A consortium led by the Bosch Group has developed a standardised integrated diagnostic system, which will be able to identify and locate defects in the electrical powertrain.
The consortium’s work on diagnosis and repairs for electric vehicles, dubbed DINA, is a EUR2.8m (US$3.1m) project funded by Germany’s Federal Ministry of Education and Research as part of the ‘Electric Mobility South-West’ cluster.

The results of the research have implications for suppliers, automakers, workshops, and testing organisations.
As well as the Bosch Group, the consortium included Dekra Automobil, the Fraunhofer Ernst-Mach-Institut, and the Research Institute of Automotive Engineering and Vehicle Engines Stuttgart (FKFS).
From July, 2012 to July, 2015, part of the DINA project was drawing up standards for the diagnosis and repair of high-voltage systems in electric vehicles and researching suitable measurement methods.
Consortium members also created an integrated diagnostic system to help detect and localise problems in an electric vehicle’s powertrain, from the high-voltage battery and inverter to the motors and charging system.

By GlobalDataThis allows workshops to carry out ‘modularised repairs.’ If it is possible to precisely determine where problems lie, there is no need to replace whole systems.
Instead, in the future it will be possible to pinpoint and replace defective parts individually.
This makes repairs not only faster, but also more affordable, claims Bosch.
