Frequently asked questions
Battery test and emulation solutions help engineers evaluate EV batteries across levels from individual cells to complete packs. They support reproducible battery measurements, precise test sequence control, data management, characterization, and regenerative discharge capabilities that can feed energy back to the grid.
Electric vehicle supply equipment (EVSE) emulators are used to validate EV and charging-station behavior through real-time emulation of EV and EVSE interactions, helping teams test charging conformance and interoperability without needing multiple physical devices. Grid emulators provide programmable AC or DC power with bidirectional power flow, allowing them to act as a power source for EVSE emulation, an electronic load, a battery-pack replacement, or a way to feed energy back to the grid during EV emulation.
Automotive EV emulator solutions should support the charging standards, communication protocols, and conformance requirements relevant to the vehicle, charger, or power electronics system under test. This includes global AC and DC charging standards such as CCS, CHAdeMO, GB/T, and more, along with EV and EVSE communication needed for conformance and interoperability testing.
For advanced charging applications, support for bidirectional operation and vehicle-to-grid (V2G) capabilities is also important. A comprehensive solution should combine power emulation, communication and power analysis, synchronized measurement and decoding, and repeatable automation so engineers can validate charging behavior under controlled test conditions.
EV emulators are used to reproduce battery, charging, and power-electronics conditions in a controlled and repeatable test environment. Battery test solutions help evaluate cell, module, and pack performance, while charging test solutions emulate EV and EVSE behavior to validate safety, efficiency, conformance, and interoperability.
For high-power and grid-interaction testing, AC and DC grid emulators can source or sink energy, operate as an electronic load, replace a battery pack, and feed energy back to the grid. They also support hardware-in-the-loop (HIL) and power hardware-in-the-loop (PHIL) use cases for realistic testing of complex EV systems without requiring full vehicle prototypes.
Integration starts by matching the emulator’s voltage, current, power, bidirectional operation, charging-standard support, communication analysis, and software capabilities to the device under test and the required validation workflow. For charging systems, modular and scalable EV / EVSE test systems can support R&D through end-of-line manufacturing.
For larger battery test environments, lab and production operations software helps coordinate test sequences, manage lab resources, reduce test bench idle time, improve asset utilization, and maintain traceability from initial order to final report. This supports more consistent battery, charging, conformance, interoperability, and production-oriented test workflows.
