Lithium iron phosphate battery charging method
Lithium rechargeable batteries have been widely used. Lithium iron phosphate batteries have many advantages because of their unique advantages. The charger for lithium iron phosphate battery is different from ordinary lithium battery. The maximum termination charging voltage of a lithium battery is 4.2 volts; the lithium iron phosphate battery is 3.65 volts (there is a maximum of 3.8 volts on the Internet), and the question now is: Can you use the charger of the mobile phone (slightly modified)? Charging the lithium iron phosphate battery; or using a scrapped lithium battery protection circuit board (slightly modified) for charging protection of lithium iron phosphate battery.
When charging, it is the cable that balances the charging board. Generally, the whole charging is directly connected in series from both ends, and the charger voltage is greater than the voltage of the battery pack. The cable detects the voltage of each cell, which is equivalent to a parallel voltage regulator. The cell charging voltage does not exceed the regulation value, while the other cells continue to be charged and bypassed by the Zener diode. Because the charge of each cell is almost full at this time, just balancing each cell, so the charging current is small, and the balance is filled with each cell. The charger can only protect the voltage of the entire battery pack. The balance of the charging board is to ensure that each unit is overcharged and each unit is full. It cannot stop charging the entire battery pack because one of the batteries is full.
