FIELD: electrical engineering.
SUBSTANCE: every storage battery or storage battery unit has its heating element connected to terminals of storage battery in unit thereof via contacts of thermal relay with its winding connected to terminals of storage battery or unit thereof and, thyristor with its control transition connected to terminals of pulsed transformer winding. Said transformer embraces storage battery jumper of the side of positive electrode of every storage battery or conductor connected to positive electrode of storage battery unit. Note here that power of heating element automatically cut-in with temperature inside storage batteries or unit thereof makes 8-10% of that of storage batteries in their unit.
EFFECT: high level of capacity in charging and discharging in operation under various conditions.
