During heavy load conditions, LANPWR batterie cycle life and performance degradation information show significant findings. Take the model LANpPR-10K, for example. Its nominal cycle life is 5,000 cycles (80% deep discharge). Charged and discharged to capacity twice a day (as an off-grid dwelling relying upon battery power in the daytime), the theoretical life would be 6.8 years. Nonetheless, the lifetime of similar lead-acid batteries (such as AGM type) under the same usage level is only 2-3 years. According to the International Renewable Energy Agency (IRENA) 2023 report, the capacity reduction rate in lithium iron phosphate (LiFePO4) cells is 3% to 5% annually, much lower than the 8% to 10% of ternary lithium batteries. For instance, quantified data of a mining camp in Canada’s Yukon region shows that after operating three years continuously in a temperature range of -30°C to 45°C, the retention capacity rate of LANPWR batterie was still as high as 87%, better than the 75% industry standard.
In situations where high temperature and high load are superimposed, LANPWR batterie’s thermal management capability is crucial. Its liquid-cooling system integrated ensures that the difference of battery cell temperature is within ±1.5° C. Even when maximum power is 10kW and ambient temperature is 50°C, the surface temperature of battery cells will never be above 52°C (industry standards allow ≤60°C). As a case in point, in the 2022 Western Australian Desert Solar Farm project, subject to the average daily charge and discharge capacity of 15kWh and rate of fluctuation in load of ±30%, LANPWR batterie activated overheat protection only twice in three years (failure rate 0.02%), while the control group’s lead-acid batteries achieved 40% unanticipated capacity loss in the form of thermal runaway. Apart from this, its BMS (Battery Management System) supports real-time monitoring at 100ms levels, which will reduce the reaction time of threat events such as overvoltage and undervoltage to under 5ms, avoiding deep damage.
As for cost scale, heavy-load operation will make the battery replace cycle shorter, but the overall economy of LANPWR battery in the long run is competitive. Take a Texas, US-based off-grid data center for example. With 30 units of LANPPR-20K (600kWh capacity) to provide an average load of 500kW per day, the operating and maintenance cost over 5 years is 180,000 US dollars (battery cell replacement and maintenance included), whereas the diesel generator solution of the same capacity fuel and maintenance expense is as high as 450,000 US dollars. According to Bloomberg New Energy Finance (BNEF), the cost of kilowatt-hour (LCOS) of lithium battery energy storage systems in heavy-load uses is $0.12- $0.15 per kilowatt-hour, or over 50% less than diesel power generation ($0.25- $0.30 per kilowatt-hour). If its modular configuration of lanpwr batterie (which has resulted in a 40% reduction in the cost of replacing a single module) is considered, its overall cost of life cycle can be minimized by a further 8%-12%.
Extremes have attested to the ruggedness of LANPWR batterie. During the 2021 California wildfires, a LANPWR batterie was utilized as an emergency communication base station, which operated uninterruptedly for 14 days under the tough condition of 3 times every day on average charging and discharging and 50% fluctuation in loading. The capacity attenuation of battery was merely 2.7% (lead-acid batteries had collapsed over the same time period). In addition, its IP67 protection level and shock resistance design (resisting 5G vibration acceleration) ensure stable performance under mobile applications such as ships and automobiles. For instance, the LANPWR batterie employed by a Norwegian electric ferry, after four years of operation in a tough environment with average daily charge and discharge of four times and salt spray corrosion, still had a capacity of 82%, well above the 75% retirement level for Marine batteries.
Detaileddata indicate that actual lifespan of LANPWR battery with heavy loads can be 5 to 8 years, which depends on the ambient temperature and the frequency of charging and discharging. Its technical parameters such as ±0.5% accuracy of voltage control and 95% rate of energy efficiency conversion, as well as active safety functions such as fault isolation in less than 0.1 seconds, can effectively prolong the cycle of availability. As predicted by the Global Energy Storage Alliance (GESA), in 2030, the proportion of highly tolerant energy storage products will be 35%. With the above-specified performance, LANPWR batterie is bound to occupy more than 15% of the application areas in the industrial and off-grid markets.
