1. Test the voltage of the lithium battery:

It refers to the potential difference between the positive and negative poles of the battery when the current flows in the circuit after the lithium battery is connected to the load, also known as the discharge voltage. After the lithium battery is connected to the load, the operating voltage of the lithium battery is lower than the open circuit voltage due to the existence of ohmic resistance and polarization overpotential.

2. Test the internal pressure of the lithium battery:

Refers to the pressure formed by the internal pressure of the lithium battery due to the gas generated during the charging and discharging process. Mainly affected by the battery material manufacturing process, structure and other use process factors. Generally, the internal pressure of the battery is maintained at a normal level, in the case of overcharge or overdischarge The internal pressure of the battery may increase.

Lithium battery sorting machines are closely related to lithium batteries, and they play a very important role. First of all, in our daily life, many times we need to use lithium battery products. It is like an analogy, the lithium battery electric that we often use at work Bicycles are a good example. Among them, lithium battery automatic bicycles occupy 70% of daily transportation. The lithium battery bicycles provide power and energy in a whole battery pack. The second is how to determine that the entire lithium battery pack is of complete power, uniformity and safety. This is the role played by the lithium battery sorting machine. The sorting machine uses internal resistance, voltage, and internal pressure to obtain each battery cell. In order to achieve the same data of each battery cell, the lithium battery pack produced in this way is safe and durable.

Simply put, the lithium battery sorting machine is one of the parts of the lithium battery assembly equipment testing lithium batteries. The steps are to ensure that each cell has the same value. In this case, the lithium batteries of the same value are welded later. Into a lithium battery pack, after installing the protective board, it is basically a finished product, which can be directly installed on an electric bicycle for use.
