Modern vehicles place greater demands on their 12V battery systems than conventional starting alone. Automatic start-stop functions, frequent urban driving, onboard electronics, and repeated high-current engine starts can accelerate battery wear. We see sodium-ion technology as a strong option for these demanding automotive scenarios. As a sodium-ion batteries manufacturer, we develop batteries around high cycle life, fast charging, high-current output, and practical vehicle integration.
Start-Stop Systems: A Natural Application for Sodium-Ion
Automatic start-stop systems repeatedly shut down and restart the engine during traffic stops. This reduces unnecessary idling, but it also creates a much more demanding battery duty cycle than traditional driving.
We therefore consider start-stop vehicles one of the most promising applications for sodium-ion battery for cars. The battery must provide reliable starting power while also supporting electrical loads when the engine is temporarily off. High cycle life and rapid energy recovery become essential considerations for maintaining consistent start-stop operation.
Urban Cars Benefit from High Cycle Life
City driving can involve dozens of stops within a single journey. Traffic lights, congestion, parking queues, and short-distance trips repeatedly activate the start-stop system, increasing the number of charge and discharge events.
Our H6/LN3 is designed for this operating pattern, with a specified start-stop cycle life of 180,000 cycles. This provides a substantial endurance target for vehicles exposed to frequent engine restarts. For fleet operators and automotive service businesses, long cycle life can also reduce the frequency of battery replacement and associated maintenance activity.
H6/LN3 Delivers Strong Starting Performance
Cycle life is only useful when the battery can also deliver sufficient power at the moment the engine needs to restart. We designed the H6/LN3 to combine high starting output with a practical automotive form factor.
The battery provides 12V voltage, 750A CCA, and 480Wh energy. Its dimensions are 278 × 175 × 185 mm, with a weight of 6.5 kg. The product corresponds to the L3 AGM case size, making these specifications useful reference points for business buyers evaluating vehicle compatibility and electrical requirements.
Frequent Stop-and-Go Driving Calls for Fast Charging
A start-stop battery does not simply provide power for starting. Between engine-off events, it needs to recover energy while the vehicle is running. Frequent stops can therefore make charge acceptance particularly important.
Our H6/LN3 features 5C fast-charge capability. We see this as particularly relevant to vehicles operating through congested urban routes, where the time between consecutive engine stops may be limited. Faster charging can help the battery recover energy more efficiently during available driving periods, supporting repeated start-stop operation.
High-Temperature Driving Is Another Key Use Case
Automotive batteries can encounter substantial heat, especially in engine-compartment environments and during operation in hot climates. For business automotive applications, thermal performance should therefore be evaluated alongside capacity and starting current.
The H6/LN3 is specified for high-temperature operation up to 80°C. This capability makes it particularly relevant to vehicles exposed to demanding thermal conditions. We combine this temperature capability with long cycle life and fast charging to create a battery platform intended for repeated automotive use rather than occasional starting alone.
Fleet Vehicles Can Amplify the Benefits
Fleet vehicles often experience more demanding duty cycles than privately owned cars. Taxis, rental vehicles, delivery fleets, and other high-utilization passenger vehicles may spend much of their operating time in traffic and perform frequent starts throughout the day.
For fleet managers, we believe battery selection should therefore consider total operating workload rather than only the initial purchase price. A sodium-ion battery for cars can become attractive when high cycle requirements, frequent starting, fast charging, and reduced maintenance are important factors in fleet operation.
