FORTEST has launched the Dual Absolute T8090, an instrument to solve testing problems in electric vehicle (EV) equipment and improve their performance, reliability, and efficiency.
Many parts of an EV, such as the battery, circuits, cooling systems, and packs, are prone to leaking. To prevent user dissatisfaction and potentially severe loss, these parts must be leak-proof. In particular, off-road vehicles require waterproof battery packs to prevent dust from infiltrating the components and generating performance and safety problems.
To meet high-performance standards, FORTEST combines the traditional absolute-decay approach with an accurate and sensitive differential system in the Dual Absolute T8090 for automotive leak testing equipment.
EV components require testing to verify their safety and quality. Traditional testing methods such as pressure decay, classic differential, and visual testing can be slow and unreliable. There is also a risk of battery pack and other component leaks, which can result in major safety and quality issues if not detected.
The Dual Absolute T8090 has highly sensitive sensors for detecting faults and making measurements, similar to classical differential systems. Due to its circuit optimization and efficient parts, it does not require periodic maintenance, which is necessary in traditional differential instruments. Furthermore, the SSM (solid-state measure) of the Dual Absolute T8090 measuring instrument is insensitive to humidity, eliminating the need for costly compressed air filtering systems.
Battery packs must pass two types of leak testing to ensure its performance and stability. One evaluates the external chassis (IP68) hermeticity, and the other tests the interior cooling circuit of the battery. Using the new Dual Absolute T8090 instrument, the first test is carried out at (50 mbar) pressure with a leak rate of 10 cc/min, and the second is carried out at (1 bar) pressure with a leak rate of 2 cc/min. Measurements of pressure up to 200 bar represent a significant improvement over traditional differential systems.
The Dual Absolute T8090 has a user-friendly interface that is easy to operate without any expertise in design or function. Its front panel is composed of a single sheet of hardened glass and aluminium that makes it easy to clean and appropriate for use in laboratories and on manufacturing lines for testing components of electric cars. The internal panels are well-organized, and the visual display was developed only to show important data.
The modular structure of Dual Absolute T8090 also makes it unique in its features. It includes ports for USB slave, RS232, RS485, Profinet, EtherNet IP, and EtherCAT. A master USB connector is located on the front screen for connecting to a memory device to save test results, backup/restore settings, and update instrument programming. Thermal printers, barcode scanners, and markers are all instantly connected through an internal interface.
Modern production solenoid control valves have allowed for a 30% increase in filling speed compared to traditional models. This improvement in speed has not compromised the reliability and stability of the valves, as component times have also been significantly improved due to the implementation of large-scale leakage monitoring.
