Test lithium-ion battery equipment quality good approach 1, the fastest test method is to detect internal resistance and maximum discharge current, quality lithium-ion battery equipment, the internal resistance is very small, the maximum discharge current is large. With a 20A range of multimeters, the straight shorts of the two electrodes of the lithium-ion battery, the current should generally be around 10A, even higher, and can be kept for a period of time, relatively stable is a good battery. 2, look at the appearance; the extent of the appearance, such as the lithium-ion battery equipment, generally 2000mAh, large volume.

Finishing work is relatively full of packaging. 3, see hardness; you can use your hand to pinch or moderately pinch the middle part of the lithium ion battery equipment, the hardness is moderate, and there is no soft extrusion that the lithium battery belongs to a relatively high quality battery. 4, look weight; remove the outer packaging aware of the battery weight is more sinking, if the thickness belongs to the quality battery.

5. During the charging process of lithium-ion battery equipment, the battery is continuously discharged for about 10 minutes. If the battery is not hot, it is proved that the battery protection board system is perfect, and the quality of lithium-ion battery equipment with high quality protective plate is generally better than the general lithium-ion battery.

Okay. Lithium-ion battery performance detection equipment and method lithium-ion battery performance detection is subject to power, internal resistance, capacity, inner teeth, self-discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance, etc. , Overlapping, weldability, corrosion resistance, etc.

When selecting a battery detection system, consider the capacity range of the battery or battery pack and the voltage range of the battery pack. The battery detection system can be divided into micro-current web and large current scale equipment. (1) The current range of micro-current web detection equipment is a few millians to several measuring devices such as IMA, 2MA, SMA, LOMA, LOOMA, 500MA, LOOOOMA, 1800mA, 3000mA, 5000mA and other ranges; (2) The current range of large current range detecting equipment is several-to-a hundred, such as specifications such as 10A, 20A, 40A, 60A, 100A.

Compared with other rechargeable batteries, the lithium-ion battery has the advantage of high energy density, high voltage, long life, no memory effect. With the further improvement of lithium-ion battery processing technology and battery performance, the lithium-ion battery will occupy the energy storage battery. The mainstream market in the category of the dynamic lithium-ion battery; the foreign knowledge of the lithium-ion battery performance detection system has a lot of manufacturers, and the performance of lithium-ion battery performance in domestic representative manufacturers is well received, and it is far ahead in the battery exploration industry.
