Electric vehicle test system

for inverter

The inverter is a complex component, and its behavior and handling significantly influence the driving experience. To test and develop it independently from other components, a specialized test system is required. This system allows for testing the inverter early in the development phase – separate from the e-motor. An optimized testing environment, such as the AVL Inverter TS™, leads to an efficient verification process and reduced testing time compared to testing the Unit Under Test (UUT) in a real prototype vehicle. This approach accelerates the development cycle while enhancing the reliability and performance of the final product. The Heart and Brain of the Electric Vehicle The inverter is an intelligent mini-computer in electrified and electric vehicles. Together with battery and e-motor, they form the basis for the final driving experience. But, before all these components are tested together, every single one should be developed and validated on a dedicated test system. The frontloading of tests leads to shortened integration tests and therefore shorter time to market. The inverter controls and monitors all driving conditions and the vehicle’s safety-critical functionalities. Power electronics, in combination with a high level of signal complexity, require an appropriate test methodology and the use of adequate testing equipment.
