More recently, portable electronic devices, such as laptops, smart phones, and digital devices, such as digital cameras and camcorders, rely on rechargeable lithium-ion (Li-ion) batteries. It is common knowledge that these batteries must be regularly charged from a wall outlet supply. Alternatively, a futuristic cost-effective and cleaner approach would be to charge these portable device batteries wirelessly. Usage of such a charging infrastructure would mean that the device need not be plugged in every time charging is required. This, therefore, makes the practice truly portable and efficient.
This project will deal with the design of a wireless inductive charger for portable electronic devices. An inductive charging pad will be designed and implemented. The designed charging pad can be used to charge either a cell phone or an iPod (as examples of portable devices). A suitable power electronic converter (charging circuitry/power supply) will be modeled and designed. In addition, a smart battery charging algorithm will need to be incorporated, which should be able to identify the battery chemistry and size. The developed charging algorithm will allow the power electronic converter to charge the battery pack at a safe and appropriate current level. |
