The milestone project opens up a new path for heavy-load highway freight. Sany designed, developed and manufactured the vehicles as well as the core systems, owning full intellectual property rights.
The demonstration road is two-way and two-lane with seven-metre road width. It uses 53 pillars and one box-type substation to support the 1.8-kilometre contact grid. The electrified highway provides a wide range of road condition scenarios for testing vehicle performance.
With an overhead contact network similar to rail transit, the electrified highway is directly powered by the grid above to achieve charging while driving. Compared to pure electric heavy trucks that run on batteries, the new system can prevent low temperature effects while increasing energy efficiency by six per cent.
