Neware 200V300A Electric Vehicles Battery Test System Cycle Life Tester
CT - 4000 , based on Neware 4th generation testing system , entered into market in 2008 .
CT - 4000 supports some testings as follow , EV battery pulse charge / discharge , DCIR - Direct Current Internal Resistance , cycle life and rate .
CT-4000 mainly applies for institutions , colleges and universities and EV battery manufacturers .
1 . High efficiency and energy saving
With bidirectional DC / DC and DC / AC power units , the battery discharge energy can be efficiently fed back , the input of air conditioning and exhaust system can be reduced , and the production cost can be reduced .
2 . Fast response
DC / DC adopts single CPU control , reduces data communication time and dynamic conversion time less than 10 mS , which is superior to parallel power unit system .
3 . Excellent performance
The controller is designed with high - speed and high - precision sampling control chip, optical fiber driver and self - made driver board . It has strong anti - interference ability , system conversion efficiency more than 94 percent , grid - connected harmonics less than 3 percent , power factor more than 0.99 , charging and discharging accuracy less than 0.1 percent .
4 . Patent Heat Dissipation
The EBM centrifugal fan imported from Germany , the patented scheme of upper and lower air inlet and outlet heat dissipation , the efficient design of heat dissipation duct , good heat dissipation effect and low temperature rise of the device can effectively reduce dust and sand entering the cabinet and prolong the life of the product .
