METHOD FOR LIQUID THERMAL STABILISATION OF FLAT CELLS OF THE BATTERY MODULE OF A TRACTION ACCUMULATOR BATTERY Russian patent published in 2021 - IPC H01M10/60 

FIELD: batteries.

SUBSTANCE: invention relates to means of accumulating electric power for use in transport engineering as part of power supplying complexes of vehicles equipped with a traction electric drive. In the method for liquid thermal stabilisation of flat cells of the battery module of a traction accumulator battery, wherein heat from the battery cells is removed using metal plates and U-shaped channels with a liquid heat carrier, coupled with a distributor and collector of the battery module on the side of the pole terminals connected in parallel, accumulator cells, and forming accumulators of the battery module, the thermal stabilisation channels are made on the basis of U-shaped tubes installed in shaped blankings of the paired metal plates forming heat exchangers, assembled together with the accumulators into a package structure, installed on top whereof, depending on the number of accumulators in the module, are one or two interface printed circuit boards, tightened using large clamps when assembling the battery module and mechanically fixed by bolts to the walls and angles of the battery module.

EFFECT: structural simplification, possibility of using the accumulator battery both at high and low ambient temperatures.
