Regenerative Braking Strategy of Dual-Motor EV Considering Energy Recovery and Brake Stability

The dual-motor EV (Electric Vehicle) is increasingly favored by manufacturers for its excellent performance in terms of power and economy. How to further reduce energy consumption make full use the recovery an important support improve overall vehicle economy realize “dual carbon” strategy. For architecture, motor model, battery loss model longitudinal braking force are established recovery-dominated regenerative torque distribution (RBD) rule dual motors designed. Based on genetic algorithm (GA) theory taking into account SOC, speed intensity, a regenerative-braking optimization method proposed that integrates stability. intensity 0.3 initial 90 km/h selected verification. Compared with method, stability improved 22.8% 4.8%, respectively, under algorithm-based (GA-RBD) A variety conditions strategy validation result shows compared rule-based both as increase GA-RBD
