Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] As we all know, a battery pack usually consists of a box, several battery modules arranged in the box, and a battery management module arranged in the box. Wherein, the battery management module is a BMS familiar to those skilled in the art, that is, a battery management system. Since this structure is familiar to those skilled in the art, this specification does not provide a schematic diagram of the battery pack, but this does not hinder the understanding of the present invention by the skilled person. Such as figure 1 As shown, the battery module 100 in the battery pack includes a battery module body 110 , a bottom plate 120 disposed at the bottom of the battery module body 110 , and a liquid leakage detection device 2 . Leak detection device 2, such as figure 2 As shown, it includes a strip-shaped body 22 and a connection portion 21 arranged at...

Abstract

The invention discloses a liquid leakage detection device and a battery module and a battery pack thereof. The liquid leakage detection device comprises a strip-shaped body and a wiring part arrangedat the end part of the strip-shaped body. Along the long-strip direction of the strip-shaped body, the strip-shaped body is internally provided with two wires which are parallel to each other and areburied in an insulator, and the two wires are connected with a wiring part. A plurality of wire windows are arranged on the upper surface of the strip-shaped body along the wire arrangement direction.The wire windows are opened on the insulator, so that the wires are exposed. A liquid leakage detection device is arranged on a bottom plate of the battery module in the battery pack. Capillary holesor capillary tubes are formed between the wire windows and the batteries above the wire windows, so that the wire windows can adsorb battery leakage in the battery module through a capillary effect,the battery leakage enables the two wires to be short-circuited, and whether the batteries have a leakage problem or not can be judged by detecting the resistance between the two wires.

Description

technical field [0001] The invention relates to battery liquid leakage detection and liquid cooling leakage detection in battery modules and battery packs. Background technique [0002] In an electric vehicle, the battery energy storage module provides electrical energy, and then the electric motor converts the electrical energy into kinetic energy for the vehicle to travel. Therefore, in the field of electric vehicles, the battery energy storage module is a key technology. In the prior art, the battery energy storage module of an electric vehicle is usually realized by a battery pack, and the battery pack contains several battery modules, and each battery module is provided with several batteries. In the prior art, the batteries in the battery module contain electrolyte. The vibration and collision during the driving of electric vehicles, as well as the age of the battery, may cause damage to the battery and electrolyte leakage. In addition, the battery pack is usually e...
