Abstract Electric vehicle manufacturers pay particular attention to climatic conditions in the Russian Federation, seeing that chemical reaction rates usually decrease when the environment temperature drops. The analysis of ambient temperature data in the region where electric vehicles will most likely be used aims to select extreme temperatures for calculating powers of a thermostat control system for traction batteries. An electric vehicle simulation model to calculate the power of the thermostat control system for traction batteries is described. An empirical model to assess a state of health of traction batteries is selected. This simulation model adequately reflects thermal processes in a traction battery and can be used for further research.

The authors provide a copious literate review on powertrain design optimization for electric vehicle (EV) powertrains. The review shows a gap in the state of science regarding the consideration of all customer relevant requirements. Existing approaches either focus on performance and energy consumption or concentrate on vehicle dynamics. Based on this insight, the authors analyze customer requirements and derive all vehicle properties that are influenced by the powertrain concept. They find that costs, longitudinal performance, lateral dynamics, off-road capabilities and energy consumption are key vehicle properties. The powertrain concept affects all these properties and thus determines the satisfaction of customer requirements. Subsequently the authors describe a vehicle simulation model that represents all predefined customer requirements in dependence on the powertrain concept design.

The Future

Intelligent integration of decentralised energy resources, local storage and direct consumption are key factors in achieving the transformation of the energy system. In this study, we present a modular simulation concept that allows the planning of decentralised energy systems for buildings and building blocks. In comparison to related studies, we use a simulation model for energy planning with a high time-resolution from the perspective of the energy system planner. In this study, we address the challenges of the grid connection in combination with an increasing number of electric vehicles (EV) in the future. The here developed model is applied for an innovative building block in Germany with a photovoltaic (PV) system, a combined heat and power (CHP) unit, battery storage and electric vehicles. The results of the simulation are validated with real-life data to illustrate the practical relevance and show that our simulation model is able to support the planning of decentralised energy systems. We demonstrate that without anticipating future electric vehicle charging, the system configurations could be sub-optimal if complete self-sufficiency is the objective: in our case study, the rate of self-sufficiency of the net-zero energy building will be lowered from 100% to 91% if considering electric vehicles. Furthermore, our simulation shows that a peak minimising operation strategy with a battery can prevent grid overloads caused by EV charging in the future. Simulating different battery operation strategies can further help to implement the most useful strategy, without interruption of the current operation.

Motor of electric vehicle is able to be used to brake regeneratively, so braking energy can be recycled. Braking stability of electric vehicles with electro-hydraulic hybrid braking system can be influenced by braking force distribution between hydraulic braking force and regenerative braking force. In order to research on braking stability and braking energy recovery, simulation platform of electro-hydraulic hybrid brake system based on Carsim and Matlab/Simulink is built, and a control strategy of electro-hydraulic hybrid brake were proposed. The vehicle simulation models with electro-hydraulic hybrid brake system and with conventional hydraulic braking system were applied the brake on different adhesion coefficient separately. The simulation results show when electric vehicle is in the conditions of low braking intensity, all vehicle braking force is provided by regenerative braking force, and braking energy can be not only recycled, but brake performance requirement can also be satisfied; when electric vehicle is in the conditions of moderate braking intensity, regenerative braking and hydraulic braking are coordinated with each other, electro-hydraulic hybrid brake can not only satisfy the same and better brake performance, but also braking energy can be recycled and demand of hydraulic pressure can be reduced.

Vehicle Charging

The development of electric vehicles, which is also observed in the Russian Federation at present, leads to the need to create a charging infrastructure. Variable operating conditions, and in particular low ambient temperature, cause difficulties in the use of electric vehicles, which are associated with a low power reserve and increased energy consumption in the winter. These features of the electric vehicle operation in the Russian Federation can lead to an increase in the number of charging stations needed to create a developed infrastructure, and, therefore, can increase capital costs. The purpose of this research is to identify patterns of the electric vehicle charging station operation in the regional infrastructure using the example of Tyumen city to develop a methodology for calculating their quantity that can satisfy demand in variable climatic conditions with a low capital cost. As a result of this study, patterns of change in the number of charging sessions, its duration and the amount of energy transferred to electric vehicles from the ambient temperature were obtained.
