The AU legislation requires a changed measurement principle to measure the number of particles during the periodical technical inspection. With the AVL DiTEST Counter you can carry out particle measurement efficiently. The measuring principle “Diffusion Charging” (electrical charging of particles) and the robust construction enables fast measuring availability without consumables, an exact particle count in a short time and continuous measurements in all-day continuous operation. If required in the future, you can also check petrol vehicles with the AVL DiTEST Counter.

The AVL DiTEST workSAFE is used in the workshop to perform safety-relevant measurements on the high-voltage system of vehicles with an electric drivetrain. In particular, these measurements include verifying the absence of voltage, checking the equipotential bonding and measuring the insulation resistance.

workSAFE allows you to verify and document the deenergized condition of the vehicle quickly and reliably. This is essential in order to safely carry out service or repair work.

With workSAFE you can precisely check the equipotential bonding, to avoid dangerous potential differences between different components of the high-voltage system. In addition, insulation faults can only be reliably detected by the insulation monitor device in case of proper equipotential bonding. Testing the insulation resistance requires applying a test voltage that is at least equal to the battery voltage of the vehicle. workSAFE generates voltages of up to 1500 V DC and is thus prepared for future vehicle generations.

You can as well measure the insulation resistance on the active high voltage system according to SAE J1766. workSAFE is also available in a version adapted to the Chinese GB 18384-2020 standard. Equipped with a pluggable 3rd measuring line, it allows you faster and more accurate measurement results regarding the insulation resistance.

The AVL DiTEST micrΩHM measures the internal resistance of single modules of traction batteries as well as the contact resistances at the connectors between the modules (busbars) and the resistances of the busbars itself. The compact design combined with intuitively guided software allows to carry out the measurements in the workshop – quickly, easily and accurately.

The internal resistance is a key indicator for the state of health of a battery module. A healthy battery pack has both internal resistances of the modules as well as resistances of the busbars low. These resistances may increase with aging or when battery modules and busbars get defective. If a high current is then called up, e.g. when accelerating, the battery can overheat. This leads to a voltage drop and thus reduces the power output of the battery. In the worst case, an increased resistance can even cause a fire in the battery.

By measuring and comparing the internal resistances of different modules within the battery pack, those with increased resistance can be found and replaced. micrΩHM can measure precisely even very low resistances in μΩ-range and is therefore capable to find bad contact points or damaged busbars. Moreover, you can use micrΩHM to assure a proper installation of new modules and their connections, because dirty or not fully tightened busbars will show a higher contact resistance.

The AVL DiTEST noLEAK is an easy to use tool to verify the tightness of the battery pack housings and cooling circuits of all parts in the electrical drivetrain. noLEAK is
designed especially for the workshop.

It is important for the battery to be airtight. Moisture and pollution in the high voltage system could cause dangerous chemical reactions or electrical failure. After
battery repair it is therefore important to check the housing and cooling circuits to identify possible leaks before rebuilding battery into the vehicle. It guarantees
high quality of the repair of the electric vehicle and is a crucial step to assure safety.

noLEAK is a complete solution that guarantees guided and automated procedure for the leak test to meet quality demands during the repair process in the workshop. The system can be offered as a stand-alone application or integrated into your guided diagnostic system.

EValuate is a battery-operated measuring device specially designed for the Periodic Technical Inspection (PTI) of vehicles with high-voltage systems. It is used to measure the safety-relevant parameters of potential equalization, insulation resistance at the AC charging port and to check the immobilizer.

The measuring device consists of a charging port unit, which can be plugged directly into the vehicle's AC charging port, and a connected test probe with integrated display.

EValuate can be used as a stand-alone device or connected to external software via WLAN. This connection allows automatic documentation of the measurement results. Additional information can also be transmitted to the device and shown on the display, for example to ensure that the measuring points are carried out in a set sequence and that no measuring point is forgotten. This enables flexible and reliable work around the entire vehicle.

All measurement results are automatically evaluated by the measuring device and displayed in color so that test engineers are supported in evaluating the results.

The insulation resistance measurement at the AC charging port is fully automated, without manual intervention by a tester. This significantly reduces the risk of operating errors and enables time-efficient work.

HIGH-SPEED EMISSIONS TESTING FOR PETROL AND DIESEL ENGINES

When it comes to measuring exhaust gases, we at AVL DiTEST believe that our
devices should ease your workload in workshops and testing centres, reduce your
costs and comply with current standards. The new generation of AVL DiTEST MDS
stations does precisely this and is extremely easy and intuitive to use whenever
you need it. The proven modular concept means you get more out of your device,
while short cycle times and precise measurements help you establish profitable
workflows. We develop emissions measuring technology for real professionals
and real challenges.

Since the requirements for electric vehicles are very extensive, universal solutions for tools are becoming increasingly important. In order to meet these requirements, AVL DiTEST has developed the versatile tool HV Sat.

The HV Sat can be used in different applications, for example as a proof of the correct activities after the repair work, as an overall inspection on stored batteries, up to a completely safety test of the battery before further use or disposal. You can use this tool to check, among other things, voltage resistance and zero voltage level, check leakage of a battery housing or measure insulation resistance previously to the mounting on the vehicle. Practically packed in two transport cases.

CO2 air conditioning system (R744) is superior to the current R1234yf system in terms of efficiency, cooling dynamics and environmental sustainability. Reputable automotive manufacturers have recognised its potential and will in future be putting their faith in CO2, the natural, ecological and advanced coolant. AVL DITEST is supporting the automotive industry with unique, state-of-the-art innovations. Together, we have developed the ADS 310 air conditioning service device so that for the first time, garage workshops are also able to carry out repairs and maintenance on CO2 air conditioning systems. Safety, environmental protection and economic efficiency were, of course, at the forefront of the development programme for the device.
