Li-ion battery multi-stage charger with power factor correction for mobile phone - Essay Example

ase of implementing the circuit into hardware would be reduced; thus, enabling the introduction of a multiprocessor to control the battery’s charging process (Liu, 2013.p.108-112). By adopting this multi-stage charger, it would be largely expected that appropriate rectifications would be made to the current designs of Li-ion batteries in a manner that would enable users attain total satisfaction from their use. The proposed multi-stage charger would use a diode in the smoothening of the transition between two high-gain linear feedback loops.

This would enable it to control the single power device; hence, enable automatic charging of the battery under constant current and voltage (Andreini & Murari, 2002.p.335-341). The main components that would be required for the enhancement of this project for a single isolated configuration of the system would include micro-controllers, temperature regulators and sensors, lead acid and LCD batteries, resistors, ADC and an op amps integrator for the circuits. However, to be able to achieve the goals or this project as far as the acquisition of the gadgets or above noted items and the project’s cost, an approximate total amount of $200 would be required to cater for the budgetary allocations on the same.

I hope that this project and related concepts will be concluded by the close of this present semester. In the contemporary world of these days where the use of electronic gadgets is at a higher rate, the main concern of consumers is on the durability of the battery cells that they apply to their devices whether mobile phones, laptops, iPods, among many other such devices. For a long time, the manufacturers of such gadgets have engaged the use of Lithium-ion batteries in the provision of a much needed energy to power the devices.

The main concern for the choice of usage for the Li-ion batteries is the accuracy, compactness and power efficiency of the battery’s charger circuits. In order to build up a power factor
