Opis:
For short distance (neighborhood) city transport of people, electric driven vehicle with advanced energy storage and electronic control system could assure fulfill essential requirements. range, acceleration ability and grade ability of electric driven small size city vehicle depend on: total vehicle mass, energy storage type and size, vehicle exploitation conditions (motorway, city traffic). Energy storage type and size optimization and full utilization of regenerative braking system leads to significant amount energy saving. Regenerative braking is particularly important in city traffic, where a lot of acceleration/braking cycles occur. Advanced secondary energy source consist of electrochemical battery and stack of supercapacitors. Using supercapacitors as an additional energy source makes it possible to improve battery life cycle and simultaneously to decrease the exploitation costs of electric vehicle. Short charging and discharging times of supercapacitors give ability to quick accept large amount of energy. In order to cooperate with batteries, a power electronic converter is necessary. Knowledge of vehicle energetic parameters could be obtained by model based simulation than verified by research testing. To estimating the energy consumption, energy recovery, range, acceleration and grade ability, simulation in MATLAB environment has been performed applying special low speed vehicle drive cycle based on ECE-15 driving cycle. The results of simulation are presented in this paper

Opis:
Global warming is a scientifically proven fact. Much of the temperature rise on the surface of the globe has been caused by human activity. That is why several years' efforts are aimed at reducing of CO2 emissions, related to the human activities. Major sources of CO2 emissions include electricity production from fossil fuels, transport sector and intensive agriculture. Cutting down forests also contributes climate changes. In the field of transport, decisions are made at the level of the European Commission, and also by the wider audiences of introducing limits for CO2 emissions entire fleet of new passenger cars for year 2015, 2021 and later. The actions taken by car manufacturers are diverse. Cheaper and simpler solutions are focused on the concept of micro-hybrid based on a system of 48 V. More advanced solutions are a wide range of hybrid vehicles, including PHEV, and pure electric vehicles. The use of lighter materials, improved aerodynamics and rolling resistance, more efficient internal combustion engines and gearboxes also have an impact on energy demand and, consequently, CO2 emissions. An important problem to solve in many countries is the dissemination of renewable energy sources rather than fossil fuels. This article presents an outline of the issues related to eco-friendly solutions, including requirements for batteries intended for this type of vehicles. It also presents an overview of European standards in this area and progress in advanced energy sources.

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:
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.
