Large capacity prismatic LiFePO4 cells are the trend for energy
storage batteries,EVE is one of the few manufacturers that can officially mass
produce battery cells with a capacity of over 500ah.
Significantly reducing the number of battery cells: When building
an energy storage system with the same capacity, the required
number of battery cells can be reduced by about 55% compared to
using 280Ah battery cells. This means:
Simplified PACK integration: The number of components (such as connectors, wiring harnesses,
fasteners) has been significantly reduced, reducing the complexity
and fault points of the system.
Improving volumetric energy density: The system is more compact, which helps to save floor space.
The direct benefit of capacity is cost optimization:
Reduce initial investment costs: As the number of battery cells decreases, the corresponding costs
of BMS acquisition channels, structural components, installation
hours, etc. will also decrease.
Significantly reducing LCOS: This is the most crucial advantage. By simplifying the system,
energy loss has been reduced, system efficiency has been improved,
and the cost per kilowatt hour of energy storage throughout the
entire lifecycle of the power station has been reduced, bringing
higher investment returns to the owners.
Cycle life exceeding 8000 times: Official data shows that the battery cell can have a cycle life of
over 8000 times under standard conditions. This means that in a
typical application scenario of one charge per day, it can
theoretically be used for over 22 years, demonstrating extremely
strong durability.
Excellent calendar lifespan: With a well-designed temperature control management system, its
calendar lifespan can reach over 20 years, meeting the needs of
long-term energy storage projects.
EVE Energy applies its accumulated safety technology in the fields
of consumer batteries and power batteries to Mr. Big battery cells:
Double valve design of "explosion-proof valve+safety valve": can release internal pressure more effectively and quickly,
preventing thermal runaway.
Low impedance anti-corrosion top cover: improves the reliability of the battery cell.
High strength shell design: ensures the structural integrity of the battery cell in long-term
use and harsh environments.
Through authoritative safety certification: the product complies with international safety standards such as
UL 1973, UL 9540A, IEC 62619, providing access guarantee for its
application in the global market.
