FIELD: electrical engineering. SUBSTANCE: running control over voltage and temperature of storage battery is so conducted by selection of unspecified value of current ( from low to high ) during charge of various storage batteries that charge of storage battery stops either in point in which rate of temperature rise of battery increases as compared with previous rate of rise that exceeds specified standard value or in point in which difference in change of voltage of storage battery continuously drops number of times preset in advance. EFFECT: expanded functional capabilities and enhanced accuracy and speed of charge. 19 cl, 22 dwg
