Technical and economic analysis of the use of mobile charging stations for electric vehicles in the Republic of Tajikistan

Abstract

The global electric vehicle market is increasing. The main motivation for switching to this innovative type of vehicle is, first of all, reducing the impact on the environment, reducing operating costs, the possibility of using new technologies in transport, etc. Of course, the development of electric vehicles, like other industries, has its problems. The paper examines the methodology for determining the optimal options for charging infrastructure for electric vehicles, as the main factor influencing the widespread use of electric cars. The purpose of the study is to determine the optimal option for mobile charging stations (MCS) for the conditions of Tajikistan based on a comparative analysis of key indicators: cost, weight and resource. To conduct a study to determine the optimal option for mobile charging stations, a comparative analysis method was used. For the conditions of Tajikistan, to determine the optimal option for mobile charging stations (MCS), a corresponding comparative analysis was carried out in terms of such indicators as cost, weight, and resource. It was revealed that the MCS based on autonomous generators with an internal combustion engine (ICE) is superior to other options in all respects. However, we should not forget that the greatest harm is caused to the environment by such an MCS, and it requires a constant supply of fuel. The best option is to combine lithium-ion batteries with an autonomous generator and a solar battery or wind power plant. Considering that the multi-station system is often located in one place, at the first stage it was proposed to create a multi-station station with an autonomous generator, lead-acid batteries, or a hybrid version. In the future, it is necessary to gradually switch to the joint use of hybrid installations based on lithium-ion batteries in combination with an internal combustion engine, solar panels, or a wind-electric installation. The practical significance of the study is to create a stable and cost-effective infrastructure for charging electric vehicles, including based on alternative energy sources, in Tajikistan, which contributes to increased mobility, economic development and environmental sustainability of the region. The development of electric vehicle infrastructure will stimulate the growth of the electric vehicle market, which in turn will contribute to the development of related economic sectors. Similar installations can be used in other industries, such as tourism, power supply to remote villages, and geological exploration.
