Battery-Discharge Protection for Appliances on the Move
However, the voltage drop across the diode when forward biased leads to a reduced charging voltage being delivered to the battery, resulting in undesired power dissipation. A diode rectifier with a typical forward voltage V F =0.55V carrying a 3A charging current would dissipate 1.65W (P=I x V F ).
Fundamentals of battery charging: Part 1
Once the battery voltage reaches its float voltage level (in most modern batteries this is 4.2 V), charging enters the constant voltage phase and charge current starts diminishing. In theory, the battery cell is not fully charged until the cell voltage is 4.2 V with very little current going into the battery, which would mean that the voltage drop …
