Abstract

The present application relates to a battery and a power consuming device. The battery includes: a battery cell; a temperature sensor for measuring the temperature of the battery cell; a sensor mounting assembly for mounting the temperature sensor; and a signal transmission component for being electrically connected to the temperature sensor to transmit a temperature signal of the battery cell, the signal transmission component being detachably connected to the sensor mounting assembly. The replaceability and compatibility of the temperature sensor can be improved to facilitate the maintenance of the battery and the replacement of a failure apparatus, and reduce the cost of the battery and the scrapping probability of the entire battery.

Claims (26)
