Simulation - Because of high dynamic response speed , it supports the profile dynamic simulation , such as DCIR , HPPC , NEDC , FUDC , and other tests .

CAN Bus Decoder

To handle data exchange with the BMS installed on battery module or pack , Neware 6000 is also a CANBUS decoder with decode the signals from BMS . And these valuable data could be applied for further computing like used as stopping or protection conditions .

You can config which frame of CANBus data is for what use manually . Data also can be easily processed with the DBC file imported .

Simulation - the Way You Look into Reality

You know battery capacity at at constant current , or power , or load . But the reality is that no the energy is drawn by a constant variable . Your capacity or energy tested under constant conditions can only be a general one , and the cycle life tested such regime can also be largely deviated from reality . To have a better master of reality, simulation is introduced . GSM pulse is of such kind for phone batteries . for EV batteries , Drive Cycle Simulation is used .

Driving Cycle Simulation

Driving cycles are used to simulate car fuel economy at different operating conditions . There are many driving schedules or driving cycles that are issued by various agencies or institutes. To simulate EV , you need to convert the speed output into the power consumption or regeneration of the energy storage device installed on the vehicle .

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 .
