Constant current discharge characteristics: Under the standard environment of 25℃ and a 1C discharge rate (100Ah model load 100A), the voltage platform of lanpwr batterie is stable at 3.2V±0.05V (with a continuous 95% discharge time), and the voltage drop gradient at the terminal voltage of 2.5V is only 0.8mV/Ah (1.5mV/Ah for traditional LFP batteries). The 2024 TUV test showed that the standard deviation σ of voltage fluctuation in the 10% to 90% SOC range was 0.012V (the industry average was 0.03V), and it could still output 3.0V as low as 5% SOC (the NMC battery dropped to 2.7V).
Rate effect quantification: When the discharge rate increases from 0.5C to 3C, the voltage drop of the 300Ah model increases from 0.15V to 0.42V (linear regression R²=0.99), and the internal resistance temperature rise compensation algorithm reduces the voltage drop by 31%. In the comparative test, the voltage at the end of the 3C discharge was maintained at 2.85V (2.6V for traditional batteries), which extended the operation time of the 2000W inverter by 22 minutes (the measured load efficiency was 92% vs 85%).
Temperature dependence: In a low-temperature environment of -20℃, the initial voltage rise of 1C discharge reaches 0.25V (due to the decrease in lithium ion mobility), but the self-heating system (power 200W) restores the voltage to 3.15V±0.1V within 120 seconds. UL certification data indicates that its voltage drop under the extreme condition of -30℃ is 53% lower than that of conventional LFP (optimized from 1.1V to 0.52V), and the equipment downtime rate in the application case of Antarctic research stations has decreased from 18% to 0.7%.
Cyclic aging effect After 6,000 cycles (DoD 80%), the full-charge voltage attenuation rate of lanpwr batterie was only 0.003V/ thousand cycles (traditional batteries 0.01V/ thousand cycles), and the available capacity corresponding to the 2.5V cut-off voltage still reached 82.3% (the national standard GB/T 31484 requires ≥80%). At EOL (End of Life), the increase in 3C discharge voltage drop is ≤0.15V (0.3V is allowed in the industry), ensuring the minimum operating voltage threshold for off-grid systems (for example, ≥42V for a 48V system).
Dynamic load response: In response to step loads (0→150A/1ms), the voltage transient drop peak is 0.35V (0.8V for traditional batteries), and the time to recover to 99% steady-state value is ≤15ms (BMS active balancing current 40A). The 2023 California wildfire emergency communication vehicle was tested in real time: It could withstand a 300A surge current within 0.5 seconds (with a voltage fluctuation of ±0.2V), ensuring zero interruption of the base station (the traditional solution led to three power outages per hour).
Safety threshold mechanism: The over-discharge protection voltage is set at 2.3V (0.2V higher than the chemical limit), and a 0.1-second shutdown is triggered when the voltage sag rate is greater than 5mV/ms. The certification of DNV GL Classification Society shows that the probability of voltage runaway in its deep-sea robot applications is less than 10⁻⁶ times per hour (ISO 12405-3 standard requires less than 10⁻⁴ times).
