technical field

The utility model relates to the technical field of batteries, in particular to a water ingress detection module applied in a shared two-wheeler battery.

Background technique

The shared two-wheeler battery is mainly used in outdoor scenarios due to its complicated operating conditions. In rainy days or when it is used improperly, water is very easy to enter the inside of the battery. After the battery pack enters water, the performance of the battery will be reduced and the use of the battery will be shortened. Life; when the water intake is large, it is likely to cause a short circuit inside the battery pack, resulting in a thermal runaway event of the battery pack.

At present, the common water intrusion detection device has a complex structure, many components, and a large volume. Some of them also require an external power supply to supply power. For shared two-wheeler batteries or shared battery replacement batteries, the volume of the battery pack itself is relatively small. , so it is difficult to have extra space to install a large water inflow detection device, a device with a complex structure and many devices, which is accompanied by a higher price. For shared two-wheeler batteries, this is a relatively big disadvantage.

Obviously, the described embodiments are Some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Referring to FIG. 1, a water ingress detection module applied in a shared two-wheeler battery includes: a connector 1, a wire 2, a PCB board 3, a back glue 4, a resistance wire 5, and a solder joint 6; the resistance wire 5 is connected by The connector 1 is connected to the protection board (not shown in the figure) in the battery pack, the two ends of the resistance wire 5 are fixedly connected with solder joints 6, the solder joints 6 are respectively connected with the connector 1 through the wire 2, and the solder joint 6 is welded and fixed to one end of the wire 2. The other end of the wire 2 is fixedly connected to the connector 1, and the connector 1 is connected to the protection board by plugging. The wire 5 is fixedly connected to the top of the PCB board 3, the bottom end of the PCB board 3 is bonded with a back glue 4, and the end of the back glue 4 away from the PCB board 3 is bonded with a sticker. When in use, the PCB board 3 can be fixed by removing the sticker. In the position in the battery pack where water is easy to enter, the PCB board 3 is a circuit board with strong hardness, which is not easy to bend or break; the resistance wire 5 is set in a disc shape and is regularly arranged, which can improve the detection surface of the resistance wire 5 and improve the In order to improve the detection accuracy, when there is water on the surface, its impedance value will change. If the impedance value suddenly drops to a very low level, it means that the water has completely covered the detection module. It should be noted that the detection module in this embodiment can be used for Shared two-wheeled vehicles can also be used for water ingress detection of shared battery swaps, but not limited to this.

How to use: Integrate the resistance wire 5 on the surface of the PCB board 3.

The protection board is used to detect the impedance value of the resistance wire 5, and the entire detection module passes through The adhesive 4 is fixed in the area where the battery pack is prone to water ingress. When there is water in the water ingress detection module, its impedance value will change immediately. The protection board reports the corresponding water ingress level according to the detected real-time impedance of the module. The maintenance personnel take corresponding measures according to the different levels of water ingress reported, and choose to take out the battery for drying treatment or directly disassemble the battery pack for maintenance. The battery is damaged due to long-term water ingress or even a thermal runaway event caused by a short circuit caused by water ingress.
