Chroma’s 63600 Series DC Electronic Loads are designed for testing multi-output AC/DC power supplies, DC/DC converters, chargers, batteries, adapters, and power electronic components. They are excellent for research, development, production, and incoming inspection applications.
The 63600’s state of the art design uses DSP technology to simulate non-linear loads using an unique CZ operation mode allowing realistic loading behavior.
As electric vehicle (EV) technology advances, the on-board charger (OBC) has become a core module integrating power electronics and vehicle communications. Because architectures and protocols vary by OEM, test systems face varied and demanding requirements, especially in terms of real-time responsiveness and protocol handling.
Applying a sufficiently high test voltage and detecting electrical flashovers during the test can help to identify defective cells that pose a risk of future internal short circuits (due to partial punctures or perforations in the separator).
As electric vehicle technology advances into the fast charging era, lithium-ion batteries face increasingly severe challenges regarding safety and lifespan under high-rate charging. One of the most critical concerns is the phenomenon of lithium plating—when the charging current is too high or the temperature is too low, lithium-ions fails to intercalate effectively into the anode and instead deposit as metallic lithium on the surface of the graphite.
