DC fast-charge contactors

The heavy relays that connect a DC rapid charger straight to the pack, bypassing the on-board charger.

How you know it is this

  • DC rapid charging failing while AC charging still works — the reverse of the pattern above
  • A charging session that will not initiate at a rapid charger
  • A contactor fault code

Worth knowing before you buy

  • DC fails and AC works points here. Both failing points further upstream.
  • Inside the pack or its junction unit, so isolation is required.
  • Rapid charging in high ambient temperatures works the whole circuit harder, which is worth knowing here.

What we need to quote it. The chassis number and the fault codes. The chassis number settles the generation, the body and usually the engine in seventeen characters — it is on your mulkiya. A photograph of the old part helps where there is more than one version.
