The design and application of automobiles is one of the most challenging engineering topics in the world. Although automobiles continue to withstand dramatic temperature changes, continuous vibration and frequent human negligence, people still expect them to run flawlessly for many years. Requirements for new energy automobiles are higher: not only to reduce body weight, increase power-weight ratio, but also to shield high voltage power to protect the function of electronic devices in the car. Of course, the safety of drivers, technicians and first aid personnel must also be guaranteed. That's why car manufacturers rely so much on the safety and reliability provided by our contactors, sensors, harnesses, connectors and terminals.

The Ministry of Industry and Information has adjusted the scope of new energy vehicles to pure electric vehicles, plug-in hybrid vehicles and fuel cell electric vehicles, and strengthened the safety monitoring of new energy vehicle products, requiring real-time life cycle monitoring of the operation and safety status of all new energy vehicles that have been sold. Zhang Zhiyong, an automotive industry commentator, believes that attaching importance to quality will help the benign cycle of the new energy automotive market.

In order to fulfill the requirements of safety supervision for the promotion and application of new energy automobiles, the Ministry of Industry and Information Technology issued the Notice of the Ministry of Industry and Information Technology on Further Performing Safety Supervision for the Promotion and Application of New Energy Automobiles (Ministry of Industry and Information Technology [2016]377). The document requires each enterprise to establish a new energy automobile enterprise supervision platform and complete the docking work with the national monitoring platform. Since December 5, 2016, Beijing Polytechnic University has held "National Monitoring and Management Technical Seminar on New Energy Vehicles, Technical Joint Meetings", and officially launched the website of National Monitoring and Management Center for New Energy Vehicles (www.evsmc.org) on December 7, 2016 to receive applications for test reservations from vehicle enterprises. SREN has helped many car manufacturers complete data transmission tests for new declared models, vehicle terminals - enterprise platforms - National platforms. This is also considered to be an important measure to strengthen the safety supervision of the promotion and application of new energy automobiles, and to promote the healthy and sustainable development of the new energy automobile industry.

The time-sharing leasing mode of "depending on the happiness and disaster" of new energy automobiles must also receive the same attention. As the access threshold of new energy automobiles increases, the same problem must be faced based on the development of new energy--safety monitoring must be strengthened and real-time monitoring of automobiles must be carried out periodically.

• Track Location

  
  

  Support real-time vehicle positioning, tracking positioning and historical track playback. Vehicle track during tracking and playback can be displayed intuitively in the monitoring interface, which makes it easy for users to grasp the running status of the vehicle in time.

  
  

• Track Playback

  
  

  Support real-time vehicle failure alarm, conditional alarm, sound prompt failure mode, and support settings to send failure information mail to management users. Provides queries and statistics of historical failures.

  
  

• Statistical Analysis of Parameters

  
  

  Supports users to make statistical analysis on vehicle parts information (batteries, motors, etc.), operation information (speed, mileage, etc.), fault information, etc. The statistical results are displayed in lists, column charts, pie charts, line charts, etc.

  
  

• Driving Behavior Analysis

  
  

  By using the methods of bicycle analysis, multi-vehicle analysis and report analysis, the distribution map of driving behavior is supported, and the comparison between bad driving behavior and power consumption, summary comparison, speed distribution statistics, etc. can be achieved.

  
  

• Vehicle Working Condition Analysis

  
  

  The multi-parameter distribution is used to describe the running state of the vehicle, to characterize the changing range and law of each parameter, and to provide basic data for users to evaluate the rational use of the vehicle, whether the vehicle performance and structure can meet the requirements of use.

  
  

• Battery Parameter Analysis

  
  

  [Time Curve] The time curves of SOC mean, terminal voltage, maximum operating temperature of battery pack, mean operating temperature of battery pack, minimum voltage of BM single battery, maximum voltage of BM single battery, etc. can be achieved to help users observe the overall situation of battery operation.

  
  

• Charge and Consumption Monitoring

  
  

  Statistical requirements are automatically output through reports such as charging and discharging cost, cost consumption comparison among vehicles in fleet, relationship between driving behavior and 100-kilometer energy consumption, relationship between vehicle self-evaluation and 100-kilometer energy consumption.

  
  

• System Management

  
  

  With functions such as vehicle management, user management, role rights management, etc., through the establishment of fleet database, including vehicle coding information, driver information, operation information, etc., combined with vehicle instructions setup function, line planning function, to achieve emergency services such as vehicle scheduling, vehicle rescue and so on.
