Regenerative braking in Plug-in Hybrid Electric Vehicles (PHEVs) significantly contributes to reducing emissions by capturing kinetic energy that would otherwise be lost as heat during traditional braking. Here’s how it helps:
- Energy Recovery and Reduced Engine Use: When the vehicle brakes, the electric motor acts as a generator, converting motion into electrical energy that is stored in the battery. This reduces the need to engage the gasoline engine, which in turn decreases both fuel consumption and the associated emissions.
- Operational Emissions Reduction: By allowing PHEVs to operate more frequently in electric mode, regenerative braking helps minimize tailpipe emissions. Since PHEVs produce no tailpipe emissions when running on electric power, increased reliance on stored energy contributes to cleaner air quality.
- Lower Carbon Footprint: By utilizing electrical energy generated from regenerative braking, PHEVs can reduce their carbon footprint, aligning with the goals of sustainable mobility by lowering overall greenhouse gas emissions during operation.
- Improved Fuel Efficiency: By recovering wasted energy and reducing reliance on the gasoline engine, regenerative braking enhances fuel efficiency, indirectly lowering emissions further by minimizing the engine’s operational time.
