Principle of energy storage brake

How does electric braking work?

When drivers apply the brakes, the electric motor reverses its function, capturing kinetic energy typically lost as heat in conventional friction braking systems. This energy is converted into electrical energy and stored in the vehicle’s battery.

Why is a braking system important?

Even though the goal of an RBS is to recuperate as much kinetic energy as possible during braking processes, it is also crucial for the system to decelerate the vehicle safely and comfortably. Brake safety and stability are major criteria in evaluating RBSs , , .

How does a braking system work?

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.

What are regenerative braking systems (RBS)?

Consequently, attention on minimizing the impacts of this industry have led to the development of kinetic energy recovery systems known as regenerative braking systems (RBS). RBSs facilitate kinetic energy recuperation through vehicle braking processes, thus avoiding the usual dissipation of energy (heat) due to friction-based brake pads.

How does regenerative braking work?

During regenerative braking, the electric motor, which typically propels the vehicle, transitions to an inverter mode. It converts the vehicle’s mechanical energy back into electrical energy. This transition is facilitated by the onboard control system, which detects the need to reduce speed and accordingly adjusts the motor’s function.

How does a hydraulic braking system work?

The operation of the entire system is governed by the vehicle's control unit. Fig. 6 represents a simplified schematic representing the energy flow of a hydraulic-based RBSs . During braking processes, the hydraulic motor/pump operates as a pump.
