The CIC-EV (Beijing) is a national electric vehicle technology innovation, talent training, and technology incubation base in China. This center has more than 90 sets of experimental test platforms for advanced researches on full-size vehicle, driving and transmission, engine, battery, motor, smart vehicle infrastructure, electricity grid and so on. It should be highlighted that the center has the most advanced development and test platform for electric vehicle power driving system in China. This platform can provide the following types of experiments for three typical driving systems of electric vehicles (pure electricity, hybrid power, and fuel cell):
① Simulating the real-road driving loading performance;
② Investigating the control strategies of single-motor/dual-motor driving system;
③ Conducting control strategy experiments of engine-generator unit;
④ Assessing the integrated cooling system;
⑤ Testing the fuel cell stack characteristics;
⑥ Matching, calibrating and testing the fuel cell driving system;
⑦Performing electromagnetic compatibility and electrical properties experiments of electric/electronic components of vehicles.
Additionally, it also has a big-data center for electric vehicles, which could be able to real-time monitor the electric bus, electric sanitation vehicle, electric taxi, battery state, vehicle state and geographical positions of electric vehicles in Beijing.

The typical testing equipment in this center is described in detail as follows:
1) Development and Test Platform of Electric Vehicle Power Driving System
This platform as shown in Fig. 3.8 has the most complete functions in the field of electric vehicle power driving system in China. The typical experimental equipment includes:
①Comprehensive test bench of power transmission system;
② Mechanical and electrical matching optimization simulation system;
③ Environmental adaptability test bench of power driving system;
④ ISG motor and small motor test system;
⑤ Dual-motor driving test system of pure electricity vehicle;
⑥ Dual-motor coupling transmission test bench;
⑦ Fuel cell power system test bench.

2) Operation Service and Management Center for Electric Vehicles
This center is the largest operation service and management platform for electric vehicles in China, as shown in Fig. 3.9, which is capable of continuously collecting and storing the real-time monitoring information for vehicles such as electric buses, electric sanitation vehicles, electric taxis and electric cars. The collected information is mainly focused on battery states, vehicle status, and locations, etc. Communications between the platform and customers can be realized via short messages or telephone calls, etc. Monitoring data can be also directly forwarded to the relevant manufactures, user units, and other responsible units to secure the quick interaction between the fault information and emergency response. Presently, the platform holds 100 electric vehicles’ monitoring tasks every day, providing the interactive interfaces between companies and this center. Data information is monitored every 10 seconds, and directly forwarded to users. Based on the big data of this platform, it can be easily used for battery state-of-health (SOH) analysis, remaining energy and mileage estimation, charge station distribution planning, and it will be also gradually applied in passenger car leasing/charging/planning service.
