A battery assembly for an electronic cigarette, an electronic cigarette and a control method therefor. In the battery assembly (10) for an electronic cigarette, a microcontroller (102) is simultaneously connected to a battery (101) and an atomisation assembly (20), enabling the battery (101) and the atomisation assembly (20) to form a current loop. The microcontroller (102) is also respectively connected to a high voltage end and a low voltage end of a heating wire of the atomisation assembly (20) via different pins. The connection relationship enables the microcontroller (102) to obtain a relevant parameter from the heating wire via the various pins, and thereby determine a resistance value of the heating wire. When it is determined that the resistance value of the heating wire of the atomisation assembly (20) exceeds a resistance preset range, the microcontroller (102) controls a circuit between the battery (101) and the heating wire of the atomisation assembly (20) to be disconnected. When the battery assembly (10) for an electronic cigarette does not match the power of the atomisation assembly (20), the electronic cigarette is thus stopped from working, thereby preventing there being an insufficient amount of vapour during use, and preventing the battery from heating and leaking fluid. |
