The charging technology of electronic cigarette batteries mainly involves charging methods, the application of fast charging technology, and safety protection mechanisms during the charging process, etc. The following is a detailed summary of these technologies:
First, charging method
Regular charging: Most e-cigarettes use USB chargers for regular charging. When charging, you need to plug the charger into the power socket, then insert one end of the charging cable into the output interface of the charger and the other end into the input interface of the e-cigarette. The charging time is usually between 30 minutes and 4 hours, depending on the battery capacity and the power of the charger.
Fast charging technology: Fast charging technology can charge a large amount of power to the battery of electronic devices in a relatively short time. In the field of e-cigarettes, fast charging technology has been applied. For instance, some disposable e-cigarettes can be charged to a relatively high level in a short time, and the charging time of fast-charging rechargeable e-cigarettes is also relatively short. Fast charging technology is mainly achieved by increasing voltage, current or both. However, attention should be paid to heat dissipation design and safety protection mechanisms to avoid accelerating battery aging or posing safety hazards.
Second, the safety protection mechanism during the charging process
Short-circuit protection: The short-circuit protection of electronic cigarettes is achieved by using the low-voltage reset function of the chip itself. When a short circuit occurs at the load end, the chip will reset and cut off the circuit to protect the battery and the device.
Overcharge protection: By taking the internal reference voltage of the chip as the input and using VDD as the reference, the voltage at the battery terminal is calculated in reverse. When the chip detects that the battery voltage is higher than a certain threshold, it will cut off the charging circuit between the charging terminal and the battery to prevent overcharging of the battery.
Third, charging precautions
Select the appropriate charger and charging cable: Chargers and charging cables that match the specifications of the e-cigarette device should be used to ensure the safety and efficiency of charging. Avoid using incompatible chargers or charging cables to prevent battery damage or potential safety hazards.
Avoid overcharging: Overcharging may cause problems such as battery overheating and leakage. In severe cases, it may even lead to a fire. Therefore, the charger and charging cable should be unplugged in time after the charging is completed.
Pay attention to the charging environment: During the charging process, keep the e-cigarette away from flammable items and ensure that the charging environment is well-ventilated. Avoid charging in high-temperature or humid environments to prevent damage to the battery.
