Recently, Euler Lightning Cat, equipped with short blade batteries, joined forces with China Automotive Research Institute to conduct a series of battery safety tests. The experiment mainly simulates the safety issues that may be encountered in daily life scenarios, and ultimately the short knife battery passes various tests with excellent performance, elevating battery safety to a new level.

The Lightning Cat launched this time is equipped with L600 lithium iron phosphate short blade battery cells with a honeycomb energy capacity of 184Ah. The tests include four rigorous tests: 20mm steel needle puncture, 140 second fire on the entire package, thermal runaway of the entire package, and 6-meter high-altitude drop. The test difficulty is more stringent than the national standard requirements. In the end, the short blade battery passed the safety test with full marks, providing users with multiple safety guarantees. In addition, Euler Lightning Cat also participated in TOP Safety's first domestic high-speed spiral rolling and falling challenge for electric vehicles. This challenge starts with simulating actual traffic accidents and tests the safety of the battery from multiple angles. In the end, this highly impactful vehicle test showcased the high safety quality of the short blade battery to the fullest extent.

The ability to pass needle puncture experiments has always been the hardcore standard for testing battery safety performance. The difference between the needle piercing experiment of the short knife battery cell this time and previous needle piercing experiments is that, according to the national standard, an 8mm steel needle was used in the needle piercing experiment. This time, China Automotive Research Institute used 20mm steel bars that far exceeded the national standard to directly pierce the short knife battery cell, mainly simulating foreign objects such as guardrails and steel bars piercing the battery after an accident. The results showed that when the 20mm steel bar was punctured, the appearance of the short knife battery remained intact and no fire or explosion occurred.

The self ignition of power batteries due to poor thermal stability is an important risk faced by new energy vehicles and a matter of great concern to users. In this fire experiment, the short knife battery was subjected to double the national standard 140s high temperature roasting and continuous heating of the battery pack by fire. The short knife battery completed the challenge with full marks without any accidents such as fire or explosion, providing consumers with sufficient escape time.

When a power battery experiences thermal runaway, the ability to effectively block heat and quickly release pressure from the battery pack is an important criterion for testing battery safety. In this thermal runaway experiment, the short blade battery was able to effectively block heat during the thermal runaway of the battery cells, avoiding heat transfer to other cells. From the beginning of thermal runaway to the end of static operation, no fire or explosion accidents occurred.

The drop test mainly simulates real-life accidents such as chassis dragging, falling and collision. In this experiment, in order to verify the safety of the battery to the greatest extent possible, the battery pack was dropped from a height of 6 meters in a free fall manner, which is more extreme than the national standard of 1 meter drop. The appearance of the final battery pack is intact and undamaged, with no displacement of internal cells or leakage of electrolyte.
