Energy Infrastructure

Especially in today's world, the provision of energy is becoming increasingly important. What was once commonly "fuel" in the form of gasoline or diesel is now expanding to include electricity and other sources of energy (e.g., hydrogen). This poses ever-new challenges for infrastructure and requires technological solutions to meet the new requirements.

AST's sensor solutions play a key role here. For example, our sensor technology for detecting hydrogen leaks is an important safety feature in hydrogen refueling stations as it can detect even the smallest concentrations of highly flammable hydrogen gas in the ambient air and indicate possible defects.

Likewise, AST ensures safety and transparency in the aera of fast-charging infrastructure with its energy meter that complies with calibration regulations. Our meters therefore not only meet the legal requirements, but above all, protect the consumer from manipulation and billing errors. In addition, our current sensors are already designed for future requirements in the field of megawatt charging, allowing our customers to be ready to face the future.

DC METERS (compliant with calibration law)

Sensors for measuring current and voltage in charging stations

The continuous measurement of high currents and voltages is a challenging task. Based on 3D Hall ASIC technology (AST patent) developed in-house, the AST DC meters enable continuous measurement up to 1,000 A and 1,000 V. This high measuring range especially qualifies AST sensors for use in fast charging stations as well as in megawatt charging stations for the bus and truck sector.

AST DC meters comply with German calibration regulations and meet the requirements of the following certification authorities:

UL certification (US)
German calibration law, certified according to Modules B and D
MID certification
French calibration law (Décision n° 22.00.570.001.1 du 1er mars 2022)
UKCA Certification

Even under continuous loads of 1,000 A and 1,000 V, the AST DC meter meets the Class B requirements of MID 2014/32/EU and accuracy class 1 of IEC 62053-41:2021.

To take account of trends in charging station infrastructure at an early stage, our DC meters are already designed for bi-directional charging processes.

The DC Meter is available in two different designs: as a compact measuring unit with an integrated display or as a version with a remote display and greater flexibility in complex installation situations.

Hydrogen Sensor

Sensors for measuring concentrations in hydrogen and fuel cell systems

Hydrogen sensors are based on the very robust and reliable TCS process and are therefore predestined for this task. In particular, they exhibit low cross sensitivity to other gases and are extremely stable over the long-term.

Our sensors are available in different versions:

As a leakage sensor (0-5% hydrogen content), they are part of the safety concept of hydrogen-powered vehicles. Detecting leaks in the hydrogen supply is especially essential for ensuring safe operation when using the critical medium of hydrogen.
As a concentration sensor (0-10% hydrogen content), for example, they are used in the exhaust tract of the fuel cell and enable conclusions to be drawn about the efficiency of the process.
As a concentration sensor (0-100% hydrogen content), they are located on the anode side of the fuel cell and measure the hydrogen content in the recirculation circuit.

Air Quality Sensor

Sensors for detecting the air quality

Air quality sensors constantly monitor the intensity, degree of pollution, and number of odor molecules in the exhaust air. This information can be used as a basis for adjusting fan performance to produce a pleasantly fresh ambient climate.

By continuously measuring air pollution, our sensors intelligently predict when, for example, filters need to be replaced or the next service is due.
