Do Sodium-Ion batteries support fast charging?
Absolutely, and their C-rate performance is outstanding. Due to the weaker solvation effect of sodium ions in the electrolyte and higher conductivity, Na-Ion batteries can typically charge to 80% capacity in just 15-20 minutes. This provides immense value for high-frequency commercial fleets or energy storage projects requiring rapid power response.

Are Na-Ion BMS configurations and communication protocols (like RS485 / CAN) compatible with Lithium batteries?
Yes, the hardware architecture and external communication protocols (RS485, CAN, Bluetooth, etc.) are completely universal. Existing system integration and inverter matching experience can be seamlessly applied.
The main difference lies in the underlying BMS algorithms and parameter settings. The nominal voltage platform of Na-Ion (approx. 2.8V-3.1V) and charge/discharge cut-off voltages differ from LFP. Additionally, the discharge curve has a more noticeable slope. Therefore, we recalibrate the SOC (State of Charge) estimation logic and overcharge/over-discharge protection thresholds specifically for Na-Ion cells to ensure optimal safety and performance.

What is the cycle life of a Sodium-Ion battery?
At the current stage of mass production, Na-Ion batteries typically deliver a cycle life of 2,000 to 4,000 cycles. While not yet at the level of high-end LFP (which can reach 6,000-8,000 cycles), it vastly outperforms traditional lead-acid batteries (which usually only offer 300-500 cycles), making it more than capable of handling most light-to-medium duty, high-frequency commercial applications.

How do Na-Ion batteries perform in extreme temperatures?
A wide operating temperature range is one of the core selling points of Na-Ion technology. They excel in cold environments, retaining over 90% of their discharge capacity at -20°C, effectively solving the LFP issue of capacity drop in cold areas. Meanwhile, in high-temperature environments (such as 45°C-60°C outdoor conditions in tropical regions like Indonesia), Na-Ion also demonstrates outstanding thermal stability and safety.

How does the energy density of Sodium-Ion (Na-Ion) batteries compare to mainstream LiFePO4 (LFP)?
Currently, commercialized Na-Ion batteries typically offer an energy density between 120-160 Wh/kg. While slightly lower than mainstream LFP cells (usually 160-200 Wh/kg), it perfectly meets the requirements for applications that don't demand extreme range. With ongoing technological iterations by major tier-1 cell manufacturers (such as CATL, EVE, and REPT), the energy density of Na-Ion is expected to exceed 200 Wh/kg in the near future.
