[0057] For a second example, see Figure 6 to Figure 11

[0058] The battery temperature monitoring and early warning system and the power supply device 300 provided by the second embodiment of the present invention have the same realization principle and technical effect as the first embodiment. For a brief description, the second embodiment does not mention, you can refer to the first Corresponding content in an embodiment.

[0059] Image 6 It is a three-dimensional structure diagram of the liquid-cooled flat tube 100 in the battery temperature monitoring and early warning system provided by the second embodiment. Figure 7 yes Image 6 The three-dimensional cross-sectional view of the liquid-cooled flat tube 100 shown. Such as Image 6 with Figure 7 As shown, in this embodiment, the liquid-cooled flat tube 100 is further provided with a second wiring groove 150 on the other side of the cooling liquid circulation channel 130 opposite to the first wiring groove 140 . ...

no. 3 example

[0064] For a third embodiment, see Figure 12 to Figure 13

[0065] The battery temperature monitoring and early warning system provided in this embodiment is different from the above embodiments in that the liquid-cooled flat tube 100 is not provided with the wiring trough, but is provided with a plurality of installation parts 180 instead. Each of the installation parts 180 is used to install one of the temperature detection units 210 , specifically, the temperature sensor is disposed inside the installation part 180 , and the data transmission line is routed inside the battery module 310 .

[0066] There are many ways to set up the installation part 180. Optionally, such as Figure 12 As shown, a plurality of installation parts 180 are arranged at intervals on one side of the cooling liquid circulation channel 130, or as shown in FIG. Figure 13 As shown, a plurality of installation parts 180 are arranged at intervals on both sides of the cooling liquid circulation channe...

Abstract

The invention provides a battery temperature monitoring early warning system and a power supply device. The battery temperature monitoring early warning system comprises a liquid cooling flat tube, at least one temperature detection unit and an early warning unit, wherein the liquid cooling flat tube is arranged inside a battery module; at least one section of the liquid cooling flat tube is positioned between any two adjacent layers of sub-modules; the temperature detection unit is used for detecting the temperature of the liquid cooling flat tube and used for transmitting detected temperature to the early warning unit; the early warning unit is used for transmitting an early warning signal in case of thermal instability of the battery module. By adopting the battery temperature monitoring early warning system and the power supply device of the design, the early warning unit is used for transmitting an early warning signal in case of thermal instability of the battery module, the temperature inside the battery module can be effectively detected, when thermal instability happens, drivers and passengers can be reminded in time, and areas of thermal instability can be accurately locked through assistance.

Description

technical field [0001] The invention relates to the technical field of battery safety, in particular to a battery temperature monitoring and early warning system and a power supply device. Background technique [0002] The temperature monitoring technology of the existing battery module can only detect the temperature of the peripheral single battery, but in the actual power supply process of the battery module, the heat dissipation performance of the peripheral battery is often better than that of the internal battery, so the detected peripheral battery There is a large gap between the temperature of the body battery and the actual temperature inside the battery module, especially when the temperature inside the battery module has exceeded the battery's tolerance range, but the detected temperature of the peripheral battery is still in a normal state, the monitoring system will According to the measured results, it will be determined that the temperature state of the batter...
