The new EVE 356Ah cell represents a clear upgrade over the 314Ah MB31 model, primarily focused on delivering higher energy density and greater efficiency for large-scale energy storage systems. The table below outlines the core differences.
| Feature | New EVE 356Ah Cell | EVE MB31 314Ah Cell | Advantage of 356Ah Cell |
|---|---|---|---|
| Nominal Capacity | 356.25Ah | 314Ah- | Higher capacity per cell, reducing the total number of cells needed for a system. |
| Nominal Energy | 1140Wh (1.14kWh) | ~1004.8Wh | 13.5% more energy per cell, leading to a more compact battery pack for the same total energy. |
| Initial Internal Resistance | 0.15mΩ ± 0.05mΩ | 0.18mΩ ± 0.05mΩ- | Lower internal resistance translates to higher efficiency, less heat generation, and improved overall performance. |
| Weight | 6620g ± 150g | ~5420g - 5600g | Heavier due to higher capacity, but the energy-to-weight ratio is superior as it stores more energy. |
| Dimension (LWH) | 2090*186.6*123mm | ~207.2*173.7*71.7mm | Significantly larger to accommodate the higher capacity cells. |
Superior Electrical Performance
With a lower internal resistance of 0.15mΩ, the new cell is more efficient. It experiences less voltage drop and generates less heat during high-current charge and discharge cycles. This is a critical improvement for applications requiring high power output and contributes to the overall longevity of the battery pack.
Robust and Versatile Thermal Management
The new cell shares the same wide operating temperature ranges as the MB31: charging from 0°C to 60°C and discharging from -30°C to 60°C. This rugged thermal performance ensures reliable operation in a variety of climates without needing intensive thermal management systems.
