Get to Know BTS8000

BTS8000 is based on Neware 5th-generation testing system. It supports EV battery driving schedule tests, pulse charge and pulse discharge tests, Cycle life test, and charge and discharge tests with customer-defined rate.
One of the most outstanding features of BTS8000 is the driving schedules simulating, which allows the system to charge or discharge the battery pack by simulating the actual vehicle’s driving schedules in the laboratory. It supports all the DDS(Dynamometer Drive Schedules) from EPA, such as IM240(Inspection & Maintenance Driving Shedule), UDDS(EPA Urban Dynamometer Driving Schedule), FTP(EPA Federal Test Procedure), HWFET(EPA Highway Fuel Economy Test Driving Schedule), NYCC(New York City Cycle Driving Schedule), etc.
As the World-class driving schedules battery testing system, BTS8000 comes with great driving schedules simulating, wide range of applications, high-speed testing data acquisition, high accuracy and many other industry-proven characteristics, it’s your unmissable choice for driving schedules battery tests!

Driving Cycle Simulation in Neware BTS8000

Driving cycle is most used for dynamometer test on fuel economy at different conditions. There are many driving schedules or driving cycles issued by various agencies or institutes. They are basically a speed table as a function of time, and there may be road slope taken into account. You can check the EPA (U.S. Environment Protection Agency) website for more: For those simulations for EV, you need to convert these speed output into the power consumption or regeneration of the energy storage installed on the vehicle. 

1) Your driving cycle table should consist of a row of time, and another row of power or current. As conventional, positive stands for charge or regen, negative discharge. Your driving cycle file should also comply with this convention. 

2) Now, choose a BTS8000 type for this simulation test (BTS8000 responses fast, and benefited from the multi current ranges, it has a better current or power accuracy over the whole scale). Click to choose a SIM step type. 

Click File path will launch a dialogue as below. 

You can choose sections of the file to be performed. And assign units to the 2 columns of the value, choose power mode or current.  And also, you can use an integer as a multiplicator, this will multiply the column selected for power or current with the number you input.

3) Following graph goes the output performed by Neware BTS8000.
