6 FAQs about [Automobile shock absorber energy storage device]
How can regenerative shock absorbers improve fuel efficiency?
In theory, by regenerating braking energy, maximum fuel efficiency can be increased by 30%, and efficiency can be further improved by 10% by recovering the vibration energy in suspension systems . Energy regenerative shock absorber (ERSAs) that scavenge vibration energy are considered one of the most promising methods.
Can shock absorbers be used for energy harvesting and vehicle dynamics?
In the literature, researchers performed analyses of energy harvesting and vehicle dynamics by replacing conventional shock absorbers with RSA. The RSA can be installed for energy regeneration in all on-road vehicles; however, the amount of energy harvested depends on road conditions and vehicles.
Can regenerative shock absorbers extend the battery endurance of an EV?
Whereas existing regenerative shock absorbers mainly focus on the methods of energy harvesting, there is no such regenerative shock absorber for use in extended range EVs. In this paper, we present a novel high-efficiency energy regenerative shock absorber using supercapacitors that is applied to extend the battery endurance of an EV.
Are hydraulic shock absorbers suitable for heavy vehicles?
Hydraulic RSAs are suitable for heavy vehicles and can be installed instead of all conventional shock absorbers with a standard generator module. However, hydraulic RSA has a low energy harvesting efficiency and higher energy losses in the hydraulic circuits.
How do shock absorbers work?
The working principle involves replacing traditional shock absorbers with a ball screw mechanism. When the shock absorber moves back and forth along a bumpy road surface, the ball nut moves up and down horizontally, driving the screw and motor to rotate forward and backward and converting energy into electrical energy.
Do shock absorbers save energy?
Several studies reported that conventional shock absorbers are liable for 30% of energy dissipated at wheel systems, which is approximately 10% of the total vehicle fuel consumption (Abdelkareem et al. 2019). The RSA can recover waste vibration energy from the suspension system while reducing the vibrations (Cai and Zhu 2022).
