Case Study Highlights
- NI’s open, software-connected ecosystem enabled CATARC to develop a scalable battery-in-the-loop (BIL) to meet trends of battery test.
- A BIL system supports abundant test scenarios and boundary conditions. They combine the scene/road/vehicle model, reflecting the real conditions.
The Challenge
The traditional signal-level HIL test has been well established at the level of BMS functional strategy verification, but the battery pack performance verification capability is seriously insufficient. The road/field test of the real vehicle can obtain the most realistic battery pack performance, but the coverage of the test conditions is too narrow, and the requirements are too high.
The Solution
The battery-in-the-loop (BIL) test solution largely fills the test gap between HIL test and real-vehicle road/site test.
