Claim 0:
1. A charging method, applied to a charging box, comprising the following steps:
when the charging box detected that short-range wireless earphones are placed in the charging box, acquiring current capacity information of the short-range wireless earphones;
determining a number of Short-range wireless earphones according to the current capacity information;
if the number of Short-range wireless earphones is two, calculating a capacity difference and a total charging capacity required according to a first current capacity and a second current capacity in the current capacity information; and
acquiring a chargeable capacity of the charging box, comparing the chargeable capacity with the total charging capacity required and the capacity difference, and charging the Short-range wireless earphones according to comparison results,
the step of charging the Short-range wireless earphones according to comparison results comprises:
if the chargeable capacity is greater than or equal to the total charging capacity required, charging the two Short-range wireless earphones respectively until charging of the two Short-range wireless earphones is completed,
if the chargeable capacity is greater than or equal to the capacity difference and less than the total charging capacity required, calculating a target charging capacity of the Short-range wireless earphones according to the chargeable capacity, the preset charging efficiency, the first current capacity and the second current capacity;
sending the target charging capacity to the two Short-range wireless earphones respectively, and charging the two Short-range wireless earphones respectively; wherein the target charging capacity sent to the two Short-range wireless earphones is the same, and
when receiving charging stop information sent by either of the two Short-range wireless earphones based on the target charging capacity, stop charging a corresponding Short-range wireless earphone according to the charging stop information,
if the rechargeable capacity is less than the capacity difference, taking a Short-range wireless earphone with a lower capacity in the two Short-range wireless earphones as the target Short-range wireless earphone; and
charging the target Short-range wireless earphone, and disconnecting a non-target Short-range wireless earphone from a charging circuit.
