Patent number: 11023224Abstract: A firmware update method for a smart charging device is disclosed. First, firmware of a first board is updated, and the first board then sets work flags to second, third board and fourth boards. The first board queries a firmware version of the second board, and then presets the work flag of a firmware version as false. When the firmware version of the second board is older, the first board sets the work flag as true, and updates the firmware of the second board, and sets the work flag as false. The first board again queries whether the work flag is set as true, when the firmware versions of the second and first boards are the same, the work flag is set as false. According to the above procedures, the firmware of the third and fourth boards is updated, so as to completely update firmware of all boards.Type: GrantFiled: October 1, 2019Date of Patent: June 1, 2021Assignee: Chen-Source Inc.Inventor: Bai-Lian Zhou
