In order to further optimize efficiency and driving comfort, automobile manufacturers are using integrated starter generators (ISG) in mild hybrid vehicles. Fast current and voltage measurements are crucial for the optimal application of this technology. CSM offers the suitable measurement technology to perform measurements with high data rate and also in mobile testing.
In mild hybrid vehicles, powerful starter generators are used between the combustion engine and the transmission, taking over the functions of the classic starter and alternator. They are capable of accelerating the combustion engine as well as feeding electrical energy recovered via recuperation back into the vehicle battery. Especially during the starting process, currents must be measured at the input for the optimal design of the ISG.
Measurement task
Current measurement for optimizing the integrated starter generator.
Currents of up to 300 A flow in the 48 V vehicle electrical system, which can be much higher for a short time during starting. These peaks also have to be recorded with a high resolution, which means that the measurement technology used must above all allow high data rates and installation for mobile measurements.
With the high sampling rate, the joint solution of CSM measurement modules and Vector software allows a precise analysis of the current peaks that occur and of the power. Vector CANape makes it easy to integrate additional measurement data from ECUs, for example, into the measurement.
XCP-Gateway is the interface between the data acquisition software (e. g. vMeasure, CANape®, INCA®, Vision® ...) and the EtherCAT® measurement modules from CSM. It includes an EtherCAT® master and an XCP-on-Ethernet slave.
Hall-effect-based measurement of highly dynamic currents under harsh environmental conditions: the LEM-sensor packages are optimized for connection to our AD4 ECAT modules.
vMeasure, developed by Vector Informatik, is an easy-to-use software tool for the acquisition and analysis of measurement data that can be used in combination with all CAN- and EtherCAT®-based CSM measurement modules. CSMconfig was integrated directly to ensure swift configuration.
Swift configuration of measurement chains: CSMconfig is the reliable configuration software for all CAN and EtherCAT® based measurement modules from CSM. The clearly arranged and easy-to-use user interface allows an easy setting of all measurement parameters. This helps speeding up the measurement setup considerably.
