A holder, a positive electrode plate connected to the lower part of the electrode plate holder and having a positive polarity, a negative electrode plate connected to the lower part of the electrode plate holder and having negative polarity and one more electrode plate than the positive electrode plate, an internal terminal installed on the upper part of the electrode plate holder, the interior A connector that connects a terminal and other internal terminals in series and can be separated, and when the internal terminals are connected in series by the connector, each external terminal and the external terminal are in contact with internal terminals at both ends having different polarities.

It relates to a vehicle battery capable of electrolyte exchange, characterized in that:
일반적으로 차량용 배터리는 전기차가 아닌 이상 납산 배터리가 주로 사용된다.In general, lead-acid batteries are mainly used for vehicle batteries, unless they are electric vehicles.
상기 납산 배터리는 150년 전 최초로 프랑스에서 개발된 기술이지만 지금까지 사용되고 있으며, 이는 해당기술의 안정성이 뛰어날 뿐만 아니라 가성비 측면에 있어서도 우수하다는 것을 알려준다.Although the lead-acid battery was first developed in France 150 years ago, it is still used to this day, which shows that the technology is not only excellent in stability but also excellent in terms of cost-effectiveness.
하지만, 아무리 안정성이 뛰어나다 할지라도 차량의 운행시에는 각종 전장부하들이 온/오프 되거나, 그 사용상태가 달라지면서 전장부하들의 부하 변동이 빈번하게 일어나기 때문에, 차량 전기 계통 폐회로 상에서의 전류는 수시로 불안정한 상태에 놓이게 되며, 납산 배터리는 일반적으로 전해액에 묽은 황산을 채택함으로 오랫동안 사용하면 황결정이 생기거나 극판이 부식되는 등의 문제가 있다.However, no matter how excellent the stability, the current in the closed circuit of the vehicle's electrical system is often unstable because various electrical loads are turned on/off or their usage status changes and the load on the electrical loads changes frequently. Lead-acid batteries generally use dilute sulfuric acid as the electrolyte, so when used for a long time, there are problems such as the formation of sulfur crystals or corrosion of the electrode plates.
이러한 문제를 해결하기 위해 종래기술로 국내등록특허 제10-1791082호가 제시된바 있다.To solve this problem, Domestic Patent No. 10-1791082 has been proposed as a prior art.
상기 종래기술은 내부가 복수개의 셀 공간으로 구획되어 있는 케이스와, 셀 공간에 충전되는 전해액과, 전해액이 충전된 각 셀의 내부 공간에 마련되는 격리판과, 격리판에 의해 구획된 각 공간에 설치되는 양극 단자 및 음극 단자와, 양극 단자 및 음극 단자와 각각 전기적으로 연결되며 케이스의 외부로 노출되어 있는 양극 터미널 및 음극 터미널과, 양극 단자 및 양극 터미널 사이와 상기 음극 단자 및 음극 터미널 사이 중 적어도 하나의 단자 및 터미널 사이에 전해액과 비접촉하도록 마련되며 원적외선 방사부를 갖는 부스터를 포함한다.The prior art includes a case whose interior is divided into a plurality of cell spaces, an electrolyte filled in the cell space, a separator provided in the inner space of each cell filled with the electrolyte, and each space partitioned by the separator. At least one of the installed positive and negative terminals, the positive and negative terminals respectively electrically connected to the positive and negative terminals and exposed to the outside of the case, and between the positive and positive terminals and between the negative and negative terminals. It is provided between one terminal and a booster having a far-infrared radiation portion and is provided to be non-contact with the electrolyte.
상기 종래기술은 불안정한 전류에 의해 전장부하들의 작동성능을 저하시켜 연비를 포함한 차량의 효율의 감소되는 것을 방지하는 것이나 납산 배터리 자체의 고장에 대한 해결책은 제시되지 못하였다.The prior art prevents a decrease in vehicle efficiency, including fuel efficiency, by deteriorating the operating performance of electrical loads due to unstable current, but does not provide a solution to the failure of the lead-acid battery itself.
