[Original by Dongchedi Industry] Recently, Ora Lightning Cat equipped with honeycomb energy short knife battery jointly launched a series of battery safety tests.
Honey Cell Energy Short Knife Battery Safety Test
The Lightning Cat launched this time is equipped with a L600 lithium iron phosphate short Knife battery cell with a honeycomb energy capacity of 184 amphibious. The test includes four major tests: 20mm steel needle needle puncture, a whole pack of 140 seconds fire, a whole pack of thermal runaway and a whole pack of 6 meters high altitude drop. In addition, Ora Lightning Cat also participated in the TOP Safety domestic first electric vehicle high-speed spiral tumbling and drop challenge.
, whether the needle puncture experiment can be passed is one of the standards for testing battery safety performance.
During the honeycomb energy short knife battery cell needle puncture experiment, China Automobile Research used 20mm steel bars far beyond the national standard (8mm steel needle) to directly puncture into the short knife battery cell, mainly simulating that after the accident, foreign objects such as guardrails and steel bars pierce the battery. The results showed that when the 20mm steel bars were stabbed, the appearance of the honeycomb energy short knife battery remained intact and no fire or explosion occurred.

In addition, the battery spontaneous combustion caused by poor thermal stability is an important risk facing new energy vehicles at present. Therefore, the honeycomb energy short knife battery uses twice the national standard 140-second high-temperature roasting and fire to continuously heat the outside of the battery pack, and there were no fires or explosions in the end.

At the same time, whether the power battery can effectively perform thermal barriers and whether the battery pack can quickly relieve pressure are important criteria for testing battery safety.
According to the official introduction of Honeycomb Energy, in this thermal runaway experiment, the short knife battery can effectively thermally block when the battery cell is thermally out of control to avoid heat transfer to other battery cells. From the beginning of thermal runaway to the end of stationary, no fire or explosion accidents occurred.
Oula Lightning Cat Battery Safety Test
In addition,Oula Lightning Cat also conducted drop test to simulate accidents such as chassis dragging, falling and bumping in real life.
In this experiment, the battery pack fell freely at a height of 6 meters, far exceeding the international drop standard of 1 meter. The results show that the appearance of the honeycomb energy short knife battery pack is intact, and there is no displacement or electrolyte leakage in the internal battery cell.
Ola Lightning Cat Battery Safety Test
It is worth noting that Ola Lightning Cat also participated in the TOP Safety domestic first electric vehicle high-speed spiral tumbling and drop challenge.
China's first high-speed spiral rolling test for electric vehicles
test site, Lightning Cat rushed onto the spiral single-sided bridge at a speed of 60 kilometers per hour, rolled 540 degrees and fell into the rammed earth hardening pit. When the vehicle rushed out of the spiral one-sided bridge to fell into the pit, the maximum drop was more than 6 meters. In the end, the battery pack looked complete and there was no fire or explosion.
