And S203, dynamically distributing charging power to the electronic equipment based on a preset period according to the preset charging parameters and the preset charging duration in each electronic equipment.
On the basis of the preset charging parameters in each electronic device, a distribution rule for dynamically distributing the charging power to each electronic device is formulated, and the distribution rule is related to the charging duration, so that when at least one electronic device is charged simultaneously, the distributed charging power is continuously adjusted according to the charging duration based on a preset period. The predetermined period may be any time period set by a technician of interest, such as 1 minute, 30 seconds, or 2 minutes. The method comprehensively considers the charging time and the charging parameters of the electronic equipment, adjusts the charging power distributed to each electronic equipment based on the preset period,
for example, the allocation rule is to give priority to full power charging of the electronic device with the minimum fixed power, and as the charging time period increases, the charging power distributed to the electronic device with the minimum fixed power is reduced, and the surplus power is further allocated to the electronic device with the second minimum fixed power. It is to be understood that the above distribution rule is only an example, and a person skilled in the relevant art can set any distribution rule for dynamically distributing charging power when charging at least one electronic device as required.
The electronic equipment is tested by providing the test power with at least two different power values for the electronic equipment, so that the preset charging parameter in each electronic equipment is obtained, the charging parameter is provided as a basis when a power distribution strategy is formulated for at least one electronic equipment, on the premise that the requirement of each electronic equipment for the charging power is met, the total charging power provided by the charging equipment is dynamically distributed for at least one electronic equipment according to the power distribution strategy, the difference caused by different charging modes among various electronic equipment is considered, the compatibility of various electronic equipment is improved, the power utilization rate of the charging equipment is effectively improved, the power waste is avoided, and the charging experience of at least one electronic equipment which is charged through the charging equipment at the same time is improved.
