Abstract

The invention discloses a charger calibration method, a calibration system and a charger. A main control device sends a reference electrical parameter to a programmable power supply, so that the programmable power supply outputs preset control electric energy, and then an electrical detection module detects and obtains a charging electrical parameter; a pre-stored electrical parameter corresponding to the reference electrical parameter is determined by a processing module in the charger to be tested, and the pre-stored electrical parameter is compared with the charging electrical parameter to obtain a comparison result; and finally, corresponding calibration parameter adjustment is carried out based on the comparison result. According to the technical scheme of the invention, calibration parameters in the charger to be tested can be automatically corrected and adjusted, and the adjusted calibration parameters can be matched with each electrical detection module individual. The method has the technical effects of improving the accuracy of the calibration parameters of the electrical detection module of the charger and improving the setting efficiency and applicability of the calibration parameters.

Description

technical field [0001] The invention relates to the technical field of charging equipment production, in particular to a charger calibration method, a calibration system and a charger. Background technique [0002] At present, charger products usually need to set the calibration data of their electrical detection modules before leaving the factory, which is determined by the following two aspects: [0003] First, charger products usually need to detect the input grid voltage during use and set up a circuit protection function. When the grid voltage is abnormal, the power supply circuit of the charger needs to be closed to avoid circuit damage. If there is a detection deviation in the electrical detection module such as voltage or current, and there is a large gap between the data obtained by the detection and the actual data, the charger product is likely to have a circuit protection function failure or an abnormal circuit protection. [0004] Second, the output of the char...
