1 for Electrical Vehicles Dr Jürgen Braunstein, CSM Jason Mistry, Vector GB < Innovative Measurement and Data Technology

2 CSM Background Founded in 1983 next to Stuttgart, Germany R&D and production of state of the art reliable and cost effective measurement devices Configuration software Data output on CAN, EtherCAT, XCP on Ethernet Vector Informatik GmbH bought 24.8 % of CSM's shares in 2015 for Electrical Vehicles 2

3 Vector GB Background Vector Informatik GmbH provides a platform of tools, software components and services for developing embedded systems. Vector GB Ltd started in 2009 to support UK and Ireland customers. Areas covered include ADAS, AUTOSAR and ECU Software, ECU Testing and Calibration, Over The Air Diagnostics, Development of Distributed Systems, Car2x and Functional Safety. Vector tools aim to make this complex topic as simple and understandable as possible. CSM and Vector are able to offer a comprehensive solution for online acquisition, analysis and management of measurement data. for Electrical Vehicles 3

4 CSM System Overview for Electrical Vehicles 4

5 CSM Measurement Modules Classical Sources Temperature (thermo couples and RTD's) Voltage, Current Pressure Acceleration (ICP/IEPE) Mechanical strain (strain gauges) Displacement Frequency, period, PWM, revs, pulse length, counting events, delay times CAN/EtherCAT/XCP on Ethernet for Electrical Vehicles 5

6 CSM HV Measurement Modules 1/2 HV MiniModules CAN and EtherCAT For mobile use extremely compact, very robust and precise For installation close to the sensors IP 67, 40 C to +100 C HV 19 modules for rack mounting Ideal for high channel counts, as precise as the HV MiniModules Use the same modules in test benches and in vehicles (trunk or passenger compartment) IP 65, 40 C to +85 C for Electrical Vehicles 6

7 CSM HV Measurement Modules 2/2 HV Breakout Modules (BM) for in vehicle testing and dynamometer measurements Safe measurement of voltages up to 2 kv Safe measurement of currents up to 1.4 ka CAN and ECAT output, up to 1 MHz for Electrical Vehicles 7

8 From Physical Data to Modelling and Design Verification CSM delivers physical data from almost any sensor at data rates up to 1 MHz CSM's and Vector's data loggers or PC's can be used to acquire data Durability analysis Transients, e.g. misfiring Spurious effects in electronics for Electrical Vehicles 8

10 Calibration and Measurement Tools CANape for Electrical Vehicles 10

11 Calibration and Measurement Tools CANape CANape is a professional tool for measuring, calibrating and analysing data Data might be from within an ECU, from a network, or external measurement device Multiple log files can be displayed synchronously Data within an ECU can be calibrated using XCP on CAN, FlexRay or Ethernet Data mining allows the automatic generation of reports using multiple log files for Electrical Vehicles 11

12 CSM + Vector The Best Solution Physical data for modelling from CSM's modules Set up of CSM's devices out of CANape High flexibility Comparing real world and models with CANape Closed loop for calibration for Electrical Vehicles 12
