POWER FEEDING SYSTEM Russian patent published in 2018 - IPC B60R16/33 B60L11/14 B60L11/18 H02J7/14 

FIELD: electrical engineering.

SUBSTANCE: power feeding system comprises power generator (2), lead-acid battery (15), lithium-ion battery (16), two paths (C1, C2) connecting lead-acid battery (15) and lithium-ion battery (16). System further comprises a MOS (50) and relay (51) of the path. Relay (51) of path of lead-acid battery (15) is located in path C2, which comes from lithium-ion battery (16) into lead-acid battery (15). MOS (50) is located in path C1, which comes from lithium-ion battery (16) into lead-acid battery (15). Further, the system comprises an engine restart module (9, 16, 52, 60), electric load (30), control module (60). Electrical load (30) is connected to the side of lead-acid battery (15). Control module (60) switches the MOS (50) and relay (51) of the path to a conductive state while the engine is running, with the exception of the period during the start-up phase of the automatic restart and during idling engine shutoff, whereby a glow from lithium-ion battery (16) to electrical load (30) is performed using both paths (C1, C2).

EFFECT: attenuation of deterioration in the characteristics of the lead-acid battery is achieved.
