In order to improve the electrochemical performance of the battery such as cycle life, stability, self-discharge, and safety, it is necessary to strictly control the consistency of the lithium battery or accurately evaluate the battery grade.
Therefore, there are very high requirements for the measurement accuracy of current and voltage of the formation and capacity separation equipment, which is limited to the acquisition accuracy of the sensor. Currently, the measurement accuracy of the current and voltage of the formation and capacity separation equipment on the market is generally about one thousandth.
For formation, the higher the control accuracy of current and voltage, the better the quality of lithium battery products, and the accuracy of current and voltage sensors above one ten thousandth is an ideal choice.
