Embodiment Construction

[0020] refer to figure 1 , a thermal management monitoring device proposed by the present invention, comprising: water inlet pipe 1, water outlet pipe 2, first temperature sensor 3, second temperature sensor 4, first flow transmitter 5, second flow transmitter 6 , Pressure transmitter 7 and AD module 8.

[0021] The water inlet pipe 1 and the water outlet pipe 2 are connected in parallel between the vehicle refrigeration system B and the battery pack A, the water inlet pipe 1 is used to input the cooling water in the vehicle refrigeration system B into the battery pack A, and the water outlet pipe 2 is used to The cooling water lost in battery pack A returns to the vehicle refrigeration system B. The cooling water in the vehicle refrigeration system B enters the battery pack A through the water inlet pipe 1 to cool the battery pack A, and then flows back to the vehicle refrigeration system B through the water outlet pipe 2 to supplement the cooling capacity, thereby forming a...

Abstract

The invention discloses a thermal management monitoring device which is mounted at an inlet-outlet position of a water cooling pipe of a water cooling structure battery pack A or at one side, close toan evaporation pipe, of a direct cooling structure condensing pipe and a capillary pipe and used for providing the real-time accurate flow pressure difference, temperature and other base data for thermal management of the battery pack A so as to comprehensively calculate a working state of a battery pack A thermal management system; on the basis, the thermal balance circulation state of the thermal management system is judged, and an alarm function to failure is achieved. At the same time, the recorded data provide an effective reference for research and development type experiments. The efficient and convenient monitoring device is provided for thermal management of the battery pack A, the thermal management structure is simplified to a certain extent, and the security is strengthened.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a thermal management monitoring device. Background technique [0002] In the development of power batteries, safety issues have always been one of the important factors hindering the industrialization of lithium battery technology, and the performance of thermal management systems has always been an important basis for battery pack safety evaluation. [0003] At present, liquid level gauges are mainly used for monitoring water-cooling and thermal management systems for routine testing on the market. This method is slow and ineffective. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes a thermal management monitoring device. [0005] A thermal management monitoring device proposed by the present invention includes: a water inlet pipe, a water outlet pipe, a first temperature sensor,...
