Since crude oil used in vehicles has increased by 71.5% [1], which is one of the reasons for the destruction of air pollution, it is aware of the energy-friendly energy consumption of the surrounding area, which is more likely to be used in the near future. According to forecasts by 2030, All-new manufactured cars will be electric cars, and since batteries cost only a third of the price of electric cars, future electric cars are cheaper. [2]Oil-driven cars have about 2,000 parts, and they consume energy and require frequent repairs, but electric cars have only 18 parts, saving more energy than petrol-powered vehicles. (Battery management system (BMS) is a system that performs the balance of battery cells. To be able to use it safely and with maximum performance. This indicates the state of use, which is an important indicator for the operating status of electric battery vehicles. is the ability to store the energy of the battery. This indicates how far you can run. And the battery's drive ability indicates the acceleration and maximum speed of movement. Operating status is evaluated and extended battery life[3], In electric battery vehicles (BEVs), only electric motors are powered by mobile vehicles and the electricity contained in batteries is the only power source. It also has complex operations, and the battery is highly uncertain caused by the user's driving behavior. This can result in a deterioration in many factors such as temperature, humidity, Load capacity and pressure etc. It requires good battery management, but there are still challenges in developing a battery management system. In terms of finding ways to assess the state of charge (SOC) and the state of health (SOH) of the battery to be close to the actual state of use, the concept of managing the battery system is used in electric bicycles. Easy to reach people Easy to carry, small size It is more convenient and easy to test than electric cars, and can be used in a variety of applications, such as exercise. It is used to drive at a distance closer than driving by car to improve the battery management system. Assessing usage status and reducing battery deterioration factors
