-
02
Standard container for oversea transportation
All-in-one design, side by side mirror layout, reduces the overall project footprint by 30% compared to traditional solutions.
-
03
3D thermal system design
Temperature difference between battery cells≤ 2℃, system life cycles increased by 1000 times.
-
04
"4+1" safety design
Insulation between battery cells, pack liquid electrical isolation, cluster electrical isolation, physical isolation in the container, and intelligent warning throughout the station to avoid fire risks.
