Measurement Technology The Vector CSM E-Mobility Measurement System Current and Voltage Power and Efficiency Temperature Durability Data Logging NVH
The use of measurement technology in the high-voltage environment brings with it a number of new regulations and requirements that must be observed. First and foremost is the safety of the operator, which places new demands on the measurement technology.
An essential aspect in long-term utilization of measurement technology is the regular calibration of the measurement amplifiers. In the case of high-voltage safe measurement technology, not only should the modules be part of a preventative maintenance and calibration schedule like other equipment, the high-voltage insulation test, which is urgently required according to EN 61010, must also carried out on a regular basis.
In this webinar, we will show you our solutions for calibration and HV insulation testing and deal with the following topics:
Increasing demands of developers on measurement tasks mean that the number of measurement channels is constantly growing and test setups are becoming more and more complex. Measurement chains with significantly more than 50 channels are no longer uncommon - and the error-free input of signal names and scaling factors can quickly become a challenge. For perfect measurement results, however, all designations must be correct. Typing errors and transposed numbers, made for example under time pressure, can render entire measurements unusable.
In this episode of CSM Xplained, we show how you can integrate existing data in just a few steps when configuring measurement chains and thus avoid costly errors.
This includes:
Benchmarking plays a major role in vehicle development. Vehicle manufacturers want to understand how competitors solve problems - service providers want to offer comprehensive and objective data sets that enable precisely these comparisons. To obtain this data and the resulting insights, robust and flexible measurement systems are required that can be used, for example, to implement a large number of measurement points for a wide range of measured variables in production vehicles in confined spaces.
In this web seminar, we will show you in a compact 25 minutes:
Global competition, time pressure due to shortened development cycles and rising costs in the areas of materials, energy and staff - these are the challenges currently facing the automotive industry. To overcome them, a flexible and cost-efficient measurement system is needed that provides vehicle manufacturers, suppliers and engineering service providers with a tool for vehicle development of electric and hybrid vehicles of all kinds.
In this web seminar you will learn:
vMDM (Vector Measurement Data Management) is the cloud solution for efficiently managing large amounts of data from development, test benches and drive tests.
A comprehensive function library, precise algorithms for calculating characteristic variables, and modern cloud technologies enable fast and meaningful analysis of the variables in electrical components, drives, and vehicle electrical systems that are precisely and time-synchronously recorded using CSM measurement technology.
Fuel cell drives require an extensive amount of testing and measurement during the development phase. This is because the combination of electrochemical components and power electronics places special requirements on the measurement technology.
In this webinar, we will take a close look at measurements on fuel cells and address the following questions:
For the comprehensive analysis and testing of electric vehicles, physical parameters from numerous sources (HV and low-voltage environment) must be acquired and analyzed. A precise evaluation of the data is only possible through the synchronous acquisition of the data. In addition, the design of such a measurement system should be conceivably simple and precisely tailored to the measurement task.
When developing vehicle systems, engineers from development and validation often work on the same test vehicle. However, their working methods differ fundamentally. In development, the focus is on ad-hoc investigations with an interactive character. In validation on the other hand, preconfigured measurement jobs are recorded autonomously over several test drives. Up to now, different tools have been used: a computer-based measurement system and a specialized fleet logger. In practice, this always means set-up time - i.e. reconnecting when changing the mode of operation - and also doubled maintenance effort for the configurations.
Vector Smart Logger overcome these hurdles and offer a system that can be operated both interactively and autonomously. This significantly reduces setup time and configuration effort.
Beyond that, you benefit from a significantly higher range of functions compared to classic fleet loggers. Signals from vehicle ECUs and buses, radar, LIDAR, cameras, analog measurement technology as well as online calculations, e.g. of the eMobilityAnalyzer, can be recorded synchronously. Complex system interactions can be investigated holistically.

