Service Feature: High Voltage EV Module Testing
As electric vehicles (EVs) become more advanced and widespread, the need for precise and reliable electric vehicle testing is more critical than ever. High-voltage components, especially battery systems, play a central role in EV reliability, performance, and compliance. In this article, we explore the importance of high-voltage EV testing and how Elite’s AMETEK PowerWave Test Systems deliver the advanced module testing capabilities needed to support today’s complex EV technologies.
What Components of an Electric Vehicle Are High Voltage?
Many of the systems that power electric vehicles operate at high voltage, typically anything above 60V DC. Examples of high-voltage components in electric vehicles that Elite provides module testing for include:
- Electric Motors and E-Axles
- Inverters and Chargers
- Battery Systems
- Battery Control Modules (BCM)
- Auxiliary Modules
Understanding what components of an electric vehicle are considered high voltage is essential for effective system design, compliance, and testing. These parts are not only integral to EV performance but also carry significant reliability risks if not properly tested.
How AMETEK PowerWave Supports Elite’s EV High-Voltage Testing Services
Elite’s two AMETEK PowerWave 250 Test Systems are high-power sources for applications where exceptional performance is required, such as Electric Vehicle testing. The PowerWave Test System is a Bidirectional Power Supply rated to supply 1500VDC or 1000A. It can be operated together (500 kW) or individually (250 kW) as needed for a variety of high-voltage electric vehicle testing applications. We also have an AMETEK Ripple NX Generator capable of 1000A (1000Vmax). This equipment allows us to test electric drive systems in motor and generator mode as well as charging and discharging of HV batteries.
