Rolec and Tesla issues

[Gavin John Hyde]

I install a lot of EV Chargers from several different manufacturers.
Got a problem that is baffling me though. Fitted a Rolec unit yesterday, standard 32 Amp Type 2 Tethered non smart one as its not OLEV eligible.
Customer has a Tesla S. Overnight it didn't charge.
When we plug the tethered lead in to car it detects the the connector and locks it in to the port. It then says ready to charge but somehow doesn't communicate between car and charger to start.
Charger appears from testing to be fine, If I connect my tester there is 237V, earth fault loop is 0.35 ohms (its on PME in a garage) So not a fluctuating voltage which prevents car charging as Teslas monitor the voltage before and during a charge session and disconnect if it moves + or - 10%
With my charge check connected I press the test button ,get 3 red lights and the contactor in the charger activates to show the communication works as it should and it simulates a charge session.
I have reassured customer that charger and wiring are all compliant and working correctly but its bothering me.
Despite reset of software in car it still doesn't charge. It will charge on the trickle plug in charger, it seems the car has something amiss with its software or charging system.
Do any of you have experience of customers having issues with Teslas not communicating to the charger or not charging. Particularly Rolec units?

Just guessing, but I would have assumed only Tesla chargers work with Tesla cars.

More factual after Googling, some older Teslas don't work with new type 2 chargers.(comms issue)
All new Teslas should.
And any EV can use a Tesla charger, Providing the charger has been set to non Tesla use.

It would not surprise me in the least if they are anything like their diesel and petrol counterparts when it comes to elitism and secrecy.

Teslas can use any type 2 mode 3 charger. The car is new 19 plate and a few weeks old.

Get them to try the car with another charger, there are lots of carparks around with generic chargers for public use.

Have they got the car set to charge only on the 13a plug version and not the Type 2 ?

I have a Rolec (non smart) charger and a Tesla Model 3 and have exactly the same issue. Car charges fine if asked to immediatly but, using the same cable and charger, if set to overnight charge it doesn't. Worked fine for the last year and now just stopped working in this mode. Using a 13A adapter and setting it to charge overnight works fine so it's not the car.

Two different Tesla 3s regularly use my non smart Rolec 7kW overnight with no problems.

Did you ever get a solution to this one @Gavin John Hyde ?

Yes, charger worked with fine with other evs including 2 same model teslas, thankfully the local ev facebook group was good as a few people offered to come test it. based on this Tesla agreed to look at the car in question and changed the on board charger...
We returned the charger anyway as a fail safe, subsequently fitted a zappi.

am seeing increasing number of issues with chargers and teslas... problem is tesla keep changin the tolerances in the sockets on the cars and this causes issues....
