The circuit diagram of the Arduino-controlled 12V automatic battery charger is shown in Fig. 1. It is built around Arduino Uno (Board1), adjustable voltage regulator LM338 (IC1), 12V voltage regulator ...

This document explains the construction of an Arduino based Maximum Power Point Tracking (MPPT) solar charge controller, capable of charging a 2V sealed lead acid battery which can drive the following ...

The main objective of our 12V power supply circuit is to control the voltage and current for the battery so that it can be charged in the best possible way. For this purpose we have used two LM317 ICs ...

Here is a tried and tested sample circuit of a Li-Ion battery charger that can be used to charge any 3.7V Li-Ion battery using a 5VDC (USB, Solar Panel…) power supply. At the heart of the circuit is ...

I found my cheap chinese charge controller used more power over the course of 24hrs than (nominally) 10W solar panel produced. In this project is the code for the Arduino (tested on an R3, but soon to ...

Measuring Lithium Battery Voltage To monitor the charging process we have to measure the battery voltage, only then we can shift the charger from CC mode to CV mode when the battery voltage reaches ...

A charge controller is one of the main components of a solar battery charging system (Fig. 1). Its main function is to fully charge a battery without permitting overcharge or reverse current flow ...

In this paper, a simple method battery charge controller has been designed to protect the battery from over-charging and deep discharges. The control of the process is entrusted to Arduino Uno board, ...
