PROJECT MANAGEMENT
Title: Wireless Mobile Charger
Introduction
Wireless mobile charger is a recent trend by which the mobile phones can be charged
wirelessly. One of the major advantages of this technology is that, the wireless chargers are
compatible with the mobile phones from any manufacturer. It works on a principle of inductive
charging and makes use of a resonant inductive coupling between the charging station and the
mobile device that is to be charged [5]. Wireless mobile charger can be developed to achieve a
cable free docking station for all cellular devices. This will help in charging the device anytime,
anywhere. The project aims at designing, implementing and launching a wireless mobile charger
that would be compatible with every mobile device.
Project Background
A wireless mobile charger allows a user to charge his/her mobile phone wirelessly. This
can be done without plugging the mobile adapter. The wireless mobile charging system makes
use of a charging pad, where the mobile phone is placed in order to charge the phone. An
advanced power-transferring concept is used for the system [1]. The major hardware
specifications that are needed to the project include HF- transformer, capacitors, voltage
regulator, USB connector and rectifier. With this system, the wireless power transfer occurs
through the process of electromagnetic induction. In wireless charging system the power is
transferred to mobile devices not through the traditional cable but wirelessly. The system makes
use of an electromagnetic field in transmission of energy to the mobile phone. It eliminates the
need of plugging a cable into the smart phone in order to charge it. Wireless charger that is to be
designed will provide a faster charging in comparison to the charging via cable [7]. An

electromagnetic field helps in transferring the energy from the charger to a phone. This project is
undertaken in order to provide convenient charging experience and to facilitate a more robust
connection [8].
Project Goals
The major goal of the project is to design a wireless charging system to provide fast and
convenient charging to every smartphone. The project aims at developing a system that will
eliminate the need of plugging in a cable in order to charge a smartphone. Furthermore, the
project aims at developing a system that will provide a faster charging speed in comparison with
the wired charging, which is not the case for the existing wireless chargers. Apart from this, the
system will be designed in such a way that the phone does not heat up and can be charged even
with the back cover on [4]. The objectives of the project are as follows-
Project Objectives
The main objective of a wireless mobile charger is to charge a mobile battery wirelessly.
The charging will start automatically when the phone comes in contact with the wireless charger.
The project objectives are [2]-
1. To determine the functional and non functional requirements of the project
2. To schedule the project on basis of the identified requirements
3. To develop the circuit of the wireless charging system
4. To implement the project
5. To launch the wireless mobile charger

of the project is an important consideration, as it will help in eliminating any bugs present in the
system before launching the product.
Project Requirements
Functional Requirements
The functional requirements identified for development of a wireless mobile charger are
as follows-
1. Considering the transfer distance of wireless charging is an essential functional
requirement of the project.
2. The power level and charging speed is the main functional requirement of this project

PROJECT MANAGEMENT
3. Apart from the above two major functional requirements, spatial freedom or the
accuracy with which the mobile phone is to be placed on the charger is a functional requirement
of the project as well.
Non-Functional Requirements
The non-functional requirements identified for development of a wireless mobile charger
are as follows [6]-
1. Ensuring proper safety of the system is a major non-functional requirement of the
system. It also adds to the efficiency and reliability of the system.
2. Consideration of Radio frequency interference or RFI
3. Efficiency of power transfer to the mobile device
4. Cost of implementation
These are the major functional and non-functional requirements of the project that is
needed to be considered for developing a wireless mobile charger.
