This article provides a comparative analysis of various energy storage devices. A detailed review and analysis of molecular energy storage units is carried out, their main characteristics and parame-ters, as well as their application areas, are determined. The main types of molecular energy storage are determined: electric double layer capacitors, pseudo capacitors, hybrid capacitors. Comparison of the characteristics of various batteries is given. The parameters of various energy storage devices are presented. The analysis of molecular energy storage devices and accumulators is carried out. Ttheir advantages and disadvantages are revealed. It has been shown that molecular energy storage or double layer electrochemical capacitors are ideal energy storage systems due to their high specific energy, fast charging and long life compared to conventional capacitors. The article presents oscillograms of a lithium-ion battery with a voltage of 10.8 V at a pulsed load current of 2A of a laptop with and without a molecular energy storage device, as well as oscil-lograms of a laptop with DVD lithium-ion battery with a voltage of 10.8 V with a parallel shutdown of a molecular energy storage device with a capacity of 7 F and without it. The comparative analysis shows that when the molecular energy storage unit with a 7 F capacity is switched on and off, transient processes are significantly improved and there are no supply voltage dips. The dependenc-es of the operating time of a 3.6 V 600 mAh lithium-ion battery at a load of 2 A for powering mo-bile cellular devices with and without a molecular energy storage are given. It is shown that when the molecular energy storage device is switched on, the battery operation time increases by almost 20%.

BACKGROUND: Increasing energy efficiency of an electric vehicle is one of the most relevant issues at the current state of transport development. It is known that chemical current sources used in traction electric drive of vehicles have low specific power, low efficiency and high cost that makes the electric transport development difficult. AIMS: Making the choice of strategy of manufacturing of electric vehicle with batteries. METHODS: The mathematical models of various vehicle driving cycles, such as: the UNECE Regulation 83 urban cycle, NEDC, WLTC, JC08, EPA HWEET were used in the study that made possible to confirm adequacy of the developed structural model of the electric drive. RESULTS: The structural layout of the traction electric drive of an electric vehicle with combined energy source has been developed; the algorithm of its operation in the urban driving cycle has been defined. Electric transport efficiency was assessed during the study. The analysis showed that vehicles with solely chemical on-board energy sources do not have any prospects due to unsatisfactory technical properties and consumer attributes. Review of capacitors was performed in order to define the possibility of using them as energy source for next-generation vehicles. The study revealed sufficient advantages of capacitors in many respects. Analysis of vehicle motion in urban cycle was performed in order to develop the optimal design. The electric drive layout with a lithium-ion traction battery as the main energy source and a capacitor as the additional energy source was chosen. CONCLUSIONS: This solution makes it possible to develop the electric drive with optimal mass and dimensional parameters, to increase service life of energy storage and mileage without recharging of a vehicle. In addition, the combination of two electric energy accumulators and the developed algorithm of their operation makes it possible to achieve high efficiency of energy transferring.
