Constant Voltage, Constant Current Battery Charging There are three common methods of charging a battery; constant voltage, constant current and a combination of constant voltage constant current with or without a smart charging circuit. Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre set voltage. 7.4V Two Step Lithium Battery Charger Circuit CC and CV ... 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 8.2V as discussed. The most common technique used to measure voltage with Microcontrollers like Arduino is by using a Voltage divider circuit . 14. WHY IS CHARGING WITH CCCV BAD? Qnovo Yes, it is a mouthful and it stands for “ constant current constant voltage.” It is presently the charging approach used for lithium ion batteries. As I indicated earlier, it was invented in the 19th century for charging lead acid batteries, and somehow it became the default charging methodology for present day lithium ion batteries. What does CC, CV and dV dt stand for? CC CV refers to a constant current, constant voltage charging algorithm. Most of the charging is accomplished by sending a constant current through the cell. But once a specified voltage is reached, the charging changes to constant voltage to top off the battery. Constant current constant voltage battery charger ...
