Coin Based Universal Mobile Battery Charger
[attachment=68181]
ABSTRACT:-
The coin-based mobile battery charger developed in this paper is providing a unique service to
the rural public where grid power is not available for partial/full daytime and a source of revenue for site
providers. The coin-based mobile battery charger can be quickly and easily installed outside any business
premises. The mobile phone market is a vast industry, and has spread into rural areas as a essential means of
communication.While the urban population use more sophisticated mobiles with good power batteries lasting
for several days, the rural population buy the pre owned mobile phones that require charging frequently. Many
times battery becomes flat in the middle of conversation particularly at inconvenient times when access to a
standard charger isn't possible. The coin-based mobile battery chargers are designed to solve this problem. The
user has to plug the mobile phone into one of the adapters and insert a coin; the phone will then be given a
micro-pulse for charging. It does not bring a mobile from 'dead' to fully charged state. The charging capacity of
the mobile is designed with the help of pre defined values. It is, of course, possible to continue charging the
mobile by inserting more coins. This compact and lightweight product is designed to cater for the growing
number of rural mobile users worldwide. A suitable microcontroller is programmed for all the controlling
applications. The source for charging is obtained from direct power grid and solar energy in case of non
availability of grid power.
. INTRODUCTION
The growth of mobile phone market is phenomenal in recent years and the need for charging the
mobile battery is required anytime and anywhere. In many developing countries the grid power is not available
for few hours to several hours on daily basis especially in semi urban and rural areas where the mobile phones
are the essential communication device. While the urban population use more sophisticated mobiles with good
power batteries lasting for few days, the rural population buy the pre owned mobile phones that require
charging frequently even two or three times a day. In the event of unpredictable grid power and availability of
abundant solar power. a coin based universal mobile battery charger is designed and developed in this paper.
This device is like a vending machine for mobile battery charging at kiosks and the user has to plug the phone
into one of the adapters and insert a coin for charging at a constant current for a definite duration.
The solar power application to battery charging has been studied in the past. Solar chargers convert
light energy into DC current for a range of voltage that can be used for charging the battery. They are generally
portable but can also be firmly mounted. In this design of coin based mobile charger a fixed solar panel of size
635x550x38mm , 37WP is used to charge the battery upto maximum 2 .0 amp in bright sun light.
In this paper, the design and development of a coin based universal mobile battery charger based on
main power and solar power is discussed and this is primarily for rural areas where the mobiles are basic needs
for communication and the main power is not available all the time. The motivation for this research came from
the published papers[1to 3].
CONCLUSION
In this paper, a novel method of charging mobile batteries of different manufacturers using solar power
has been designed and developed for rural and remote areas where the grid power is not available all the time.
The mobile communication has become a necessity even in rural areas and this device is useful for charging
mobile batteries as these mobile battery chargers can be installed in kiosks at various places for the convenience
of mobile users. The final prototype made and tested is shown in Fig.8 and the complete specifications are given
in Table 2
