Abstract
Abstract An emergency power system is designed to provide additional battery power for starting engines operating on petroleum products, when the normal battery supply for this purpose has insufficient energy available. The system utilizes either primary reserve cells or dry charged secondary cells for the supplemental power and connects them in such a manner that they can be activated immediately when required.
