FAQ
Q1: What does 'Four-Quadrant' or 'Bi-directional' operation mean?
A: It means the supply can provide positive voltage/current (source, quadrant I) to charge a battery AND absorb power by providing negative current at a positive voltage (sink, quadrant IV) to discharge it, regenerating energy back to the AC line. This eliminates the need for a separate, wasteful dummy load.
Q2: Can it simulate real-world driving profiles for EV battery testing?
A: Yes. When paired with our test software, it can import or create dynamic power profiles that replicate real driving cycles (e.g., WLTP, UDDS), applying them precisely to the battery under test.
Q3: How is this different from using a standard DC supply and a separate electronic load?
A: This integrated solution is more precise, compact, and efficient. It eliminates synchronization issues between separate devices and recovers energy during discharge, which a standard resistive load wastes as heat.
Q4: Can it test battery packs with a Battery Management System (BMS)?
A: Absolutely. Its CAN and digital I/O interfaces allow it to communicate directly with a BMS for functional testing, to trigger safety events, or to log BMS data synchronized with its own high-precision electrical measurements.
Q5: What is required to parallel multiple units for higher power?
A: It requires units with the parallel option enabled, a proper cabling kit, and configuration via the software. Our technical team can provide full support for system sizing and integration.
