Description

A high-efficiency battery detection device

technical field

The invention relates to the technical field of lead-acid battery sealing detection, in particular to a high-efficiency battery detection device.

Background technique

With the upgrading of battery manufacturing technology, lead-acid batteries are currently developed into lead-acid maintenance-free batteries and colloidal maintenance-free batteries. There is no need to add electrolyte or distilled water in the use of lead-acid batteries, mainly using the positive electrode to generate oxygen, which can be absorbed at the negative electrode to achieve oxygen circulation. , to prevent moisture loss. Lead-acid water batteries are mostly used in tractors, tricycles, car starters, etc., while maintenance-free lead-acid batteries are widely used, including uninterruptible power supplies, electric vehicle power, and electric bicycle batteries. When lead-acid batteries are used in electric vehicles, the vehicles will vibrate and bump during actual use. At this time, it cannot be confirmed whether the sealing performance of lead-acid batteries is guaranteed. In addition, sealed lead-acid batteries are also sensitive to the ambient temperature, and if the temperature is too high, the service life of the battery will be affected.

The advantages and disadvantages of the sealing performance of lead-acid batteries are very important to the impact on the performance of lead-acid batteries and the safety of customers using lead-acid batteries. The first is the impact on the performance of the lead-acid battery itself. The lead-acid lead-acid battery has poor sealing performance, and oxygen in the air will enter the lead-acid battery, causing an oxidation reaction of the negative electrode, resulting in the electrical energy stored in the lead-acid battery being oxidized by the negative electrode. Release is not working properly. The second is the impact on the safety performance of lead-acid batteries. The sealing performance of lead-acid batteries is poor, and the sulfuric acid inside the lead-acid battery will permeate. When connected, the voltage and current will leak out along the permeating sulfuric acid, causing the arc to ignite the lead-acid battery casing and equipment, and also causing the danger of electric shock to personnel.

At present, most of the air-tightness detection devices of electric bicycle batteries use manual methods. The ear-washing ball is used to test each cell of the battery. The efficiency is low, and workers often fail to detect or miss the inspection. When the leak point is very small, it will not be detected, and the test result will be unreliable; the air tightness test of each cell with a sphygmomanometer is inefficient and labor-intensive. It can be done carefully. As the battery capacity increases, the force of manually squeezing the sphygmomanometer ball is small, and the test is inaccurate or missed. There is also a mechanical device for testing, and a fixed vacuum pumping device can only measure one cell at a time. However, a battery needs to be tested 6 times and can only be fixed in one position, which is low in efficiency and inconvenient to operate. Moreover, the battery cells of lead-acid batteries on the market must be leaked during the production process to prevent electrolyte leakage. In the technology, the airbag is used for detection. Align the air nozzle of the airbag with the liquid injection port of the battery, and hold the airbag firmly. If it can be squeezed, it means that the battery unit is not well sealed. If it cannot be squeezed, it means that the battery cell is well sealed. The detection method has high labor intensity and low detection accuracy, so we propose a high-efficiency battery detection device to solve the above problems.
