Description

The present invention relates to an expandable mobile power supply device, particularly a portable device that is convenient for backup and charge / discharge, and can increase or decrease the total battery capacity based on usage needs. The present invention relates to an expandable mobile power supply device that can be charged or powered.

Portable digital devices such as mobile phone terminals, notebook computers, digital cameras, and music players all use a charge / discharge battery as a power source during use.

Generally, when charging a battery used in a portable digital device, a commercial AC power source is converted to a constant voltage level through a charger that is provided.
However, in an environment where a commercial AC power supply cannot be obtained, a situation in which charging becomes difficult or use of the portable device must be interrupted occurs.

Therefore, charging devices that are portable at any time are commercially available.
The portable power supply device allows the user to charge or supply power to the portable digital device even in an environment where there is no commercial AC power supply.

A conventional portable power supply device consists of a rechargeable battery and a control circuit and is housed together in a casing.
They are classified as products according to the size of the total battery capacity.
Portable power supply products with a small capacity have the advantage of being lightweight and compact, but have the disadvantage of short usage time.
Large-capacity portable power supply products are large, heavy, and inconvenient to carry, and the rechargeable battery has a limited use age and number of times. It must be discarded.
The present invention has been made in view of the above-mentioned drawbacks of conventional portable power supply devices.

  The problem to be solved by the present invention is that a battery unit is combined based on the user's needs for battery capacity, and the total battery capacity can be increased or decreased as necessary. To provide an expandable mobile power supply apparatus that can adjust the weight and, when necessary, improve the performance of the portable power supply apparatus by simply renewing the battery unit, and reduce waste of resources.

In order to solve the above problems, the present invention provides the following expandable mobile power supply device.
The expandable mobile power supply unit consists of a power control module and one or more battery units, and achieves the purpose of expanding battery capacity.
The power control module includes a circuit control board, an operation state indicator unit, a first connection port, a power input port, and a power output port.
A single battery unit includes a controller, a battery, a second connection port, and a third connection port.
When the control module is connected to the battery unit and energized, the battery unit is charged by the power input port of the control module, and backup power is stored.
If necessary, output power from the power output port of the control module to supply power to portable digital devices that require power,
The control module can charge one or several battery units, and can be easily attached and detached after the charging is completed, so that one or several battery units can be selected and used.
Although there is a problem with the circulation life of the battery, even if a single battery unit is damaged, it is not necessary to replace the entire battery unit, and it is only necessary to remove and replace or replace the damaged battery unit. Can be drastically reduced and can be used in consideration of the environment.

  The expandable mobile power device of the present invention can flexibly increase or decrease the total battery capacity by combining battery units based on the user's battery capacity needs. It can be adjusted, and when necessary, simply renewing the battery unit can improve the performance of the portable power supply and reduce waste of resources.
