What testing tests are required for new energy vehicle batteries? In our lives, new energy vehicles have become a common means of travel, which greatly reduces air pollution for our environment, but the question is, how can the important components of new energy vehicles, namely batteries, be selected? A good car battery needs to be tested and tested layer by layer. The laboratory needs to test all the processes before knowing whether the battery is safe to install in the car. Battery safety is very important in new energy vehicles, and all must be strictly checked. The battery must be resistant to high temperature, extrusion, explosion-proof and short circuit. Let me explain to you which devices need to be used for battery detection to detect them? 1. Battery short-circuit test box: place the fully charged battery in an environment of 55°C±5°C, wait for the battery surface temperature to reach 55°C±5°C, leave it for 30 minutes, and then connect the positive and negative terminals of the battery with wires. And ensure that all external resistances are 80±20mΩ, monitor the temperature change of the battery surface during the test, when one of the following two situations occurs, the test is terminated: (1) The battery surface temperature drop is 20% lower than the peak value; (2) The short-circuit time reaches 24 hours; the battery should not catch fire or explode, and the maximum temperature should not exceed

simulated battery and battery pack are stored for 6 hours under the conditions of a pressure equal to or lower than 11.6kPa and an ambient temperature of (20±5) °C, and the battery is qualified if it does not explode or fire. 5.Battery extrusion test machine: The battery extrusion acupuncture test box is suitable for simulating the situation that various types of batteries are subjected to extrusion and acupuncture when using, transporting, storing or disposing of household waste. The test should be performed at 20℃±5 Under the ambient temperature of ℃, place the battery connected with the...

6. Battery weight impact tester: The test sample battery should be placed on a flat surface, and a rod with a diameter of 15.8±0.2mm (5/8 inch) is placed crisscrossing the center of the sample. A 9.1kg or 10kg weight is dropped onto the sample from a certain height (610mm or 1000mm). When the cylindrical or square battery is subjected to the impact test, its longitudinal axis shall be parallel to the plane and perpendicular to the longitudinal axis of the steel column. The longest axis of the square battery is perpendicular to the steel column, and the largest surface is perpendicular to...

7. Battery burning test machine: This machine is suitable for lithium battery (or battery pack) flame resistance test. Drill a circular hole with a diameter of 102mm on an experimental platform, place a wire mesh on the circular hole, place the battery under test on the wire mesh screen, install an octagonal aluminum wire mesh around the sample, and then ignite The burner heats the sample until the battery explodes or the battery burns out, and the combustion process is timed. 8. Battery thermal shock test machine: The battery thermal shock test box simulates that the battery is placed in a...
