Abstract

The invention discloses a charging method, a charging controller and a charging system . The charging method includes the following steps: when a power receiving device is charged by a charging device through a transmission cable with a charging voltage, a current passing through a battery charging circuit is detected by a sensor. The charging information associated with the current is sent to a transmission module of the power receiving device through a monitoring program, and then the charging information is sent back to the charging device by the transmission module through the communication channel of the transmission cable. The transmission module of the charging device determines whether the charging information is satisfied with the stop condition. If so, the charging voltage is maintained to charge the power receiving device continuously. If not, the output charging voltage is gradually adjusted until the stop condition is satisfied.

Description

technical field [0001] The present invention relates to a charging method, a charging controller and a charging system, in particular to a kind of electronic device and a transmission wire suitable for various charging. By adjusting the output voltage, the electronic device can receive the maximum voltage during charging. Charging current, thereby reducing charging method, charging controller and charging system of charging time. Background technique [0002] The use of mobile devices such as smartphones and tablet computers has become quite popular. These wireless mobile devices must rely on the batteries in the devices to provide power for device operations when they are not connected to the power supply line. The performance of the batteries directly affects the operation of the mobile devices. The time and the way of charging the battery also directly affect the convenience of use. As the functions of mobile devices continue to improve, the demand for power consumption ...
