Many factors affect the range of an electric vehicle: speed, driving style and ambient temperature can reduce the range of a full charge. Cold weather poses two main problems for electric vehicles: cold air limits battery performance, and the robo-heater significantly drains the battery. Studies have shown that 21.5 degrees is the optimal temperature for the operation of an electric car battery. Because an average of 21.5 degrees Celsius is the most optimal temperature when it comes to the range of an electric car. This actually prolongs its operation. At 21.5 degrees, the electric car's temperature system does not work, so energy is used for its movement. At -20°C, an electric car loses an average of 50% of its battery charge range. At -10 – 40%, at 0 – 20%. When the temperature is +10o C, the real driving distance of the electric car corresponds to 100% charging of the battery. At +21 o C, the real distance can be increased to 15%. When it is +40oC, the performance of the battery drops significantly to 80%, and the rate of charge rapidly decreases as the temperature increases. The energy consumption of electric vehicles is largely influenced by weather factors. Studies have shown the influence of ambient temperature and wind speed on energy consumption. The results show that at low speeds (30 km/h) the relative influence of ambient temperature is extremely high. The lowest energy consumption is achieved at a temperature of 20° C. At higher speeds (130 km/h), the relative influence of the temperature of the external environment is much lower. It has been proven that 21.5 degrees is the optimal ambient temperature for the operation of an electric car battery during operation, a decrease or increase in temperature leads to a decrease in the efficiency of electric car operation.

Abstract Charge imbalances in high-voltage batteries, including battery cell arrays, such as lithium-ion in hybrid vehicles, tend to develop and increase over time as the batteries are charged and discharged, or even when the battery remains charged but not in use. This reduces the efficiency of the battery charging and discharging modes, and limits battery life and capacity. The article describes a method and device for performing the charge equalization operation when charging a storage battery. The elements of the charger circuit have been selected, the parameters of which are sufficient for charging with equalizing the charge of the Audi Q5 hybrid Quattro car. Calculations of the pulse mode of charging the battery of the specified car, as well as the time spent on charging with equalizing the battery charges are given. The charging time of the considered battery with the elimination of a 15% imbalance of the batteries will last up to 139 minutes (2.31 hours). The results of calculating the operating parameters of the device indicate that the device for equalizing the charge of the batteries is operable, can be implemented on a modern element base at a relatively low cost, and is capable of charging the battery in a time acceptable for the operation of the car.

Future car parks will require significant power to support electric vehicle (EV) charging as there will be both an increase in the penetration of EVs and a higher demand for charging power as battery packs increase in capacity. The effective management of the charging and local battery storage can be installed to help prevent excessive increases in electrical feeder capacity; however, it is inevitable that car parks will attain significant power capability in the future. There is therefore an opportunity for car park owners to utilise this and generate additional revenue by providing frequency response services to the electrical grid. This paper describes the modelling of a car park that utilises photovoltaic power generation, battery storage, and EV charging management strategies to provide a grid frequency response service. The analysis using simulated car park data shows that it can provide a high availability in terms of service but it is dependent on the capacity of the installed generation and storage.

Successful commercialization of electric vehicles will require a confluence of technology, market, economic, and political factors that transform EVs into an attractive choice for consumers. The characteristics of the traction battery will play a critical role in this transformation. The relationship between battery characteristics such as power, capacity and efficiency, and EV customer satisfaction are discussed based on real world experience. A general problem, however, is that electrical energy can hardly be stored. In general, the storage of electrical energy requires its conversion into another form of energy. Electrical energy is typically obtained through conversion of chemical energy stored in devices such as batteries. In batteries the energy of chemical compounds acts as storage medium, and during discharge, a chemical process occurs that generates energy which can be drawn from the battery in form of an electric current at a certain voltage. A computer simulation is developed to examine overall battery design with the MATLAB/Simulink. Battery modelling with this program have error level less than 5%.

One of the directions for making cleaner and more economic vehicles is to adopt electric vehicle concept. Therefore, an internal combustion powered engine Nissan Micra Vehicle was converted into battery powered electric vehicle. The power train of the car was redesigned to use DC electric motor in replacement of the existing internal combustion engine and to give the gear ratios possibility of a normal car. The power rating of the motor was determined by considering the rolling, gradient and aerodynamic resistances which gave a total tractive effort of 12190.84 N. The designed power rating was then determined to be 8 kW and this value was used to select the number of batteries that gave the required current to reach an adequate range of operation. To balance the weight of the car, the battery rack was located behind the center of gravity to give the developed vehicle a neutral steer characteristic. After installation of electric motor, inverter and the batteries, then the batteries were connected in series and parallel to the inverter with cable wire via variable frequency drive to ac motor and potentiometer. The vehicle was then evaluated and the voltage produced was able to move the vehicle at 6.24 m/s and the maximum frequency obtained was fifty megahertz (50 MHz).

