6. Regenerative Shock Absorber: Concept and
Working Principles
Concept: Regenerative shock absorbers aim to address the
energy inefficiencies of traditional shock absorbers by recovering
and reusing the kinetic energy generated during suspension
motion. They convert this energy into electricity, which can be
utilized for various purposes within the vehicle, contributing to
improved energy efficiency and reduced fuel consumption.
Working Principles: The working principles of regenerative
shock absorbers involve several key components and processes:
1. Suspension Motion
2. Energy Capture.
3. Energy Conversion.
4. Energy Storage
5. Energy Utilization

8. Overview of Regenerative Shock Absorber
Technology
1.Energy Capture Mechanism:
These shock absorbers are equipped with mechanisms designed to capture the kinetic energy
generated during suspension motion.
2. Energy Conversion and Storage:
The captured kinetic energy is converted into electrical energy using mechanisms like hydraulic
systems with integrated electric generators or electromagnetic generators. This electrical energy
is then stored in batteries or capacitors within the vehicle
9. 3. Energy Utilization:
The stored electrical energy can be used to power auxiliary systems within the vehicle, recharge the primary
battery, or provide additional power for acceleration and propulsion, thereby improving vehicle efficiency.
4. Components and Design:
These shocks include additional components for energy capture, conversion, and storage, such as
generators, hydraulic systems, and electrical connections. The design is more complex compared to
conventional shocks.
5. Impact on Vehicle Efficiency:
They have the potential to significantly improve vehicle efficiency by reducing energy waste and
enhancing fuel economy, especially in start-stop driving conditions.
6. Environmental Impact:
: By reducing fuel consumption, regenerative shock absorbers can lowergreenhouse gas
emissions and have a positive environmental impact.
10. How Regenerative Shock
Absorbers Work
1.Suspension Motion:
Regenerative shock absorbers are integrated into a vehicle's suspension system, just
like conventional shock absorbers. As the vehicle moves over uneven terrain, the
suspension system experiences vertical motion due to bumps, potholes, and road
imperfections.
2. Kinetic Energy Capture:
Within the regenerative shock absorber, there is a specialized mechanism for
capturing the kinetic energy generated during suspension motion. This
mechanism is typically based on one of two main principles:
a. Hydraulic System with Integrated Electric Generator:
b. Electromagnetic Generators
11. 3. Energy Storage:
The electrical energy generated is then stored within the vehicle.
4 Energy Utilization:
The stored electrical energy is harnessed to power various components and systems
within the vehicle.
5. Ride Quality and Safety:
It's crucial that the introduction of regenerative shock absorbers does not compromise
ride quality, handling, or safety. These shocks should maintain or enhance the vehicle's
suspension performance and safety standards
