AI Technical Summary

Problems solved by technology

For example, in a car, sensors can often be powered by, for example, a battery, and if the sensor keeps drawing power while the car is parked, it can cause the battery to die, rendering the car unable to start
On the other hand, although powering off the sensor can reduce its power consumption, it may cause the sensor to fail to monitor changes in external parameters correctly.

Abstract

The invention relates to a sensor for monitoring the state of a battery pack. The sensor is characterized in that the sensor comprises a sensing element for detecting the state of the battery pack toobtain detection data and thereby obtain a curve of the detection data with respect to time, a sampling module which is used for limiting a sampling period and sampling the detection data in the sampling period based on the curve, and a judgment module which is configured to output a warning signal when the sampled detection data are greater than a preset threshold value and / or the change rate ofthe sampled detection data is greater than a preset change rate threshold value, and the warning signal indicates that a thermal runaway condition may occur in the battery pack. The invention furtherrelates to a battery module comprising the sensor, a battery management module, an electric vehicle, and a monitoring method for monitoring the state of the battery pack by using the sensor.

Description

technical field [0001] The present disclosure generally relates to a sensor and a monitoring method for monitoring using the sensor. The present disclosure also relates to a battery module and a battery management assembly having the sensor. The present disclosure also relates to an electric vehicle having the sensor. Background technique [0002] Sensors are widely used in parameter monitoring. On the one hand, in some occasions, people hope that the sensor consumes as little power as possible to avoid running out of the power supply of the sensor. For example, in a car, sensors can often be powered by, for example, a battery, and if the sensor were to draw power while the car was parked, it could cause the battery to die, rendering the car unable to start. On the other hand, although powering off the sensor can reduce its power consumption, it may cause the sensor to fail to monitor changes in external parameters correctly. [0003] In automobiles, the battery pack use...
