However, most of these digital door locks use batteries (primary batteries) as batteries, and the battery consumption of digital door locks is occurring faster due to frequent use of doors with door locks and use of IoT functions or Bluetooth interlocking functions.

Most digital door lock products have 4 to 8 built-in batteries, and if operated 10 times a day, they can be used for only 6 to 10 months. Therefore, for digital door lock products that are used more frequently in a day due to a large number of people entering or having an IoT function or Bluetooth interworking function, users or administrators have to worry about replacing the battery frequently.

In addition, when it is time to replace the door lock battery and there is a warning alarm, if the replacement is not done in time and the battery is completely discharged, the digital door lock becomes inoperable. In such an embarrassing situation, the user or manager of the digital door lock purchases a 9V square battery and supplies current to the external emergency charging terminal of the digital door lock to temporarily operate the digital door lock (this is a method that is not well known), or a key maker You'll have to pay travel expenses to a repairman such as a retailer and get the digital door lock to work.

This work is cumbersome, inconvenient, and has to be paid for, so improvement is desired.

In addition, if a rechargeable secondary battery is used, it has the advantage of being able to use the battery in the battery compartment of the digital door lock by recharging it. Because it has to be recharged frequently, general users are reluctant to use it. Therefore, improvement is also desired.
