the battery ..
thank you.. ^^
Inductive power transfer is the process of wirelessly transferring electrical energy between two or more objects through the use of electromagnetic induction. This technology is commonly used in charging devices such as smartphones and electric vehicles.
Inductive power transfer works by using an alternating current in a transmitter coil to create a magnetic field. This magnetic field induces a current in a nearby receiver coil, which is then converted into electrical energy to power a device.
Inductive power transfer eliminates the need for physical connections, making it a convenient and safe option for charging devices. It also allows for more flexibility in the design of devices, as they do not need to accommodate for charging ports. Additionally, inductive power transfer is efficient and reduces the risk of overcharging or damaging devices.
One limitation of inductive power transfer is the distance between the transmitter and receiver coils. The further apart they are, the weaker the magnetic field and the less energy that can be transferred. This technology is also less efficient than traditional wired charging methods.
Inductive power transfer is used in a variety of applications, including wireless charging pads for smartphones and electric toothbrushes, electric vehicle charging stations, and even in some medical devices. It is also being researched for potential use in powering electronic devices in remote locations.
