Performance Analysis of an Electric Vehicle Battery Using Real-time Drive Cycles

The impact of electric vehicles (EV) in the next decade will only depend on battery performance under different degradation test conditions. Battery parameters with various limitations in the market need to meet customer requirements with Chroma regenerative test pack system built 17020. This study lists the ability to improve durability, performance, lifespan, and energy density tests for making the rechargeable batteries compatible. In addition, to determine the life expectancy of the lithium-ion batteries, the load variation pattern is examined and the test system obtains the real-time driving cycle and an equivalent Constant Power (CP) at different time intervals. Therefore, based on the drive cycle, after calculating the power, a constant current discharge is then determined with a time step of 5 m/s at 100% State of Charge (SOC), and in addition a drive cycle is a collection of data points that plots a vehicle speed versus time. Different nations and organizations are developing driving cycles to assess a vehicle's performance in a variety of ways, including fuel efficiency, an electric car's driving range, and pollutant emissions. The modeled vehicle is developed in MATLAB and analyzes are performed for the different driving cycle patterns. Therefore, the consequence of the EV dynamics model is to analyze the type of battery at different driving cycles and distances traveled by the vehicle for a given time. In addition, the constant power with different time and constant current discharge with constant time of 100% SOC is studied by knowing that the distance traveled by the vehicle in the instant charge is reliable by integrating the reference speed.
