Opis:
Permanent magnet motors are more and more frequently used in various applications. In this group motors with a trapezoidal EMF deserve a special attention. They are characterized by a simple construction, high efficiency and high torque overload. A certain drawback of BLDC motors are difficulties with an operation at a speed above the nominal value. The article presents the results of investigations into the variablestructure electronic commutator designed for the drive of a small electric vehicle equipped with BLDC motors. Such a solution allows extending the standard range of the drive's speed. The considerations contained in the article focus on the possibilities and effects of regeneration mode in the proposed topology of converter. A theoretical analysis has been presented as well as computer simulations carried out by means of Matlab- Simulink, which were then verified at a laboratory. The tests were finished with trias conducted using a small electric vehicle Elipsa.

Opis:
Energy recovery systems are increasingly being used in modern cars equipped with the internal combustion engine. This is because such an arrangement allows the recovery of part of the energy without the need for additional mounting on the vehicle electric motors and batteries high capacity. But the question about the limits of applicability of such a solution. restrictions are in this case the conditions for the movement of the car and the total power of electricity consumers in the vehicle. Depending on these factors, it is appropriate accessories car system recuperation of more or less power. The article presents the results of simulations of various systems for a variety of urban traffic. For that purpose road tests made with a view to representing the motion of various utility in terms of energy recovery. For each type of movement performed to optimize system parameters. On this basis, we discussed the legitimacy of the use of systems with different power.
Układy rekuperacji energii są coraz częściej stosowane we współczesnych samochodach osobowych wyposażonych w silnik spalinowy. Dzieje się tak, ponieważ taki układ pozwala na odzyskiwanieczęści energii bez konieczności montowania w pojeździe dodatkowych silników elektrycznych oraz baterii akumulatorów o dużej pojemności [2]. Powstaje jednak pytanie o granice stosowalności takiego rozwiązania. Ograniczeniami są w tym przypadku warunki ruchu samochodu oraz całkowita moc odbiorników energii elektrycznej w pojeździe. W zależności od tych czynników celowe jest wyposażenie samochodu w układ rekuperacji energii o większej lub mniejszej mocy. W artykule przedstawiono wyniki symulacji działaniaróżnych układów dla różnych warunków ruchu miejskiego. W tym celu zostały wykonane badania drogowe mające na celu reprezentowanie ruchu o różnej użyteczności pod względem możliwości odzyskiwania energii. Dla każdego rodzaju ruchu wykonano optymalizację parametrów układu. Na tej podstawie przedyskutowano zasadność stosowania układów o różnej mocy.

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.

Opis:
The growing requirements and needs of users as well as a strong emphasis on pro-ecological solutions cause an increasing interest in battery-powered electric mining machines. Internal combustion machines consume oxygen, generate noise, fumes and heat, which affects work in underground mines, and minimizing these factors is expensive. Battery solutions allow achieving the same operational parameters of machines with significantly higher safety, comfort and work culture. The problem, however, is their range or working time. The article presents global trends in the development of battery-operated machines for underground mining. Various machines in battery-powered versions have been presented. The applied solutions have been discussed, especially in the field of battery replacement or recharging and braking energy recovery. Manufacturers around the world offer more and more battery-powered machines. Some producers are announcing complete replacement of combustion solutions with electric ones within the next few years. There are also hydrogen machines on the horizon, which will probably be the next step on the road to a zero-emission industry.

Opis:
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.
W artykule przedstawiono wyniki badań odzysku energii hamowania osobowego samochodu o napędzie hybrydowym kół przednich. Badaniom poddano pojazd z szeregowo równoległym, spalinowo-elektrycznym, hybrydowym układem napędowym. Układ ten umożliwia zamianę rodzaju pracy silnika elektrycznego na pracę prądnicową i ładowanie baterii wysokonapięciowej z wykorzystaniem energii hamowania. Wykonano pomiary prądu ładowania baterii podczas hamowania przy różnych opóźnieniach ruchu pojazdu. Przeanalizowano algorytm sterowania prądem ładowania, udział energii odzyskanej w stosunku do całkowitej energii hamowania oraz moc hamowania odzyskowego w stosunku do całkowitego zapotrzebowania mocy hamowania. Przedstawiono chwilowe zapotrzebowanie mocy przy hamowaniu na jezdni poziomej o niewielkim współczynniku oporów toczenia. Przebadano udział mocy elektrycznej w bilansie energetycznym hamowania oraz zapotrzebowanie i odzysk energii podczas procesu hamowania.

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:
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:
Engine braking, just when the vehicle consumes no fuel, is an important component of the energy balance. In such states, the bus loses its cumulated kinetic and potential energies but alternators recover a portion of these energies into electricity. Simultaneously, electricity consumption in the diesel-engine city bus is a key component of the overall energy balance. A total energy output of receivers can be more than 4 kW. This paper presents the research results on performance of a serial bus driving varied urban routes. The recorded and investigated parameters include a total amount fuel and electricity consumed and an amount of electricity generated. Engine braking states were calculated with a created algorithm. On average, 17% of electricity was generated by bus engine braking. The research results and investigation refer to the entire year.
