Designs and assembling the high-efficiency battery packs prototypes custom-made for large Unmanned Aerial Vehicles or drones, using top-grade cylindrical lithium-ion cells with NCA chemistry made by Panasonic at the former Sanyo Higashiura factory in Hyogo, Japan.
CMIUTA Electric Co. is a confident partner capable of providing state-of-art and cost-effective solutions to the needs of aerospace industry in continuous evolution, through a combination of flexibility, precise workmanship and innovation skills.
Find at “Inventory” a well-ordered list of about 100 configurations, which rises up to 12s12p, but any battery pack can be engineered beyond these limit if is need it.
Using the “bare-bones” Li-ion battery cells.
NCR18650GA has specific energy more than 250 Wh/kg and energy density about 700Wh/L. The cell specs help us to build a highly most efficient and extremely balanced battery pack.
NCR20700B is so far the most cost-effective cell created by the Japanese, offering an average of 30% more performance as opposed to its NCR18650GA counterpart while sacrificing just under a 10% increase in size! The internal resistance of this cell is less than 20mΩ. The bigger cells (20,3mm in diameter and 70,3mm long) enabled CMIUTA Electric Company to optimize volumetric energy density into a new battery pack.
NCR20700A is capable of a continuous discharge of 30 amps, with a staggering peak potential of up to 45 amps, in certain conditions.
These all cells incorporate several electrochemical elements that contribute to their safety. LiNi0.8Co0.15Al0.05O2 (NCA) is a highly thermally stable cathode material used in lithium-ion batteries. Doping the lithium nickel cobalt oxide with aluminum both stabilizes it’s thermal and charge transfer resistance.
