1. A method for determining a charging circuit, applied to a first electronic device, wherein the first electronic device is stored with a preset equivalent circuit model, the method comprising:
acquiring the preset equivalent circuit model comprising a preset number of charging paths, wherein one or more of the preset number of charging paths comprise a controllable device;
controlling an operating state of a first controllable device to obtain a first initial equivalent circuit, wherein the first initial equivalent circuit comprises a first charging path different than a second charging path of a second initial equivalent circuit comprising a second controllable device, and wherein the first controllable device and second controllable device include a first operating state in which the controllable device is a non-zero resistor, or a second operating state in which resistance of the controllable device is infinite;
acquiring a charging current in the charging path of the first initial equivalent circuit in a charging state;
acquiring a charging current in the charging path of the second initial equivalent circuit in a charging state;
for the first initial equivalent circuit, acquiring a heat loss value of the initial equivalent circuit based on the charging current in the charging path of the first initial equivalent circuit and a resistance value of the equivalent device in the equivalent circuit model;
for the second initial equivalent circuit, acquiring a heat loss value of the initial equivalent circuit based on the charging current in the charging path of the second initial equivalent circuit and a resistance value of the equivalent device in the equivalent circuit model;
determining one of the initial equivalent circuits having a minimum heat loss value under a same condition as a target charging circuit; and
deploying, in a second electronic device, an actual charging circuit corresponding to the target charging circuit and using the actual charging circuit to charge for the second electronic device under the same condition.
