New H Series 15kV programmable DC Power Supply provides a stable solar array simulation of Voc up to 1000V and Isc up to 25A. Incredibly fast transient response makes this DC supply an ideal tester for MPPT performance on PV inverter devices. Softpanels are a valuable option.
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.
At the CharIN Testival North America 2025, Chroma’s EV & EVSE charging test solution stood out among numerous international participants, winning third place in the test equipment category. This event is one of the world’s premier platforms for electric vehicle (EV) charging interoperability testing.
