  Battery management system plays an important role for modern battery-powered
application such as Electric vehicles, portable electronic equipment and
storage for renewable energy sources. It also increases the life-cycle of the
battery, battery state and efficiency. Monitoring the state of charge of the
battery is a crucial factor for battery management system. This paper deals
with monitoring the state of charge of the battery along with temperature,
current for Solar panel fitted with battery for residential application.
Microcontroller is used for controlling purpose, analog sensors are used for
sensing the parameters of voltage, current. The information of the battery is
given with tabular form and shown in photograph. Battery parameters are
displayed with the LCD screen.
