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?
