Li-Rack is a medium-sized lithium ion battery system made in India for multi-family houses, commercial applications, and projects with demanding storage needs. Li-Rack lithium ion battery made in India is based on the active cell balancing technology for best performance and life expectancy, and remote monitoring via internet. The Li-Rack system is an ideal made in India model of the lithium ion batteries that we should use today. It is a green solution and will help us reduce our carbon footprint on mother Earth. It is internet ready storage systems and first of its kind. The chemical composition is intrinsically safe in their chemistry, that is to say, they can neither burn nor explode.
The life expectancy of Li-rack, made in India lithium ion battery is 20years which is very high as compared to the other systems present in the market. Li-rack lithium ion battery made in India can be installed everywhere that is in rural areas, Hotels, Hospitals, industries, electric vehicles, and last but not the least in our homes. The range we offer is from 3.5KWh to 55.0KWh, although multiple batteries can be combined for large scale requirements. It is absolutely maintenance free.
Even without subsidies for own-use or grid feed-in tariffs, Li-Rack lithium ion batteries made in India are a safe investment into your energy independence. The amortization (ROI) is much better than on a standard PV system making the Li-Rack made in India lithium ion battery systems economically attractive.
*Serial scalable for higher voltages
*Parallel scalable for higher capacities
Due to their physicochemical properties lithium cells call for a battery management system (BMS), to maximize cell capacity and to equalize the cells voltage levels. Most available BMS for Lithium Batteries realize passive balancing for it. Excessive energy from single fully charged cells will be wasted as heat, while other cells still get charged. For this reason passive balancing yields an efficiency of 0%! Over the years of operation the single cells characteristics drift apart. A chain is only as strong as its weakest link - the same applies to a combination of cells: the weakest cell is responsible for decreasing Lithium Battery capacity. So much for the state of the art...
And now the future comes home! Our in-house developed BMS Lirack 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.
Lirack also enables communication of the battery with the inverter via CAN interface for standard inverters, as well as internet based remote monitoring of the battery independent of the inverter. 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 and LiRack batteries.
With internet-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. The system is capable of clustering, that is, several batteries with Lirack can be connected parallel to increase capacity. Communication with the inverter via CAN is realized with a LiMaster module.
