Drivers in cold climates have long been concerned about how batteries perform in freezing temperatures. Most batteries tend to lose power as the temperature drops, which can leave drivers stranded or facing long charging times. Contemporary Amperex Technology Co. Limited (CATL) has introduced an innovative solution to address this issue.
During a notable event, the company launched the Tectrans II battery series, featuring the first mass-produced sodium-ion battery specifically designed for light commercial vehicles. This advancement is significant for small business owners utilizing light and micro-trucks. Unlike traditional lithium-ion batteries found in most electric vehicles, these sodium units perform exceptionally well in cold conditions.
CATL reports that these batteries remain functional and can still be charged in temperatures as low as -22°F. Remarkably, even at this frigid temperature, the batteries retain 90% of their usable energy, alleviating concerns for delivery drivers operating in harsh winter conditions.
The sodium-ion battery designed for these small vans and trucks boasts a capacity of 45 kWh. While sodium batteries are typically less energy-dense than their lithium counterparts, they are considerably cheaper to produce due to the widespread availability of sodium. CATL anticipates that 2026 will mark the year these batteries become prevalent, with plans to integrate them into applications ranging from electric vehicles to large-scale energy storage systems. The company envisions a future where sodium and lithium batteries collaborate as a complementary power solution for the next generation of transportation.

This model can charge from 20% to 80% in just 30 minutes, even in temperatures as low as 5°F. For regions experiencing extreme heat, the company has developed a high-temperature version that can add 60% of its range in a mere 18 minutes, boasting a lifespan of 5,000 charge cycles even at a scorching 113°F.
For long-haul drivers, the Tectrans II series includes an impressive long-range option. This robust battery has a capacity of 253 kWh, providing enough energy for a commercial vehicle to travel 497 miles on a single charge. With this substantial capacity, CATL aims to demonstrate that electric trucks can undertake long journeys without the need for frequent charging breaks.
Finally, the company introduced new battery-swapping options, catering to drivers who prefer to exchange batteries rather than waiting for a charge. CATL unveiled three different "swap blocks": the #20 block with 42 kWh, the #25 block with 56 kWh, and the #35 block with 81 kWh of capacity.
With the introduction of these various battery sizes and the groundbreaking sodium-ion technology, CATL is facilitating a smoother transition for companies switching their fleets to electric power, regardless of weather conditions. The diversity of battery options and technologies signifies a departure from a "one-size-fits-all" approach to battery design in the industry.
