Abstract

The invention belongs to the technical field of battery thermal management, and discloses a device and a method for measuring the dosage of a cooling liquid for inhibiting battery thermal diffusion. The device comprises a sealing box, a battery, a heating device, a high-level container, a cooling device and a recovery device, the battery is placed in an inner cavity of the sealing box; the heating device is configured to heat the battery; cooling liquid is contained in the high-position container; the cooling device comprises a heat exchanger and a control valve; the heat exchanger is arranged on the periphery of the battery and communicated with the high-level container; the control valve is arranged between the heat exchanger and the high-level container, and can obtain the heat diffusion state of the battery and control the flow of cooling liquid entering the heat exchanger from the high-level container; and the recovery device is configured to be capable of collecting the residual cooling liquid in the battery. The device for measuring the dosage of the cooling liquid for inhibiting the thermal diffusion of the battery can simulate the thermal diffusion state of the battery and accurately measure the dosage of the cooling liquid required for inhibiting the thermal diffusion of the battery.

Description

technical field [0001] The invention relates to the technical field of battery thermal management, in particular to a cooling liquid dose measurement device for inhibiting battery thermal diffusion. Background technique [0002] Battery thermal diffusion, also known as battery thermal runaway, refers to the phenomenon that the temperature of a single cell of the battery rises due to the exothermic chain reaction, and at the same time, the temperature of the remaining cells is uncontrollable one after another. Depending on the main raw materials of lithium-ion batteries, there will be different starting temperatures and different energy release rates when thermal runaway occurs. For example, compared with lithium iron phosphate cathode materials, ternary cathode materials have a relatively large energy release rate under the same capacity. Of course, this must also take into account various factors such as the design of the mechanical structure of the cell. [0003] In order...
