CSM used for development of Formula E race car
CSM measurement technology used for the development of Formula E race car
Formula E-Team ABT Schaeffler Audi Sport develops drive train and chassis, with the support of CSM measurement modules
“The FIA Formula E is an important stimulus for the development of more efficient engine and drive train concepts in the area of e-mobility. We are delighted to be able to support this development with our measurement technology”, emphasises Christoph Mühleis, Head of Product Management and Marketing at CSM GmbH.
In the vehicle development, road test data is used to validate theoretically calculated measurement values thus ensuring the best possible design for the individual components and the vehicle as a whole. When developing its Formula E race car, ABT Schaeffler Audi Sport, mounted the CSM measurement modules directly to the traction battery of the vehicle for test bench tests and during test drives to carry out the required measurements.
For optimizing the chassis, the mechanical stress on the push rods of the axle suspension has been measured with an STGMM strain gauge measurement module. Since cooling plays an important role for the energy efficiency of electric engines, a PTMM temperature measurement module has been used to optimize the cooling system of the drive train, and for measuring the temperature of the oil and the cooling water. The air resistance which for example depends on the height of a vehicle is another key element for energy efficiency. In order to keep the height as low as possible, several laser distance sensors have been connected to two CSM ADMM measurement modules to calculate the optimum distance between the vehicle floor to the road surface.
“We are highly satisfied with the CSM measurement devices. Thanks to the ease of installation, we could always flexibly adapt the measurement setups to the measurement tasks and what's more, there were no failures in the modules, although they were exposed to high stresses. During the test drives the modules were exposed to acceleration forces of up to 5 g”, explains Jens Häberle, Technical Manager e-mobility at the ABT Sportsline GmbH.
Launched in 2014, the FIA Formula E is the first Formula racing series in which exclusively electric vehicles are driven. In the first season of Formula E in 2014/15, all teams started with identical cars, in the current season 2015/16, the teams are free to re-design the entire drive train and the chassis. Ten teams each with two drivers will fight for the Formula E Championship in this season with ABT Schaeffler Audi Sport being the only German team in the field. Contrary to Formula 1, this competition does not take place on the usual motor sport racing tracks, but on ten temporary city circuits hosted by key cities around the world. The only race in Germany will be in Berlin in May 2016, on the premises of the former airport Berlin-Tempelhof.

US Premiere of new ECAT ADMM 4 HS800
Hard- and software to measure data rates up to 800 kHz per channel
US premiere of CSM Products’ new analog measurement module ECAT ADMM 4 HS800 and the new data acquisition software vMeasureCSM at the Automotive Testing Expo North America 2015.
vMeasureCSM is the new easy-to-use data acquisition software for all CSM measurement modules. With just a few clicks the software leads the user from configuration to visualization of the measurement results. The software supports data rates up to 800 kHz per channel. Additionally, vMeasureCSM records video and GPS data. Due to the new software, CSM Products, Inc. is now able to offer all-in-one solutions for complex measurement tasks from one source.
Data rates up to 800 kHz per channel for fast mobile measurements: This is what you get from the new EtherCAT®-based analog measurement module ECAT ADMM 4 HS800. With 4 synchronous inputs the module is ideal for precise dynamic acquisition of signal curves from combustion engines, electric motors and electric auxiliary systems. Thanks to the high protection class IP67 and the operating temperature range from -40°C to +125°C the module can be mounted directly in engine compartments. This reduces noise to an absolute minimum.
Precise A/D and temperature measurements at high-voltage (HV) components: CSM’s CAN-based high-voltage measurement modules allows safe A/D- and temperature measurement at HV components in electric and hybrid vehicles. Thanks to the reinforced insulation up to 800 V and the multi-level safety concept, tested and approved by an accredited test lab according to EN 61010 safety standard, these modules guarantee safe measurement under harsh environmental conditions. At the Automotive Testing Expo North America, CSM Products, Inc. presents two device types: MiniModules for mobile measuring and 19'' slide-in modules for test bench applications.
CSM Products, Inc. presents robust, compact and highly accurate CAN MiniModules for distributed measurements on driving test ranges, road tests and in test benches. The MiniModules provide efficient measurement of temperature (thermo, RTD), voltage (pressure, acceleration etc.), mechanical strain (strain gauges etc.) and RPM (PWM, event counting etc.). Thanks to the high protection class IP67 and the operating temperature range from -40°C to +125°C the MiniModules can be mounted directly in engine compartments. This reduces noise to an absolute minimum.
CSM’s EtherCAT® MiniModules combine the advantages of Ethernet technology and the EtherCAT® protocol to be used in the fields of automotive testing. The modules are ideal for distributed synchronized measurement with high data rates and many channels. The MiniModules offer high-speed measurement with data rates up to 800 kHz per channel and module synchronization better 1 µs.
To integrate high-speed measurement needs into a complex measurement system containing numerous conventional CAN-based devices, CSM's XCP-Gateway plays a decisive role. It merges the data of CSM EtherCAT® MiniModules with data of CSM CAN-devices into XCP on Ethernet frames, synchronizes and aligns the sampling points and provides all data according to the XCP on Ethernet standard.
