ISO 16750-2
Reproduce ISO 16750-2 electrical loads for 12 V and 24 V components
What is ISO 16750-2?
ISO 16750‑2 is an international standard that defines electrical load tests for electrical
and electronic systems and components used in road vehicles. It specifies the typical electrical stresses found in 12 V and 24 V automotive power systems and outlines how ECUs, sensors, actuators, and other modules should be tested under these conditions.
The standard covers a wide range of electrical conditions that components may experience during vehicle operation, including voltage fluctuations, supply interruptions, overvoltage, undervoltage, and dynamic transients.
By reproducing these conditions in a controlled test environment, engineering teams can evaluate whether components continue to operate, recover correctly or respond safely according to the criteria defined for each test.
What makes ISO 16750‑2 challenging?
Testing according to ISO 16750‑2 is demanding because it requires precise reproduction of complex and highly dynamic electrical events.
Long‑term overvoltage
Sustained high voltage stresses components thermally and electrically.
Jumpstart conditions
External starting can expose electronics to significantly elevated voltages.
Slow voltage decrease and increase
Simulates battery discharge, engine cranking, and controlled power‑up/down, testing reset behavior and power‑management robustness.
Transient overvoltage and undervoltage
Fast spikes and dips require test equipment with high speed and accuracy.
Superimposed alternating voltage
AC ripple from alternators or converters challenges filters and power‑supply circuits.
How Bolab meets these test requirements
We offer a complete, modular solution for the electrical load tests defined by ISO 16750-2. Our 4‑Quadrant Amplifier Systems, Fast Interrupt Switches, Switch Matrices, and programmable power supplies work together to reproduce all electrical load conditions with high precision and repeatability.
With switching times below 100 ns, bidirectional current control, high‑dynamic voltage profiles, and fully automated waveform generation, our systems address demanding tests such as transient events, voltage drops, jump‑start conditions, and complex supply variations.
By combining these capabilities with our WaveMaster software, we offer a turnkey platform that allows your team to execute ISO 16750‑2 tests reliably, efficiently, and in accordance with the standard.
Advanced capabilities for ISO 16750-2 testing
Our modular test systems combine the hardware and software capabilities needed to perform demanding ISO 16750-2 electrical load tests. Each capability helps your team reproduce real-world vehicle power conditions with precision and repeatability, ensuring reliable validation of automotive electrical and electronic components.
Integrated and modular by design
Waveform generation, power amplification, voltage and current monitoring are combined in a single architecture, while enabling incremental expansion from 2 kW up to 18 kW, resulting in a compact system that allows the test setup to scale with evolving power and application requirements.
Unmatched accuracy and repeatability
Ripple testing is one of the most demanding parts of ISO 16750-2. Bolab systems are designed for high‑dynamic superimposed alternating voltage tests across the full required frequency range. With high bandwidth and low output impedance, ripple waveforms remain stable even in resonance‑critical DUT conditions, enabling repeatable results.
Simple software for complex testing
WaveMaster centrally controls all Bolab test hardware, ensuring seamless system interaction during testing. It enables automated reference testing, adaptive voltage and current control, the generation of DUT-specific test profiles and real-time measurement. WaveMaster's vast waveform library covers ISO 16750-2 and is continually updated, enabling fast, accurate, and repeatable testing.
Mastering the complexity of ISO 16750-2
Bolab combines integrated impedance analysis with fully automated reference testing to determine DUT-specific limits with maximum accuracy. Adaptive voltage control and real-time current limiting ensure safe, precise execution under dynamic conditions. Instead of static profiles, individual test curves are generated for each DUT and executed via the WaveMaster software, allowing fully automated, reproducible, and standard-compliant testing.
