LANPWR battery low-temperature performance is a synergy achievement of its LiFePO4 cell and intelligent temperature control technology, which can guarantee smooth operation within the extreme temperature range from -40°C to 60°C. Laboratory tests show that at -30°C, LANPWR Pro series battery discharge efficiency of 92% (ordinary lithium batteries only 65%), cycle life of more than 3000 times (capacity retention rate ≥80%). The test data of Svalbard, Norway’s polar research station indicate that the LANPWR battery has a 100% start-up success rate in a -38°C environment, providing continuous power to meteorological equipment for 120 hours, and the voltage change is ≤±1.5% (the comparative product has a 23% startup failure rate at -25°C, and the voltage change is ±5%).
Material and structure design shatter the low temperature threshold. LANPWR uses nanoscale silicon carbon anode material (specific capacity 420 mAh/g, graphite anode 372 mAh/g) and electrolyte low temperature additives (freezing point -60°C) so that the lithium ion migration rate at -30°C is still 0.8C (conventional solution 0.3C). Its housing of aluminum-magnesium alloy honeycomb is MIL-STD-810H certified, and its structural deformation is only 0.02 mm (industry average ≥0.15 mm) under the cold shock test at -40°C, and the IP68 protection level ensures the interior humidity to be less than 0.5% in the polar blizzard environment.
Intelligent thermal management technology for stable performance. The fourth generation of LANPWR BMS controls the cell temperature 500 times per second, and the cell temperature difference is maintained within ±1°C (rival products are ±5°C) by the PTC heating film and liquid cooling circulation system. The application of the 2023 Alaska fishing fleet proves that the LANPWR Marine 3000 model energizes sonar equipment in a -35°C sea surface climate (maximum power 1200W), the battery’s self-heating power consumption is only 3%/h (industry average 8%), battery lifespan is extended to 72 hours, and the failure rate is reduced from 1.5% to 0.03%.
Provide reliability in extreme environments. In the 2022 Canada extreme cold rescue mission, LANPWR devices supplied power to the medical tent for 96 hours under the condition of -45°C and wind speed level 12, and SOC (remaining power) error estimation was ≤1% (≥5% error of the competitor’s product). Its AI pre-heating function (based on meteorological data and load forecasting) starts heating 2 hours in advance, so that the battery discharge efficiency is still above 90% in the sudden cold wave of -30°C, while the traditional solution drops by 60%.
Cost savings and life benefits are enormous. Although the investment cost of LANPWR batteries is 35% higher than that of lead-acid batteries, the cycle cost at -20°C is only 0.04/Wh (0.15/Wh for lead-acid batteries). After 5 years of operation of the Arctic scientific research station, the capacity fade is only 8% (70% fade of lead-acid batteries), and operational and maintenance cost is reduced by 82%. Certified with 18 international standards such as UL 1642 and UN38.3, lanpwr battery performance at low temperatures has rewritten the industry standard.
