DC LoadsSatisfy your Battery Test Requirements such as charge rate, discharge rate, state of charge (SOC), and state of health (SOH), and depth of discharge (DoD) with accuracy in measuring voltage, current, temperature and power both statically and dynamically.

DC Impedance Measurement For Battery Cell

The battery pack for electric vehicles requires the battery cells be paralleled for large current use. An important parameter is the impedance consistency of the battery cell since battery life may be affected if the impedance is not consistent. The DC impedance test solution offered by Chroma sets the discharge current change (ΔI) and measures the voltage change (ΔV), and then calculates the battery’s internal resistance using ΔV/ΔI as shown in the figure below.

LED Power Driver ATSThe Chroma 8491 Automated Test System is equipped with optimized standard test items for LED driver testing (lighting & TV backlight). The user is only required to define the test conditions and specifications for the standard test items to perform the test.

The optimized test items cover 6 types of power supply test requirements. “Output Performances” verifies the output characteristics of the UUT. “Input Characteristics” check the UUT input parameters. “Regulations” test the stability of UUT under varying line-in and loading changes. “Timing & Transient” test the timing and transient states during protection. “Protection Tests” trigger and test the protection circuit, the “Special Tests” provide means to test the most sophisticated UUT’s when unique test routines are needed.
