Compact Hybrid Powertrain Development for a Formula SAE Car: Packaging Optimization and Control Strategy

The design of hybrid power units for compact racing vehicles demands optimal use of limited space while ensuring performance and regulatory compliance. This work presents a methodology for integrating a parallel P0 hybrid system into a Formula Student single-seater, combining a 480 cc single-cylinder ICE and a 30 kW PMSM within the existing chassis envelope. The design process included volume analysis, mechanical and cooling system integration, and a modular Li-ion battery pack. An energy management strategy, optimized via Dynamic Programming, improved torque utilization and energy recovery, considering a race track lap simulation.
