Battery Cyclers You Can Count On: Chroma Battery Testers Feature Seamless Fault Recovery Capabilities

Extended charge/discharge tests are an essential part of the design and validation of battery modules. These tests not only verify battery design and materials but also assess the performance, capacity, and thermal management of the entire module, estimate the battery’s lifespan, and ensure safe and stable operation. Battery charge/discharge testing typically requires hours to even months of testing time. Practical experience has shown us that operational errors, voltage anomalies, and failures in the channels of the battery cycling equipment during extended charge/discharge tests are among users’ primary concerns. When these issues arise, they can lead to test interruptions, which in turn may cause test failure and loss of test data. The device under test (DUT) must be reconfigured and retested, a process that not only consumes time but also significantly hampers product development efficiency.

To prevent the costly loss of important test data, Chroma 17020/17020E/17040 Series multi-channel regenerative battery test systems feature capabilities including fault recovery, per-channel test continuation, and seamless resumption of data recording. Using the built-in BatteryPro software, each channel can be individually paused when a test anomaly occurs. Once the issue is resolved, the user can choose to continue testing on the same node, start from the previous step, or select a new test recipe, thereby minimizing redundant test efforts.

If a test channel malfunctions during extended battery cycling, Chroma’s multi-channel charge/discharge equipment also supports manual channel switching and can seamlessly continue recording the test data. For example, in a 2500-hour cycle test, if a channel problem arises at the 1000-hour mark, the user can transfer the DUT to any other available channel on the same battery cycler and proceed with the test without interruption, and without compromising the integrity of the test data and reports. Besides alleviating user anxiety stemming from test interruptions, this approach also provides clear visibility into product development progress, helping to ensure a smooth and efficient product rollout.

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.
