摘要： The present invention provides a battery box having a heat directing function, a heat directing structure, and a method. The battery box comprises: a box body, the inner space of the box body being divided, by a heat partition plate, into a battery compartment in an upper portion and a heat concentration and distribution area in a lower portion; and at least one cell, the cell comprising an upper end face and a housing, the upper end face being provided with cell pressure relief valve, the cell being provided in the battery compartment, and the upper end face being provided to face the heat partition plate. The heat partition plate is provided with a heat directing area. An outlet of the cell pressure relief valve corresponds to the heat directing area. A heat flow discharged by the cell pressure relief valve enters the heat concentration and distribution area through the heat directing area. When thermal runaway occurs in the cell, the heat flow discharged by the pressure relief valve flows from the pressure relief valve to the heat directing area, then to the heat concentration and distribution area, and then to the outside of the box, and the bulk density of the heat flow is reduced step by step, thereby achieving the purpose of heat directing.

摘要： The present invention relates to a parallel electrical connection structure for battery poles, a parallel battery bank, a battery pack, and a manufacturing method thereof. The parallel electrical connection structure mainly comprises a common adjusting busway and a plurality of electrically connecting branches, the two ends of each of the electrically connecting branches are configured to be electrically connected to the poles of the same polarity of the plurality of individual batteries and the common adjusting busway, the poles of the same polarity of different individual batteries are connected in shunt via the common adjusting busway and the electrically connecting branches, and the current carrying capacity of each electrically connecting branch is smaller than that of the common adjusting busway. With the present invention, any battery with thermal runaway in a new energy battery pack can be discovered and isolated as early as possible, and the development of the thermal runaway in the battery can be blocked as soon as possible, to avoid negative effects of the battery with thermal runaway on other normal batteries in the battery pack and ensure the normal operation of the battery pack.
