Lotus Motor Company released a video of its electric vehicle battery harsh test on the 30th to overcome the phenomenon of electric vehicle catharsis (temporary demand stagnation) at home and abroad and relieve consumer anxiety.

Lotus cited “fire anxiety” as the reason consumers hesitate to purchase electric vehicles. Lotus captured the development process of electric vehicles that had not been revealed to the outside world. Lotus introduced what tests the batteries of its electric vehicle lineup, Eletra and Emeya, will be mounted on the car and emphasized through the video that it is prepared for fire and impact situations.

Lotus researchers conducted a harsh durability test that directly applied high heat of 1,000°C to the outside of the battery pack. As a result of carefully wrapping the outside of the battery with aviation-grade insulation, it was able to withstand hot heat without internal damage. In addition, heat diffusion was prevented through specially designed air ducts and floor cooling plates, and the risk of accidents was reduced by operating a water pump when battery heat increased.

It also devised safety measures to prevent battery damage from external shocks. Lotus has enhanced its protection capabilities by installing battery packs with high-strength beam structures in Eletra and Emeya. To demonstrate this, Lotus conducted a test that impacted the front, side, and floor of an electric vehicle battery pack like a new car crash test.

In the video, you can also see a durability test in which the battery is artificially immersed in seawater for 24 hours. It also goes through more than 50 difficult tests, including voltage, resistance, insulation, and confidentiality.

Lotus Motor Korea official said, “Lotus continuously checks the detailed condition of the car during driving or charging through a cloud-based intelligent monitoring system, so Lotus customers can operate electric cars with more confidence,” adding, “Next-generation Lotus electric vehicles such as Elletra and Emeya have conducted harsh battery durability tests beyond what can be experienced in real road conditions.”
