AVL Ripple Emulator™
Ripple emulation solution for battery and fuel cell testing
Batteries are one of the key components in modern powertrain configurations, such as hybrid, pure electric and fuel cell powered vehicles. This is why OEMs need to thoroughly test their batteries before putting them into operation.
During battery tests, the emulated charge or discharge current on the testbed and the real signal measured in the vehicle are different. This is mostly due to the highly dynamic background noise (known as ‘ripple’) of the inverter. Depending on the noise level, the lifetime of the battery can be affected. To tackle this issue efficiently, we have designed the new AVL Ripple Emulator, a ripple emulation device for battery and fuel cell testing.
The AVL Solution
The AVL Ripple Emulator is fully compatible with any AVL E-STORAGE DC source and works with your existing battery testing equipment. Both solutions, the Ripple Emulator and the AVL E-STORAGE BTE™ seamlessly integrate into the AVL tool landscape for an even more effective and automated test setup.
The AVL E-STORAGE BTE DC source features an internal ripple emulator that operates up to 2 kHz. Additionally, the AVL Ripple Emulator has been designed to add AC currents with frequencies up to 30 kHz to an existing DC bus. When working together, these two devices form an outstanding solution that can control the ripple directly at the unit-under-test. You can also use them as a broadband and powerful signal source for measurements of complex impedances.
- Accuracy: Innovative coupling network
- Performance: Best in class current frequency and amplitude directly at the unit- under-test
- Flexibility: Mobile design for higher device utilization
