Abstract
The invention discloses a series mode calibration method for parallel formation and capacity grading equipment, a power supply calibration system and electronic equipment, which are applied to the power supply calibration system, and mainly comprises the following steps: sending a setting instruction and a test instruction through an upper computer, and respectively selecting two charging channels from a first series unit and a second series unit which are connected in parallel; according to the method, two channels in two series units are used for charging to obtain a current true value, an upper computer calculates a calibration coefficient according to the current true value and a sampling current value, and a power supply connected with each channel carries out precision calibration on charging and discharging current according to the calibration coefficient. The multiple channels are connected in series and then are calibrated, so that the cost is reduced, the calibration efficiency is improved, and the consistency of the current precision of different power supplies after calibration is also improved.
