To gain a deeper understanding of the regenerative braking system and to demonstrate its operation in a practical setting, a regenerative braking simulation system was developed. The mechanical components of the system were designed first, including the calculation of the flywheel group, motor selection, hydraulic pump selection, and accumulator selection. Following this, a control system based on a data acquisition card was designed, encompassing both hardware and software elements. This system is capable of collecting data such as flywheel speed and accumulator pressure, as well as controlling the electromagnetic clutches. Subsequently, experiments were conducted using the developed system. The experimental results indicate that the maximum accumulator pressure reached 15.5 MPa when the initial flywheel speed was 796 rpm, while it only reached 8.8 MPa at an initial speed of 296 rpm. This demonstrates that more energy can be recovered at higher initial speeds. Moreover, the results confirm that the designed control system effectively manages the energy recovery process and facilitates the demonstration of the regenerative braking process. The proposed system offers a valuable platform for studying vehicle regenerative braking systems.
