배터리 충전장치{Battery charging device}Battery charging device {Battery charging device}

본 발명은 배터리 충전장치에 관한 것으로서, 더욱 상세하게는 파우치형 또는 박막형 배터리배터리를 다중으로 충전할 수 있는 배터리 충전장치에 관한 것이다.The present invention relates to a battery charging device, and more specifically, to a battery charging device capable of multiple charging pouch-type or thin-film battery batteries.

최근, 노트북, 비디오 카메라, 휴대용 전화기 등과 같은 휴대용 전자 제품의 수요가 급격하게 증대되고, 전기자동차, 에너지 저장용 축전지, 로봇, 위성 등의 개발이 본격화됨에 따라, 반복적인 충방전이 가능한 고성능 이차 전지에 대한 연구가 활발히 진행되고 있다. Recently, as the demand for portable electronic products such as laptops, video cameras, and portable phones has rapidly increased, and as the development of electric vehicles, energy storage batteries, robots, and satellites has begun, high-performance secondary batteries capable of repeated charging and discharging have been developed. Research is actively underway.

현재 상용화된 이차 전지로는 니켈 카드뮴 전지, 니켈 수소 전지, 니켈 아연 전지, 리튬 이차 전지 등이 있는데, 이 중에서 리튬 이차 전지는 니켈 계열의 이차 전지에 비해 메모리 효과가 거의 일어나지 않아 충 방전이 자유롭고, 자가 방전율이 매우 낮으며 에너지 밀도가 높은 장점으로 각광을 받고 있다.Currently commercialized secondary batteries include nickel cadmium batteries, nickel hydrogen batteries, nickel zinc batteries, and lithium secondary batteries. Among these, lithium secondary batteries have little memory effect compared to nickel-based secondary batteries, so they can be freely charged and discharged. It is receiving attention for its extremely low self-discharge rate and high energy density.

이러한 리튬 이차 전지는 주로 리튬계 산화물과 탄소재를 각각 양극 활물질과 음극 활물질로 사용한다. 리튬 이차 전지는 양극 활물질과 음극 활물질이 각각 도포된 양극판과 음극판이 세퍼레이터를 사이에 두고 배치된 전극 조립체와, 전극 조립체를 전해액과 함께 밀봉 수납하는 전지 케이스를 구비한다.These lithium secondary batteries mainly use lithium-based oxide and carbon material as positive and negative electrode active materials, respectively. A lithium secondary battery includes an electrode assembly in which a positive electrode plate and a negative electrode plate each coated with a positive electrode active material and a negative electrode active material are disposed with a separator in between, and a battery case that seals and stores the electrode assembly together with an electrolyte solution.

일반적으로 리튬 이차 전지는 외장재의 형상에 따라 전극 조립체가 금속 캔에 내장되어 있는 캔형 이차 전지와 전극 조립체가 알루미늄 라미네이트 시트의 파우치에 내장되어 있는 파우치형 이차 전지로 분류될 수 있다. In general, lithium secondary batteries can be classified into can-type secondary batteries in which the electrode assembly is built into a metal can and pouch-type secondary batteries in which the electrode assembly is built in a pouch of an aluminum laminate sheet, depending on the shape of the exterior material.

파우치형 이차 전지는 전극 조립체와, 전극 조립체를 수용하는 파우치 외장재로 이루어지는 것이 일반적이다. 여기서, 전극 조립체는 양극판과 음극판을 구비하며, 양극판과 음극판 사이에는 세퍼레이터가 개재된다. 그리고, 양극판과 음극판에는 각각 양극 탭과 음극 탭이 구비되고, 양극 탭과 음극 탭은 각각 양극 리드 및 음극 리드와 결합되며, 양극 리드와 음극 리드의 일부는 파우치 외장재의 외부로 노출됨으로써 외부 장치와 전기적으로 연결되는 전극 단자를 제공한다.A pouch-type secondary battery generally consists of an electrode assembly and a pouch exterior material that accommodates the electrode assembly. Here, the electrode assembly includes a positive electrode plate and a negative electrode plate, and a separator is interposed between the positive electrode plate and the negative electrode plate. In addition, the positive and negative electrode plates are provided with positive and negative tabs, respectively, and the positive and negative tabs are combined with the positive and negative leads, respectively. Parts of the positive and negative leads are exposed to the outside of the pouch exterior material to protect against external devices. Electrode terminals that are electrically connected are provided.

그러나, 종래에는 소비자가 필요에 따라 파우치형 이차 전지를 구매하는 경우 파우치형 이차 전지를 충전할 수 있는 전용 충전장치가 없고 어 파우치형 이차 전지의 사용이 매우 불편하고 까다로운 문제가 있다.However, conventionally, when a consumer purchases a pouch-type secondary battery as needed, there is no dedicated charging device for charging the pouch-type secondary battery, and the use of the pouch-type secondary battery is very inconvenient and difficult.
