Functie omschrijving

Problem definition

To test BMS firmware, a lot of tests need to be done. This is now done manually, which is time consuming, error prone and not always as easy to reproduce. To mitigate those disadvantages, we want to make a BMS tester which consists of modules which each can control one of the inputs to the actual BMS:

  • Cell voltages,
  • Battery current,
  • Cell temperatures,
  • Relay interface.

These modules must be controllable via communication, preferably MB.

Goal of the project

Create at least one of the modules for the BMS tester:

  • Setup the requirements (in consultation with the LiIon team.
  • Draw a schematic
  • Draw a PCB
  • Have the PCB made and assembled
