An efficient and embedded battery charger controller is the important part in the electrical charging and protection systems which used to charge the rechargeable batteries. Most of the chargers are not efficient, due to the way of their integration and charging monitoring
process due to not availability of LCD to display the voltage and current status of the load
and battery, as well as they do not provide a protection for the batteries against
overcharging, discharging, high cost and inaccurate. The implementation of battery
charger controller techniques on an embedded system application based solar panel is a
new technique and very important aspect. So, the design is simulated by Proteus
simulation software, and then prototype circuit is set up. The programing software in the
design which was developed by Micro C language. The designed device consists of a
charger circuit which performs charging, LCD to display the battery charging voltage
level, load current / voltage, sensors to sense the load voltage and current as well as the
battery instant voltage. The PIC16F877A Microcontroller was used as the main
component to control and manage all charging and discharging events in the circuit as
well as to provide protection of battery against over and under voltage level. The
modeling of analog to digital converter (ADC) was used in the PIC to measure the voltage
level of the battery and load voltage and current. The alarm LEDs fires on were used in
this design for over load and over charging. The embedded battery charger controller was
developed to be more intelligent based on suitable DC source and used to charge and
control up to five batteries with different capacities. Each battery was individually
controlled by a synchronization of two PICs microcontrollers and another PIC was used
to control on the batteries temperature. All the three LCDs were used to indicate the
batteries voltage, load voltage, load current and batteries temperature. The switching
amplifier transistors were controlled by PICs via OR gates to control the operation of
relays to protect the batteries against overcharging, discharging and the temperature that
produced during the charging process. The alarm system circuit was designed and
programmed in both of synchronized PICs to alarm when the overcurrent is occurred at
the load. LEDs were also used for each battery in this circuit to indicate when each battery
is fully charged. The efficiency of the circuit was 85%. As well as, the results were
collected from the simulation and implementation of the circuit and plotted for explaining
