3.7V Lithium Polymer Battery

　　The most suitable charging process for 3.7V Lithium Polymer Battery

　　To reduce the safety accidents of lithium batteries, you must choose the appropriate charging method. Without understanding the lithium battery charging process, you cannot properly use lithium batteries. The most suitable lithium ion battery charging process can be divided into: trickle charging , constant current source battery charging, constant current source battery charging and battery charging complete.

　　1. Trickle charging: Precharge the fully charged and discharged rechargeable battery. When the battery voltage is less than 3V, use a larger DC circuit to charge the lithium battery.

　　2. Constant current charging: When the battery voltage rises above the trickle charging threshold, constant current charging is carried out by increasing the current. The constant current charging current is close to the middle, and the linear charging head design , will always rise as the battery voltage rises to minimize the heat dissipation of the transmission transistor.

　　3. Constant voltage battery charging: When the battery voltage rises and the constant current power supply battery is charged, the constant current power supply battery charging process begins. In order to achieve the best performance, the voltage regulator tube tolerance should exceed +1%.

　　4. Battery charging stops: Unlike nickel rechargeable batteries, continuous trickle charging of lithium batteries is not recommended. Continuous trickle charging of metallic lithium can cause pole plate plating process effects. This will cause the battery to become unstable and may cause sudden automatic breakdown.

　　In order to deal with the possible safety risks of 3C lithium batteries, we can start from the source. First, improve the safety factor of metal electrodes and lithium battery electrolytes to avoid direct contact between metal electrodes and lithium battery electrolytes, thereby improving the reliability of rechargeable batteries. safety; the second is to improve the safety protection design of 3C lithium batteries. It is necessary to install battery protection panels, and you can also use heat-sealing diaphragms, set battery valves, and improve protection circuits and thermal fuses to improve The safety factor of rechargeable batteries; third, the use of high-current spring leaf micro-needle beauty control modules makes battery detection more efficient, and is also beneficial to the reliability of 3C lithium battery detection. The strong current spring leaf microneedle beauty mold can bear a strong current of 50A, has a stable and reliable connection, has excellent adaptability to small and medium-sized particles, has an average service life of more than 20w times, and is highly compatible with 3C lithium battery testing.
