Comparative assessment of the efficiency of some car drives

Abstract

The fundamental basis for the scientific progress is the cheaper technology. Systems analysis and engineering, decision-making systems are based on data completeness and their validation. The study aims to provide the following grounds for a systematic comparison of economic and environmental performance of vehicles with different fuel drives. The issue of logistical attractiveness and compatibility for Ukraine is especially relevant today. Thus, specific fuel consumption is calculated by determining the cost of electricity that goes to charge the traction battery from the mains and is equivalently converted into the cost of fuel. The paper presents a method of calculating the equivalent fuel consumption for electric vehicles according to European (l per 100 km) and American standards (miles per 1 gallon). According to the results of fuel efficiency studies, it is established that the equivalent fuel consumption on the territory of Ukraine of the studied electric vehicles is 8-10 times lower than the fuel consumption of cars of the same class with internal combustion engines.
