We can see equipment's unit ID via LCD. What's more, 164 air socket is used to connect clamps and coin cells. CT-4000-mA equipment has already became the classic equipment, which is widely used in universities, laboratories and research institutes, and much much more.
Hanger: Fixing equipment on testing rack.
Switch: Start button.
Digital display: Display equipment number from 1 to 32.
NEWARE new cooling system is much safer and higher efficiency than before. Air inlet occupies the half of the left and right sides.
We can see the RS-485 interface and AC power supply on the back, which connect the control unit and equipment via Ethernet cable.
dQ/dV differential capacity curve: the peak on the curve indicates that there is a voltage plateau on the charge and discharge curve, and different peaks represent different electrochemical reactions.
Battery test steps need to be estimated for multiple conditions according to different operations during test applications; condition switches meet requirements for multi-exit programming types. "And""or" logic operation, "≥", "≤", "=" comparison; time duration "t", can meet control requirements for special tests. Each step supports 5 condition switches; support multi-exits, go to any steps, achieve more flexible process control.
Supports recording settings for voltage, current and time;
3 segment recording conditions can be set for each step;
each segment can be set: ∆T, ∆V and ∆I.
The unit of Q is Coulomb, 1 Coulomb = 1A * 1s = 1As; 1Ah = 3600 As(Amp Second); Work voltage U = Charge upper limited voltage - Discharge bottom limited voltage; working voltage can be set and the EDLC coulomb could be calculated automatically by the software.
Support DBC files import/ edit/ export. Different battery pack protocols just needs modifying DBC protocol file's code without upgrade the program, so that it can realize communication. The system is flexible and practical.
The constant current and constant voltage are integrated into a work step. After the constant current charged / discharged to the specified voltage, it is seamlessly switched to the constant voltage mode to supply the power of the battery pack. The switching process is smooth without spikes.
