The development of thrusters with greater thrust and specific impulse was made possible by advancements in power supply, materials, and computer control systems.
The usefulness and efficiency of these propulsion systems have been demonstrated by prominent missions like NASA's Dawn spacecraft, which used ion propulsion to explore the asteroid belt, and the Mars Science Laboratory, which used a Hall-effect thruster to change course during its journey to Mars. 4.

In the process of long-term continuous charging, to verify material life and stability of charging coupler, and other characteristics, it must test its internal heat generating components and the temperature-rise components.
When the current is too large or the temperature exceeds the alarm limit high front panel is lit red light charging interface material while the system beeps.
The test system has a strong anti-interference ability and stable work characteristics conducive improve staff operating flexibility, and analyze historical data, to further protect the power system the quality of the network of key equipment Acknowledgements This work was supported by the High Technology Research and Development Program (863 Program) of China (No. 2011AA11A279), the Science and Technology Project of National Energy Administration (No.NY20110702-1), and the Technology Project of State Grid Corporation of China in 2013-2014 (Project Name is Study of Testing and Detection Technology for Electric Vehicle Charging/Battery Swap Infrastructure).
