Abstract

The invention provides a temperature monitoring apparatus. The temperature monitoring apparatus comprises a liquid-cooling flat tube and at least one temperature detection unit, wherein the corresponding temperature detection unit is in contact with the liquid-cooling flat tube for monitoring the temperature in a battery module; a power supply apparatus adopting the temperature monitoring apparatus comprises the battery module; the battery module adopts multiple single batteries; the multiple single batteries are divided into multiple layers of sub modules; each sub module layer comprises multiple single batteries; the liquid-cooling flat tube is arranged in the battery module; and at least one section of the liquid-cooling flat tube is positioned in the gaps between any two adjacent sub module layers. By adoption of the designed temperature monitoring apparatus and the power supply apparatus, the temperature of the batteries on the periphery of the battery module can be monitored while the internal temperature of the battery module can be effectively monitored as well; and when a condition of thermal instability occurs, the internal abnormal temperature of the battery module can be monitored in time and the region of thermal instability can be positioned accurately.

Description

technical field [0001] The present invention relates to the technical field of battery thermal management, in particular to a temperature monitoring device and a power supply device. Background technique [0002] At present, the temperature sensing device of the battery module can only detect the temperature of the peripheral single battery in the battery module. During the power supply process of the battery module, because the heat dissipation performance of the peripheral battery is better than that of the internal battery, the temperature sensing device There is a large gap between the measured temperature of the peripheral single battery and the actual temperature inside the battery module, especially when the temperature inside the battery module has exceeded the battery’s tolerance range, and the temperature of the peripheral battery measured by the temperature sensing device When the temperature is still in a normal state, the monitoring system will judge that the te...
