Problems solved by technology
[0004] However, when the above charging method is adopted, due to the shared power transmission part, the charging process and the communication process are correspondingly suspended and switched according to the program of the main charging device. When the value is too low, the communication is not timely enough, and the charging parameters cannot be adjusted in time and effectively, resulting in abnormal charging.
[0005] Therefore, the traditional charging method has the problem of low charging efficiency from the powered device

The present invention proposes a charging method for a master-slave charging device and a master-slave charging device. The master-slave charging device includes a master charging device and at least one slave power receiving device. The slave power receiving device can configure the charging interruption condition according to the actual situation. When the charging interruption condition occurs, stop charging to allow the main charging device to establish communication with it. After the communication is established, the receiving device can feed back its own charging parameters, so that the main charging device can perform charging control in time according to the charging parameters fed back from the receiving device. The conversion from passive power receiving to active feedback power receiving from the power receiving device is beneficial to improve the charging efficiency of the power receiving device.
Description
technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a charging method for a master-slave charging device and the master-slave charging device. Background technique [0002] The traditional master-slave charging device charges the slave receiving device through the master charging device. In order to improve charging efficiency and safety, the master charging device communicates with the slave receiving device at a set time period or according to a preset program. Adjust the charging parameters according to the charging state of the electric equipment, so as to output the charging power required by the electric equipment. [0003] When charging, in order to reduce the signal line, the master-slave charging equipment usually shares the power transmission parts between the master-slave charging devices. The power transmission parts can be power lines, metal contacts, etc., that is, when charging, the charging power is ou...
