Nowadays, manufacturing of electric vehicles remains one of the most dynamically developing industries all over the globe. The issues of battery efficiency improvement by a suitable battery cell structure selection and battery control system enhancement are of the highest priority in the process of the battery design. Battery management systems (BMS) with modular structure have become the most popular as control systems in electric vehicle battery applications. The paper describes design principles of such type of BMS and necessary hardware.

One of the challenges that currently face manufacturers of electric vehicles is the development of an effective energy source. Currently, the main independent source of energy of electric vehicle is an electric traction battery of chemical type, but due to its low intensity, it cannot provide long mileage without recharging. The article describes a method of improving vehicles ' energy efficiency through energy recovery oscillations of the suspension system when driving on uneven road surface. To convert the mechanical energy of vibrations into electrical, the leading manufacturers of the world are developing special regenerative shock absorbers. The article describes the design of such absorbers designed by companies Audi and ZF. For quantitative evaluation of vibrational energy that is potentially possible to convert to electric we used a simulation mathematical model of motion of two-axle vehicle on ridges, implemented in the simulation package MATLAB/Simulink. As inputs in the model was used the implementation of random road profiles that were obtained by the method of forming a filter by known from the literature the spectral characteristics of the irregularities for different types of roads. As a result of the mathematical model of computational experiments, it was determined the amount of dissipation in the suspension system energy when the vehicle is moving with different speed on different road types. Also for comparison was determined the energy spent by the vehicle at different speeds on the road with asphalt. The comparison of the obtained energy values allows to make a conclusion about prospects of application of energy recovery oscillations of the suspension system especially for vehicles capable of high speeds on dirt roads.

The development of a modern vehicle is associated with the need to co-operate with a variety of components from different manufacturers, due to the fact that companies mainly specialize in the manufacture of specific equipment (powertrain, steering, braking system, dashboard, etc.). Majority of manufacturers of automotive electronic units do not allow changes to their finished products, therefore, when integrating components into a single vehicle, there is a problem with the coordination of control signals and communication protocols. In response to this problem, it is required to use an additional electronic unit - the electronic control unit of the upper layer (ECU). This device generates signals for each component in accordance with the requirements of manufacturers. This unit may have different components and different functionality depending on the requirements. The unit is based on a microcontroller with a control program. To control the power discrete output, power transistor MOSFET keys are used. Optocouplers or specialized microchips are used for processing discrete digital signals. Moreover, the unit is equipped with specialized microcircuits, which allow the exchange of information with other electronic units via digital protocols.

Рассматриваются вопросы моделирования радиоэлектронной обстановки с использованием среды имитационного моделирования AnyLogic. Для создания модели используется агентный подход. Имитационная модель содержит агенты трех классов: объект, радиоэлектронное средство, радиосеть. Моделируются перемещение объектов воинского формирования в соответствии с видом боевых действий и темпами движения, а также постановка радиопомех, приводящая к переходу радиосетей на запасные частоты. Реализация имитационной модели позволяет сформировать календарно-событийное представление радиоэлектронной обстановки, которое может быть использовано в качестве исходных данных для оценки ситуативной обстановки, в том числе с учетом применения радиоэлектронных средств субъектами данной ситуативной обстановки. The issues of modeling the radio-electronic environment using the AnyLogic simulation environment are considered. An agent approach is used to create the model. The simulation model contains agents of three classes: an object, an electronic device, and a radio network. The movement of objects of military units is modeled in accordance with the type of hostilities and the speed of troops movement, as well as the setting of radio interference, leading to the transition of radio networks to spare frequencies. The implementation of the simulation model allows creating a calendar-event representation of the radio-electronic environment, which can be used as source data for assessing the situational environment, including taking into account the use of electronic means by the subjects of this situational environment.
