BANGKOK, March 11, 2026 /PRNewswire/ -- U Power Limited (Nasdaq: UCAR) ("U Power" or the "Company"), a provider of AI-integrated solutions for next-generation energy grids and intelligent transportation systems, today announced that it has successfully completed comprehensive operational testing and full-stack integration of the battery-swapping system of heavy-duty truck prototype vehicles designed to be deployed in Thailand.

This milestone marks a key step forward in U Power's collaboration with Whale Logistics (Thailand) Co., Ltd. ("Whale Logistics"), a strategic partner, to deploy 1,000 battery-swapping heavy-duty trucks in Thailand. The strategic partnership, formalized in December 2025, paves the way for the production and delivery of the first batch of heavy truck tractors by May 2026.

The battery-swapping heavy-duty truck project was jointly developed by U Power, SAIC Hongyan Automotive Co., Ltd., a company focused on the development, manufacture, sales and services of heavy trucks, and UNEX EV, a new energy and technology company. The prototype vehicles underwent three months of full-condition road testing, during which the key systems were thoroughly evaluated. Following full-stack integration, all technical parameters met design specifications and aligned with Whale Logistics' requirements for electrified highway logistics transportation, positioning the prototypes for immediate transition to mass production.

As Thailand's inaugural and flagship battery-swapping heavy-duty truck project, the cooperation between U Power and Whale Logistics aims to accelerate the adoption of green and sustainable battery-swapping solutions in the country's road logistics sector. Supported by U Power's UOTTA^TM battery-swapping solution that enables battery swaps within minutes, operational efficiency of electric transport vehicles can match that of conventional fuel-powered trucks. At the same time, vehicle operators can avoid substantial investments in grid expansion and charging infrastructure while eliminating concerns about battery performance degradation. This model offers a greener and more cost-efficient, and replicable transportation solution for the highway logistics industry.

Johnny Lee, Founder and Chief Executive Officer of U Power Limited, stated: "Completing full-condition road testing of our pilot vehicles confirms the reliability and efficiency of the UOTTA battery-swapping model. Via the partnership with Whale Logistics, we are set to deploy 1,000 vehicles in Thailand to meet high-frequency logistics demand and boost operational efficiency. Thailand is a strategic market in U Power's global growth plan. By pioneering battery-swapping solutions for taxis and heavy-duty trucks, we are strengthening our leadership in Southeast Asia and driving low-carbon commercial transportation, while laying the foundation for expansion across the region.
