  • the SOC of the aerosol provision device has a corresponding charging voltage value.
  • the production line operator generally judges whether the charging amount reaches the target value according to the charging voltage value.
  • the overall resistance value of the aerosol provision system is relatively fixed. Based on this, in the present invention, the maximum charging amount or the maximum charging voltage value of the device can be adjusted by identifying the change in the resistance value of the aerosol provision device, so as to achieve the effect of stopping when the target charging amount is reached.
  • some external devices with specific resistance values can be selected. According to specific charging requirements, an external device with a corresponding resistance value is selected and connected to the device for charging the device.
  • an external device with a resistance value larger than 2 ohms, such as 5 ohms can be selected and connected to the device. After the device detects that the connected resistance value is not the conventional resistance value, it adjusts the maximum charging amount of its battery. In practice, the target charging amount can be corresponded by adjusting the maximum charging voltage. Further, the external device can be a cartridge.
  • Step S102 Based on the correspondence relationship between the resistance value and the charging amount, determining the target charging amount corresponding to the resistance value.
  • the method for determining the target charging amount corresponding to the resistance value is as follows: If the resistance value of the external device is greater than or equal to the first threshold, the changed target charging amount is the first target charging amount; if the resistance value is less than the first threshold, the target charging amount of the device is determined to be the second target charging amount. Based on the set threshold, the corresponding target charging amount is adjusted. Different threshold ranges have corresponding target charging amounts. The target charging amount is determined according to whether the resistance value is within the threshold range, so as to charge according to the production requirements.
  • the first threshold can be a value greater than the conventional resistance value of the device; during the production process, the maximum value of the battery charging voltage is automatically adjusted to the target charging voltage value to replace the fully charged state.
  • the battery can be fully charged normally, and there is no complicated operation during the manufacturing process.
  • the resistance value is greater than or equal to the first threshold
  • the set value of the second threshold needs to be greater than the first threshold.
  • the target charging amount is adjusted to the first target charging amount; otherwise, the current target charging amount is continuously maintained.
  • the resistance value of the connected external device also needs to be within a certain range. If it is too large, it may cause that no electricity can be charged. Therefore, it needs to be kept within a reasonable range.
  • the specific size of the threshold can be reasonably selected according to the acceptable range of the device, which is not limited in the present invention.
  • the cartridge is used as the external device because the cartridge can be directly connected and installed to the aerosol provision device in a detachable manner.
  • the device 100 does not need an additional interface to connect to the device. It can directly connect cartridges 200 with different resistance values through the power supply pins to achieve the adjustment of different target charging amounts.
  • the resistance value of an ordinary cartridge 200 is 1 ohm. Therefore, the resistance value of the cartridge 200 in production can be designed to be 5 ohms.
  • the device 100 can identify through the controller 101 that the inserted cartridge 200 has a resistance value of 5 ohms, and adjust and reduce the target charging amount, so that the charging device or the external power supply charges the battery 102 according to the reduced target charging amount.
  • the device 100 adjusts and restores the original maximum charging amount, and the battery 102 can still be fully charged, ensuring the normal use of the user. There is no need for additional steps to restore the 100% SOC charging capacity, which saves time and effort, does not increase the production cost, and ensures the stable charging demand of the product.
  • the connection status between the device and the external device needs to be obtained. If the connected external device is in a connected state, the target charging amount corresponding to the external device is continuously maintained, so that the charging device or the external power supply charges the device according to the target charging amount. In this way, the external device with a special resistance value needs to be continuously connected to the device during the charging process. The device determines whether it is connected to the external device by continuously measuring the resistance value, the power supply status or the communication status, etc. Once the connection is disconnected, the charging is restored to the default charging amount or stopped. This method has a simple logical judgment and is convenient to operate.
  • the external device is a cartridge.
  • the charging device during the charging process, it is only necessary to connect an external device with a specific resistance value, adjust the target charging amount and store the target charging amount.
  • the charging device or the external power supply charges the device according to the stored target charging amount and stops charging after reaching the target charging amount.
  • the aerosol provision device restores the original target charging amount by itself. In this way, there is no need for the external device to keep a connected state with the device all the time, which is more convenient to operate, and can prevent overcharging after the target charging amount is fully charged, which damages the battery performance.
  • a light-emitting element may be controlled to indicate the charging status.

  • the target charging amount of the device end is determined through the resistance value of the external device. It is possible to select external devices with different resistance values according to the charging requirements, so as to automatically match the target charging amount. There is no need for manual observation of the power, the operation is simple, and the charging amount standard can be unified to meet the production requirements without affecting the full-chargeable capacity during normal use by users.

Abstract

La présente demande concerne un procédé de commande de charge pour un dispositif de fourniture d'aérosol, un dispositif de fourniture d'aérosol et un système. Le procédé consiste à : obtenir la valeur de résistance d'un dispositif externe connecté au dispositif ; sur la base de la relation de correspondance entre la valeur de résistance et la quantité de charge, déterminer la quantité de charge cible correspondant à la valeur de résistance. Grâce aux modes de réalisation de la présente demande, le problème de la manière de régler automatiquement la quantité de charge cible en fonction des exigences de charge pour réduire les problèmes provoqués par des opérations manuelles est résolu.
