CCDR Punching Technology, a new technology developed by JYC Battery, is the first manufacturer in China to apply this technology to energy storage batteries. The alloy of the Punching Plate has a high molecular density that has low internal resistance and corrosion resistance. It is more suitable for high-current charging and discharging and deep cycle use and the battery life is longer
Computer-aided design, combined with element analysis to select a short and superior current path and high utilization rate of active material. JYC analyses the reason for the failure of traditional batteries’grid especially strengthening the design of the upper bar. The upper is thick and the lower is thin, fully considering the current gathering and dispersion process, therefore, the energy-gathering curve grid has the advantage of low internal resistance.
Unique Stereoscopic grid structure with a curve connection between the grid body not only strengthens the solid adhesion of the lead paste but also enlarges the contact area, thus prolonging the battery usage life.
Like the corrosion resistance, CCDR punching grid has a density that the gravity cast grid does not have. The strength and toughness of CCDR punching grid are higher, and it is not easy to break during the subsequent production and use.
Combining high density and high tough-ness with JYC unique alloy formula and process design to further enhance the corrosion resistance of the grid, effec-tively prolong the floating and cycle life of the battery, so the new grid life can be up to 12 years.
From the left data comparison of the 10 cycles, under different charging voltages, the 10 times 100% DOD results from the 2 samples are all over 20 hours. Calculated according to the battery capacity, after 10 cycles, the battery capacity has not declined, and samples with a charging voltage of 14.7V full voltage will have a longer discharge time than samples with 14.4V undervoltage.
Discharge: 0.05C discharge to 10.5V
Charge: Current limiting 13.5A constant voltage 14.4V (14.7V)charge 20H
