U Power has completed comprehensive operational testing and full-stack integration of the battery-swapping system for heavy-duty truck prototype vehicles it has designed for sale in Thailand.
The completion of testing marks a step forward in U Power’s collaboration with Thailand-based Whale Logistics to deploy 1,000 battery-swapping heavy-duty trucks in the country. The strategic partnership, which was 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, heavy truck supplier SAIC Hongyan Automotive and technology company UNEX EV.
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, enabling the companies to move to mass production.
Supported by U Power’s UOTTA battery-swapping solution, which enables battery swaps within minutes, electric trucks can match the operational efficiency of legacy fuel-powered trucks, the company said.
At the same time, vehicle operators can avoid substantial investments in grid expansion and charging infrastructure while eliminating concerns about battery performance degradation.
“Completing full-condition road testing of our pilot vehicles confirms the reliability and efficiency of the UOTTA battery-swapping model,” said Johnny Lee, founder and CEO of U Power. “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.”
