On March 20, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Shenzhen Yingjixin Technology Co., Ltd. has obtained a patent authorization entitled "a charging circuit and method for automatically adjusting the voltage input according to the battery voltage", with the authorization announcement number CN110739752B and the application date of October 2019.
The patent abstract shows that the present invention discloses a charging circuit and method that automatically adjusts voltage input based on battery voltage. The circuit includes an AC input power supply, an adapter, a voltage stabilizing control module, and a battery module. The adapter is a fast charging adapter, and the voltage and current detection end of the voltage stabilizing control module detects the battery voltage and charging current of the battery module. The voltage stabilizing control module generates a feedback signal based on the detected battery voltage signal and charging current signal, and outputs it to the fast charging adapter. The fast charging adapter outputs an adjusted voltage signal to the stable voltage control module based on the feedback signal to control the output voltage of the stable voltage control module. This method is applied to the charging circuit mentioned above. The present invention can automatically adjust the output voltage of the fast charging adapter based on the battery voltage to improve charging power and efficiency, reduce heating, and shorten charging time.
