Transportation

From shipping to railway, and then to the airplane, human never stops pursuing the “speed” in the past century. How to travel faster, safer and more efficiently has always been a tough puzzle bothering the humankind. The application of superconducting technology can not only change the future traveling means and increase the traveling speed substantially, but also make the future traffic and transportation much more efficient and energy-saving.

Superconducting Magnetic Levitation Train

1. Brief Introduction

Ever since Elon Musk released the plan about Hyperloop vacuum tube train in 2013, the concept of “rapid transit” has attracted more and more attention. In 2014, the low-temperature superconducting high-speed maglev line from Tokyo to Osaka has already been constructed, and created a world record of 603 km/h in the test rail. Superconducting magnetic levitation train is a new land transport means which mainly suspends the train in the air by taking advantage of the electromagnetic attraction or repulsive force generated by the electro-magnetic induction, and drives the train with guiding and linear motor. Superconducting maglev train mainly consists of three parts, including the suspension system, propelling system and guidance system. 

Currently, countries including Germany, Brazil and China are now carrying out studies on the high-temperature superconducting maglev toroid. Different from the liquid helium cooling (-269℃) of the low-temperature superconducting maglev, high-temperature superconducting maglev adopts the liquid nitrogen cooling (-196℃), which improves the working temperature, and the speed in the vacuum tube can exceed 1500km/h. 

2. Values for Clients

 ⊙ Faster speed (over 600 km/h, vacuum tube can realize supersonic driving)

 ⊙ Green and energy-saving (its energy consumption per kilometer can be reduced by more than 70% compared with the high-speed rail, and several tenths of that of the airplane)

 ⊙ High safety, convenient rail construction (the suspension distance is as high as 250px, ten times of the maglev line in Shanghai)

 ⊙ Huge load (superconducting magnet has a higher magnetic field and greater traction than the conductive magnet)


Superconducting Motor (Electric Bus)

1. Brief Introduction

The application of superconducting motor in ship power is now being practical. It is estimated that there are also demands in the land transport field, and it would be firstly applied in service vehicles like buses. Furthermore, it is predicted that refrigerating machine will not be installed for service vehicles for the moment, and instead, liquid nitrogen for cooling will be equipped. After the refrigerating machine is improved, a small refrigerating machine would be installed for further enhancing the convenience and motive flexibility. In addition, superconducting motor would be a perfect match of the hydrogen fuel cell car equipped with liquid hydrogen. The replacement of liquid nitrogen with liquid hydrogen can further reduce the motor temperature and increase the current. 

2. Values for Clients

 ⊙ Compared with hybrid cars and common motors, the carbon dioxide emission of superconducting motor will be reduced by 25% and 13% respectively

 ⊙ The acceleration performance of superconducting electric bus is not inferior to gasoline-driven vehicles, and it is also stable and quiet

 ⊙ Superconducting motor mainly makes use of the increasing current in resistance-free state, and it is much more energy-efficient than ordinary engines


 Superconducting Wireless Charging

1. Brief Introduction

Superconducting wireless charging is an efficient power transmission technology which mainly takes the superconducting coil as the transmitting coil and allows the loading equipment to receive power supply in non-contact means. Compared with the traditional power transmission mode, wireless charging is more convenient and safer. Currently, wireless power transmission has already been applied to weak current fields, such as the medical treatment, mobile electronic equipment, and so on. In the future, wireless power transmission technology might be applied to the strong current field, such as electric vehicles, for reducing the floor area, lowering the impact of charging on the power grid and improving the safety. Since the wireless power transmission efficiency relies on the resistance of the transmitting and receiving coil, the smaller the coil resistance is, the higher the transmission efficiency will be. Therefore, high-temperature superconducting material has a broad development prospect in the wireless charging field.

2. Values for Clients

 ⊙ No DC resistance, low AC loss, and high transmission efficiency.

 ⊙ Huge carrying capacity, improving the energy density substantially, so as to make the transmission system much more compact.

 ⊙ Convenient for the promotion and application of efficient and high-power wireless charging technology (electric motor), so as to make contributions for the energy conservation and emission reduction.
