Overview
Battery Needle Prick Squeeze Tester is a device used to test the safety and durability of a battery under a specific pressure. This testing machine combines two test methods of needle stick test and squeeze test. It is mainly used to evaluate the reaction of the battery under extreme physical stress. It can observe whether the battery will catch fire, explode or leak dangerous chemicals, so as to evaluate its safety in the event of severe physical damage. It is suitable for many types of batteries, especially lithium-ion batteries, because they are more prone to dangerous reactions in the event of physical damage.
Features
1. Combine the two test methods of acupuncture test and extrusion test; 2. Suitable for various types of batteries, especially lithium-ion batteries; 3. The rear side of the box is designed with a discharge trend and a pressure relief device; 4. The box is equipped with lighting; 5. The driving mode is hydraulic cylinder drive (extrusion) and hydraulic cylinder control (acupuncture); 6. The force value range is wide, the extrusion is 1~ 20kN, the acupuncture is 1~ 200Kg; 7. High force measurement accuracy, the extrusion is 0.1N, the acupuncture is +/- 1%; 8. Flexible unit conversion, support kg, N, lb; 9. The force value is displayed through the PLC touch screen; 10. The material of the box is durable, the inner box is stainless steel, and the outer box is Cold rolled steel plate sprayed.
Principle
The test should be carried out at an environment temperature of 20 ° C +/- 5 ° C. The battery is clamped flat on the fixture, and a non-corrosive stainless steel needle with a diameter of < 3~ < 8 mm is used to pierce the center of the largest surface of the battery at a speed of 10mm/s~ 40mm/s. Through hydraulic cylinder drive and control, the reaction of the battery under physical damage is simulated to evaluate its safety.
Applications
All kinds of battery acupuncture test simulation, when handling household waste, the battery is pierced by external conductors
Standards
GB/T2900.11-1988、GB18287-2013
Steps
1. Confirm the power supply voltage of the whole machine; 2. Open the safety box door and place the battery horizontally between the two battery clamps (about the central position is enough); 3. Turn on the power supply (the fan in the safety box starts), press the clear button to clear, press the "peak", and the corresponding "PEAK" indicator light is on; 4. Place the sample on the test bench of the battery needle punching test machine to make the fixture clamp the battery; 5. Set the needle punching time, after about 3S, the cylinder moves down and automatically performs the needle punching test. After reaching the preset time, the cylinder automatically rises and the steel needle returns; after about 3S, the fixture automatically releases and removes the battery to complete a test.
Notice
- The test sample should be a non-deformed sample or an intact sample of the shell Encasement, so as not to affect the test conclusion; - The operator needs to go through the training before the job, and please strictly abide by the test steps when operating; - Do not open the box door during the test to avoid accidents; - After the test is completed 5 minutes, remove the tested sample to avoid accidents; - Magnetic switch plays the role of adjusting the working stroke; - Keep the testing machine clean; - Do not disassemble and install electrical appliances with electricity, otherwise it is easy to damage the electronic components; - The testing machine shell should be reliably grounded; - Avoid intermittent operation during the test, otherwise it will affect the service life of the equipment; as much as possible, operate in place at one time to reduce the number of joints; - Before starting the machine, it should be carried out according to the specified lubrication parts and lubrication methods Lubrication; - Disassembly and assembly by professionals who understand the structure of the testing machine; - All valves on the testing machine should not be opened and placed to prevent dust from entering the interior and affecting the sensitive performance of the measurement mechanism; - When the testing machine is out of use for a long time, it should be coated on the working surface with anti-rust oil and stored in the drying place; - All parts of the equipment should be wiped frequently, and more attention should be paid to wiping during the rainy season. When not in use, use a dust cover to prevent dust from invading.
