Opis:
Regenerative braking in electric or hybrid driven vehicles is now commonly used feature. Development of technologies of electrical machines, secondary energy sources, power electronics and control systems allows for more efficient using of this attribute. Regenerative braking system converts the kinetic energy of moving vehicles on this form of energy that you can store in a secondary source of energy. The most common form of energy after conversion is electricity, easy to store in batteries or supercapacitors. There also are known systems with storage of mechanical energy (high-speed flywheels with composite rotors). Drive systems with optional regenerative braking should take into account a number of aspects influencing the process. It is very important to maintain the stability of the vehicle movement during braking. Another important aspect is the cooperation of regenerative braking system with conventional, mechanical brake system of the vehicle driven by a single axis. Sizing of the electrical machine (or machines) is associated with the needs of the propulsion of the vehicle, which limits the amount of absorbed energy in the initial stage of braking. Individual elements of the system energy conversion efficiency chain complexity affect the energetic results of this process. On the energy, efficiency of the process of braking energy recovery affects string conversion efficiency in the individual components of the system. Regenerative braking is the important factor, which could improve electric vehicle market chances, particularly in the city or neighbourhood personal transport. The article contains a description of the technical and legal circumstances of the process of regenerative braking and energy aspects of this process.

Opis:
Regenerative braking is a technique that employs electric motors to convert the dynamic mechanical energy from the motor’s spinning rotor and any attached loads into electricity. However, such a type of regenerative braking can only slow but not stop the vehicle because there is too little energy to excite the motor acting as a generator at low speeds. Therefore, this paper presents a unique flywheel-based regenerative braking system for railway vehicles. This system is supposed to meet high safety and comfort expectations in all operating conditions. The braking action control of this system should allow braking of empty or loaded vehicles according to load, the anti-blockage braking action of wheels and prevent wheel-slide during braking or wheel slip during acceleration. The new regenerative braking system under development, like any kinetic energy recovery system, requires the application of continuously variable transmission. The essence of the new solution is to design and build this type of variable transmission using only one planetary gear controlled through the powertrain control module for an electric motor cooperating concurrently. This paper describes complete modelling and simulation realisation on a closed-loop servomotor drive, which cooperates with the variable transmission of the regenerative braking system based on the Scilab/Xcos environment.

Opis:
Electrical vehicles have the ability to partially recover some kinetic energy during braking. Kinetic energy is transformed into electric energy, which is fed to the battery by the control system and stored there for further use. The aim of this paper was to analyse the levels of energy recovered by an electric vehicle during braking at various speeds and with different braking intensities. The first phase of testing consisted of vehicle braking tests in real-life conditions. The registered speed profiles were then used as input data for the simulation software. The authors have also analysed the effect of the state of charge of the battery and of the vehicle’s load on the amount of energy recovered during braking. The performed simulation tests demonstrated that the level of recovered energy is significantly affected by the initial braking speed and by the force of pressure applied to the brake pedal. The amount of recovered energy is less affected by the state of charge (SOC) of the battery and by the vehicle’s load. Energy regeneration during braking is currently an important research topic. The efficiency of an electric vehicle depends on the range, which can be extended thanks to the additional energy recovered during braking maneuvers. The presented preliminary simulation results are intended to assess the level of energy recovery in electric vehicles. The authors are aware that a full, comprehensive analysis requires additional research using electric vehicles that will verify the results presented in the paper.

Opis:
For city and neighbourhood people transport, electric driven vehicle with advanced energy storage and electronic control system could be competitive for conventional transportation means. Advanced energy storage and full utilization of regenerative braking system leads to significant energy saving. Regenerative braking is particularly important in city traffic, where a lot of acceleration/braking cycles occur. Replacement of internal combustion engines driven cars with electric vehicles give various benefits: decrease of transport sector impact on climate warming by CO2 emission reduction and general human health condition increase by elimination of toxic exhaust gases components emission by passenger cars. Particular interest of EV research is focused on lithium based batteries and supercapacitors. Nano-Lithium-Titanate battery could be fully recharged in a very short time and current peaks have no damage impact on the battery. Such batteries have high Cycle Life value (25000) and long life calendar (20 years).Fast charging systems should be equipped with energy converter built inside charging station. The converter has to be based on intelligent control system, for charging parameters setting (stable voltage, charging current, charging time) for different electric vehicles. To estimating charge/discharge characteristic and regenerative braking effectiveness, a simulation in MATLAB environment has been performed based on factory parameters. Graphical simulations results are presented in the paper.

