In October 1936, the three main forces of the Red Army converged, marking the successful conclusion of the Long March. 90 years later, in the "Re-walking the Long March" event hosted by People's Daily New Media, Changan CS55 Blue Whale Super Engine Hybrid and Eado Blue Whale Super Engine Hybrid, equipped with Sunwoda Power battery, set off with the team. They traveled from Jiangxi through Guangxi, Guizhou, Yunnan, Sichuan, Ningxia, Gansu, Shaanxi, 8 provinces/regions, covering nearly 8,000 kilometers. The wheels retraced the path of our ancestors, but this time there was another silent yet critical "companion" in the fleet — the battery. 8,000 kilometers, what does it mean for a power battery equipped in a new energy vehicle? It is continuous high-altitude climbing, frequent long downhill sections, high temperatures and sudden rain, temperature control and range tests under severe altitude fluctuations, all of which must be answered under complex operating conditions. The journey ended, the fleet completed the crossing, the battery performed steadily throughout. This is almost the most real, most severe "road test" a power battery could encounter, and the one submitting the answer sheet is Sunwoda Power, one of China's four "Global Tier 1 Power Battery Manufacturers". For history, this is a tribute-style revisit; for the industry, this is more like a field inspection carried out in real road conditions.

Use long-distance treks to verify laboratory parameters

The Red Army measured this road with their feet, while today people use driving "Re-walking the Long March" to remember the path taken. Although the route changed slightly, the harshness of the geographical environment has not changed: winding roads on the Yunnan-Guizhou Plateau, high altitudes in western Sichuan, gullies of the Liupan Mountain and Loess Plateau, almost concentrating the working conditions most "feared" by electric vehicles on the same road. Altitude difference, day-night temperature differences, and continuous slopes, harsh conditions that are difficult to assemble in a single test, are completely connected on this Long March road. What is even more rare is that running on this road is not a laboratory prototype, but mass-produced products equipped in batches. Precisely for this reason, the full-process stability of Sunwoda Power battery carries more weight. In the nearly 8,000-kilometer long-distance trek, battery charging and discharging, temperature control, consistency, etc., all withstood the test. For batteries, the hardest part is not a certain extreme moment, but making every ordinary moment on the road reliable. Having the courage to verify laboratory data with a long-distance trek full of extreme operating conditions is itself the foundation of the enterprise for its products.

Behind stability lies invisible "hard skills"

The two models, Changan CS55 Blue Whale Super Engine Hybrid and Eado Blue Whale Super Engine Hybrid, which "Re-walking the Long March" with the team this time, are both equipped with Sunwoda Power battery. This enterprise, integrating cells, modules, BMS and PACK production, sales, and R&D, has technical tags revolving around four words for a long time: Super Fast Charging, Super Safety, Super Durability, Super Anti-freezing. Abstract tags, when put on "Re-walking the Long March", get specific footnotes: Can it start smoothly under low temperatures, is temperature control reliable during continuous climbing, is performance the same as new after repeated charge-discharge. It is understood that Sunwoda Power HEV batteries can achieve -30°C super-low temperature cold start, 10 years 300,000 kilometers life, can also achieve 70C pulse discharge, super 3 times national standard bottom protection, cumulative delivery has broken through 1 million units, relying on Postdoctoral Research Workstation, Guangdong Province Fast Charging Power Battery Key Laboratory and other platforms for continuous accumulation. While HEV and pure electric tracks are laid out in parallel, the enterprise has also reserved next-generation technologies such as solid-state batteries and sodium-ion batteries. Technical leadership has never been just about constantly refreshing parameters on the stage, but more about throwing parameters into real complex road conditions to see if they "tell the truth".

The "New Long March" of power batteries relies on down-to-earth work

Pulling the eyes away from this road, Sunwoda's growth trajectory itself is like a "Long March": from 1997 starting with consumer batteries, to 2014 laying out power batteries; from supplying Renault-Nissan fixed points, to entering supply chains of mainstream car companies such as Li Auto, Chery, GAC, SAIC, to HEV hybrid batteries ranking first in Chinese installations for 5 consecutive years, and topping global installation volume in Q2 2026. Its production bases were built from Huizhou, Nanjing in China all the way to Hungary, Morocco, Thailand, and marketing agencies were established in North America, Europe, Asia, sending Chinese batteries to global car companies' production lines. From power batteries to energy storage systems, Sunwoda Power's business map is also continuously expanding. Every step is not easy, but every step counts. "Fear no hardships, down-to-earth, forge ahead", these 12 words in the context of new energy vehicle industry are exactly the daily life of battery manufacturers: not chasing wind tunnels, not shouting slogans, making the reliability of a battery ultimate, letting new energy vehicles run further and more stably. 90 years later "Re-walking the Long March", the significance is far more than "walking it again". When the fleet equipped with Sunwoda Power battery drives nearly 8,000 kilometers, it completes both a tribute to history and an answer sheet facing the future. The confidence of China's new energy vehicle industry is accumulated by countless down-to-earth links. This road, back then, was opened by the will of ancestors; today, it is paved step by step by the industry using technology. The road ahead is still long, but every step counts. This is also the vivid landing of the Long March spirit in the new energy vehicle industry.
