1. A battery health monitoring method, applicable to an electronic cigarette, wherein said electronic cigarette comprises a battery, a detector, and a controller, said detector connected to said controller, and both said detector and said controller connected to said battery;
wherein said battery health monitoring method comprises the steps of:
said controller acquiring battery information from said detector based on state of said battery; wherein said state of said battery comprises: a working state and an idle state;
said controller determining whether said battery is abnormal based on said battery information; and
if said battery is abnormal, said controller controlling said electronic cigarette to issue an alarm signal and/or controlling said battery to stop working
wherein when said state of the battery enters the idle state from the working state, said controller acquires from said detector a first battery voltage when the battery enters the idle state and acquires a second battery voltage when the battery enters the working state from the idle state;
and wherein, the step of said controller determines whether said battery is abnormal based on said battery information specifically comprises:
said controller determining an actual voltage drop based on said first battery voltage and said second battery voltage;
said controller determining whether said actual voltage drop is greater than a preset value of voltage drop, and said controller determining that said battery is abnormal if said actual voltage drop is greater than said preset value.
