Automatic voltage internal resistance test equipment (DY5110) is a test battery open circuit voltage, internal resistance, temperature, bar code scanning, pole ear shaping function and battery automatic output of the fully automated test equipment, through the device's human-machine interface set parameters, the measured cell's internal resistance, voltage, temperature actual value and parameters worth comparing to determine whether qualified. At present, the latest equipment uses four-axis robot +CCD positioning technology + servo + battery tester and other ways to achieve a short change time when the equipment switches varieties, easy maintenance, simple operation, and this type of equipment is mainly sold to the major 3C lithium battery industry in China, has been recognized by most customers.
