In addition to high voltage charging, constant voltage charging, constant current charging. Intelligent charging: This is the ideal charging management method. It follows the charging algorithm mentioned at the beginning of this section and is integrated in a small SMD IC. The peripheral circuit is simple, stable and reliable, such as TP4054/4055/4056/4057 , TP4002/5000, MAX1879, etc.
The main feature of this chip is that it will monitor the voltage and current at the same time when judging whether it is full, stop charging at 4.2V, or stop charging when the charging current is less than 0.01C (usually about 50mA); completely cut off after full, no trickle floating charge , but monitor the voltage at any time, if the 18650 lithium battery voltage drops to a certain value and then start charging.
18650 lithium-ion battery packs are commonly used in a broad spectrum of applications, including:
Energy storage. Mainly used in base station power supply, clean energy storage, grid power storage, home solar storage system, etc.
Power class. Mainly refers to electric vehicles, electric bicycles, new energy vehicles, etc.
Digital consumer electronics. Mobile phones, tablets, laptops, electric toys, MP3/MP4, earphones, power banks, model airplanes, power banks, etc.
To understand the real demands of the lithium-ion battery pack design, you need to provide the lithium battery size, electrical performance requirements, output requirements, and functional information.
Evaluate a solution and quote the known parameters provided by the customer, also provide full datasheet for reference. We will consider the cell selection, circuit and structure design to final assembly.
After the customer’s approval, we will start to make samples for the lithium-ion battery pack, and provide charging and discharging cycle curve and data.
Before delivering out, we definitely do battery pack aging test. Assist and track customer test results, as well as customer’s overall equipment operation effect.
We will discuss with customer certificate works based on the final country and applicate requests. It may be MSDS, UN38.3, IEC62133, KC, PSE, etc.
Develop process documents and BOM sheet, purchase materials, arrange staff production, quality personnel monitoring, and random inspection, and package and shipment.
It includes the whole 14 steps to whole lithium battery packs. It includes cell inspection & test, solder PCB/nickel strip/cell, highland barley paper insulation, aging test, packing and delivery.
The battery should be stored at room temperature, and charged to 40%~60% electric quantity.
Reliable & durable lithium-ion battery manufacturer in China with over 10 years experience.
