Development of the Electrically-Controlled Regenerative Braking System for Electrified Passenger Vehicle 2013-01-1463

As one of the key technologies of electrified vehicles, regenerative braking offers the capability of fuel saving by converting the kinetic energy of the moving vehicle into electric energy during deceleration. To coordinate the regenerative brake and friction brake, improving regeneration efficiency and guaranteeing brake performance and brake safety, development of special brake systems for electrified vehicles is needed.
This paper presents a new type of electrically-controlled regenerative braking system (EABS) that has been developed for electrified passenger vehicles, which has the potential to be brought into production in China. By utilizing as much as possible mature components, integrating cooperative regeneration with ABS/TCS functions, EABS can achieve high regeneration efficiency and brake safety while providing system reliability, low development cost and development risk. This article describes the layout of the newly developed regenerative braking system. The operation modes and control methods of the system are introduced. Road test data from a commercialized electric vehicle prove the good performance of this system. The energy consumption of vehicle reduced by EABS developed is over 25% under ECE driving cycle.
