# Lifetime Tester & Lifetime Simulation

Category: Test Systems · Product page: https://irs.systems/en/products/test-systems/lifetime-tester

Precise lifetime simulation with IRS lifetime testers: secure the durability of your components for e-mobility and powertrain through individual long-term tests and reliable load analyses under real conditions.

In lifetime simulation, several devices under test are usually tested in parallel in continuous operation. Very often, the assemblies are exposed to different temperatures (e.g. from -40 to +120 degrees Celsius) in climatic chambers during the tests. What matters most in these validation tests is that the measured values are recorded continuously and reliably over days and weeks. The data is evaluated, analyzed and documented by the operator.

Over the years, we have developed an optimal system with our own hardware components for these requirements.

We have been supplying systems for electromobility for several years. The high voltage range of up to 1000 volts and currents of several hundred amperes gave rise to further requirements.

While a control unit for comfort electronics, for example, can still be tested with very simple substitute loads or even original loads, this is no longer possible when testing inverters – the power electronics between battery and electric motor.

To simulate the electric motor, we can offer a patented electric machine emulator. It is designed specifically for lifetime testing, which has a very positive effect on our customers' investment volume, especially in this complex test environment.

## Requirements we meet

- Safe, failure-free operation of the test system over days and weeks
- Hardware and software designed for parallel testing
- Hardware and software that can capture even very fast signals in real time
- Software that allows test plans to be duplicated across multiple test stations
- Parameterizable data acquisition
- Handling of very large amounts of data with customized evaluation software
- Clear visualization of all running tests
- Control of the temperature chambers

## Remote maintenance option

Electronic control units for automotive applications require comprehensive validation to ensure that the device operates correctly for years under harsh environmental conditions. During validation, the inputs and outputs of the device under test must be stimulated and its operation continuously monitored.

IRS offers lifetime test systems that simulate all components of the vehicle. Our system communicates with the device under test and monitors all relevant signals for the development and validation process:

- Simulation of real load conditions
- Diagnostics via CAN (FD), LIN, FlexRay
- Independent operation of multiple DUTs in parallel
- Continuous monitoring of all signals
- Standardized hardware and software platform

## Applications

- E-mobility (inverters, battery chargers, battery management, power distribution)
- Powertrain (engine control units, traction control units)
- Body control modules, door control modules, lighting control
- Sensors, infotainment, etc.
