FIELD: astronautics.
SUBSTANCE: invention relates to power supply of spacecraft with solar batteries (SB) and accumulator batteries (AB) mainly lithium batteries. Proposed method comprises charging, discharging and balancing of residual capacity of one or more AB units with thermal sensors and electric heaters. On the illuminated section of the orbit, AB is charged from SB to optimum values and residual capacity of the AB units and their temperature are leveled before entering the shadow. Orbital shad areas are kept with electric heaters by temperature of AB units in operating range.
EFFECT: increased time of active existence of spacecraft by increasing characteristics of electric power generation system, including service life of AB.
