Constant temperature equipment for automotive testing

In the automotive industry, temperature control is mainly found in test and inspection rigs, as well as material tests. All the components of an automobile are exposed to extremely high temperature fluctuations to ensure that they function correctly and reliably during subsequent use. This process of testing many different components in special test rigs makes an important contribution to increasing quality and reliability. The simulation of extreme environmental conditions across a wide range of different temperatures is an important part of the material tests. Climatic chambers are used to simulate ambient temperatures, while process thermostats control the temperature of the coolant to simulate cooling circuits in the vehicle. The heat flow in the test specimen can be controlled via temperature gradients as a result.

Application examples

DC/DC Converters, Inverters

Devices such as DC/DC converters and inverters are key components of the drives used in electric mobility. To test their reliability and efficiency, these components are exposed to different climatic influences. LAUDA constant temperature equipment and systems run through the required temperature profiles within a test temperature range of −40 to 140°C and reliably adjust the load conditions.

On-Board Chargers

On-board chargers (OBC) in electric vehicles must undergo thermal testing as they are critical to safety and performance. These chargers convert alternating current into direct current, generating heat in the process. Excessive temperatures can damage components, reduce efficiency and shorten the life of the system. Thermal tests simulate extreme operating conditions to ensure that the OBC has sufficient cooling and functions reliably, even in high outside temperatures or intensive use. This ensures compliance with safety standards.

EV BATTERIES

Battery performance is a key element of electric mobility. Charge levels, charging cycles and performance are tested in climatic chambers at varying ambient temperatures. LAUDA constant temperature equipment and systems control and monitor the temperature to simulate varying operating conditions and determine if this has any impact on battery performance.

LIQUID COOLED CHARGING CABLES

The use of liquid cooling technology in high-power DC charging cables helps maintain a constant low temperature during charging, preventing thermal damage to the cable and connector caused by overheating. To ensure safe and efficient operation of liquid-cooled charging cables, rigorous thermal and electrical performance testing must be conducted.

ELECTRIC DRIVE

The engine and its cooling system must work reliably and efficiently under different operating conditions. Our Integral process thermostat plays a key role in this by providing the precise temperatures required for reproducible and controllable test conditions

COMPONENT AND MATERIAL TESTS

Parts and components for vehicles are tested for their resilience under extreme conditions using climate and temperature tests. With powerful, variable pressure pumps and direct use of automotive coolant, LAUDA constant temperature equipment and systems pass these stress tests with flying colors. Thanks to the integration of a LAUDA flow control unit, these tests are more precise and can be reproduced more accurately. This ensures the high quality of the components.

The most popular constant temperature equipment of our customers in the automotive sector include circulation chillers and thermostats. These are ideally suited to carry out the following activities reliably and precisely:

Accelerated life tests in the development of batteries and electronic components
End-of-line testing of components in e-mobility
Test benches for electric motors
Endurance tests in fuel cell testing

On request, you can adapt our temperature control solutions for the automotive sector both to the prevailing requirements and to your own wishes. The individual temperature control systems offered by LAUDA can be flexibly extended and modified and are developed individually according to customer requirements.

The right constant temperature equipment for every application

In the automotive industry, test benches, aging tests, quality control and the examination of various engine components are part of daily business. Therefore, for example, you must always be able to rely on correct temperatures during testing, enabling accurate assessment and validation of the device under test. With the temperature control units for the automotive industry from our portfolio, you can achieve this. Our product range includes a large number of units to keep your temperature control processes in the automotive industry up to date.

Examples

Integral process thermostats are used in the automotive industry and by a large number of testing service providers to test batteries, power electronics and eDrives, often in combination with LAUDA flow control or LAUDA filling and draining unit.

Our Ultracool circulation chilllers are perfect for providing central cooling water for Integral process thermostats and ensure a high cooling capacity - even in continuous operation. They are suitable for outdoor installation and also have a temperature monitor that reliably protects the heat exchanger.

LAUDA plans and builds systems precisely in accordance with the customer's wishes: process-oriented, made-to measure and precisely in accordance with the regulations, and in compliance with the strict safety standards. Since the requirements for constant temperature equipment are continuously growing, the modern LAUDA heating and cooling systems are also flexible as far as expansion and modification are concerned.
