“…Then, the electric power balance efficiency is determined by the ratio: 3) results in progressive battery discharge (negative balance) [9][10][11][12][13]. During the automobile operation, the basic parameters are immediately changed to wide ranges; moreover, the electric power biases either in the positive or negative direction [14][15][16].…”

Increase in consumer power with the simultaneous reduction in the time and driving speed of personal automobiles results in systematic discharge of the batteries due to electric power balance inefficiency. The calculation methods for the evaluation of the electric power balance are inefficient, as a number of random factors (demand for electric power, driving speed, air temperature, technical condition of the units, etc.) influence the process of electric power generation, storage and consumption. The instrumental method for evaluation of the electric power balance efficiency assumes that the driver is informed about the battery charge condition prior to combustion engine startup, operational evaluation of the charge state change is performed during automobile driving and the driver is warned about critical reduction of charge state (including the forecast of its change for the period of the parking of the automobile in winter).

“…Power is transmitted to the front wheels through a continuously variable transmission E-CVT. Figure 3 presents a block diagram of the hybrid drive system used in the test vehicle [1,[5][6][7][8] During the research, the vehicle was attached to a mass of 150 kg. Registrations of the results were conducted by driving EV (Electric Vehicle).…”

Continuous energy intensity is a relationship between continuous energy intensity and energy intensity of movement. In the paper we proposed to analyze energy intensity of the movement, as the size specifying the power demand to the wheel drive and presented the balance of power of an electric car moving in the urban cycle. The object of the test was a hybrid vehicle with an internal combustion engine and electric motor. The measurements were carried out for 4 speeds and 2 driving profiles.

“…In addition to completely eliminating CO2 emissions at the place of use of an electric vehicle, the use of electric drive has one more important advantage over the drive from the combustion engine. It is the reversible operation of the electric machine, which gives the possibility of recovering energy into the battery, which during the braking would be dissipated to heat in the elements of the vehicle's braking system [4]. Unfortunately, there are also several major obstacles to the development of electric vehicles.…”

Research on the effects of the use of the range extender developed for a small commercial electric vehicle was presented in this paper. The range extender has a maximum output power of 2.65 kW. The developed auxiliary power unit consists of a three-phase generator propelled by an industrial low-power spark-ignition engine. The exhaust system was improved using a more efficient muffler. The implemented motorcycle muffler has a three-way catalyst (TWC) integrated inside. The use of the more advanced exhaust system aimed at reducing noise and exhaust emissions of the range extender. The efficient operation of the three-way catalytic converter requires a stoichiometric air-fuel ratio. To enable desired air-fuel ratio a fuel system was modified. In the first stage of research, the effects of improvements of the exhaust system on the range extender noise emissions were quantified. The next step covered the research of the fuel conversion efficiency, the exhaust gas composition, and the efficiency of conversion of the three-way catalyst. A significant decrease of noise and toxic gas emissions and an increase in the fuel conversion efficiency were revealed. The mentioned research was conducted in stationary conditions. After that, in the final part research of the running vehicle with the range extender on was made. The beneficial outcome of these tests enabled the development of a set of rules of the control of the range extender.
