Battery Charger Circuits

In this post I have explained how the internal body diodes of MOSFETs could be exploited for enabling the charging of battery through the same transformer which is being used as the inverter transformer. In this article we will investigate a full bridge inverter concept and learn how the in-built diodes of its 4 MOSFETs […]

The precise battery capacity tester circuit explained in the following article can be used for testing the maximum backup capacity of any rechargeable battery in real time. By Timothy John Basic concept The circuit works by practically discharging a fully charged battery under test through constant current, until its voltage reaches the deep discharge value. […]

In this post I have explained many simple NiCd charger circuits with an automatic overcharge protection and a constant current charging. When it comes to correctly charging a Nickel-Cadmium cell, it is strictly recommended that the charging process is halted or cut off as soon as it reaches the full charge level. Not following this […]

If you are an automotive technician, vehicle technician, or a motor mechanic, you may find this cheap yet powerful car battery charger circuit extremely handy, as it can be used for charging all types of car and motorcycle battery overnight with minimum effort. This charger is specially suited for garages since it has a rugged […]

These smart, intelligent battery charger will charge a Li-IOn battery rapidly by monitoring 3 crucial parameters, which are constant current, constant voltage and constant 25 degrees Celsius temperature. The post elaborately explains 3 Hi-End, automatic, advanced, single chip CC/CV or constant current, constant voltage 3.7V Li-Ion battery charger circuits, using specialized Hi-End IC TP4056, IC […]

In this article I have explained how to build an automatic battery charger circuit using dump capacitor concept for self detecting and charging a multiple set of batteries. The idea was requested by Mr. Michael. Circuit Objectives and Requirements My name is Michael and live in Belgium. I found your site thru google during my […]
