Explains what trickle charging is, contains some basic trickle charging circuits.
you no longer need to view a battery as a power-generating element whose characteristics are beyond your knowledge
Li-ion batteries pack the most power per unit volume, but excessive charging or discharging can damage or destroy the battery and its surroundings, carefully designed circuits help you avoid such dire outcomes.
This is a simulation of a simple DC power supply based on a full-wave rectifier. This power supply uses center-tapped transformer and two diodes. This type of circuit is also known as a biphase rectifier.
We often get puzzled by announcements of new batteries that are said to offer very high energy densities, deliver 1000 charge/discharge cycle and are paper-thin. Are they real? Perhaps - but not in one and the same battery.
