Abstract

The invention discloses a battery protection circuit. The battery protection circuit comprises a battery module, a pressure detection module and a battery protection module, wherein the pressure detection module can detect pressure and generate an electric signal according to the pressure; and the battery protection module is electrically connected with the battery module and the pressure detection module, and can control the short circuit of the battery module according to the electric signal. The battery protection circuit provided by the embodiment of the invention can be arranged inside or outside the battery module, so that the applicability of the battery protection circuit is improved, and the safety of the battery module when the battery protection circuit is impacted by external pressure is ensured.

Description

technical field [0001] The invention relates to the field of battery protection, in particular to a battery protection circuit. Background technique [0002] At present, lithium-ion batteries are widely used in the field of new energy vehicles. However, when an external force such as a collision of a new energy vehicle occurs, the lithium-ion battery is prone to fire and combustion. [0003] In the related art, two kinds of separators with different fracture energies are used to protect the battery. Using the above method can improve the safety of the laminated battery when it is squeezed, but for the wound battery, the above method is difficult to apply to the wound battery because the battery separator and the pole piece are in a continuous state. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a battery protection circuit, which can be ar...
