EVE Energy Challenges Zeekr’s Record with Omnicell 6C Battery

Just one day after we learned of Zeekr’s groundbreaking 5.5C ultra-fast charging battery technology, we find that, just hours earlier, EVE Energy revealed its Omnicell 6C battery, which promises even faster charging capabilities. While Zeekr’s new battery allows vehicles to charge from 10% to 80% in 10.5 minutes, EVE Energy’s Omnicell 6C battery reportedly matches and potentially surpasses this with a nine-minute charge time under similar conditions.

EVE Energy’s Omnicell 6C battery, designed for high-end passenger vehicles, can deliver a driving range of 300 kilometers (about 186 miles) after just five minutes of charging at 25°C. This performance is achieved through innovations in reducing internal resistance and enhancing heat exchange efficiency. The battery maintains its fast charging capability even in low-temperature environments, charging from 10% to 80% in 25 minutes at -30°C.

Finding the balance

Johnson Feng, product director at EVE Energy, emphasized the techncal challenges overcome in developing the Omnicell battery, particularly in optimizing the balance between cooling efficiency and internal resistance. The battery’s internal resistance has been reduced to 1.4milliohms, a 20% improvement that allows for rapid charging without compromising on safety. The battery’s design includes a three-sided heat dissipation system, which enhances the heat exchange area by 270%, ensuring stable performance during high-speed charging.

In addition to its fast-charging prowess, the Omnicell 6C battery offers sustainability benefits, including a 10% higher residual value compared to lithium iron phosphate (LFP) batteries, due to the use of nickel-cobalt-manganese (NCM) materials. EVE Energy’s production process is also environmentally conscious, utilizing 100% green electricity and 50% recycled materials, according to the company.

Internal-combustion engine vehicle drivers who are wary of EVs often cite concerns about charging speeds, especially when charging in cold weather. This week’s news from Zeekr and Eve Energy show that battery makers are racing to address those concerns. It’s exciting to wonder how soon until these record-breaking charging speeds are surpassed. It’s almost sure to happen soon.
