Maintenance of HV measurement technology – calibration and insulation testing
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:
- How do you prevent measurement bottlenecks when calibration of your measurement amplifiers is due?
- How can you save valuable resources such as time, money and maintain confidence?
- What additional benefits do you enjoy by having your measurement technology tested at your site?

Configure measurement chains quickly and reliably - Avoid expensive and time-consuming errors
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:
- Using standard names from signal databases
- TEDS as electrical data sheets
- Transferring calibration data from sensor databases
- Possibilities to split tasks and automate processes

Vector Smart Logger - The Intelligent Logging Solution for E-Mobility and ADAS Developments
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.

Use Cases
VIO System - Centralized measuring system with the additional something
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.
Current and Voltage
Current measurement in e-mobility
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.
- Which currents must be measured at which points in the HV electrical system?
- What requirements are placed on the measurement technology?

Temperature measurement in e-mobility
Temperatures play a major role in the performance and safety of vehicles with electric, fuel cell or hybrid drive systems.

Thermal characterization of HV batteries
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.