Analog measuring systems can be classified into two groups: On the one hand, decentralized measuring systems that can be positioned in confined spaces and operated under demanding environmental conditions. On the other hand, centralized measuring systems, which are less robust and larger in comparison, but offer a higher number of measuring inputs and often lower costs per channel.
The new VIO system from Vector Informatik is such a centralized measuring system. Thanks to its measurement card-based design, the measurement system can be easily scaled. By integrating network interface cards, the measurement task can be extended from purely measuring analog measurement values to bus monitoring and adjustment.
Currents must be measured at many points in the HV electrical system of modern electric vehicles: Be it to analyze charging and consumption processes or to verify protective measures against shield currents. The precise investigation of high-frequency current components requires a wide bandwidth in measurement, and instrumentation in particular can present users with challenges.
Technological development in the field of on-board charger (OBCs) is currently experiencing a push toward higher integration along with other power electronics of electric vehicles. On-board charger in vehicles have to cope with different grid standards and charging networks worldwide. AC charging verification and OBC testing is therefore a particularly critical step for vehicle series release. The correlation and synchronization of measurement technology integrated in the vehicle with measurements outside the vehicle is also becoming increasingly important.
In this web seminar you will learn:
DC and AC voltages in the HV environment are characterized by peaks and dips as well as superpositions and have a significant influence on the interaction of all components. To ensure proper operation of the entire system, regulations set limits and must be verified.
The testing of electric drive systems requires a wide range of measurements and analyses of electrical power in the most varied degrees of detail. Depending on the application, extensive analyses including efficiency determinations may be necessary for the optimization of e-axles - while other contexts, such as the determination of consumption values, tend to benefit from independently performed power measurements.
Key points of the web seminar:
Temperatures play a major role in the performance and safety of vehicles with electric, fuel cell or hybrid drive systems. If the temperatures in components such as the HV battery deviate significantly from their ideal range, performance losses, accelerated wear or even total failure are the result. Accordingly, temperatures must be measured intensively at many points.
The performance, operational reliability, fast-charging capability and aging of HV batteries depend crucially on comprehensive and good thermal management. For this, it is important to know the temperature profiles within the battery that occur in different operating states in as much detail as possible. Battery management systems (BMS) have the task of operating the battery within its "comfort temperature".
The development of high-performance thermal management systems requires extensive thermal analyses.
Accelerations must also be measured safely and precisely in high-voltage environments. For example, HV batteries are used as load-bearing elements in the vehicle frame. Accordingly, extensive investigations of fatigue strength are required on high-voltage components, but also within the HV environment.

Testing of durability poses great challenges for the measurement equipment to be used, especially in the high-voltage environment. For example, the so-called "swelling" is to be investigated on HV battery cells. For this purpose, strain gauges are primarily used whose output signals, some of which are very small, must be recorded precisely, reliably and safely at a high voltage potential.

The reliable detection of strains and temperatures in the e-mobility environment poses a major challenge - the very small amplitudes of the measurement signals are many orders of magnitude below those of the system voltages of several hundred volts used. And the wireless transmission of these measured variables is also massively hampered by the enormous electromagnetic interference generated by respective components of electric vehicles themselves.
In this episode of CSM Xplained, we present exciting solutions for the reliable and precise measurement of strain gages and temperatures. Find out more about high-voltage safe, wired and also innovative wireless solutions for strain gages and temperatures - this time in interview format with telemetry expert Gerhard Spitz from AXON Systems.

The use of classic measurement computers in supervised test driving is problematic in many respects. Staff supervision costs, occupant safety during extreme driving maneuvers and operability under driving conditions are just some of the disadvantages of using laptops and other display-supported end devices. In this episode of CSM Xplained, we show how the measurement computer can be dispensed with in many applications and replaced by a robust and connected data logger.

The electrification of mobility in particular has intensified competition among vehicle manufacturers. At the same time, the amount of data generated in modern vehicles is exploding as a result of progressive digitization. Extensive recording of fieldbus data, e.g. from control units by means of powerful data loggers, is becoming increasingly important.
To remain competitive, field tests and fleet tests must be as reliable and efficient as possible. For this purpose, worldwide data transmission of the recorded measurement data by means of modern wireless technologies is essential. In addition, it must be possible to manage large vehicle fleets easily and conveniently.
Learn how to meet these challenges in this issue of CSM Xplained.
When recording measurement data in fleet testing, the security of your data plays an essential role. An overall system that works reliably and at the same time protects data sources and recordings from unauthorized access, is required. In this episode of Xplained, we show you how this can be implemented with our system.
Key points of the web seminar:
The electrification of the vehicle powertrain poses major challenges for the interaction of the individual components. In order to optimize both - the acoustics and the performance of electric vehicles, high-voltage and NVH measurement data must be acquired synchronously.
In this web seminar we show the problem in the acoustics of electric vehicles and the solutions for eMobility and NVH analysis:
