The working principle of the electronic cigarette USB charger provided in this embodiment is described in conjunction with the above connection relationship:

The processor outputs a 5 VDC current limiting current A1. Here, the current limiting current A1 is set to be much larger than the constant current charging current A2 of the conventional electronic cigarette battery linear charging management, and then the electronic cigarette battery is charged for a preset time, which 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 charge management inside the battery rod; if A3 < (1+50%) A2, the battery ^^ Internal for linear charge management.

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

Since the battery is linear constant current charging, the charging voltage is appropriately reduced until the charging current is less than the preset constant current value of the battery rod charging, and the output charging voltage at this time is only about 0.2 V larger than the battery voltage inside the battery rod. Using this principle, the microprocessor can get the voltage of the battery rod battery. Micro processing The output voltage of the DC-DC boost module with adjustable output is adjusted until the charging current is 5-10% smaller than the charging current at the output of 5V. At this time, the output voltage is reduced by 0.2V, which is the voltage of the battery.

After that, the microprocessor displays it according to the detected voltage through the LED light, such as the battery with long light LED; ^ power, flashing LED shows charging.

It can be seen that the electronic cigarette USB charger provided by the invention has a power display function, and when the electronic cigarette voltage is lower than the set value, the user is prompted to effectively solve the problem that the user fails to find the electronic cigarette in time when using the electronic technology in the prior art.
