When it comes to electric vehicles, battery safety concerns every consumer. To minimize failure rates, manufacturers must invest effort. Today, we analyze the MG Cyberster’s battery pack. We explore how it achieves “zero natural failure and zero thermal runaway” in 300,000 units. We uncover the hidden secrets behind this achievement.
MG Cyberster features a battery pack called the Magic Cube Battery. This battery uses a horizontal arrangement instead of a vertical one. This design reduces the thickness of the battery pack to just 110mm. This measurement leads the industry.
This layout ensures smooth electrolyte flow in the battery pack. It maintains pressure and lithium-ion activity. The pressure adaptive management system further extends the lifespan of the entire cell.
The battery pack will use cells from CATL. The individual cell failure rate reaches the PPB level. This means that in every billion cells, only one may pose a safety risk. If we calculate this, it translates to about 10 million MG Cybersters produced. In that case, only one car’s cell may have a safety concern. Such safety assurance is rare in the industry.
The MG Cyberster’s battery pack uses nano-grade aerospace insulation materials and high-temperature ceramic fire-retardant materials. These materials prevent thermal runaway from affecting other cells and the battery pack. They keep the faulty cell in a sealed isolation space.
The battery pack uses water cooling technology. This is the main cooling method today. The design includes a lateral automatic explosion-proof pressure relief valve and an active heat dissipation system. If the battery pack experiences thermal runaway, it can quickly relieve pressure. High-temperature gas will vent from the side and not enter the cockpit.
As a responsible car company, MG ensures every battery pack is traceable. It maintains strict records and photos at every production stage. The entire battery pack receives 24/7 safety monitoring. It can detect issues before thermal runaway occurs, preventing problems before they arise.
Talking about technology is one thing. Practice tests the truth. The MG Cyberster’s battery underwent extensive testing. Take the puncture test, for example. The national standard requires one needle to puncture the battery and remain for 30 minutes without catching fire. The MG Cyberster’s battery faced two needles and stayed safe for 24 hours. It far exceeded the national standard.
The MG Cyberster has sold over 300,000 units worldwide. This means over 300,000 battery packs serve owners. So far, it has achieved zero self-ignition and zero thermal runaway, highlighting the excellence of the Magic Cube battery. More importantly, this model offers a lifetime warranty on the three electric components. There are no mileage limits and no restrictions on the first owner. This approach ensures users can enjoy peace of mind. Such a business and service philosophy resonates well with customers.
