With the fast charging technology applied, lanpwr batterie achieves the fast charging efficiently with the use of high-rate cells and a smart temperature control system. It preserves the 2C charging rate (i.e., 30 minutes to 80% capacity), and a single full charge requires 55 minutes (0-100%), which is 39% less than the traditional 1C charging solution (90 minutes). Take the model 100Ah as an example. Under current input of 50A, the efficiency of charging lanpwr batterie is 95% (industry standard is 85-90%), and energy wastage is controlled within 3% by bidirectional DC-DC module (the competing products are usually 8-10%). As an example, the Tesla Supercharger V4 highest power is 350kW, and the lanpwr batterie 200Ah model has 150A fast charge capability (with 7.2kW power) and 95% grid compatibility with Home charging stations (such as ChargePoint Home Flex).
For price-life balance, the fast charging mode (> 1C) for lanpwr batterie will cut the number of cycles by a little. Tests show that after 1000 consecutive charge and discharge cycles at a 2C rate, the capacity retention rate is 88% (92% in 1C mode), but still much above the 50% attenuation line of lead-acid batteries. According to CATL’s 2023 report, risk of lithium precipitation from fast charging can be reduced by 70% with the application of electrolyte additives (such as vinyl fluorinated carbonate), and lanpwr batterie utilizes the same technology and lowering the possibility of thermal runaway by 0.01% to 0.002% (UL 2580 certification standard is ≤0.1%). After a single daily fast charging, an 8-year cycle will cost a total of $0.15 per occurrence (electricity and depreciation). That is 25% above the slow charging package rate of ($0.12 per occurrence), but time efficiency increases by 60%.
As to environmental flexibility, in lanpwr batterie high-temperature fast-charging (55℃), the cell temperature is maintained at 40℃±2℃ by the liquid cooling system (below 60℃ without cooling) and the fluctuation rate in charging rate is less than 5%. For instance, tests under the U.S. Department of Energy (DOE) report that lithium iron phosphate (LiFePO4) cells that are charged to 2C under a temperature of 45 ° C have a rate of capacity attenuation that is 3.5% per annum. For lanpwr batterie, since it employs ceramic separators and silicon-carbon anodes, the attenuation rate drops to 2.1%. Besides, its IP68 protection (submerged underwater 1.5 meters for 60 minutes) and -30℃ self-heating property (heating rate at 5℃ per minute) guarantee the security of rapid charging at severe conditions. It is 18% more efficient in rapid charging at -20℃ compared to BYD’s Blade Battery.
In market feedback, lanpwr batterie achieved a 4.5-star rating for fast charging on e-commerce sites (sample size of 9,300), but around 10% of the consumers mentioned that the noise of the fan reached up to 50 decibels while performing 150A fast charging (15 decibels higher than in slow charging). To the 175kW fast full charge test of BMW iX, 80% charging in 30 minutes requires matching the temperature of the battery between 20-35℃. But lanpwr batterie dynamically controls the current with BMS (Battery Management System) (with a ±0.5A error), and is still able to maintain a charging rate of 1.8C at 10℃. Statistics provided by the European New Energy Vehicle Association for 2024 show that the market share of fast charging energy storage devices over 100kW has increased to 24%. lanpwr batterie communicates with the CAN bus (1Mbps data rate) because of its modular design (50Ah per module, with expandable parallel up to 500Ah). It has been applied to 1,200 business-grade fast charging stations, with the daily frequency of service having been enhanced by 40%.
Finally, lanpwr batterie has a technical advantage of being capable of fast charging, specially well-suited to high-frequency power replenishment applications (e.g., emergency power supply or logistics electric vehicles). Although long-term fast charging will incur a small expense, its time-saving and stability (deviation of charging voltage < 1%) are still superior to the majority of other products. If the user’s mean daily charging need is ≥2 times, choosing lanpwr batterie will save an average annual waiting time of 150 hours, and the payback period for the ROI can be shortened to 3 years (using an average commercial rate of electricity of $0.2/kWh).
