Problems solved by technology
Due to the aging of electronic components and the influence of temperature, the chemical composition test power supply is easy to cause the test accuracy to drop. When charging and discharging the power battery or super capacitor, the test accuracy of the power battery or super capacitor will drop. Therefore, in the chemical composition test When the accuracy of the power supply drops, the test channel data should be collected in real time and recalibrated
[0003] However, the calibration of the existing chemical composition and capacity test power supply is mostly completed before leaving the factory, and the calibration work after leaving the factory is cumbersome and inefficient
For the current composition and capacity test power supply, professionals are required to calibrate and inspect it. The degree of automation is low, and it cannot be calibrated in time to ensure its normal use when the accuracy of the composition and capacity test power supply drops.

The invention discloses an automatic calibration circuit and system for a formation and grading test power supply, and the circuit comprises an automatic sampling circuit, a standard voltage circuit and a shunt. The automatic sampling circuit is connected with the standard voltage circuit, and the standard voltage circuit is connected with a sampling circuit of the test power supply. The shunt isconnected with the automatic sampling circuit and the sampling circuit of the test power supply. When one test channel is in calibration, the remaining test channels are closed in a calibration process. The circuit can achieve the automatic collection and calibration of all channel parameters of the test power supply, obtains a new calibration coefficient, achieves the programming of the new calibration coefficient into the corresponding channels, and improves the precision of the test power supply.
Description
technical field [0001] The invention relates to the field of power batteries or supercapacitors, in particular to an automatic calibration circuit and system for chemical composition capacity test power supply. Background technique [0002] With the rapid development of my country's economy, society and new energy industry, power batteries or supercapacitors are widely used in electric buses, electric vehicles, large-scale energy storage systems, etc. Power batteries or supercapacitors often need to be tested during the production process, and the equipment used for testing usually uses a chemical composition and capacity test power supply. Due to the aging of electronic components and the influence of temperature, the chemical composition test power supply is easy to cause the test accuracy to drop. When charging and discharging the power battery or super capacitor, the test accuracy of the power battery or super capacitor will drop. Therefore, in the chemical composition t...
