Low-voltage standards

Testing 12 V, 24 V and 48 V components

Low-voltage electrical systems play a central role in modern vehicles, supplying everything from electronic control units (ECUs) and sensors to infotainment and comfort functions. Key standards, such as ISO 16750-2, LV 124, and OEM-specific requirements, define the power input conditions these components must withstand and the behaviours they must demonstrate.

Although the nominal voltage may be relatively low, testing can require high continuous and dynamic currents, depending on the device under test and test configuration. Combined with fast voltage transients and demanding load profiles, these requirements place significant demands on the power and dynamic performance of the test system. As a result, even low-voltage test systems can reach power levels of tens of kilowatts.

Our modular low-voltage test systems enable you to:



• Reproduce complex voltage and current waveforms, fast transients and interruptions even under high-current conditions
• Maintain stable, precise and repeatable performance under demanding dynamic loads
• Scale power and current capacity for different components and test requirements
• Access extensive standards-based waveform libraries
• Combine waveform generation, measurement, data acquisition and reporting in an integrated test environment

High-voltage standards

Testing EV and PHEV components

High-voltage electrical systems are central to electric and plug-in hybrid vehicles, supplying components such as traction inverters, onboard chargers, DC/DC converters, electric compressors and high-voltage heaters. Standards and manufacturer requirements such as LV 123, VW 80300 and ISO 21498-2 define the electrical conditions and disturbances that must be reproduced within modern high-voltage architectures. Bolab supports high-voltage testing for these and related requirements.

High-voltage components operate at significantly greater voltage and power levels than conventional low-voltage devices, with ratings ranging from tens to hundreds of kilowatts. Testing requires precise control of voltage variations, ripple, transients and other dynamic electrical conditions while maintaining stable operation at high power.

Our scalable high-voltage test systems enable you to:



• Reproduce demanding EV and PHEV power input conditions at more than 1,500 V, 2,000 A and 1,000 kW
• Configure system power and performance around your application and device under test
• Generate complex standards-based and custom waveforms
• Adapt your test capability as OEM specifications and industry standards evolve
• Protect people, equipment and the device under test with integrated safety and interlock functions
