Description
Technical Field
[0001] The utility model relates to the technical field of battery capacity cabinet test fixtures, in particular to a battery capacity cabinet test fixture. Background Art
[0002] Battery capacity sorting equipment calibration is the process of precisely adjusting and verifying the equipment used for battery capacity sorting to ensure the accuracy and reliability of its measurement and control. The following are some key aspects of battery capacity sorting equipment calibration: Current calibration: Use a high-precision standard current source to calibrate the current measurement module of the capacity sorting equipment. Voltage calibration: Use a standard voltage source to calibrate the voltage measurement portion of the equipment. This involves measuring and comparing different voltage levels to adjust the equipment's voltage measurement accuracy. Capacity calibration: Verify the accuracy of the capacity calculated by the capacity sorting equipment by testing standard batteries of known capacity. Temperature calibration: For capacity sorting equipment with temperature measurement capabilities, use a standard thermometer to calibrate its temperature measurement module. Time calibration: Ensure the accurate measurement of time-related parameters in the capacity sorting equipment, such as charge time and discharge time. A high-precision clock can be used as a standard to calibrate the equipment's time measurement. Control accuracy calibration: Verify the accuracy of the capacity sorting equipment's control over the charging and discharging processes, such as the accuracy of the cutoff voltage and current control.
[0003] After long-term use, battery capacity grading equipment is often affected by factors such as the environment and its own aging, resulting in accuracy deviations. The current solution is to use a multimeter to test and calibrate each point, which is an extremely cumbersome process. The existing calibration process requires the use of a multimeter to measure and calibrate each point individually, which is time-consuming and affects production operations. Therefore, a simple and convenient tooling is needed to improve efficiency. Utility Model Content
