FAW Jiefang Group Co., Ltd. and HiNa Battery Technology Co., Ltd., a domestic leader in sodium-ion battery (SIB) technology, have successfully finished systematic full-condition testing of a sodium-ion battery-powered heavy-duty truck, marking a landmark breakthrough in the commercial vehicle deployment of sodium-ion cells. The joint solution addresses two core pain points plaguing electric heavy trucks: severe capacity degradation in low temperatures and slow recharging speeds.

Upholding an innovation-driven mindset and open collaborative development philosophy, FAW Jiefang carried out this rigorous joint testing to integrate complete vehicle manufacturing expertise with cutting-edge sodium-ion battery technologies.

The test vehicle is the Jiefang J6P all-electric tractor equipped with a high-capacity 339 kWh sodium-ion battery pack. Over nearly seven months of trials accumulating over 15,000 kilometers of real-world road testing, engineers conducted comprehensive bench tests, vehicle durability evaluations, power performance assessments, and extreme-temperature validation under both high heat and frigid cold. The all-scenario, high-intensity qualification fully verified the model’s robust operating stability, reliable safety performance, and strong adaptability to diverse logistics operations.

Combining FAW Jiefang’s decades-long heavy-duty vehicle manufacturing prowess and HiNa’s proprietary sodium-ion battery advantages, the J6P sodium-ion electric tractor delivers three core industry-leading strengths tailored to commercial transport demands:

1. Ultra-wide temperature tolerance for frigid climates

   The battery retains over 90% of its usable capacity at an extreme -40°C, eliminating the sharp range loss typical of lithium-ion heavy trucks in winter. The technology unlocks electrification opportunities for freight fleets operating in cold northern and northwest China regions.

2. High operational efficiency and ultra-long cycle life

   Full fast charging is completed within 20–25 minutes to cut downtime and boost fleet turnover. The sodium-ion cells achieve over 8,000 charge-discharge cycles under fast-charging conditions, far exceeding mainstream industry benchmarks.

3. Superior thermal stability and driving safety

   Sodium-ion battery materials feature mild chemical reactivity and outstanding thermal stability, perfectly matching the high-load, all-weather, high-safety operational requirements of heavy commercial vehicles.

As global energy transition accelerates, sodium-ion batteries stand out as a critical green energy solution with exceptional wide-temperature performance, abundant raw material supply, and strong cost competitiveness. HiNa Battery will continue to develop safe, efficient, universal energy storage products to advance low-carbon transformation across transportation sectors.
