Description

New Energy Vehicle Motor Dynamometer (EC80-10)

EC80-10 is a new energy automotive parts test system with independent intellectual property rights and complete functions, which is another dedication to the EMC industry after CHANGEN successfully designed and installed the first set of nationally produced EMC test dynamometers in China. Each indicator of the system is higher than or equal to similar indicator of the similar imported equipment.
The three major parts of new energy automobile battery, electric drive and motor can be tested and evaluated on EC8-10.
All system components of EC80-10 are designed domestically, including battery simulator system, dynamometer motor, dynamometer motor drive system, test bench and other main system components which are produced and manufactured by domestic manufacturers. Short maintenance cycle, low cost and easy to communicate.
Some of the system indicators can be customized according to customer needs.
