Gel Cell Battery Charger Circuit [Constant Current, Constant Voltage]
In this post I have explained what are gel cell batteries and also learn how to build a specialized charger for charging a gel cell battery, with full calculations. The proposed circuit works in two modes: it starts charging a discharged gel cell battery with constant current, until the full charge voltage is reached across […]
Smart Buck-Boost MPPT Solar Charger Circuit for 12V 24V Battery
In this post we are going to learn how we can make one real working smart solar battery charger circuit which can do MPPT charging. We are using Arduino Nano as the brain for controlling everything. We will also use INA219 sensor module so that we can read the solar voltage and current properly. And […]
Make this EV Battery Charger Circuit
In this post I will explain how to build and test a homemade yet very professional looking high power EV battery charger transmitter circuit using H-bridge fixed-frequency AC inverter topology, driving a series-resonant LC tank. I will also explain how to build a complementing EV charger receiver circuit for receiving the charging current from the […]
Wireless Li-Ion Battery Charger Circuit
Charging batteries through inductive wireless charging is one of the applications that’s becoming very popular and getting appreciated by the uses. Here we’ll study how to make a wireless Li-Ion battery charger circuit using the same concept. Any electrical system which involves wire networks or cables can be very messy and cumbersome. Introduction Today the […]
