Battery Pack Power HIL Testbed

Chroma 8610 Battery Pack Power HIL Testbed can both test functions on the traditional signal-level basis and verify actual power behavior, more completely covering the test range of EV high-power components. Chroma 8610 highly supports the validation requirements at the right side of the vehicle’s standard V-model development process, from the integration of battery pack components to system-level functions; encompassing battery packs, battery modules, battery management systems, cooling/heating systems and other components. The testbed can implement various composite and simulated vehicle scenarios in advance before entering real vehicle testing. Users can so discover and correct problems early to reduce development costs and improve test efficiency.

In order to cover the complex behaviors of the real vehicle’s operation, many car manufacturers and their supplies have started to adhere to ISO 26262 as the functional safety standard in product development. ISO 26262 extends from the product system down to hardware and software, and stipulates the content of safety requirements: functional safety → technical safety → hardware safety → software safety. At any automotive safety integrity level (ASIL), HIL and fault injection tests are necessary to verify the accuracy of the vehicle safety mechanism and the effectiveness of the failure coverage.

The integrated fault injection unit performs arbitrary open and short fault tests for various control and communication signals of the device under test. Chroma 8610 can integrate dynamic discharge, insulation resistance change and static charging, and other vehicle behavior simulations, to simulate and verify the most important compound vehicle scenarios for real vehicle and composite operation conditions with the highest risk of failure. Greatly improve the fault injection test from the ISO 26262 process and obtain ASIL certification by performing more in-depth tests on battery packs without the need to test a real car.