통산 차량용 배터리는 묽은 황산을 전해액(황산 : 38%, 비중 : 1.280)으로 하여 이산화납(PbO2)과 납(Pb)을 담그면 이온화 경향이 큰 금속인 이산화납이 음극성을 띄고, 이온화 경향이 적은 납이 양극성을 띄게 되어 화학반응에 의해 2V의 기전력이 발생한다.In general vehicle batteries, when lead dioxide (PbO 2 ) and lead (Pb) are immersed in dilute sulfuric acid as an electrolyte (sulfuric acid: 38%, specific gravity: 1.280), lead dioxide, a metal with a high tendency to ionize, becomes negative and has a tendency to ionize. A small amount of lead becomes positive and an electromotive force of 2V is generated through a chemical reaction.
상기 화학식1과 같이 통상적인 차량용 배터리는 오랜 기간 동안 충전 및 방전사이클을 거치는 동안 두 극판에 단락이 발생하거나 전해액의 비중이 낮아지거나 전해액속의 불순물(황결정, 가스 등)에 의한 극판손상 등의 다양한 원인에 의하여 충전 및 방전기능이 원활하게 이루어지지 않을 경우 수명이 다하여 교체를 해야 한다.As shown in Formula 1 above, a typical vehicle battery may suffer from various types of damage, such as a short circuit between the two electrode plates, a decrease in the specific gravity of the electrolyte, or damage to the electrodes due to impurities (sulfur crystals, gas, etc.) in the electrolyte during charging and discharging cycles over a long period of time. If the charging and discharging functions are not performed smoothly due to some reason, the product has reached the end of its life and must be replaced.
하지만, 현재에 대부분 배터리 교환방식은 배터리 전체를 새로운 제품으로 교체해야 한다는 점에서 사용자에게 비용적인 부담을 안겨주고 있다.However, most current battery replacement methods impose a cost burden on users in that the entire battery must be replaced with a new product.
그로 인해, 사용자가 직접 교체할 수 있으면서도 부분적으로 전해액만 교환하거나 극판만을 따로 교체하는 것이 가능한 차량용 배터리의 필요성이 대두되었다.As a result, the need for a vehicle battery that can be replaced directly by the user has emerged, allowing only the electrolyte to be partially replaced or only the electrodes to be replaced separately.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로 그 목적은 차량용배터리의 고장 시 전해액만 교환하거나 문제가 생긴 극판만을 따로 교체할 수 있는 차량용 배터리를 제공하는데 있다.The present invention is intended to solve the above problems, and its purpose is to provide a vehicle battery that can replace only the electrolyte or separately replace the problematic electrode plates when the vehicle battery fails.

A holder fixing socket (12) fixed to the holder fixing socket (12), an electrode holder (43) fixed to the holder fixing socket (12), a positive electrode plate (42) connected to the lower part of the electrode plate holder (43) and showing positive polarity, and the electrode plate holder (43) A negative electrode plate 41 that is connected to the lower part and has negative polarity and is installed with one more electrode plate than the positive plate 42, an internal terminal 44 installed on the upper part of the electrode plate holder 43, the internal terminal 44, and A connector 30 that connects other internal terminals 44 in series and can be separated, and when the internal terminals 44 are connected in series by the connector 30, the internal terminals 44 at both ends have different polarities. ) and each external terminal 22 in contact with the external terminal 22 is installed and includes a case cover 20 that protects the battery from the external environment.
이 때, 상기 배터리케이스(10)의 내부는 6개의 격실을 구성하고, 각 격실마다 2V의 기전력을 발생시키는 것을 기준으로 직렬연결 하여 총 12V의 기전력을 차량의 공급한다.At this time, the inside of the battery case 10 consists of six compartments, which are connected in series on the basis that each compartment generates an electromotive force of 2V to supply a total electromotive force of 12V to the vehicle.
