On January 17, it was reported that on November 30 last year, Zhuhai Meizu Technology Co., Ltd. disclosed a patent for a "shunt battery charge and discharge control system and its control method and electronic equipment" to layout in charging technology.
According to the news released by digital bloggers, Meizu's fast charging of more than 50W is expected to arrive soon.
According to the enterprise check App patent abstract, the present disclosure involves a shunt battery charge and discharge control system and its control method, electronic equipment, including charge and discharge circuit and three-cell battery; battery connector includes at least the first battery connector and a second battery connector; the charge and discharge circuit includes a step-down circuit module, a first charge pump circuit module, a second charge pump circuit module, a battery charge and discharge control module and a system power supply module.
The battery charge and discharge control module is a control buck circuit module, a first charge pump circuit module and a second charge pump circuit module that works in the corresponding charge and discharge stage; the buck circuit module works in the trickle charging stage, a constant current charging stage, a constant voltage charging stage and a charging off stage;
The first charge pump circuit module works in the constant current charging stage; the second charge pump circuit module also works in the discharge stage, in order to convert the discharge voltage of the three-cell battery into a circuit module suitable for the voltage of the system power supply module, improving the charging efficiency.
