AI Customer ServiceWe can classify the energy-storing devices used for regenerative vehicle braking into three categories: hydraulic energy storage devices (HES), flywheel energy storage devices , and electric energy storage devices [9, 10].
The purpose behind the introduction of RBSs is to recover a vehicle's kinetic energy during braking, energy which would otherwise be dissipated as heat. Recovering even a portion of a vehicle's kinetic energy and redirecting it towards the ESS would make more energy available for the vehicle to consume.
The device is disposed concentrically about a shaft and secured to the shaft on one end, whereas the other end is free to rotate and can be torsionally stressed to store energy upon braking and released from a fixed reference during vehicle start-up. This patented design made use of CVT to govern the energy the transfer to/from the storage device.
There are various energy capturing devices that are suitable to be used in regenerative braking systems. The flywheel is a device that when rotated, can store kinetic energy during braking. The ultracapacitor is the most commonly adopted device in regenerative braking systems. The ultracapacitor temporarily stores electrical charge.
Currently, the focus of research on braking energy recovery technology is mostly on enhancing the efficiency of recovering energy from vehicle brakes by allocating the braking force in a rational manner. The literature categorizes the driver’s intentions for driving based on the pedal aperture and the pace of brake pedal movement.
When the regenerative braking feature is activated, the propulsion engine transforms a portion of the kinetic energy into electrical energy. This brake energy is then stored in the battery through the inverter, resulting in improved energy efficiency and increased driving range.
