How to Set IC 741 for Auto Cut-oFF
In this post I have explained how to set or adjust an opamp 741 IC based battery charger circuit for implementing an automatic cut-off for the connected battery once it reaches the full-charge level. Since I have many such IC 741 battery charger circuits posted here, the instructions will be helpful for correctly setting up […]
Battery Bank Charger Circuit
The post narrates an automatic Battery Bank charger circuit with an automatic over charge cut-off feature for operating with an electric car. The idea was requested by Mr. George. Circuit Objectives and Requirements I’m George From Australia trying to convert small car into an electric car. The attached PDF show the configuration of lithium battery […]
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 […]
Accumulators Explained [Rechargeable Batteries]
Unlike dry batteries, whose stored electrical energy can only be used once, accumulators have the immense advantage of reversibility, which translates into the possibility of a series of charge/discharge cycles. This means that they can undergo a series of charge/discharge cycles. They are found in applications that may require more power, such as starting the […]
Simple SCR Battery Charger Circuit
In this post I have explained a simple yet accurate SCR triggered battery charger circuit which can be used effectively for charging all types of battery, which includes, lead acid battery, Ni-Cd battery banks, Li-Ion battery, etc. This SCR charger can be seen implemented in most automobile garages, and is very popular among auto mechanics, […]
