Increasing concern about climate change, air pollution and petroleum resource depletion has led regulators to impose more stringent standards in the automotive industry, which accounts for 22% of global CO2 emissions. Battery Electric Vehicles (BEVs) are the most popular among the different alternatives proposed, but Fuel Cell Hybrid Electric Vehicles (FCHEVs) are regaining attention after a setback during the last decade. HEVs have two or more power sources that propel the vehicle. Consequently, Energy Management Strategies (EMS) play a key role in the performance of such vehicles because they seek to optimize power split between those sources to minimize fuel consumption.
