Development of Different Control Strategies for Hybrid Energy Storage Systems in Electric Vehicles

High electric traction motors are engaged in the electric vehicles in order to deliver required high torque to the vehicle to maintain the essential torque. Generation of high torque require high amount of current to be delivered at the traction motors. In the existing system power pack in the form of lithium-ion battery is engaged to provide the required power to the traction power. The continuous high traction power delivery causes multiple problems like aging mechanism causing speedy worsening of the battery performance and even sometimes causes thermal runaway. Hybrid energy storage system is the way to address this issue in an effective way. The present research work is the verified means for providing constant energy source for high power delivery to the traction motors. In the research work multiple energy sources like lithium-ion battery source, fuel cell and ultra capacitor are used for development of the hybrid energy source. These energy sources are intelligently engaged through different control strategies in order to ensure confirmed required power delivery at the traction motors. Different modules from the Simulink are used for the development and analysis of the targeted system.
