Introduce the charging skills of lithium iron phosphate batteries

How to charge lithium iron phosphate batteries The full name of lithium iron phosphate batteries is lithium iron phosphate batteries. Because its performance is particularly suitable for power applications, the word power was added to its name, that is, lithium iron phosphate power lithium battery. It is also called lithium iron battery, lithium iron phosphate, do you know how to charge it? Here is an introduction to the charging techniques of lithium iron phosphate battery. It is recommended that lithium iron phosphate batteries adopt the CCCV charging method of constant current first and then constant voltage. A constant current of 0.3c is recommended. Recommendation 3.65. When the battery voltage reaches 3.65v, use 3.65v voltage and constant voltage charging. When the charging current is lower than 0.1c (or 0.05c), the battery is fully charged. When you use a balanced voltage power supply to charge, you should also check the charging current. It is recommended not to charge with an excessively high voltage. After adjusting the voltage, make sure that the charging current is less than 0.5c, which is good for the battery. The general upper limit of the lithium iron phosphate battery voltage is 3.7~4V, and the discharge threshold voltage is 2~2.5V. Considering the discharge capacity, discharge voltage, charging time, constant current capacity percentage, safety, five aspects, use constant current and constant voltage Charging method, lithium iron phosphate battery pack, charge reasonable limit set voltage 3.55V to 3.70V, recommended value of 3.60~3.65V, discharge threshold voltage is 2.2V to 2.5V. The lithium iron phosphate battery pack charger is different from ordinary lithium ion batteries. The maximum termination voltage of lithium ion batteries is 4.2 volts; the lithium iron phosphate battery pack is 3.65 volts. When charging a lithium iron phosphate battery, the balance charging board is connected to the circuit, and the overall charging is generally directly connected in series from both ends, and the charger voltage is greater than the battery voltage. The online detection of the voltage of each unit is equivalent to a parallel voltage regulator. The charging voltage of a single battery will not exceed the regulated value, while other single batteries will continue to be charged through the regulated bypass. At this time, the power of a single battery of the lithium iron phosphate battery is close to saturation, and only each battery is balanced. Therefore, the charging current is very small and each battery is fully balanced. The charger can only protect the end voltage of the entire battery pack. The balanced charging board can ensure that each unit is fully charged and each unit is full. Therefore, the charging of the entire lithium-ion battery pack cannot be stopped because the battery is full.
