The automotive industry has always been at the forefront of technological advancements, constantly evolving to meet environmental and consumer demands. As concerns about climate change and fuel consumption grow, automakers are looking for innovative ways to reduce energy waste and improve fuel efficiency. One such innovation gaining traction is the concept of automotive energy harvesting and regeneration.
By capturing energy that would otherwise be wasted—whether from vehicle movement, braking, or even the vehicle’s own mechanical systems—automotive energy harvesting and regeneration can play a significant role in enhancing vehicle performance, improving fuel efficiency, and lowering environmental impact. But how does it work? And what does the market look like for these technologies?
What Is Automotive Energy Harvesting and Regeneration?
Automotive energy harvesting and regeneration refer to the process of capturing and reusing energy that would otherwise be lost during a vehicle’s operation. These systems can harness kinetic, thermal, and even vibration-based energy to provide additional power or charge components within the vehicle.
Energy harvesting is an umbrella term for any method that captures energy from an external source, converts it, and stores it for later use. In the automotive world, energy regeneration is often linked to systems that convert kinetic energy back into usable power, like regenerative braking. These systems can work together to improve overall vehicle efficiency.
How Does Automotive Energy Harvesting and Regeneration Work?
Various types of energy harvesting technologies are being integrated into modern vehicles. Below, we’ll break down the most common and effective types:
1. Regenerative Braking
One of the most well-known and widely adopted forms of energy regeneration is regenerative braking. In traditional braking systems, kinetic energy (from the vehicle’s motion) is converted into heat and lost. However, in regenerative braking, the vehicle’s electric motor is used to slow down the car, capturing this kinetic energy and converting it into electrical energy, which is then stored in the battery for later use.
According to industry reports, regenerative braking is a standard feature in electric vehicles (EVs) and hybrid vehicles, with increasing adoption in conventional vehicles as well. This technology allows vehicles to recapture up to 70% of energy otherwise lost during braking.
2. Thermoelectric Generators
Another emerging technology in energy harvesting is the use of thermoelectric generators (TEGs), which convert heat energy into electrical power. In vehicles, TEGs can be placed near the exhaust system to capture heat from the engine and exhaust gases. This recovered heat can then be converted into electricity to power vehicle systems such as lights, air conditioning, or even to recharge the battery.
With increasing focus on fuel efficiency and reduced emissions, TEGs provide an opportunity to improve the overall energy profile of a vehicle by making use of energy that would otherwise be wasted.
3. Piezoelectric Systems
Piezoelectric energy harvesting uses mechanical strain or vibration to generate electricity. In the automotive sector, piezoelectric materials can be embedded in various parts of the vehicle, such as the suspension system or seat cushions. As the vehicle moves over uneven roads or experiences vibrations from other sources, these materials generate small electrical charges that can be captured and used to power sensors or other electronic devices.
This technology is still in its early stages but holds promise for improving the overall efficiency of vehicles in the future. Manufacturers are focusing on making piezoelectric systems more efficient and less costly, potentially leading to more widespread adoption in coming years.
