FIELD: temperature control for storage batteries of motor vehicles. SUBSTANCE: shell has internal and external walls with space between them communicating with external casing accommodating reversible non-evaporating hydrogen having equilibrium hydrogen pressure lower than 100 mbars at 500 C and hydrogen concentration within gas absorber being 0.1% by mass. Inner space between walls accommodates non-evaporating gas absorber with equilibrium hydrogen pressure higher than 100 mbars at 500 C and hydrogen concentration of 0.1% by mass at same temperature. In case of too high temperature of battery cells, heat transfer is effected due to high heat transfer of hydrogen at fast increase in its pressure in hollow space of shell. When conditions causing inadmissible temperature increase are eliminated, heat dissipation is minimized by recovering low hydrogen pressure in hollow space of shell due to reabsorbing hydrogen by means of reversing gas absorber as it cools down. Examples of working pressures and types of gas absorbers are given in description of invention. EFFECT: improved reliability of storage battery due to augmented heat transfer. 24 cl, 14 dwg
