Dual Absolute Leak Tester For e-Mobility Testing Launched

Leak Testing solutions supplier, FORTEST, has launched its Dual Absolute T8090, a new instrument specifically aimed at solving testing problems in electric cars equipment for improving their performance, reliability, and efficiency.

Many parts of an electric car such as the battery, circuits and cooling systems are prone to leaking. To prevent user dissatisfaction and potentially severe loss, these parts must be leak-proof. Off-road vehicles, in particular, require waterproof battery packs to avoid dust from infiltrating the components and generating performance and safety problems.

For car manufacturers and suppliers, leak testing of automobile parts to improve stability and efficiency has become an important aspect of the production system. With the rising demand for electric vehicles, it’s become important to conduct more leakage testing on the whole battery pack and also on charging stations. Therefore, leak test instruments for electric vehicle components must fulfill higher performance standards.

To combat these problems, FORTEST provides a combination of a traditional absolute-decay approach with the accuracy and sensitivity of a differential system, in its new leak testing Dual Absolute T8090 instrument. Traditionally, for various electrical car components, pressure decay, classic differential, and visual testing methods are being used. However, these techniques can be slow and unreliable.

No Compromise On Quality

The Dual Absolute T8090 has highly sensitive sensors for detection of faults and measurements using the classical differential system and does not require periodic maintenance due to its circuit optimization. Traditional capacitive differential systems are sensitive to humidity that can cause severe damage to batteries. 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.

Engineers must pass the battery pack from 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. The full-scale measurement of pressure is up to 200 bar test is more than enough as compared to traditional limits of differential systems.

There is no expertise required for operating Dual Absolute T8090 instrument or understanding its design and functions because of its user-friendly interface. The modular structure of Dual Absolute T8090 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.
