Description

Battery storage unit and battery compartment

The present invention relates to a battery storage device and a battery storage room, and more particularly, to a battery storage device and a battery storage room that allow the battery to be charged or stored when the battery is not in use.

In general, the battery may be mounted in most devices that require power, and the larger the battery capacity, the higher the energy density.

On the other hand, drones can receive power by mounting a battery, and when used for agricultural, commercial, military purposes, etc., a large-capacity battery with high energy density can be used, and the large-capacity battery can be expensive.

Using drones for agricultural purposes, for example, can be used for spraying pesticides, and multiple large-capacity batteries can be prepared with plenty of room depending on the size of the farmland and the amount of work.

In addition, these drones are frequently used during the busy season, but during the off-season, the battery is separated from the drone and stored.

In other words, agricultural drones are stored for several months without use during the off-season, and at this time, the battery needs to be separated from the drone and stored separately.

However, the person who manages the battery may be a person who does not have much knowledge about the battery, and if the storage method is wrong, a problem of a sudden decrease in battery life may occur.

In addition, while the battery is stored, it can be charged by connecting a commercial power source, but due to an unknown cause, the overcharge prevention protection circuit does not work and a fire may occur.

In addition, even if the battery is simply stored without being charged, residual power may remain in the battery, and such power may cause a fire.

In particular, in the case of a high-capacity battery with high energy density, when a fire occurs, it is difficult to extinguish it with a general fire extinguisher, so it has no choice but to wait until it is extinguished naturally.

On the other hand, as known through prior art documents, the conventional battery storage technology is equipped with a temperature sensor in the battery storage device, installs a cooling device such as a fan or an air nozzle, and when the set temperature is reached, the temperature sensor is high It detects and activates the cooling device.

However, as described above, a high-capacity battery with high energy density has a characteristic that fire occurs while rapidly rising in a short time when the temperature rises. There is a problem.

In addition, if a fire occurs in the battery storage device, various sensors and electrical/electronic devices may be damaged due to high temperature, which may make it difficult to operate even the cooling device normally. There is a problem that could be this.
