Abstract

The invention discloses a charger's output current correction method, comprising: entering a current correction mode when a current correction command of a user is detected and sending a current pre-output command to the charger so that the charger outputs according to the preset current value recorded in the current pre-output command; detecting the output current of the charger periodically; calculating the difference between the detected output current and the preset current value; determining whether the difference falls within the range of a predetermined value; if not, sending the current correction information to the charger to enable the charger to correct the output current according to the current correction information; and if yes, sending the information indicating the success of current correction to the charger and stopping the sending of the current correction information to the charger so that the charger updates the current output parameters saved in a saving unit according to the most recently received current correction information. The charger's output current correction method of the present invention improves the production efficiency. The present invention also provides a charger's output current correction device, an output voltage correction method and a correction device for the output voltage.

Description

technical field [0001] The invention relates to the field of electric vehicle chargers, in particular to a charger current and voltage correction method and device. Background technique [0002] At present, electric vehicles mostly use charging piles to achieve charging. With the improvement of people's requirements for charging timeliness and flexibility, electric vehicle chargers have gradually developed. [0003] In actual production, in order to ensure that the output voltage and output current of the electric vehicle charger fall within the specified range and ensure the consistency of mass production, the electric vehicle charger needs to be calibrated before leaving the factory. [0004] The existing correction method is: setting an automatic correction circuit inside the electric vehicle charger, measuring the overall error of the charger by self-checking the parameters of the charging and discharging process of the electric vehicle charger, and performing automatic ...
