Description

technical field [0001] The invention relates to a calibration device, in particular to an automatic calibration device and a calibration method for a portable charging and discharging device. Background technique [0002] At present, the demand for lithium battery cells and battery packs in the market is increasing, and the demand for battery charging and discharging equipment is also increasing. Due to the characteristics of electronic components, the circuit parameters of these charging and discharging equipment will change when they leave the factory or after long-term operation, and the accuracy will also deviate. At this time, it is necessary to calibrate the charging and discharging equipment. [0003] For charging and discharging equipment, the existing calibration method is mainly realized through manual calibration, specifically: with the help of high-precision voltage ammeter and DC source, several calibration points are selected according to the range of charging ...

AI Technical Summary

Problems solved by technology

However, the shortcomings of this manual calibration method are: 1. Multiple high-precision voltage and ammeters and DC sources need to be equipped, which is not only expensive, but also cumbersome and inconvenient to carry; Professionals who are familiar with charging and discharging equipment operate, and the calibration is relatively cumbersome and takes a long time; 3. When there are a large number of charging and discharging equipment that needs to be calibrated, there are problems such as heavy workload and high error rate.
