In this paper we consider the questions of increasing the between-charge mileage (range) of electric vehicles and other vehicles with independent electrochemical power supplies. These are classified as hybrid vehicles, and can have various combinations of energy sources installed, such as: storage battery and electrical generator, driven by the engine, storage battery and solar panel, capacitor and electrical generator with engine, and others. The priorities for the development of the combined power supplies used now are considered and analyzed. On the basis of the power analysis of the combined power supply of the hybrid electro-mobile with a solar battery - of which the basic source of energy is the storage battery - the technique of defining the length of between-charge mileage of the vehicle is developed, depending on a combination of a set of parameters: both the components of the combined power supply, and the parameters of the electrical vehicle.

The operation of electric vehicles in urban conditions, especially in limited spaces, frequently imposes increased requirements on maneuverability. For electric vehicles operating on roads up to 30-40 km/hour, one of the most practical methods of increasing maneuverability is the use of completely independent drawing mono-blocks. These blocks are self-contained units each consisting of a draw wheel, electric motor, power supply, storage battery, and an electronic power converter. The blocks allow the vehicle to rotate 360 degrees around center axis, turn at any radius, and move in any direction, including straight to the left and to the right. The authors have developed and patented an increased maneuverability electro-cycle vehicle which consists of two mechanically connected block modules. In addition to increased maneuverability, such a design also increases reliability-failure of one block module does not prevent vehicle operation.
