1.5 Charging Stages Introduction
As one of the charging stages, MPPT can not be used alone, but has to be used
together with boost charging, floating charging, equalizing charging, etc. to
complete charging the battery. A complete charging process includes: fast
Current decreases with dwindling light
Open-circuit voltage decreases with dwindling light
With temperature dropping, current
stays stable and power increases
Open-circuit voltage decreases with rising temperature
