Abstract Regenerative braking is a technique that employs electric motors to convert the dynamic mechanical energy from motor’s spinning rotor and any attached loads into electricity. However, such type of regenerative can only slow but not stop vehicle because there too little excite motor acting as generator at low speeds. Therefore, this paper presents unique flywheel-based system for railwa...

Regenerative braking can extend the driving range and reduce PM emissions from abrasion for battery electric heavy-duty trucks (BETs). The composite control strategy including torque distribution dynamic coordinated four-axle BET equipped with electromechanical system is studied. A segmented proposed to maximize energy recovery while ensuring stability. simulation results reveal that shows bett...

The dual-motor EV (Electric Vehicle) is increasingly favored by manufacturers for its excellent performance in terms of power and economy. How to further reduce energy consumption make full use the recovery an important support improve overall vehicle economy realize “dual carbon” strategy. For architecture, motor model, battery loss model longitudinal braking force are established recovery-dom...

With the energy consumption rising in rail transport, the railway sector is showing increasing interest in the energy-efficient operation of freight trains. Freight trains require more complicated driving strategies than ordinary passenger trains do due to their heavy loads, especially in the long-distance steep downhill (LDSD) sections that are very common in freight rail lines in China. This ...

Most of the energy is wasted into heat due to conventional braking, so an optimal braking strategy needed. A Regenerative utilizes kinetic engine electrical by changing function electric machine a generator. The regenerative system uses Switched Reluctance Machine (SRM) which has several advantages; simple construction, does not require maintenance, and return battery. method that can be used i...
