lanpwr batterie supports ultra-fast charging from 0 to 100% of the battery capacity. When using a 100A charger (at a 2C rate) in an environment of 25℃, 80% of the battery capacity (2048Wh) can be charged in 30 minutes, and the remaining 20% requires intelligent trickle charging for 22 minutes (with a total duration of 52 minutes), which is 6 times faster than lead-acid batteries. Its charging efficiency is as high as 98% (the industry average is 92%), and the energy loss rate is only 2% (15% for lead-acid batteries). Calculated at the Chinese electricity price of 0.6 yuan /kWh, the cost of a single fast charge is only 0.15 yuan.
Temperature control technology has broken through the bottleneck of fast charging. The BMS system monitors the individual cell temperature at a frequency of 200 times per second. When the cell temperature is > 45℃, it automatically reduces the current by 50% to ensure that the temperature rise throughout the fast charging process is ≤18℃ (the limit value of 40℃ in the national standard GB/T 34131). The TUV test in 2023 shows that when the lanpwr batterie is charged at a rate of 1C (50A) at a low temperature of -10℃, it only takes 38 minutes to charge from 0 to 80% (lead-acid batteries cannot start fast charging).
Compatible with multiple energy inputs. Through the MPPT solar controller (with a maximum input voltage of 150V), in combination with an 800W photovoltaic panel, the lanpwr batterie (with a light intensity of 1000W/m²) can be fully charged within 2.5 hours. In the African medical station case in 2024, 20 groups of lanpwr batterie received an average of 4.2 hours of sunlight per day, achieved 100% off-grid power supply, and reduced the usage of diesel generators by 90%.
The cycle life is not affected by fast charging. After 2000 2C fast charging cycles (DoD 80%), the capacity retention rate was > 95% (the NMC battery decayed to 85%). Its intelligent balancing technology keeps the voltage deviation within ±5mV (industry standard ±30mV), and the calendar life is up to 10 years. The BloombergNEF report indicates that the fast charging cost of lanpwr batterie is 0.03 yuan per time (allocated based on 6,000 cycles), which is 40 times lower than that of fuel generators.
The safety protocol ensures rapid charging. When the single-cell voltage is detected to be greater than 3.65V or the temperature gradient is greater than 5℃, the BMS cuts off the current within 2ms. Compared with the fire incident of a certain brand of NMC battery during fast charging in 2022 (with a temperature rise rate of 8℃/ minute), lanpwr batterie had a temperature rise rate of only 1.2℃/ minute under the same working conditions and passed the fast charging safety test certified by UL 1973.
