How to charge lithium ion batteries?

In order to charge lithium-ion batteries, constant current/constant voltage (CC/CV) is often adopted for high-efficiency charging and sufficient protection.

Could wireless inductive charging revolutionise electric vehicles?

Wireless inductive charging could help popularise electric vehicles (EVs) by making it quicker and easier to top up the battery. If the technology could be installed into roads, it might even be possible to charge EVs as they’re driving, a process known as dynamic charging.

Why is inductive charging better than traditional charging?

Inductive charging has some disadvantages compared to traditional charging. These include a longer charging time due to energy losses, and less freedom to use the phone during the charging process, as the charging process will be halted when the phone is picked up.

Can IPT battery charger charge CC/CV batteries?

However, it is not easy to design an IPT battery charger that can charge the batteries with a CC/CV charge due to the wide range of load variations, because it requires a wide range of variation in its operating frequency, duty, or phase-shift.

How does an inductive charger work?

An inductive charger works based on the principles of electromagnetic induction. A coiled wire inside the charger acts as a transmitting coil. When alternating current flows through it, an electromagnetic field is created.

How does a vehicle drive on an induction loop?

Now a vehicle drives onto the induction loop. In the vehicle's chassis, currents are induced by the alternating field of the loop. These currents form a magnetic field themselves and have a counter-effect on the original field.
