Marquardt to showcase latest portfolio at Battery Show Europe | Autocar Professional


At the Battery Show Europe, to be held in Stuttgart, Germany from June 18-20, mechatronics specialist Marquardt will be showcasing its broad portfolio of components for battery and fuel cell systems.

The global operating company will showcase production-ready battery management systems, sensors for hydrogen fuel cells and components for digital vehicle communication and positioning with Bluetooth Low Energy (BLE) and Ultra-Wideband (UWB) technology. The new Interactive Charging System (ICS), a fully automated charging solution from Marquardt, which makes robotic charging possible, can be seen live for the first time. Marquardt will also be providing insights into the development of new control units for wireless cell monitoring of battery systems, H2 safety and contactless level measurement in liquid tanks.

The production-ready HV sensor from Marquardt disconnects the vehicle electronics from the high-voltage battery in just five milliseconds.

Extremely fast HV sensor and wireless cell module controller
In the field of battery management systems (BMS), Marquardt offers complete systems as well as standardized and scalable components. A the Battery Show, Marquardt will focus on its high-voltage sensor. Compared to conventional sensors, the innovation measures current and voltage extremely quickly and accurately.

In the event of an overcurrent, the battery management system can react within just five milliseconds and disconnect the vehicle electronics from the high-voltage battery. Thanks to its scalable design, the HV sensor can also be adapted to the customer’s requirements from specification to production in a cost-friendly way. 

Marquardt will also be presenting the new Cell Module Controller (CMC), a comprehensive measuring unit that monitors and controls cells in electric vehicle batteries and stationary energy systems, offering reliable safety and performance.

New sensors for H2 leakage and water level
Marquardt’s BMS components are suitable for mobile and stationary applications as well as for battery-powered and hybrid systems and drives with fuel cells. In the field of hydrogen applications, Marquardt will be showcasing the Cell Voltage Monitoring System (CVM) and the Cell Voltage Pick-Up (CVP) for direct measurement of cell values. Marquardt will also be showcasing its development expertise with new sensors for level measurement and hydrogen leakage detection.

New in the hydrogen sector: the H2 leakage sensor and the water level sensor from Marquardt. 

The new H2 Leakage Sensor reliably detects concentrations between 0 and 4 percent of the highly volatile and flammable gas. This makes it an important safety-relevant feature for the storage and operation of hydrogen systems. The possible applications are diverse and range from monitoring and securing heating systems to electrolysis and use in drive systems.

With a new Water Level Sensor, Marquardt also offers the option of contactless level measurement. The new sensor detects without contact to the medium for example the fill level of wastewater tanks in internal fuel cell vehicles and indicates when they are empty.

Robotic charging
Robotic charging, which means fully automated charging solutions in interaction between a charging station and a vehicle, is opening up numerous fields of application in the future. This primarily includes autonomous valet parking with an automated charging process for electric vehicles.

With the new Interactive Charging System (ICS), Marquardt is presenting a fully automated charging solution for the first time.

The positioning of the vehicles in the parking garage and the charging process by a robotic arm at the charging station are carried out autonomously and independently of the vehicle manufacturer. There are further opportunities for robotic charging in the truck and material handling sector as well as in mass charging for fleet operators and in intralogistics.

Marquardt’s Interactive Charging System (ICS) and the Smart Access PnD3 offers vehicle manufacturers around the world central components that make their vehicles robotic charging-capable. The ICS with the integrated E-Lock locking module from Marquardt, which will be presented live at the Battery Show Europe, can be combined with the various global inlet standards (CCS, NACS, ChaoJi, CHAdeMO, GB/T). In addition, it is currently the only charging system to offer the option of an automated charging flap in combination with sensitive S3 button technology and a motorized inlet port cover, one of the basic requirements for future autonomous charging.

Digital key sharing as the basis for robotic charging
With the PnD3 keyless driving authorization system, Marquardt also provides the basis for digital key sharing in exchange with the robotic charging station. The vehicle is positioned using Ultra-Wideband (UWB) technology, while communication with the charging station takes place “over the air” via

Bluetooth Low Energy
As a member of the Car Connectivity Consortium (CCC), Marquardt attaches great importance to using the already standardized CCC communication for digital key sharing as the basis for robotic charging. 

At the Battery Show Europe 2024, Marquardt will show how the interaction between vehicle and charging station works in detail using a fully automated demonstrator and in a 3D animation, which can be seen at this link:
