Today's battery-charger subsystems regulate charging voltage and current using the intelligence of an external microcontroller (µC), usually available elsewhere in the system. This approach achieves low cost in high-volume applications and allows the greatest flexibility in tailoring the charger to a specific application.
The battery charge measurement is required to estimate the State of Charge (SoC) of the battery. The PIC16F15276 microcontroller include 10-bit Analog-to-Digital Converter (ADC), Timer, and Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) peripherals which can be used for realizing battery monitoring system application.
The code for the microcontroller will not be that difficult to write. Since the ADC will convert the input voltage to a value between 0 and 1023, a fully charged 12V battery should be near the 1024 value, and this value will decrease as the battery discharges.
Smart batteries, on the other hand, conduct a rich exchange of serial data with the battery pack, usually providing all the necessary charging parameters over a specialized I 2 C-like protocol called the System Management Bus (SMBus ™). Once the charger determines that a cell is installed, it must determine if the cell is good.
Microcontrollers are also a cheap and effective way to accomplish simple tasks like controlling a thermostat, blender, or refrigerator. Monitoring battery life is an important function that needs to be implemented in most applications that use batteries as their power source.
