Description

이륜차용 스마트 배터리장치{Smart battery system for two-wheeled vehicles}Smart battery system for two-wheeled vehicles}

본 발명은 이륜차용 스마트 배터리장치에 관한 것으로, 특히 전기를 동력으로 사용하는 이륜차에서, 슈퍼커패시터와 리튬-인산철 배터리를 이용하여 일체형 배터리를 구현하고, 단일의 배터리 보호 회로를 이용하여 일체형 배터리의 충방전을 제어하여 시동성을 개선하고, 블루투스 연동을 통해 메인 배터리의 방전을 차단하여 이륜차의 잠금장치로 활용할 수 있도록 한 이륜차용 스마트 배터리장치에 관한 것이다.The present invention relates to a smart battery device for a two-wheeled vehicle, in particular, in a two-wheeled vehicle using electricity as power, an integrated battery is implemented using a supercapacitor and a lithium-iron phosphate battery, and a single battery protection circuit is used to protect the integrated battery. The present invention relates to a smart battery device for a two-wheeled vehicle that improves startability by controlling charging and discharging and blocks discharge of a main battery through Bluetooth interlocking to be used as a locking device for a two-wheeled vehicle.

최근 지구 온난화와 같은 환경문제에 대한 관심이 높아짐에 따라, 지구 온난화 원인의 주범인 이산화탄소 배출 감소 요구가 증가하고, 전기로 동력을 얻는 전기 이륜차에 대한 수요가 늘어나고 있다.Recently, as interest in environmental issues such as global warming has increased, demand for reducing carbon dioxide emissions, which is the main cause of global warming, has increased, and demand for electric two-wheeled vehicles powered by electricity has increased.

전기를 동력원으로 하는 원동기와 같은 전기 이륜차(이하, "이륜차"라고 명명함)는 대부분 납축전지를 이용하여 구동 전원으로 사용하고, 시동 및 주행을 제어한다.Most electric two-wheeled vehicles (hereinafter, referred to as "two-wheeled vehicles") such as motors using electricity as a power source use lead-acid batteries as a driving power source and control starting and driving.

그러나 납축전지를 이용한 이륜차 배터리는 장기간 사용시 자연 방전에 의해 시동성에 위착하며, 충방전 효율이 떨어지는 단점이 있다.However, two-wheeled vehicle batteries using lead-acid batteries have disadvantages in that startability is compromised due to natural discharge when used for a long period of time, and charging and discharging efficiency is low.

아울러 이륜차에서 방전시 시동을 위해 점프 스타터를 이용하기도 하는 데, 이 경우 점프 스타터는 납축전지와는 별개의 제품으로 구현되므로, 사용자입장에서는 납축전지가 장착되었음에도 시동을 위해 점프 스타터를 별도로 구입하게 되어, 추가 비용이 발생하고, 점프 스타터의 보관을 위해 별도의 보관 장치 등이 필요한 불편함이 있다.In addition, a jump starter is sometimes used to start a two-wheeled vehicle when it is discharged. In this case, the jump starter is implemented as a product separate from the lead acid battery, so the user has to purchase a jump starter separately for starting even though the lead acid battery is installed. However, additional costs are incurred and a separate storage device is required to store the jump starter, which is inconvenient.

따라서 이륜차에서, 시스템 자체적으로 시동성을 개선하여 점프 스타터를 추가로 구입하는 불편함 및 비용 낭비를 줄일 수 있는 이륜차의 배터리 장치가 요구되고 있다.Accordingly, there is a demand for a battery device of a two-wheeled vehicle that can reduce the inconvenience and waste of cost of additionally purchasing a jump starter by improving startability of the system itself in the two-wheeled vehicle.
