Functional Test And Measurement Of Fuel Cell Electric Drive System
Fuel cell-powered vehicles are a complement to pure battery electric-powered vehicles in electromobility. An electrochemical reactor is used to generate electrical energy that is available for the drive and other vehicle systems. The interaction of this reactor in the fuel cell stack with the other components in the powertrain is tested on test benches. In… Read more »
NVH And EV Powertrain Measurement Technologies Combine For A Powerful Solution
In addition to changes in current, voltage, power and even thermal measurements, electric powertrains also bring new challenges for acoustics: The HV electrical system and its sub-systems, new materials and the elimination of masking noise sources require a holistic view of acoustics and performance parameters. This application example shows how a harmonized measurement system from… Read more »
Webinar: Why Model Batteries?
A detailed understanding of battery technology and the underlying physics processes is necessary to design high-performance, durable, and safe batteries. Physics-based modeling is being used for building accurate simulations of batteries, incorporating different aspects through predefined physics-based interfaces, from detailed structures in a battery’s porous electrode to the battery pack scale, including thermal management systems….

How to measure EV current and voltage in confined spaces
Sponsored by CSM For tests drives of electric vehicles, high-frequency currents and voltages must be measured in the high-voltage vehicle electrical system. The installation options for the necessary measurement equipment can be very limited due to confined installation spaces. This example shows how currents and voltages can nevertheless be measured with high sampling rates, HV-safe… Read more »
Continental launches new sensor systems for EV battery protection
Parts supplier Continental will offer two new sensor systems for protecting EV batteries. The Current Sensor Module (CSM) is designed to protect batteries from over-currents by monitoring current and temperature. The ASIL D-compliant module also assists in calculating range by monitoring the current consumed and aids in finding mechanical malfunctions. The company says, “To support… Read more »
Measuring Electrical Power In Confined Vehicle Space
Whether early or late in the xEV development cycle, installing in-vehicle instrumentation for the accurate measurement of electrical power has been a challenge, until now. Accurate competitive vehicle analyses or production validation requires accessing cables’ inner conductors or busbars inside high-voltage components. CSM’s measurement technology has advanced to include new variants of it’s very successful… Read more »
