INTRODUCTION
1.6 CHARGING STAGES
Maximum power point tracking is used to charge the batteries with the highest current possible, but this is only part of the
equation. A battery cannot be charged at maximum power all the time for safety reasons, so multiple stages are used.
These stages include bulk, boost, oat and, for some types of batteries, equalization as shown in Figure 1-6.
