Combined with the above connection relationship, the working principle of the electronic cigarette USB charger provided in this embodiment is explained:

The microprocessor outputs a 5VDC current-limiting current A1. Here, the current-limiting current A1 is set to be much larger than the constant-current charging current A2 of conventional e-cigarette battery linear charging management, and then the e-cigarette battery is charged for a preset time. Here, it can be 1 Second. The microprocessor detects the current A3 through the output current detection module, and compares the current value. If A3≥(1+50%)A2, there is no charging management inside the battery pole; if A3﹤(1+50%)A2, the inside of the battery pole for linear charge management.

If the battery pole does not contain charging management, the voltage value detected by the microprocessor is the battery voltage. If the battery pole contains linear constant current charging management, the battery voltage is detected as follows:

Since the battery pole is charged with a linear constant current, the charging voltage should be appropriately reduced until the charging current is less than the preset constant current value of the battery pole charging. At this time, the output charging voltage is only about 0.2V greater than the battery voltage inside the battery pole. Using this principle, the microcontroller can get the voltage of the battery pole battery. The microcontroller adjusts the output voltage of the DC-DC booster module with adjustable output until the charging current is 5-10% smaller than the charging current at 5V output. At this time, the output voltage minus 0.2V is the voltage of the battery.

Afterwards, the microprocessor displays the detected voltage through LED lights, such as displaying the power of the battery pole with a long bright LED, and displaying charging with a blinking LED.

It can be seen that the electronic cigarette USB charger provided by the utility model has the power display function, and when the voltage of the electronic cigarette is lower than the set value, it will give the user a reminder, which effectively solves the problem that the user cannot find the electronic cigarette in time when using the existing technology.
