One of the key steps to improve environmental situation is reducing pollutants released by automobiles. As of now, electric cars are the most commonly used type of eco-friendly vehicles. However, having a limited travel range they require an infrastructure system of charging stations to operate. Moreover, while electric vehicles don’t produce negative emissions directly they can still contribute to pollution if their energy is generated using fossil fuels. To further improve environmental benefits of electric cars charging stations on renewable energy sources should be developed.

For nickel-cadmium batteries of stationary application, a global empiric correlation C(i) describing the dependency of released capacitance by the batteries at different discharge currents was suggested, which is true for batteries of any capacitance and any mode of discharge (H, M, L). The global correlation C(i) can be described by generalized Peukert's equation, Korovin-Skundin's equation, probability integral, and porous electrode equation with accuracy sufficient for practical application. This correlation is most easily described by the generalized Peukert's equation C=Cm/(1+(i/IC/2)3.6).

In article experience of application of chemical sources of a current of electrochemical system lithium – tionilchloride and batteries on their basis, in onboard systems of electrosupply of modern and perspective space-rocket technics of Russia is presented.

The paper analyzes the energy balance of the solid oxide fuel cell (SOFC) battery. The existence of three temperature points satisfying the equation of SOFC battery energy balance is found out. The first point is trivial and corresponds to the cooled state of the battery. The second temperature point corresponds to an unstable state of the battery and finally, the third point is stable and corresponds to the normal operating state of the battery. The difference between the third and second point defines the temperature interval within the battery is able to self-heating. Analogy with the Semenov diagram for chemical reactors is noted.
