Abstract

The invention relates to resistance wire cloth, device and method for battery pack bottom collision monitoring, the resistance wire cloth comprises a first resistance wire layer and a second resistance wire layer which are stacked, and an intermediate insulating layer is arranged between the first resistance wire layer and the second resistance wire layer; the first resistance wire layer comprises a first cloth body and further comprises a plurality of first resistance wires arranged in the plane of the first cloth body at intervals in the first direction; the second resistance wire layer comprises a second cloth body and a plurality of second resistance wires which are arranged in the plane of the second cloth body at intervals along a second direction; and the first direction is intersected with the second direction. According to the invention, the high-risk position of a battery pack can be monitored in real time, the fault occurrence position can be accurately judged and a user can be timely reminded to maintain a vehicle when the battery pack has faults such as bottom collision and cracking, and when the battery pack has a slight fault, the system does not give an alarm and false alarm of the battery pack fault is prevented.

Description

technical field [0001] The invention relates to the technical field of battery pack fault monitoring, in particular to a resistance wire cloth, a device and a method for monitoring the bottom of a battery pack. Background technique [0002] With the rapid development of new energy vehicles, the battery pack technology as a core component is rapidly iterative, and the weight is gradually improved. However, at the same time, the risk of cracking the bottom of the battery pack is increased. The bottom of the battery pack may crack when encountering ground bumps. However, at present, there is no technical method to monitor the location and severity of the bottoming of the battery. Water ingress may occur during subsequent vehicle use, which may lead to risks such as short circuits, fires, and explosions. [0003] The prior art can only carry out passive protection, using a protective plate to resist external intrusion. Or use an acceleration sensor at the front of the car to...
