Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery measurement, in particular to a battery thickness measuring device. Background Art
[0002] During the charging and discharging process, the battery volume often expands. Monitoring the expansion size of the battery has important guiding significance for the battery pack.
[0003] The device described in patent [CN 212205953 U] is to place the battery upright and then collect thickness changes at different positions on the large surface of the battery through a matrix sensor; although the described device can monitor the expansion at different positions on the large surface of the battery, there are still "blind spots" for measurement, such as the edge position of the battery and the position of the battery's tabs. The data at these key positions are difficult to detect due to the design of the device; the thickness sensor design of the device is also too dense, resulting in the inability to fully utilize the collected data and reducing work efficiency;
[0004] At the same time, due to the size of the device, when measuring batteries of different sizes, the device needs to be redesigned, which is not advantageous in terms of time or economic cost.
[0005] The thickness detection point of the present invention can be moved, and the position of the battery cell can also be moved, so that the thickness change at any position of the battery cell can be measured; only two thickness sensors are needed, which can not only reduce the cost but also greatly improve the data utilization efficiency;
[0006] At the same time, because the thickness detection point and the position of the battery cell can be adjusted, this patent can be applied to batteries of different sizes, and one machine can be used for multiple purposes. For this reason, we propose a battery thickness measuring device. Utility Model Content