Abstract: The basic idea behind a solar electric car is to utilise the power that is stored in a battery both during and after a solar panel charge. Due to the fact that they don't release any greenhouse gases or other pollutants while in operation, solar automobiles are made with environmental protection in mind. Solar-powered cars have the ability to rapidly minimize the demand on fossil fuels, which would slow their depletion and reduce the negative effects of climate change. In this project, we'll investigate how a charge controller can be used to control the flow of electricity produced by a solar panel array into a battery pack. The stored energy will subsequently be used to power a PMS motor, which will drive the car. The direction and speed of the car's movements will be under our control via a motor controller. Additionally, we'll talk about the procedure for assembling the car's mechanical components. Finally, we'll demonstrate how to attach the electrical system to the car's mechanical frame.

The motivation for this work is to find a better and efficient energy storage solution for electric vehicle. It is done by comparing the performance of three different batteries, which are: Lead Acid battery, Li-ion battery and Graphene battery. In this paper, an electric vehicle model is created in Simulink using MATLAB software. The constructed model is based on the existing electric car TATA Nexon EV. Also, unlike the real car the model presented has a different battery pack and the battery parameters such as SOC, current, voltage, distance, velocity, and weight are changed to carry out the comparison between different battery technologies. The model will be simulated to obtain data regarding vehicle performance, energy consumption and range on the new FTP75 test cycle. The obtained know-how will help on later improvements of the electric model regarding methods to improve the vehicle performance and the simulation helps to choose the right powertrain for the vehicle without carrying out any real-life experiments.

The Car AC Control Using IoT Sensor. The interior temperature of the car rapidly increases mostly during the hot summer months. This paper aims to address the challenge of maintaining a comfortable interior temperature in car, especially during hot summer months. To overcome this problem a mobile application is developed which helps to monitor the temperature in the car by using the Internet of Things (IoT). With this application the AC can be switched ON before getting into the car as the AC controller is linked to the mobile application. To power the system, a lithium-ion battery is used, which is recharged by the conversion of kinetic energy generated by the vehicle's movement, particularly from the wingtips. The intelligent design of air conditioners will ensures the efficient energy consumption with which the battery life can be prolonged. The proposed method will monitor the temperature inside the car.

The aim of the work is to choose a method of a solar car battery cooling. The student engineering team of Peter the Great Petersburg Polytechnic University designs the car. The analysis of the electrical circuit of the battery is carried out, the heat release is estimated due to three factors. According to the conditions of reliable operation of the battery, it is necessary to maintain its temperature range below 45°C, which requires cooling. The paper analyzes the possibilities of liquid, air-cooling, compares the free and forced methods of convective heat transfer. For the normal operating mode of the electric vehicle, environmental temperature at the level up to 38°C, a criterion thermal engineering calculation of the forced air-cooling of the corridor assembly of 405 battery cells providing the required heat dissipation is performed. It is shown that relatively high values of the heat transfer coefficient are provided under turbulent flow conditions characterized by Reynolds criteria above 103. On the basis of an analysis of the steady-state stationary heat-removal regime, it was concluded that an air flow provides a temperature gradient, sufficient for cooling the lithium-ion battery of a Solar Car «Polytech Solar».

This study examines the design of heat exchanger made of copper tube for cooling electric vehicle car battery system and the effects of base fluid and nanofluid (as coolants) channeling inside the heat exchanger to increase heat transfer between the compartment of the electric vehicle car and the heat exchanger and comparison between them. The nanofluid (CuO/pure water) was prepared by dispersing a nanoparticle (CuO) in base fluid (pure water). nanofluid (CuO/pure water) with a nominal diameter of 50 nm at volume concentrations (0.27 Vol. %) at batteries’ compartment temperature was used for these investigations. The analysis showed that secondary cooling system by means of nanofluid (CuO/pure water) has advantages in improving the thermal conductivity and heat transfer coefficient, better from base fluid (pure water) also in Nusselt number. This results work on reducing the electric power loss in the form of thermal energy from batteries. This led to increase in the efficiency of the electric vehicle car battery, hence also improved the performance of the EV car and battery lifetime.

