Recently, a major breakthrough has been made in the low-temperature performance technology of new energy commercial vehicle batteries. In January 2026, EVE Energy Co., Ltd. joined hands with Foton Motor to complete six extreme low-temperature technical verifications for the LMX open-source battery system in Tianjin, Hailar and Yakeshi. The battery has successfully passed all the tests with excellent performance, which marks a new step in the cold region operation capability of domestic commercial vehicle batteries and effectively breaks the technical restriction of new energy commercial vehicles operating in extreme low-temperature environments.

The verification was carried out by CATARC Information Technology (Tianjin) Co., Ltd. in accordance with the Automotive Extreme Environment Comprehensive Technical Verification Regulation (2025), and the verified vehicle model is Foton Zhilan new energy vehicle equipped with LMX-137kWh battery system. The whole verification fully simulates the actual operation scenarios of commercial vehicles in cold regions, and conducts all-round tests on the battery from cell performance to vehicle system application, with the test temperature as low as -39℃, which fully verifies the reliability and adaptability of the LMX battery in extreme cold environments.

All Six Core Tests Passed, Showing Excellent Low-Temperature Performance

In the six core verification items, the LMX battery has achieved remarkable results in all aspects, and its performance has far exceeded the traditional LFP battery system:

• Low-temperature cold start: At -39℃ and 30% SOC, the vehicle successfully completed the cold start under full load condition, which verified the instantaneous high-power output capacity of the battery and the stability of the whole vehicle system.

• Low-temperature acceleration: Under the extreme conditions of -39℃, 30% SOC and full load, the vehicle only took 22.7 seconds to accelerate from 0 to 60km/h, maintaining a good power output capacity.

• Low-temperature endurance: In the temperature range of -36℃ to -27℃, simulating the distribution scenarios of cold region express delivery outlets and trade markets, the vehicle achieved a cruising range of 191.5km under full load, with a 20% increase compared with the LFP-140kWh system, and the endurance performance was significantly improved.

• Low-temperature charging: At -36℃ to -27℃, the battery completed the charging from 20% to 70% SOC in only 28.0 minutes under full load, with a maximum charging rate of 1.45C and an average charging power of 141.2kW, and the charging efficiency reached 99.3%, realizing efficient and reliable charging in low temperature.

• Cell low-temperature capacity: The LMX 234Ah cell maintained a capacity retention rate of 92.08% at -20℃ and 86.06% at -30℃ (compared with 25℃ normal temperature), which was 28.2% and 62.5% higher than that of the LFP234 cell respectively, with outstanding low-temperature capacity retention.

• Cell low-temperature discharge: At -30℃, the maximum discharge current of the cell was significantly higher than that of the LFP system under different SOC and discharge time conditions. The 10s maximum discharge current at 90% SOC increased by 133.3%, and the 60s maximum discharge current at 30% SOC increased by 66.7%, which effectively guaranteed the power supply of the vehicle in extreme cold and avoided the problem of vehicle breakdown.

Breaking Cold Region Restrictions, Expanding the Operation Territory of Commercial Vehicles

As a key product of EVE Energy's open-source battery system, the LMX battery has always focused on solving the industry pain points of poor low-temperature performance of new energy commercial vehicle batteries. The successful passing of this extreme low-temperature verification not only proves the excellent technical strength of the LMX battery system, but also provides a reliable technical solution for the large-scale promotion and application of new energy commercial vehicles in northern cold regions of China.

For the logistics and distribution industry in cold regions, the high performance of the LMX battery in extreme low temperature means that the new energy commercial vehicles can maintain stable operation efficiency, effectively reduce the operation interruption caused by low temperature, and further improve the transportation efficiency and economic benefits. At the same time, the technical breakthrough of LMX battery also enriches the product matrix of domestic new energy commercial vehicle batteries, and promotes the high-quality development of the whole industry chain of new energy commercial vehicles.

Authoritative Certification, Laying a Foundation for Market Popularization

CATARC Information Technology (Tianjin) Co., Ltd. has issued a formal verification certificate (certificate number: CAJSYX-XKZH2026-003805) for the LMX battery system, confirming that the product has fully met the technical requirements of extreme environment operation. This authoritative certification has laid a solid foundation for the subsequent market popularization of the LMX battery and its matching with more commercial vehicle models.

The cooperation between EVE Energy and Foton Motor has achieved a perfect combination of battery technology and vehicle manufacturing, and the successful verification is a joint achievement of the two enterprises in the field of new energy commercial vehicle technology research and development. It is expected that with the application of LMX battery system in more commercial vehicle models, the new energy commercial vehicle industry will break the regional operation restriction and realize the all-region coverage of cold and hot regions.

At present, the new energy commercial vehicle market is developing towards the direction of full-scenario adaptation, and the extreme low-temperature performance has become an important core competitiveness of products. The successful R & D and verification of EVE Energy's LMX open-source battery not only reflects the independent innovation capability of domestic battery enterprises, but also provides a strong impetus for the transformation and upgrading of the new energy commercial vehicle industry, and injects new vitality into the development of the green logistics industry.
