Description

Power Bank The present invention relates to a power bank, and more specifically, to a power bank capable of providing high-quality power using waste battery modules for electric vehicles and capable of controlling the charging and discharging of waste battery modules according to the amount of power measured by an integrating power meter. The present invention was derived as a result of the research project titled 'Development of a 10kWh-class reusable battery for carbon reduction and energy circulation'. A power supply unit must be used to provide operating power to loads, including electronic devices. Such a power supply unit is equipped with an internal rechargeable battery and is designed to convert direct current (DC) from the battery into alternating current (AC) for supply to the load, or to convert DC to DC for supply to the load. However, since a large capacity is required to use loads such as electronic devices for extended periods, the operating time and the ability to use multiple loads simultaneously are inevitably limited by the capacity. Consequently, there is a growing need for power supply units with increased capacity by incorporating multiple batteries. Prior Art: Korean Published Patent 10-2023-0171505 The prior art relates to a "power bank using electric two-wheeled vehicle batteries," and discloses a power bank using electric two-wheeled vehicle batteries that can supply sufficient power to the load side by combining multiple electric two-wheeled vehicle batteries with different capacities and specifications from different manufacturers, including used ones, to increase the capacity. FIG. 1 is a diagram showing the configuration of a power bank according to an embodiment of the present invention. FIG. 2 is a configuration diagram of a power bank according to another embodiment of the present invention. FIG. 3 is a configuration diagram of a power bank according to another embodiment of the present invention. The present invention will be described in detail below with reference to the attached drawings. FIG. 1 is a diagram showing the configuration of a power bank according to an embodiment of the present invention. Referring to FIG. 1, the power bank (100) according to the present embodiment may include a housing (110), a battery module (120), an inverter unit (130), an integrated power meter (140), and a control unit (150). The housing (110) may have a predetermined space for arranging detailed components constituting the power bank according to the present embodiment. In the present embodiment, the housing may be formed in a rectangular shape, and the housing (110) may be divided by a shelf formed in the middle into a lower space where a battery module (120) is arranged and an upper space where an inverter unit (130), an integrated power meter (1140), and a control unit (150) are arranged. In the present embodiment, an AC input unit (111) that receives power from an external AC power source may be formed in the housing (110). The AC input unit may be electrically connected to the inverter unit (130). Additionally, an AC output unit (112) that outputs AC power to the outside from the power bank according to the present embodiment and a DC output unit (113) that outputs DC power to the outside may be formed in the housing (110). The AC output unit (112) may be electrically connected to the inverter unit (130). The DC output section (113) can be electrically connected to the battery module (120). The AC input section, AC output section, and DC output section can be implemented in various ways depending on the shape of the connection section of the connected device. For example, the AC output section (112) can be implemented in the form of a power outlet so that a power cord of a general electrical device can be connected. In addition, the DC output section (113) can be formed in a shape that allows a charging module for charging small electronic devices, such as USB type or C type, to be connected. The housing (110) can be placed outdoors and exposed to rain or sunlight. Therefore, the outer wall of the housing (110) can be formed in a sealed structure to ensure good waterproofing, and a cover section (114) covering the corresponding area can be separately formed in the parts of the AC input section (111), AC output section (112), and DC output section (113) formed in the housing. The above cover portion may be formed to cover the entire side where the AC output portion (112) and the DC output portion (113) are formed, or it may be formed to cover the AC output portion (112) and the DC output portion (113) individually. In this way, a separate cover portion is formed at the part where the exterior and interior of the housing are connected to ensure the waterproofing function of the housing. The battery module (120) is placed in the lower space of the housing and multiple waste batteries for electric vehicles can be connected. In the power bank according to this embodiment, the battery
