Charger and charging method thereof

Abstract

A charger, the charger includes a charging port, the charging port is used to receive electrical signal input from an adapter, the charger further includes a detection unit electrically connected to the charging port, and a detection unit electrically connected to the detection unit. A control unit, the detection unit detects the input voltage and input current of the charger; the control unit determines whether the input voltage of the charger is within a preset voltage range, and when it is determined that the input voltage of the charger is within When the voltage is within the preset voltage range, the input current of the charger is controlled to gradually increase in a preset manner until the charger inputs the maximum power to enable the charger to perform charging. The invention also provides a charging method of the charger. By using the present invention, the input current of the charger can be gradually increased until the charger is input with the maximum power, and finally the maximum power output of the adapter can be achieved on the premise of ensuring the safety of the adapter operation.

Description

technical field [0001] The invention relates to charging technology, in particular to a charger and a charging method of the charger. Background technique [0002] With the continuous improvement of living standards, more and more electronic devices, such as mobile phones and IPADs, are emerging in the market. In order to be more portable, wireless chargers, charging treasures, back clip chargers and other chargers have become popular in the market to charge electronic devices such as mobile phones. Usually, when a user uses a wireless charger to charge an electric device, such as a mobile phone, the process is roughly as follows: first plug the adapter into an external power source, then connect the wireless charger, and then place the mobile phone on the wireless charger for charging . During the charging process, the mobile phone sends a demand command to the wireless charger according to its own power demand, and the wireless charger will work according to the power de...

Problems solved by technology

However, when the power required by the mobile phone itself is large, the wireless charger will work according to the high power required. Correspondingly, the wireless charger will require the adapter to be directly pulled up to a high-power output. Therefore, the high-power output may cause the adapter to Damaged or entering the self-preservation state does not work
