As urban congestion increases, energy recovery during braking has become critical. Regenerative braking systems capture kinetic energy lost during deceleration and convert it into electrical energy, stored in batteries for future use. This enhances fuel efficiency and reduces reliance on engine braking, particularly in Electric Vehicles (EVs), Plug-in Hybrid Electric Vehicles (PHEVs), and Hybrid Electric Vehicles (HEVs).
These systems demonstrate 60–70% energy recovery efficiency, which significantly boosts vehicle performance while minimizing environmental impact. With electrification becoming mainstream, regenerative braking is transitioning from a niche innovation to a standard feature in modern vehicles.
Technologies such as electric turbochargers and exhaust gas recirculation systems help recover waste energy from engine heat and exhaust. This recovered energy can be repurposed to power vehicle systems or stored, increasing fuel efficiency and reducing emissions in both gasoline and diesel-powered vehicles. These systems are especially vital for Fuel Cell Electric Vehicles (FCEVs), which aim to meet zero-emission targets set by regulatory bodies.
Technological advancements in waste energy recovery are transforming the automotive landscape. Automakers are leveraging innovations in valve blocks, heat exchangers, and smart controllers to boost the energy utilization of internal systems. This trend is particularly prominent among leading suppliers like Brembo and Sensify, which are optimizing subsystems for EV efficiency.
Government mandates on carbon emission reductions and incentives for improved fuel economy are accelerating the integration of advanced AERS into mainstream vehicle designs. Additionally, the ability to use recovered energy for auxiliary systems like air conditioning, infotainment, and lighting reduces engine load and extends driving range.
Despite the benefits, the high cost and complex installation of energy recovery systems present substantial barriers. These systems require advanced electronics, controllers, and integration with vehicle powertrains, resulting in elevated manufacturing and aftermarket costs. Furthermore, the evolving standards and R&D demands add to the operating expenses for automakers and suppliers.
This complexity discourages smaller OEMs and consumers, although long-term operating cost savings and regulatory compliance are expected to outweigh the initial investments.
The regenerative braking system segment is projected to experience robust growth during the forecast period. Valued at USD 8.77 billion in 2018, it continues to gain traction due to rising EV and HEV adoption. Automakers are increasingly integrating regenerative braking into both gasoline and diesel models to reduce fuel dependency and emissions.
Turbochargers capture exhaust energy to increase engine power and efficiency. These systems are crucial in light trucks, electric passenger vehicles, and commercial vehicles, especially in North America, where demand for performance and emission control is high.
EGR systems reduce nitrogen oxide emissions by recirculating a portion of the exhaust gas back into the engine’s intake. This not only lowers emissions but also improves engine efficiency in hybrid and combustion-engine vehicles.
The rising demand for electric passenger cars, electric school buses, and light trucks is driving AERS integration across these vehicle types. With EVs becoming more mainstream and infrastructure improving, energy recovery systems are becoming a key differentiator in vehicle performance.
