What are the functions of lithium battery sorter?

Lithium battery separator is very close relations with lithium battery, its play a very important role in the first place in our daily life, most of the time need to use lithium battery products, it is good, for example, we often use the lithium battery electric bicycle to work, is a good example, including lithium battery automatic bicycle transport 70% daily life, The power and energy inside a lithium battery bike is a whole battery pack. Second is how to determine the power lithium battery pack is complete, uniform and safe, this is the lithium battery separator play the role of the separator is through the internal resistance, voltage, internal pressure, thus concludes that each cell of the data, so as to achieve every single cell, as well as the data that produce lithium battery pack, security and durable.

Lithium battery internal resistance testing: refers to the battery at work, current flows through the battery internal resistance, generally divided into ac resistance and dc resistance, because the rechargeable battery internal resistance is very small, when measuring the dc resistance due to the capacity of electrode polarization, polarization resistance, its real value, so it can not be measured and the ac impedance measurement can be exempted from the influence of polarization resistance, it is concluded that the real value.

Test lithium battery voltage: refers to the potential difference between the positive and negative terminals of the battery when the current flows through the circuit after the lithium battery is connected to the load, also known as the discharge voltage. The working voltage of lithium battery is lower than open circuit voltage due to ohmic resistance and polarization overpotential. Test the internal pressure of lithium battery: refers to the internal pressure of lithium battery formed by the gas generated in the charging and discharging process. It is mainly affected by the manufacturing process of battery materials, structure and other operating process factors. Generally, the internal pressure of the battery is maintained at a normal level, and may increase under the condition of overcharge or overdischarge.

In simple terms, the lithium battery separator is lithium battery assembly equipment inspection lithium battery one part of the link, the step is to ensure that each batteries every value, so to put behind these same numerical lithium-ion batteries, welded into a lithium battery pack, the installed protection board, is basically a finished product, can be installed directly to the electric bicycle use.
