First, the controller <NUM> determines the status of the battery <NUM>.

In this embodiment, when the controller <NUM> receives a start command, it means that the controller <NUM> controls the battery <NUM> to enter the discharging state, and when the controller <NUM> receives an off command, it means that the controller <NUM> controls the battery <NUM> to end the discharging state; when the controller <NUM> receives a charge command, it means that the controller <NUM> controls the battery <NUM> to enter the charging state, and when the controller <NUM> When the controller <NUM> receives the end command, it means that the controller <NUM> controls the battery <NUM> to end the charging state.

Based on this, the controller <NUM> determines the status of the battery <NUM> based on the instructions received.

Specifically, in the case of the end of the discharge state as well as the end of the charge state, when the controller <NUM> receives a start command (or a charge command), the controller <NUM> determines that the battery <NUM> enters the working state from the idle state, and if the controller <NUM> receives a shutdown command (or an end command) at the next moment, the controller <NUM> determines that the battery <NUM> enters the idle state from the working state.

In the case of ending the discharge state as well as ending the charge state, when the controller <NUM> receives a start command (or a charge command), the controller <NUM> determines that the battery <NUM> enters the working state from the idle state, and if the controller <NUM> receives a charge command (or a start command) at the next moment, the controller <NUM> determines that the battery <NUM> enters the idle state from the working state only after receiving the shutdown command and the end command.

Further, after the controller <NUM> determines the status of the battery <NUM>, the controller <NUM> obtains battery information from the detector <NUM> based on the determined status. wherein the step of the controller <NUM> obtaining battery information from the detector <NUM> includes: after the detector <NUM> collects battery information of the battery <NUM> in real time, the controller <NUM> obtains the required battery information from the battery information collected by the detector <NUM> in real time; or, after the controller <NUM> controls the detector <NUM> to collect the required battery information from the battery <NUM>, the controller <NUM> obtains the battery information from the detector <NUM>.

When the controller <NUM> determines that the state of the battery <NUM> enters the idle state from the working state, the controller <NUM> obtains the first battery voltage from the detector <NUM> when the battery <NUM> enters the idle state, and obtains the second battery voltage from the detector <NUM> when the battery <NUM> enters the working state from the idle state when the state of the battery <NUM> enters the working state from the idle state again.

In some alternative embodiments, when the controller <NUM> determines that the state of the battery <NUM> is the working state, the controller <NUM> is also capable of acquiring the battery information from the detector <NUM> at predetermined intervals and record the acquisition time.

Further, after the controller <NUM> obtains the battery information, the controller <NUM> determines whether the battery <NUM> is abnormal based on the battery information and controls the electronic cigarette to send an alarm signal and/or control the battery <NUM> to stop working when the battery <NUM> is abnormal.

Specifically, after the controller <NUM> obtains the first battery voltage and the second battery voltage, the controller <NUM> determines the actual voltage drop based on the first battery voltage and the second battery voltage; then the controller <NUM> determines whether the battery <NUM> is abnormal by judging whether the actual voltage drop is greater than the preset standard voltage drop, and if the actual voltage drop is greater than the preset standard voltage drop, the controller <NUM> determines that the battery <NUM> is abnormal.

If at least one of the difference between the actual battery charging and discharging capacity and the standard battery charging and the discharging capacity, the battery temperature, and the battery operating current is not within the preset standard range, then the controller <NUM> determines that the battery <NUM> is abnormal. wherein the step of the controller <NUM> calculating the actual battery charging and discharging capacity based on the battery voltage, the battery operating current and the acquisition time specifically comprising: the controller <NUM> extracts the third battery voltage and the first battery operating current corresponding to the current acquisition time and extracts the fourth battery voltage and the second battery operating current corresponding to the previous acquisition time; after the controller <NUM> determines a time interval between the current acquisition time and the previous acquisition time, the controller <NUM> calculates the actual battery charging and discharging capacity based on the time interval, the third battery voltage, the fourth battery voltage, the first battery operating current and the second battery operating current.

Of course, in some alternative embodiments, the predetermined battery model may also be a curve of the variation of battery voltage with the percentage of battery charging and discharging capacity.

The preset difference range, the preset standard temperature range, and the preset standard operating current range are related to the characteristics of the electronic cigarette and the battery <NUM>.
