Analog simulation method for automobile storage battery sizing

ActiveCN106980725ASolve frequent power lossSolve the difficulty of starting the vehicleElectrical testingDesign optimisation/simulationElectrical batteryCharge discharge
The invention relates to an analog simulation method for automobile storage battery sizing. The method comprises the steps of (1) dividing a driving cycle into three working conditions including a parking working condition, a starting working condition and a driving working condition, and calculating charge-discharge situations and electricity demand situations of a storage battery under different working conditions; (2) inputting a rated capacity and an initial charge state of the selected battery, and simulating under NEDC (New European Driving Cycle) working conditions through a MATLAB (matrix laboratory); and (3) carrying out multiple cycles to obtain the capacity of the storage battery after one and a half years. According to the analog simulation method, all electricity demand working conditions, including the starting working condition, the driving working condition and the parking working condition of an automobile in the use process are fully considered; meanwhile, the influence of environmental factors is also considered, starting in the low temperature environment is added into simulation calculation so that a calculation result is accurate; in addition, a simulation process simulates the use condition of the storage battery in the whole life cycle, and one-sidedness caused by only consideration of a new battery is avoided. Meanwhile, the problems of frequent lack of electricity and difficult starting of the automobile and shortened life of the storage battery caused by improper storage battery sizing and cost waste caused by excessive battery capacity selection can be solved from the technical angle.
