DEVICE FOR PROTECTION OF LITHIUM-ION BATTERY Russian patent published in 2015 - IPC H01H37/00 

FIELD: electricity.

SUBSTANCE: invention relates to switching or locking bypass devices installed in parallel with each lithium-ion battery of space vehicle. Device comprising casing, fixed and movable contacts, electric heating and thermal elements, additionally has elastic and resilient membrane. The movable contact is made out of low-melting alloy and is arranged together with the electric heating element in the cavity limited by the casing, elastic membrane and one fixed contact. The cavity between the casing and elastic and resilient membranes is by one third filled with liquid with low specific heat of evaporation, acting as thermal element. In fixed contacts holes are made.

EFFECT: increased reliability of response, assurance minimum transient resistance of contacts and continuity of circuit during the battery operation as part of power supply system of the space vehicle during the entire service life.
