Problems solved by technology

The temperature of each battery in the battery pack detected by this method can only be an approximate value, and the actual value of each battery cannot be detected
There is a certain blind area in the detection of the temperature difference of each battery in the battery pack and the formation of local hot spots.
It is not conducive to the solution of problems such as battery life reduction or thermal runaway

Abstract

The invention discloses a distributed type battery temperature dynamic detection system. The distributed type battery temperature dynamic detection system comprises a temperature detection and controlmodule, a temperature detection channel switching matrix module and a battery temperature probe module, wherein the battery temperature probe module comprises a temperature probe group and a batterypack; the temperature probe group comprises a plurality of temperature probes; the battery pack comprises a plurality of batteries; each temperature probe corresponds to only one battery; the temperature detection and control module is connected with the temperature detection channel switching matrix module; the temperature detection channel switching matrix module is connected with the temperature probe group; the temperature probe group is connected with the battery pack. A distributed type battery temperature dynamic detection method is adopted and the temperature difference of each batteryin the battery pack can be reduced at maximum; the formation of a local heat region is inhibited; a condition that the whole service life of the battery pack is reduced or the thermal runway, causedby the fact that the battery at a high-temperature position is rapidly attenuated, is prevented.

Description

technical field [0001] The invention relates to a battery management system, in particular to a distributed battery temperature dynamic detection system. Background technique [0002] In order to ensure the safety of the lithium battery pack and maximize the performance of the lithium battery pack, a battery management system (BMS) must be equipped with the lithium battery pack. The battery thermal management system (Battery Thermal Management System, BTMS), the subsystem of the BMS, is a key factor in determining the performance, safety, life and cost of the battery pack. As far as battery thermal management is concerned, battery temperature detection is equivalent to the "eyes" of the battery thermal management system and is one of the cores of the entire system; the entire system relies on the "eyes" of temperature detection to control the actuators of the entire system. [0003] In addition, the biggest core key problem of the battery thermal management system is: how t...
