Battery Management & Junction Box Validation

One essential component in electrical vehicles – besides motor and HV battery – is the power distribution and battery management. These components are located close to the HV-battery and provide connectivity for several components like:

  • Inverters for front and rear axle
  • DC-charger
  • AC-charger, which can be optionally included
  • LV-battery via DC/DC converter
  • The battery power contacts and its cells for cell monitoring

Besides the power distribution itself, additional functionality is added, like contactors, current- and voltage sensors, fuses, and isolation monitors. The latter ones are safety critical components, and in sum a lot of different tests must be performed during validation or end of line verification.

IRS provides solutions for end-of-line-, lifetime- and system-test of battery junction boxes including onboard charger, DC/DC converter and battery management.
