Battery Charge/Discharge Test Software

Battery Charge/Discharge Testing SoftwareChroma has developed two software modules that integrate a DC power supply and an electronic load for battery pack testing. The Battery Charge/Discharge Testing Software programs the test sequence, loop and stop conditions. The measured voltage, current and power data is recorded in a file for future analysis. The Dynamic Current Waveform Simulation Software records to an Excel compatible file actual discharge current waveforms from the battery and instruct the electronic load to sink the same current. This is used to simulate real world applications and evaluate the battery pack in the lab.

How to Use RF Impedance Measurements to Ensure the Quality of Miniaturized Power Inductors

Most high-frequency and miniaturized power inductors are metal molding-type inductors. The magnetic metal powder surfaces are usually treated with an oxide layer to reduce eddy current losses at high frequencies, enhancing the usable frequency range and reducing losses and temperature rising. However, users typically cannot determine the particle size of the magnetic material and the integrity of the oxide layer after molding and sintering through visual inspection alone.

Leveraging Certificate Management Tools for Comprehensive EVSE Plug & Charge (PnC) Testing

Chroma’s PowerPro 5 software, part of its comprehensive EV test system solution, features a Certificate Management Tool that allows users to load specific certificate files (*.p12, *.pem). Using designated OEM agreements and contract certificates, the software automatically performs public/private key encryption and decryption during the test to achieve the handshake and payment processes required for ISO 15118 PnC testing.