Opis:
In electric and hybrid vehicles, it is possible to recover energy from the braking process and reuse it to drive the vehicle using the batteries installed on-board. In the conditions of city traffic, the energy dissipated in the braking process constitutes a very large share of the total resistance to vehicle motion. Efficient use of the energy from the braking process enables a significant reduction of fuel and electricity consumption for hybrid and electric vehicles, respectively. This document presents an original method used to estimate the efficiency of the regenerative braking process for real traffic conditions. In the method, the potential amount of energy available in the braking process was determined on the basis of recorded real traffic conditions of the analysed vehicle. The balance of energy entering and leaving the battery was determined using the on-board electric energy flow recorder. Based on the adopted model of the drive system, the efficiency of the regenerative braking process was determined. The paper presents the results of road tests of three electric vehicles, operated in the same traffic conditions, for whom the regenerative braking efficiency was determined in accordance with the proposed model. During the identi-fication of the operating conditions of the vehicles, a global positioning system (GPS) measuring system supported by the original method of phenomenological signal correction was used to reduce the error of the measured vehicle’s altitude. In the paper, the efficiency of the re-cuperation process was defined as the ratio of the accumulated energy to the energy available from the braking process and determined for the registered route of the tested vehicle. The obtained results allowed to determine the efficiency of the recuperation process for real traffic conditions. They show that the recuperation system efficiency achieves relatively low values for vehicle No. 1, just 21%, while the highest value was achieved for vehicle No. 3, 77%. Distribution of the results can be directly related to the power of electric motors and battery capacities of the analysed vehicles.

The DC traction substations are usually composed of the 3-phase transformer and the output diodę rectifier. So, such deWces do not allow for energy recuperation from the DC side to AC 3-phase mains. The energy recuperation is demanded for regenerative braking of traction drives with pulse converters (inverters for induction motors and choppers for DC motors). In this paper four technical solutions (Fig. 4) allowing for braking energy recuperation are discussed. This can be considered as the modemisation of the existing traction substations in the railway and the municipal traction. Such solutions indicate for three profits: energy recuperation, mechanical brakes saving and enhanced ąuality of traction vehicle control. The proposed converters are compared indicating indMdual advantages and draw-backs. Additionally the method ofsimplified calculation of energy balance of consumed and recuperated energy in the traction network has been presented in Chapter 2.

Opis:
The article refers to the previous work of the authors, in which the model of traffic organization of cooperating trains including the optimization of the use of energy returned to the catenary was presented. In the presented article, the model was modified by changing the main control variable, which affects the efficient use of energy. Departure time was changed for the arrival time of the train to the stop or station. The optimization is done by controlling the arrival time to the station in the acceptable (scheduled) range while maintaining the scheduled departure time. This model assumed optimization using the interval halving method (bisection) to achieve the optimal solution. The modified optimization method has been implemented in the original model of railway traffic organization. It considers the optimal use of energy recovered during electrodynamic braking using the energy transmission strategy to the catenary, assuming the cooperation of a train pair and volume of all recovered energy and stop time at the station.

Wśród znanych i stosowanych w praktyce metod wymieniono wykorzystanie odzyskanej energii na nietrakcyjne potrzeby własne pojazdu, magazynowanie odzyskanej energii w zasobnikach (pokładowych lub stacjonarnych) i wykorzystywanie jej w razie potrzeby, transformację i zwrot odzyskanej energii do krajowej sieci zasilania, a także moż-liwość przesyłu odzyskiwanej energii z powrotem do sieci jezdnej i wykorzystanie jej przez inne pojazdy mające zapotrzebowanie na taką energię (np. w fazie rozruchu). Pokrótce omówiono zasady działania wymienionych metod, wskazano ich wady i zalety oraz podano przykłady zastosowania w praktyce.

This article presents a review of methods for management of energy gained from regenerative braking. Among known and applied methods, the following are specified: using the recovered energy for non-traction own needs of the vehicle, storing the recovered energy in energy storage system (on-board or stationary) and its later use when needed, transformation and return of the recovered energy to the domestic power grid, and also the possibility of transferring the recovered energy to the traction network and its use by other vehicles (e.g., in during their acceleration phase). The principles of these methods are shortly described, their advantages and shortcomings are pointed out, and the practical applications are given. In summary, it is concluded that it would be advantageous to combine these methods into an integrated system of energy regeneration and a general scheme of such a system is proposed.

Results of examining the braking energy recovery in a passenger car with a hybrid system driving the front wheels have been presented. The tests were carried out on a vehicle with a series-parallel system, which combined an internal combustion engine with an electric motor. Such a system makes it possible to change the electric motor operation mode so that it becomes a generator, which charges a high-voltage battery with the use of the vehicle braking energy. The battery charging current was measured at braking with various vehicle deceleration values. The algorithm of controlling the battery charging current, the share of the energy recovered in the total braking energy, and the power of the regenerative braking in relation to the total braking power demand were analysed. The instantaneous power demand at braking on a horizontal road with a low rolling resistance coefficient was determined. The share of the electric power in the energy balance of the braking process as well as the demand and recovery of energy during this process were examined.

Opis:
The greenhouse effect and overall climate changes are the main reasons for developing ecological powertrain units dedicated to road vehicles. An electrical drivetrain without using conventional combustion engines fueled by hydrocarbon fuels is an effective method to significantly reduce CO2 emissions from the fleet. It is particularly vital in 2020 emission regulations aspects, and continuously the number of vehicles increasing. In this paper battery electric drive system of a small size passenger car was analyzed in terms of two different drive modes in cooperation with two recuperative braking modes. The research was carried out with real driving condition test requirements and driving parameters recording. Based on data obtained from OBD signals, energy flow and torque distribution have been specified. In results, overall reducing energy consumption has been achieved with ECO mode compared to normal mode. Selection of the driving mode ECO has a positive impact on reducing the state of charge saving more than 5%, taking into account the whole RDC test; greater energy consumption reductions were observed in selected test areas.
