Development of an on-board battery charger

Infinergies

INFINERGIES is an engineering and design company specialized in power electronics. Its services cover all the stages of a new product development project: analysis, definition of requirements, design and simulation, prototype testing and validation.

Technical/scientific Challenge:

  • Involved in the development of an on-board battery charger for electric vehicles, Infinergies was faced with the problem of the cumulative duration of the simulations to be carried out.
  • The product must be able to charge the battery, but also supply electricity to the grid, or power sockets in the vehicle, regardless of the battery's state of charge.
  • This requires a large number of simulations to test these numerous operating cases.

Solution:

Over a one-month period, launch of 140 calculations (single-core) with an average duration of 12 hours, thanks to :

  • the available memory (60 GB of memory required for each calculation, i.e. half a Myria supercomputer calculation node)

  • the ability to run several calculations simultaneously;

  • continuous support from CC-FR for setting up calculations on the supercomputer, and for linking calculations together.

Business impact:

Infinergies had avery tight schedule. The help they received from CC-FR and CRIANN in setting up their simulations on the supercomputer was extremely effective, and then the access to the computing power enabled them to solve their industrial problem within the deadline.
