The strategic management of a hybrid energy storage system (HESS) is a critical component of electric vehicle protection and performance. In this dissertation, model-based predictive control (MPC) and adaptive model-based predictive control (AMPC) are discussed. This dissertation also compares the PI, MPC, and AMPC controllers. The analogous circuit is used to define the proposed device and battery and supercapacitor model. The predictive model, the relationships it employs, as well as its design approach and the parameters it contains, are all discussed in the third section. Fourth, let's talk about it. We go through the findings as well as the battery and supercapacitor's dynamic life, device reliability, wasted system energy in all components, including the battery and supercapacitor, DC / DC, battery current rate and average battery energy, charge and discharge. Fifth, recommendations and issues for the future trend are discussed. Predictive control using an adaptive model can solve a strong nonlinear model and has time variability properties in a combined energy storage system, so it has advantages. It's worth noting that the cost-based predictive control feature is minimized to perform control operations at each level. The cost function is then applied to three tests after being derived from a standard quadratic (QP) problem. Different driving periods are observed. The predictive control based on the adaptive model, followed by the predictive control based on the explicit model, and finally the PI control, all perform better in terms of device efficiency and battery and supercapacitor maintenance. In the HWFET cycle, the AMPC controller increased battery life by 0.75 percent - 4.32 percent, in the UDDS cycle by 0.25 percent -9.24 percent, and in the US06 cycle by 5.31 percent -10.35 percent. In addition, the maximum battery current has been decreased from 26.5 to 67.6% on average. The square root of the battery current is reduced by 5.7-29.8%, the passing hour of the battery cell is reduced by 6.1-14.3 percent, and overall energy loss is reduced by 6.4 percent - 15.4 percent, while the supercapacitor's life is extended by up to 14.66 percent. In comparison to the numerous benefits listed above, the percentage has been destructive. In addition, the AMPC controller improved scrolling in the HWFET cycle 4.05 percent - 11.11 percent, the UDDS cycle 10.20 percent -25.79 percent, and the US06 cycle 0.75 percent -6.68 percent.