Abstract: Electric cars are initially developed as an alternative option for existing gas powered car. It also shows good results in both performance and energy utilization. Usage of electric cars are encouraged due to its effect over global warming as there is no emission of harmful gases like CO, CO2, NOX. The electric car is an automobile that is propelled by one or more electric motors, using energy stored in rechargeable batteries. This idea was coined in later 18th century. But it was initiated in 20th century to roll on roads. Even though we use battery as the energy source, we need a cooling system. It isnecessary to ensure the proper dissipation of heat which is emitted from the battery while transmission. Here we discuss about the cooling system of battery in an electric car. We use three different liquids to analyze its effectiveness. Those fluids are Glycol, Fluorinert FC72 and NOVEC7200 (Ethoxy nonaflurobutane). We have designed and drawn the model using CATIA V5 software and analyzed using ANSYS FLUENT software. Then analyzed best Coolant for the battery coolingsystem.

Contour Positioning System (CPS) is a new system invented for electric vehicles to calculate the remaining battery capacity for reaching a desired destination. Instead of using conventional electric car estimation in terms of distance, a CPS system can figure out extra energy needed when an electric car is traveling on different contour lines. Extra current will be drawn for generating torque required by the electric car on an inclined plane, for instance traveling uphill. By using coordinate conversion, sets of longitude and latitude readings can be converted into distance difference along the pathway and the elevation levels difference are calculated; the extra force and torque needed along an inclined plane can be further counted which will then lead to the extra current drawn from the electric car's battery pack. Data collections and real-time validations have been done to clarify the calculation results. By performing a series of battery capacity calculation, CPS can give a higher precision and accuracy of remaining battery life to reach the desired location

The Korean government is facing growing concern over the increasing levels of fine dust. A significant contribution to this problem comes from coastal vessels. To mitigate this, an electric ship propulsion system has been proposed as a solution to reduce air pollution. The application of a fully electric propulsion system in a ship is challenging due to size, capacity limitations, and the cost investment of the battery system. To address the challenges of battery limitation and initial investment costs, the development and supply of removable battery supply systems (RBSSs) for fully electrified battery powered (F-EBP) car ferries are studied. A permanent magnet synchronous motor (PMSM) for the F-EBP car ferry using a roll-on/roll-off-type RBSS is developed in this work. Firstly, the concept of the F-EBP car ferry is discussed, and the specifications of the electric car ferry propulsion system are provided. Secondly, motor design and electromagnetic analysis are performed using finite-element analysis (FEA), where the heat sources including copper loss, core loss, and PM loss are calculated. Mechanical loss is also considered. Finally, a thermal network of the motor is built considering the lumped-parameter model. The results of the thermal analysis indicate that the motor operates within the safe region and can perform well in rated working conditions.

The importance of electric car purchase incentives is starting to be questioned. The objective of this paper is to explore the potential effect of reducing or removing electric car purchase public subsidies in the European Union. To this end, the system dynamics Powertrain Technology Transition Market Agent Model is used. The size and timing of purchase incentives for this technology in European countries are investigated under eight scenarios and sensitivity analysis performed. The simulations suggest that, in the short-run, the electric car market share is higher when the subsidies remain in place. In the medium-run, a purchase subsidy scheme granting €3000 for plug-in hybrid electric cars and €4000 for battery electric cars over the period 2020–2024 yields the fastest electric car market uptake of all the scenarios considered. We conclude that, though the current evolution of the battery price is favorable, electric car purchase subsidies remain an effective policy measure to support electro-mobility in the next years.

Abstract: Road side emergencies such as tyre punch, is a problem commonly observed in cars. Conventional car jacks uses mechanical advantage to allow a human to lift a vehicle by manual force. This paper is a modification of the current toggle jack by incorporating a servomotor whose motion as well as torque is transmitted via gear trains to the power screw, in order to make load lifting easier for emergency use with the aid of a 12V car battery as power source. Gear ratio is used to increase the lifting power. The significance and purpose of this work is to modify the existing car jack in order to make the operation easier, safer and more reliable in order to save individual internal energy and reduce health risks especially back ache problems associated with doing work in a bent or squatting position for a long period of time. Fabrication work has been done using milling, drilling, grinding, and welding machines. The developed car jack is tested on 1400kg Toyota Camry car. Loads were increased at intervals of 50 Kg using bags of cement and it was observed that, deformation of threads began at loads beyond 1550 Kg. this implies that, the electric powered jack mechanism is capable of liftingvehicles with maximum load of 1550 Kg.

