Neware 500V200A EV Battery Testing System Automotive Battery Test Equipment
EV / PHEV / HEV Battery Testing System
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 .
Battery researchers and scientists , battery manufactures , importers and exporters , you can always choose the most appropriate Neware battery testers for battery quality check , battery performance tests , battery material research , and battery mass production lines .
Technical characteristics
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 .
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 .
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 .
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 .
