OneBox® is a Lithium based battery sysem made in India, it applications in commercial as well as domestic purpose. OneBox® is based on active cell balancing technology for best performance and life expectancy, and remote monitoring via Ethernet. It is an integrated system to give you completely uninterrupted power and zero blackout. It is a flicker free system Which keeps your device safe during power spikes.
The life expectancy of OneBox® is 10 years which is very high as compared to the other systems present in the market. OneBox® systems can be installed everywhere that is in rural areas, Hotels, Hospitals, offices, industries and last but not the least, in our homes. We offer 3 models of OneBox® which are OneBox® Lite, OneBox® and OneBox® premium. It is absolutely maintenance free and can be installed easily (D-I-Y Solution)
Even without subsidies for own-use or grid feed-in tariffs, OneBox® is a safe investment into your energy independence.
And now the future comes home! Our in-house developed BMS OneBox utilizes active balancing. The states of charge of a battery's cells are being equalized continuously among one another. That is to say, energy from higher charged cells will be transferred to lower charged ones. This results in 90% efficiency, compared to 0% with passive balancing. Additionally, active balancing increases life expectancy of Li-cells by more than 30% due to reduced drift of characteristics. Increased energy yield from the charged battery is another positive side effect: with passive balancing the depth of discharge (DoD) should not exceed 70% to provide long life expectancy of the battery. Our active balancing allows for 80% DoD without reduced life expectancy - thus 14% more energy with identical rated capacity.
OneBox® also enables communication of the battery with the inverter via CAN interface for standard inverters, as well as ethernet based remote monitoring of the OneBox®. In this process all relevant data like voltage, state of charge, temperature etc. will be logged and analyzed for each battery on single cell level. For instance, this allows for identification of an early seasoned cell of a battery, and arrange for its prophylactic replacement. Thus, a possible system failure can be avoided.
Regarding the lithium cells we also stand out from the usual market standard - lithium-iron phosphate (LiFePO4). Instead, we use lithium iron yttrium phosphate (LiFeYPO4). The doping with yttrium will increase the cells life expectancy and performance. The conceptual design and chemistry of our Li-cells renders them intrinsically safe, this means in case of a problem the cells can not catch fire. By the way, most cell phone or laptop batteries are not intrinsically safe! Lithium cells are almost completely recyclable. And - in contrast to lead batteries - they do not contain any hazardous material. Lab test demonstrates life expectancy In cooperation with the University of Applied Sciences in Ansbach we have tested our LiFeYPO4 cells under extreme conditions. The lithium cell is discharged to 70% DoD approximately 33 times per day with 1C charge and discharge current. We have exceeded 9000 cycles! The results confirm a very high load capacity and reliability, and verify the superior quality of the cells used for our LiRack batteries.
With ethernet-based remote monitoring you can observe the state of the battery and its single cells independently of the inverter. This enables early identification of problems, change of parameters and analysis of typical battery usage. Active balancing is specially beneficial for second life lithium cells.
