IT Home January 17 news, last November 30, Zhuhai Meizu Technology Co., Ltd. publicly released a "shunt battery charge and discharge control system and its control method, electronic equipment" patent, in the charging technology layout.
According to digital blogger @Li Ang Ang'aon, Meizu's fast charging of more than 50W is expected to arrive soon.
IT Home learned that the patent abstract of the enterprise check App shows that this 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.
Battery charge and discharge control module is a control buck circuit module, the first charge pump circuit module and the second charge pump circuit module working in the corresponding charge and discharge stage of the control module; the buck circuit module works in the trickle charging stage, the constant current charging stage, the constant voltage charging stage and the 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 voltage circuit module suitable for the system power supply module. Improved charging efficiency.
