DESIGN AND CONSTRUCTION OF AN AUTOMATIC BATTERY CHARGER ABC

DESIGN AND CONSTRUCTION OF AN AUTOMATIC BATTERY CHARGER ABC

The practical importance of a battery charging unit in today’s world cannot be over emphasized. This is so since these batteries or accumulators are immensely needed by automobiles and in science laboratories. This thesis describes the methodical approach to the design and construction of any battery changer. However the procedure developed cover the construction of battery charger for battery sizes ranging from 6 volts to 12 volts.

The phototype of a battery charger for these ranges of battery has been implemented following the methodical approach as outlined in this thesis and its operational test results are quite satisfactory.
Adequate care has been taken in the design and construction to ensure that the resultant battery charger is both reliable and easy to use.
