Abstract

The invention relates to the technology of batteries, in particular to a battery cell temperature monitoring device and a battery pack comprising the same. The battery cell temperature monitoring device provided by the invention comprises a substrate, a plurality of temperature sensors and a gating apparatus, wherein the substrate is suitably fixed together with a battery cell, the plurality of temperature sensors are arranged in positions corresponding to a temperature sampling region of the battery cell on the substrate; and the gating apparatus arranged on the substrate is connected with the plurality of temperature sensors and is configured to output a measuring signal of at least one of the plurality of temperature sensors selectively.

Description

technical field [0001] The invention relates to battery technology, in particular to a battery cell temperature monitoring device and a battery pack containing the device. Background technique [0002] A lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between positive and negative electrodes to operate. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. [0003] Lithium-ion batteries have certain temperature requirements. The factory provides the charging temperature range, discharge temperature range, and storage temperature range. Overvoltage charging will cause permanent damage to the lithium-ion battery. Espe...
