Lithium iron phosphate battery charging problem

1. Lithium iron phosphate batteries have a protective plate, but they are mainly used in series circuits. Generally, the protection plate is only used for 3 series.

2. The load should not depend on the circuit. Protection shield. Generally, the overdischarge and overcharge setting range of the protection board exceeds the normal use range of the battery. The function of the protection panel is only to prevent an explosion ~

3. Lithium. Iron phosphate requires a special charger, but is usually better. The lithium battery charger will have a lithium iron phosphate transfer switch 4. The constant voltage power supply in LM317 is absolutely not suitable for lithium charging. the battery is charged at a constant current. The direct charging voltage of 3.2 V is too high. It is very likely that the battery charging currentis exceeded.

5. The charging cut-off voltage of lithium iron phosphate is 3.6V, 3.2V is the rated voltage, and 2.5V is the rated discharge cut-off voltage. The safety of lithium iron phosphate batteries is. better than that of ordinary lithium-ion batteries. Overcharge Overdischarge usually does not explode, so single-cell batteries rarely have protective plates~

Never use constant voltage to apply directly. 3.6 V to the lithium battery at the start of charging. The internal resistance of the lithium battery Small, directly charging the voltage of 3.6V, it is almost disconnected from the power supply. The voltage across 317 will definitely drop, making it impossible. charge. To ensure the voltage of 3.6V, the power supply capacity needs to be increased, and lithium batteries cannot support it~~ Play with Vo lithium battery chargersYou will know that during constant current charging, the difference between the supply voltage and the actual voltage. the battery voltage is very low, generally not higher than 0.5V.

Overdischarge or overcharge of all lithium batteries in the world will cause irreversible crystallization lithium compounds inside the battery. Simply put, the battery is discarded and the only solution is to do so. to replace itCell.

Lithium batteries do not have a “memory effect” like nickel-chromium batteries. Basically what we see a lot now are 18650 lithium batteries which are also a type of lithium battery and won't be. used for a long time, then you will find that the battery cannot be charged. This is caused by over-discharging, meaning the battery voltage has increased.tee lower than the battery discharge cut-off voltage, which is generally. about 2.5V for ordinary lithium batteries.

The conductive coating is also called pre-coating. In the lithium battery industry, it generally refers to a layer of conductive coating covered on the surface of the positive electrode current collector-aluminum foil covered with aluminum foil. The conductive coating is called pre-coated aluminum foil or simply coated aluminum foil. Conductive coatings can effectively improve the adhesion of pole pieces in lithium batteries, reduce the amount of binder used, and also significantly improve the electrical performance of the battery. Its first experiences in the field of batteries date back to the 1970s. With the development of the new energy industry, in particular the development of batteriesries with lithium iron phosphate, they have become a new technology or a new material very popular in the industry.
