Sodium-ion Battery Solutions for -40℃ Extreme Cold
Uninterrupted Power for Emergency Lighting & Airport Infrastructure
✓ -40°C Discharge✓ No Heating Needed✓ 5x Lead-Acid Life✓ Zero Maintenance
Pain Points
Challenges in Extreme Cold Power Supply
01
📈
Winter Capacity Loss >60%
Lithium batteries lose over 60% capacity in winter, unable to provide stable power supply in extreme cold conditions.
02
🔥
Heating System Overhead
Auxiliary heating systems increase energy consumption and introduce additional failure points in the system.
03
🔄
Low-Temperature Start Failure
Low-temperature startup failure creates safety hazards in emergency lighting and critical infrastructure.
04
💰
High Maintenance Cost
Frequent battery replacement in cold regions drives extremely high operation and maintenance costs.
Why Sodium-ion
Why Sodium-ion for Extreme Cold?
🛡️
-40°C Discharge, No Heating
Normal discharge at -40°C without any heating system. True cold-climate performance without extra energy consumption.
♾️
5x Longer Than Lead-Acid
Cycle life is 5 times that of lead-acid batteries, reducing replacement frequency and total cost of ownership.
🧩
Maintenance-Free Design
Sealed maintenance-free design ideal for unattended remote installations in harsh arctic environments.
🌡️
Wide Temperature Storage
Broad temperature range for storage and transport with no special thermal control requirements.
Case Study
Real-World Deployments
Case 01
Norway Arctic Circle Emergency Light Retrofit
Background: Outdoor emergency lights in the Arctic Circle region used lead-acid batteries that failed severely in winter, with high annual replacement costs.
Solution: VEKEN cylindrical sodium-ion cells custom-packed to directly replace the original lead-acid battery banks, maintaining the same form factor.
Results:
-20°C capacity retention ≥92% · Replacement cycle extended from 1 to 6 years · O&M costs reduced by 75%
-20°C capacity retention ≥92% · Replacement cycle extended from 1 to 6 years · O&M costs reduced by 75%
Case 02
Regional Airport Lighting Backup Power
Background: Regional airport apron emergency lighting backup power suffered from unreliable lithium battery performance in extreme winter cold.
Solution: VEKEN prismatic sodium-ion cells configured with an intelligent BMS to build a robust energy storage system for critical airport infrastructure.
Results:
Power supply reliability 99.99% · Stable operation at -30°C · Zero failures throughout the year
