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 .
Want to use a battery tester for all kinds of purposes ? Wanna give it a shot with low risk ? BTS4000 is very possibly the correct choice for you to get to know Neware and her battery test products better . Till year 2017 , 90% new customers of Neware would choose BTS4000 as a starting point , it’s really the time-proven and reliable choice .
a . Modularization . Each module is 4 channels 120V50A . Expandable for 8 channels / 12 channels , etc . in one cabinet .
b . Parallelled . Up to 4 channels to be parallelled connection , can reach 200A in one module .
c . Regeneration . The regenerative function is included to greatly reduce power consumption during the discharge test.
d . Communication; Able to log parameters from BMS, Chamber, I/O signals as a condition for cut-off or protection during testing. Support CANbus, RS485 protocol, SMbus, I²C.
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’s fuel economy at different operating conditions. There are many driving schedules or driving cycles that are issued by various agencies or institutes. You can visit the EPA (U.S. Environment Protection Agency) website for more: https://www.epa.gov/emission-standards-reference-guide/all-epa-emission-standards. 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.
CAN Bus Decoder
To handle data exchange with the BMS installed on battery module or pack, Neware EVT 7000 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.
