Engineering - EV power system- VIDO new business opportunity

Green Transportation

We focus on EV power system (hybrid DHT and flat wire motors), as an independent third-party supplier specializing in the power transmission system of new energy hybrid vehicles. HEV uses a gas engine and motor together without plug-in charging, relying purely on self-generated energy for high fuel efficiency. PHEV combines plug-in electric power for daily short-distance driving with a traditional combustion engine to handle long-distance road trips. REEV driven purely by electric motors, utilizing an onboard gas engine solely as a generator to charge the battery pack.

Hydrogen EV uses compressed hydrogen gas in a fuel cell stack to generate electricity onboard, emitting only pure water vapor.

More than 5,000t of shield machine

CN’s longest undersea tunnel.

On the bank of the Yellow Sea, in the Qingdao Port Terminal of Shandong Port, the shield excavation work of the main line tunnel of the southern line of the Jiaozhou Bay Second Tunnel is in progress in an orderly manner. After completion, it will be the longest undersea road tunnel in my country.. It is reported that the Jiaozhou Bay Second Tunnel is a main line tunnel plus an intermediate service tunnel. The tunnel is 14.37 kilometers long and the sea section is 9.95 kilometers long.. The tunnel has the function of a cross-sea passage for passenger and freight vehicles. Please follow the reporter's lens to visit the construction site of this super project.

China Built the World’s Largest Underwater Tunnel in Just 110 Days Massive Scale: The cutterhead has a diameter of 57.4 feet (17.5 meters)—roughly five stories tall. High Power: Equipped with over 7,500 horsepower and extreme torque to dig through dense riverbeds. Record Pace: Averaged 52 to 59 feet of daily progress, completing the 2-mile underwater section in 110 days. Waterproofing: Engineered to handle up to 7.5 bars of intense groundwater pressure. Prefabricated Rings: Workers assembled heavy-duty concrete rings seamlessly behind the machine on a continuous 24/7 schedule.

The Jinan Huanggang tunnel will feature six lanes of travel in both directions in a double-decker configuration, with a 60 km/h (37 mph) speed limit.
