With a capacity of 6.9MWh, Honeycomb Energy releases the Dagger liquid-cooled energy storage system and upgraded version of the Dagger energy storage battery
According to news from this website on April 11, Honeycomb Energy announced today that it has released 350Ah and 730Ah large-capacity energy storage dagger batteries at the 12th Energy Storage International Summit and Exhibition (ESIE2024, Beijing), as well as the world’s first 6.9MWh -20-foot dagger liquid-cooled energy storage system. The following introduction is attached to this site:
Upgraded version of the dagger energy storage battery
Honeycomb Energy first released the new "Flying Stacking Dagger" energy storage battery core upgrade product: L500-350Ah , L500-730Ah Flying dagger energy storage battery.
The L500-350Ah energy storage cell is based on the 325Ah energy storage cell launched by Honeycomb in 2023. The size remains unchanged, the system is upgraded, the energy density is increased by 7%, and the energy of a single cell reaches 1120Wh, with a cycle life of more than 11,000 times. Compared with the previous generation product, the BOM cost is reduced by 13.3% and the manufacturing cost is reduced by 6.2%. Based on the short knife process, it has high heat dissipation efficiency, more uniform temperature distribution, and low temperature rise characteristics.
L500-730Ah energy storage battery is based on the L500-350Ah energy storage battery, is thicker in size and doubles in capacity , the energy density reaches 420Wh/L, and the cycle life exceeds 11,000 times. The L500-730Ah energy storage cell is claimed to be able to significantly reduce the use of PACK components, increase the volumetric energy density of the energy storage system, achieve higher BMS data collection and monitoring accuracy, and have the advantages of more efficient grouping and significant cost reduction.
When charging, the L500 energy storage battery core can be fully charged to 3.65V under the specified current, using a high-temperature resistant steel needle with a diameter of 5mm. , penetrated from the direction perpendicular to the battery at a speed of 0.1mm/s, and the steel needle stayed in the battery. Observed for 1 hour, there was no smoke or fire during the entire battery core acupuncture test.
Dagger Liquid Cooled Energy Storage System
From the perspective of power scenarios, individual energy storage projects are currently entering the GWh era, reducing the area occupied by energy storage projects, saving investment, and increasing the capacity of energy storage systems. and group efficiency has become a trend. At this stage, the mainstream products in the market are generally moving towards 5MWh-20-foot energy storage boxes.
Honeycomb Energy uses L500-325Ah / 350Ah energy storage dagger battery cells to launch a power energy storage product - 6.9MWh dagger liquid cooling energy storage system. The system adopts CTR streamlined design, with 15% fewer parts and 20% less floor space than the mainstream 5MWh energy storage system in the market. It adopts a single-door solution and supports back-to-back arrangement.
According to reports, the 6.9MWh short knife liquid cooling energy storage system can achieve double-sided liquid cooling, The temperature difference of the battery core body is reduced by 40%. In turn, the battery life is increased by 15%.
The above is the detailed content of With a capacity of 6.9MWh, Honeycomb Energy releases the Dagger liquid-cooled energy storage system and upgraded version of the Dagger energy storage battery. For more information, please follow other related articles on the PHP Chinese website!
