Problems solved by technology

[0002] A battery module usually includes multiple batteries, and multiple batteries can be connected in series or in parallel through structures such as bus bars to output electric energy; in order to effectively monitor the temperature of the battery, a temperature acquisition unit can be set in the battery module , usually the temperature acquisition unit transmits the heat of the battery through structures such as bus bars, and indirectly collects the temperature of the battery. During this process, the heat of the battery will be affected by structures such as bus bars. Therefore, the temperature collected by the temperature acquisition unit cannot accurately reflect the temperature

Abstract

The embodiment of the invention provides a battery module, relates to the technical field of batteries, and aims to solve the technical problem of inaccurate battery temperature detection. The batterymodule provided by the invention comprises a battery and a temperature acquisition unit. The temperature acquisition unit comprises a support plate and a thermosensitive element; the thermosensitiveelement is arranged on the upper plate face of the supporting plate; the lower plate face of the support plate is attached to the battery. The temperature of the battery can be directly transmitted tothe thermosensitive element through the support plate, so that a heat transmission link between the battery and the thermosensitive element is effectively reduced, and the thermosensitive element canreflect the temperature of the battery more accurately.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module. Background technique [0002] A battery module usually includes multiple batteries, and multiple batteries can be connected in series or in parallel through a structure such as a bus bar to output electric energy to the outside; in order to effectively monitor the temperature of the battery, a temperature acquisition unit can be set in the battery module , usually the temperature acquisition unit transmits the heat of the battery through structures such as bus bars, and indirectly collects the temperature of the battery. During this process, the heat of the battery will be affected by structures such as bus bars. Therefore, the temperature collected by the temperature acquisition unit cannot accurately reflect the temperature. Contents of the invention [0003] The invention provides a battery module capable of accurately collecting the temperature of the b...
