Hello,
we spotted this today and wondered what the purpose is:
HV+ and HV- pass through it on the way to the inverter & charger.
The 6mm2 going to the heater do not pass through it.
It seems very weak, barely pulls on a screw.
I measured 5kOhm resistance on it.
We assume EMF?
Is it a Ferrite Bead? https://en.wikipedia.org/wiki/Ferrite_bead
(Solved) What is this weak magnet wrapped around 40kWh box bus bars?

A ferrite bead (also known as a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke[1][2]) is a type of choke that suppresses high-frequency electronic noise in electronic circuits.
Yes it is.

Neat, thanks! Surprised not all cables are passing through it.
