Gantner Instruments Case Study:
October 2019,
MARIETTA, GA ~
Why is this so important? The new 48 Volt battery for hybrids is saving fuel and producing far less CO2 emissions. How? Every time a car is braking, it loses energy. With the help of a so-called boost recuperation system (BRS), the energy can now be stored and used later when the car accelerates again. Thanks to the battery’s housing made of plastic instead of metal and no need for active cooling, the new 48 Volt hybrid battery is less expensive. It is standardized for easy integration into new vehicle models and will make the hybrid system more affordable for a broader market. And Gantner is right in the forefront of this exciting and expanding technology!
The testing of the 48V Battery Management System involved 15 DAQ-systems with a total of up to 60 input channels each, measuring voltage and temperature on the lithium-ion cells with an interface to the clients DAQ software using Modbus, Ethernet and EtherCAT.
Temperature profiles and thermo-mechanical load conditions were simulated to prove the suitability of the new materials and components. Voltage and current were measured and wide range temperature measurements were performed as thermal cycles.
The ability to freely mix and distribute the DAQ measurement modules made the Q.bloxx series the preferred choice. It offers the highest overall system adaptability and expandability and in this particular application, about 700 modules got into action (A101, A104, A105, A107, A124, A127 and A128). All GI Q.bloxx series modules share the following features:
The TC, Pt100/Pt1000 and NTC sensors contributed to the high precision of the temperature measurements and last but not least the permanent galvanic isolation of the channels (1200 VDC).
As controller, the GI Q.station 101 was perfectly equipped for the job with it’s:
