Meizu 50W+ fast charging is coming, and a patent for dual-cell solution has been applied for

On November 30 last year, Zhuhai Meizu Technology Co., Ltd. disclosed a patent for "shunt-type battery charging and discharging control system, control method and electronic device", making a layout in charging technology.

　　According to digital blogger @李昂昂昂啊, Meizu's 50W and above fast charging is expected to arrive soon.

　　IT Home learned that the patent abstract of Qichacha App shows that the present disclosure relates to a shunt-type battery charging and discharging control system and its control method, an electronic device, including a charging and discharging circuit and a three-cell battery; the battery connector includes at least a first battery connector and a second battery connector; the charging and discharging circuit includes a step-down circuit module, a first charge pump circuit module, a second charge pump circuit module, a battery charging and discharging control module and a system power supply module.

　　The battery charge and discharge control module is a control module that controls the step-down circuit module, the first charge pump circuit module and the second charge pump circuit module to operate in the corresponding charge and discharge stages; the step-down circuit module operates in the trickle charging stage, the constant current charging stage, the constant voltage charging stage and the charging cut-off stage; the first charge pump circuit module operates in the constant current charging stage; the second charge pump circuit module also operates in the discharge stage, and is a circuit module that converts the discharge voltage of the three-cell battery into a voltage suitable for the system power supply module, thereby improving the charging efficiency.
