Patent number: 10720791Abstract: Embodiments of the present disclosure provide a charging method, a charging device and a terminal. According to the embodiments of the present disclosure, a current battery voltage of a battery of a terminal is obtained. A current remaining electric quantity of the battery is obtained according to the current battery voltage. A charging duration of the battery at each charging stage is obtained according to the remaining electric quantity. The battery is charged according to the charging duration of the battery at each charging stage. This solution can increase a charging speed of the terminal.Type: GrantFiled: November 2, 2017Date of Patent: July 21, 2020Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventors: Qiang Zhang, Fanhong Kong, Fuchun Liao

Patent number: 10666063Abstract: Embodiments of the present disclosure provide a charging method, a charging device and a terminal. The charging method includes: when detecting that a battery is charged with a trickle current, acquiring a voltage of the battery; determining a preset voltage range to which the voltage belongs; acquiring a charging current corresponding to the preset voltage range; and charging the battery according to the charging current. During a process that the battery is charged with the trickle current, the battery may be charged with a different charging current when the voltage of the battery belongs to a different voltage range, thereby improving the flexibility of a trickle current charge phase.Type: GrantFiled: June 10, 2019Date of Patent: May 26, 2020Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventors: Qiang Zhang, Fanhong Kong, Fuchun Liao

Patent number: 10498156Abstract: A charging control method, a charging control device and a terminal are provided. According to the charging control method, it is determined whether the present charging stage is the constant voltage charging stage. The predetermined charging cut-off voltage is increased to the first charging cut-off voltage if the present charging stage is the constant voltage charging stage. The charging current and the battery voltage are periodically detected at a predetermined time interval. The first charging cut-off voltage is decreased by the predetermined voltage adjustment magnitude when the charging current is greater than or equal to the predetermined threshold and the battery voltage is greater than or equal to the safety voltage. The charging is completed when the charging current is less than the predetermined threshold.Type: GrantFiled: October 4, 2017Date of Patent: December 3, 2019Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventors: Qiang Zhang, Fanhong Kong, Fuchun Liao

Patent number: 10439406Abstract: The present disclosure provides a method and an apparatus for charging and a terminal. In the present disclosure, remaining electric quantities in the two batteries may be acquired. A trickle-current charging and a constant-current charging may be performed on a first battery of the two batteries in sequence when the remaining electric quantities in the two batteries are less than a preset value. It may be stopped to charge the first battery and the trickle-current charging and the constant-current charging may be performed on a second battery of the two batteries in sequence when a charging state of the first battery is changed from the constant-current charging to a constant-voltage charging. The constant-voltage charging may be performed on the two batteries simultaneously when the constant-current charging for the second battery finishes.Type: GrantFiled: November 2, 2017Date of Patent: October 8, 2019Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventors: Qiang Zhang, Fanhong Kong, Fuchun Liao
