https://www.ti.com/ BATTERY MANAGEMENT SYSTEM 11 www.power-mag.com Issue 4 2025 Power Electronics Europe BMS testing, a signal-level approach provides benefits in terms of price efficiency and a more compact test system footprint. Since signal-level testing doesn’t require any real cell voltages, the test systems are less complex and require fewer safety installations. Signal-level testing also offers design flexibility. Testing system functions early allows designers to focus on optimization even before the real battery or battery pack monitoring hardware (like the CSU) becomes available. And beyond just simulating the cell controllers, the dSPACE solution can also emulate communication with the main BMS controller, the vehicle electronic control unit, real-time test computers, or vehicle hardware. Typical use cases of the dSPACE cell controller virtualization solution include running integration tests on the main BMS controller to validate its communication with other vehicle control units, such as the e-motor controller (inverter) or the onboard charger in hybrid and electric vehicles. You can also test state-of-charge and state-of-health algorithms for fault detection and reaction, and conduct integration tests on a system or on a full vehicle hardware-in-the-loop simulator. These emulators are based on powerful field-programmable gate arrays (as shown in Figure 3) and are able to meet demanding timing requirements. They support a wide range of communication protocols, for fast, safe and isolated communication. This enables more flexible testing capabilities, such as connecting the emulated battery pack to the battery management unit in a hybrid emulated/real hardware environment. Conclusion After two decades of automotive BMS innovations, it’s exciting to see corresponding advancement in emulation solutions. By emulating TI battery management ICs, the dSPACE cell controller virtualization solution helps facilitate system development earlier in the design process. An expedited process enables software to progress before hardware is available and tests real-life or extreme conditions to help enhance system safety and reliability.
