- Article presents the energetic balance of small-unmanned vehicle hybrid power transmission. The vehicle equipped with series hybrid transmission consisted of electric engines connected to the battery pack and small Diesel power generator. In mentioned construction, battery is used as energy buffer and combustion engine is used more as emergency power supply, and is turned on when battery is depleted. In other condition, power generator can be turned off, without reducing power of transmission parameters, except its range. Investigation was divided on two stages. At first stage generator, charging unit and battery were placed outside the vehicle. One piston power generator was feed by Diesel fuel. Fuel consumption of power generator was recorded from AVL fuel balance and energy parameters were recorded by power line analyser of BMR Company. Generator was connected to the direct current power plant. 70 Ah and 48 DC Lithium-polymer battery was charged from the power plant. After charging cycle, small water resistor was used to discharge the battery. Power parameters of discharged battery were measured. This enable to measure balance form tank to the battery. Second stage of the energetic balance determination was to measure internal resistances of vehicle power transmission from current inverter/converter connected to the engine and through the transmission up to the wheels of the vehicle. Power loss of energy at different speed of vehicle wheels without ground contact was measured in respect of power consumption. The series hybrid transmission is consider less efficient than parallel but because of specific configuration of power transmission, it was possible to reach higher efficiency