The efficient management of battery state of charge (SOC) is crucial for maximizing the performance, range, and longevity of electric vehicle (EV) batteries. This paper presents a novel approach for estimating the optimal state of charge of electric car batteries using an Extended Kalman Filter (EKF). The EKF is a recursive algorithm that combines measurements from various sensors with a dynamic battery model to estimate the current SOC and predict future SOC values with high accuracy. The paper provides a detailed explanation of the EKF algorithm and its application to battery SOC estimation, highlighting its ability to handle nonlinearities, uncertainties, and measurement noise inherent in battery systems. Furthermore, this research presents a simulation-based validation of the proposed EKF approach using real-world driving data from electric vehicles. The simulation results demonstrate the effectiveness of the EKF algorithm in accurately estimating the SOC of electric car batteries under various operating conditions, including different driving patterns, temperatures, and battery degradation scenarios.

Abstract This article deals with determining statistically significant factors affecting the sale of battery electric vehicles in different European countries. Typical representative countries were selected on the basis of cluster analysis. The input data for multiple regression models and vector autoregressive models include data for the last decade and thus essentially cover the complete history of the electric car market. Attention is paid not only to the European leader but also to countries with a lower share of electric cars. The results of this study show the existence of a common factor in the countries with different development trends in the battery electric vehicle market. However, differences among individual countries are generally so significant that the identified factors vary from country to country.

The aim of this work was to perform tests of genotoxicity and toxicity on samples of riverine sediments from a location subject to motor industry load (car battery production). Together with sediment samples we also collected benthos, biofilm and juvenile fish. Concentration of lead was established in all the samples since the sewage waters discharged from the car battery production plant are heavily polluted with lead. Genotoxicity was tested with two tests of genotoxicity: the SOS chromotest and the Escherichia coli WP2 test. The toxicity of sediments was tested with a test of toxicity performed on a water crustacean Daphnia magna. A profound toxic influence upon benthic organisms was found; a consequence of the river pollution with waste water and flush water from the car battery production plant. This toxic effect was also proven by an aqueous leach from the test performed with Daphnia magna. Both tests of genotoxicity proved a significant genotoxic potential of the sediment samples linked with the growth of the concentration of lead in the sediments (up to 647 mg kg-1). The content of lead also increased in the biofilm (up to 3.37 mg kg-1 of dry mass) as well as in the fish bodies (up to 804.5 mg kg-1 of dry mass). This thesis is the first study of the load imposed on this river as a consequence of the waste water and flush water discharge from the motor industry production plant (car battery production).

This paper presents the reasons for the increased level of automobile accumulators are given, the design of the start-charging device of increased reliability is considered. The most damaged nodes of the system of electrical equipment of motor vehicles are listed, the differentiation of elements from the standpoint of their structural reliability is shown, ways of increasing the reliability of the elements of the electrical equipment system are determined. It is shown that the main reasons for finding optimal modes of operation of vehicles electrical equipment are the economic factor, the impact on the environment, the need to reduce the dependence on the constant rise in price of petroleum products. Car lead acid batteries are starter batteries, that is, they do not involve deep discharge. As a result of the deep discharge of the battery on its plates, the phenomenon of sulfitation and shedding of the active mass. The longer the battery is discharged, the more active it becomes and the starter current decreases. Therefore, the issue of regular recharging of the battery and guaranteed starting of the internal combustion engine with a discharged battery is urgent. It is established that the causes of rapid discharge of the battery or reduction of its capacity may be the deviation of the electrolyte density from the recommended value, the sulfation of the plates and the shedding of their active mass, malfunction of the vehicle electrical equipment. Most serial chargers are not designed for starting a car engine, and specially designed models have a high price. The complexity and considerable volume of work on researching and predicting the reliability of the car electrical system requires the efforts of specialists, as well as the coordination and coordination of their activities by developing methodological recommendations first to address partial and then general issues of the problem. It is shown that quantitative indicators of the reliability of each element included in the system are of great importance when addressing issues related to the organization of maintenance, the establishment of overhaul terms and repair volumes of the car electrical system. The developed charger will reduce the time spent on starting the car engine during the cold period, as well as significantly increase the battery life due to its full charge.
