EVE Energy recently launched the Omnicell 6C fast-charging large cylindrical all-purpose battery specifically designed for high-end passenger cars. EVE Energy says the battery has four key highlights: fast charging, low temperature, physical, and a sustainable life cycle. According to EVE Energy, it can charge from 10% to 80% power in nine minutes at a normal temperature of 25°C (77°F), achieving a driving range of 300 kilometers (approx. 186 miles) after charging for five minutes, and in a low-temperature environment of -30°C (-22°F), charging from 10% to 80% takes just 25 minutes.
“The difficulty in reaching 6C, the C being the measure of battery discharge relative to the battery’s maximum capacity, is to reduce internal resistance while improving cooling efficiency,” Johnson Feng, product director with the EVE Energy Battery System Research Institute, said. “Speeding up the heat exchange while maintaining a low internal battery resistance ensures the battery runs at an optimal temperature.”
EVE Energy said its ongoing process focuses on design and solutions to tackle the technical challenge of reducing the internal resistance of the cell while increasing its heat exchange.
- Internal resistance reduction: According to EVE Energy, technical innovations have been made in electrolyte, separator, and other materials in the battery cell, reducing the internal resistance of the battery cell to 1.4mΩ, which translates to a 20% internal resistance reduction for 10 minutes of fast charging.
- Heat exchange acceleration: VE Energy said Omnicell adopts a three-sided heat dissipation design on the top and both sides of each cell to better control the temperature of the battery cell and further solve the high-voltage current plate heating issue of the battery, allowing the entire battery to maintain a suitable temperature with a heat exchange area to reach 52.3 mm²/Wh, increasing the heat exchange efficiency by 270% when fast charging.
- Meanwhile, the Omnicell boasts sustainable advantages that significantly reduce carbon footprint with extended battery life, EVE Energy said.
- High residual value: Using NCM materials, EVE Energy said Omnicell achieves 10% higher residual value than lithium iron phosphate batteries, and the cylindrical design ensures standardized disassembly and easier recycling. EVE Energy said its cylindrical cell production line uses 100% green electricity in the manufacturing of anode, cathode, and cell, and 50% secondary NCM materials, complying with the latest EU battery laws.
EVE Energy said it has also launched electric vertical take-off and landing (eVTOL) batteries and accelerated the R&D of solid-state batteries.
- Electric take-off and landing (eVTOL) batteries: EVE Energy said its eVTOL battery has an energy density of 320Wh/Kg that can be quickly charged to 80% within 10 minutes, meets 10C high output capacity during the life cycle, and guarantees more than 7,000 cycles, injecting new impetus into the rapidly emerging low-altitude economy.
- Solid-state batteries: Eve Energy said it plans to launch high-power, high environmental tolerance, and safe all-solid-state batteries in 2026, and gradually promote 400 Wh/kg all-solid-state batteries by 2028.
