Design of Regenerative Braking System and Energy Storage with Supercapacitors as Energy Buffers

Vehicles are part of urban area transport and are subjected to variable loads as they traverse the city with varying slopes and stop-and-go traffic. Electric Vehicles (EVs) can be a good option because of their high efficiency under stop-and-go conditions and ability to gain energy from braking. However, limited battery energy makes EVs less efficient and degrades their lifetime. In contrast to a Li-Ion battery, supercapacitors work well under high power charge and discharge cycles. However, their high cost and low energy density prevent them from being viable replacements for batteries. Due to the slow charging and discharging process of batteries, they have a low power density, but a high energy density compared to the supercapacitor. In this paper, we discussed our system design consisting of both a battery and a supercapacitor. The main aim is to design and develop a scheduling algorithm to optimize energy flow between the battery, supercapacitor, and motor. We further described an analogue-based control methodology and algorithm for the supercapacitor, augmented battery-powered motoring process. This is in addition to a charge controller designed to optimize the supercapacitor bank's current-based charge-discharge profile. The system design and tests are developed on PSPICE and a hardware platform.

Dynamic Coordinated Control for Regenerative Braking System and Anti-Lock Braking System for Electrified Vehicles Under Emergency Braking Conditions

The economy of electrified vehicles can be improved by using the motor to recover the energy released during braking. However, the vehicle’s regenerative braking system (RBS) and anti-lock braking system (ABS) are not compatible, so the energy dissipated during braking cannot be recovered under emergency braking conditions. This paper employs the method of logic threshold control combined with phase plane theory to analyze the relationship between the slip rate and the braking torque during the ABS braking process and to obtain the composition rule of the braking torque required for ABS braking. Based on this rule, a control strategy to coordinate RBS and ABS when triggering ABS is proposed to improve the efficiency of braking energy recovery. Furthermore, a comparative simulation is conducted to analyze the braking performance of electrified vehicle on roads with different adhesion coefficients by adopting the proposed control strategy and the traditional control strategy. The results show that, compared with the traditional coordinated control strategy, the braking energy recovery efficiency of the proposed coordinated control strategy is improved by 23.08%-38.54%, and can effectively shorten the braking distance and braking time, with better braking performance. Therefore, this paper offers a useful theoretical reference to the design of RBS and ABS coordinated control strategies for electrified vehicles.

A novel method for the design of regenerative brake system in an urban automotive

Environmental problems a nd fossil fuel limitations have made the automobile manufactures use renewable energies and energy recovery systems; therefore, particular attention has been paid to hybrid vehicles and/or biofuel vehicles. In this paper, the main objective is to study the appropriate strategy for choosing a better alternative to fossil fuels. Here, one of the strategies is using some devices in order to reduce the waste energies and the other is providing the condition in order to reuse the energies. For this purpose, the regenerative braking system could be mentioned as an energy recovery mechanism which slows a vehicle down by converting its energy into another form, which can be either used immediately or stored until needed. In this work, the design of regenerative braking system in hybrid vehicles has been considered and conducting a few tests, based on ISO 6469 standards; recycled energy at different speeds has been investigated. Also comparison of brake distance of this vehicle in two conditions, with and without regenerative braking has been made. The results show that this system is suitable in high speeds, but in low speeds conventional braking system has better efficiency.

Regenerative Braking System for a Pure Electric Bus

A design of regenerative braking system (RBS) for a pure electric bus was presented in this paper. A design of regenerative braking system for a pure electric bus was presented in this paper The control of regenerative braking was achieved by Pneumatic ABS and improve braking energy recovery under the premise of ensure braking performance. Regenerative braking control algorithm was mainly composed of two parts for the identification of the drivers intention and the brake force distribution. The regenerative brake control model was built in the matlab/simulink environment, rapid prototyping control was achieved by Autobox and vehicle test was carried on. Result shows that the control strategies can effectively make the pneumatic brake system and motor brake system work harmoniously.

According to the regenerative braking system(RBS) with a pedal emulator as well as the control strategy. Design a hardware test platform of power regenerative system and the scheme of software experiment. Aim at the control strategy, braking safety and braking feeling of RBS with a braking pedal emulator is confirmed via hardware in loop (HIL) test. A high regenerative rate is obtained. From the result of simulation, the pedal force line from RBS with a pedal emulator is between the envelope curve of the pedal force from conventional vehicle. Actual wheel cylinder pressure can follow the change of target pressure very well. The regenerative braking rate reaches 53%.
