will hep us if you let us know what type/make your home charger is?

It is a charger provided by company known as clever. It was manufactured by KEBA. Model number is P30.

 

You may be overloading the chargepoint or causing it to heat up (a cable connection internally not tightened properly)
As you have a Tesla turn down the charging current to say 16 Amps and see, if it keeps charging longer get the chargepoint seen to.

 

hmmm, interesting problem. I wonder if it could be related to your home's electrical setup? might be worth getting an electrician to take a look, just to rule that out.

And where you are located. Your posts show a Danish flag. The circuit protection that is used locally may have an impact.

 

What happens when it stops? Controlled stop, or some emergency switch trips?

In UK, chargers are required to shutdown if the supply voltage goes outside the permitted range. This can happen if too much solar electricity is generated locally & the voltage goes >253V, or your house is at the end of a long wire from the transformer and a large load drags it to <216V. You may have similar limits, worth checking your AC voltage while a charge is starting up and then dropping out. Never happened to me, so no idea if it auto-resets or what.

Another problem I had was my first ever 32A charge failed after about 10 minutes, the Breaker tripped out. It was rated 32A. These items warm up in use, bi-metallic strip is used to cut the power if too much amps used, so they de-rate slightly as the temperature rises. Mine derated to 31.5A when temp rose to 30C in the CU box it was in. Fix was to replace it with a 40A equivalent, fine ever since.

 

Could be a grid voltage issue. My Tesla did that when our supply voltage went out of specification due to a fault on the substation (fixed within 12 hours of me reporting it, very impressed with UKPN!).
