ELECTRIC POWER SYSTEM FOR PERSPECTIVE NON-NUCLEAR SUBMARINES Russian patent published in 2014 - IPC B63G8/00 B63H23/00 

FIELD: electricity.

SUBSTANCE: electric power system comprises an accumulator battery, two diesel generating sets, two electrochemical generators, an automatic circuit breaker, electric propulsion system, control boards with switching and protective gear and switchboards. The electric propulsion system is made as all-mode electric propulsion system consisting of a propulsion motor and its power supply system, bypass power diodes are also installed in it and the system is connected to the power line by these diodes. The accumulator battery consists of two groups; each group is coupled to the power mains through automatic circuit breakers at the accumulator battery boards. The accumulator battery is made as a lithium-ion rechargeable cell; each group is divided into subgroups and connected to the power mains through double automatic circuit breakers. The distribution boards are connected to semi-groups of the lithium ion battery through diode isolation.

EFFECT: increased sea endurance of a submarine.
