1.4 Introduction of Charging Stages
As a stage of charging, MPPT cannot be used separately, but must be combined
with charging modes such as boost charging, floating charging and equalizing
charging to complete battery charging together. A complete charging process
includes: fast charging, maintaining charging and floating charging. The charging
curve is as follows:
Temperature reduces, current remains constant,
and power increases
