Description

Technical field [0001] The invention relates to a temperature measurement control device and method for a novel battery and an assembled battery, and belongs to the field of battery safety protection. Background technique [0002] With the continuous application of power batteries and assembled batteries in daily work and life, the application environment is constantly changing, and batteries and assembled batteries need a safer temperature control system. [0003] With the continuous development of new energy, the number of batteries and assembled batteries continues to increase, and the working temperature detection points also continue to increase. Conventional temperature measurement methods are no longer suitable, such as thermistors, thermocouples and other temperature sensing front ends. Each battery is A temperature sensing front end is needed. 300 batteries require 300 temperature sensing front ends, and 600 wires are required to connect to the temperature sensing front en...

AI Technical Summary

Problems solved by technology

[0008] (d) Since they use metal conductive materials, metal wires are susceptible to corrosion, causing measurement failures;

[0009] (e) Due to too many wires, it is not conducive to the heat dissipation of the measured object body;

[0010] (f) Since they are made of plastic materials (polyolefin, nylon, polyurethane, rubber) on the outside, they cannot be detected when they encounter electrolyte corrosion, which may easily cause a short circuit between them and the battery and cause a fire;

[0011] (g) Because they are easy to be broken down under high voltage conditions, they will cause damage to the detection line and cause safety accidents
