Description

Battery Management System for Electric Transport Vehicle and Method for Managing the Battery The present invention relates to a battery management system for an electric transport vehicle and a battery management method, and more specifically, to a battery management system for an electric transport vehicle and a battery management method that collects state information of the battery of the electric transport vehicle and estimates the state in real time to efficiently operate the electric transport vehicle according to the remaining energy capacity of the battery, and monitors the temperature state of the battery to safely operate the electric transport vehicle. Generally, electric transport vehicles are mobile carts that utilize the drive of an electric motor and are widely used in industrial sites and rural areas. They are evolving from the conventional handcart type that carries cargo into a vehicle type that carries not only cargo but also passengers such as workers. A vehicle-type electric transporter is driven using electric energy and includes a vehicle body having multiple wheels, a steering unit for steering multiple wheels, a rechargeable battery provided in the vehicle body, and a driving unit for rotating multiple wheels. In other words, the electric transporter charges a rechargeable battery from an external power source and uses the electrical energy supplied from this battery to operate the drive unit, thereby rotating the wheels connected to the drive unit. However, such rechargeable battery-based electric transport vehicles have the problem that the battery status information must be checked frequently, and if the battery is discharged, work cannot be performed, so the user must charge it separately. In addition, if the battery of the electric transport vehicle is not properly cooled, there is a problem that safety accidents, such as the explosion of the battery pack due to overheating, may occur.
