The invention provides a current adjusting method and device and electronic equipment, and relates to the technical field of power control, and the method comprises the steps: determining the upper limit of the load current of each phase according to the load current and the up-regulation load current of each phase in a three-phase branch, and the up-regulation current of each charging pile connected with the three-phase branch; determining a three-phase unbalance degree according to the load current upper limit of each phase; under the condition that the three-phase unbalance degree is greater than an unbalance degree threshold value, determining a load current balance interval corresponding to three-phase balance according to the load current upper limit of each phase; determining expected load current of each phase according to the load current upper limit, the load current lower limit and the load current balance interval of each phase; the working current of the charging pile connected with each phase is adjusted according to the expected load current of each phase, and the lower limit of the load current of each phase is determined according to the load current of the phase and the adjustable current of each charging pile connected with the phase. According to the technical scheme, the three-phase unbalance degree can be reduced, and the power supply efficiency is improved.
