I charge my EV via 32A Commando and Ohme cable overnight. SWMBO is thinking of getting a PHEV that does not have inbuilt timer capability. I’d like to use overnight tariffs to charge both cars simultaneously. If I were to add a 13A socket on the EV charging circuit for the PHEV's granny cable; can anyone recommend a suitably specced timer that I could install with the 13A socket, or indeed a socket with built in timer?

I guess I'm concerned that domestic timers might not be up to sustained charging currents.

TIA, Mike

What is your EV charging circuit good for, 42A?

RCCB is rated at 63A so I was feeling confident ... but your explicit question's made me look up the Matt:e "Single Phase Voltage Monitoring and Protection Unit" ... whose spec sheet gives "Suitable for 1 x 32amp load".

Hmmm foiled... if I take 13A supply before the Matt:e then I guess I'm back in to the world of driving big nails into my utilities.

Thanks for nudge to remember the Matt:e

Don't know about a plug in timer that I'd trust, but I wonder if an immersion heater timer controlling the socket would do the job. It's been a while since I've had to buy an immersion heater timer, but I think the last one I had was rated to 16A 13A, and you'd hope that they're good for a sustained high current...

Standard disclaimer: this is probably a stupid idea, provided with no warranty, don't blame me if it burns down your house or electrocutes anybody.

EDIT: it was rated to 13A, here's the datasheet: https://04646a9cf351cc0d3888-b8b406...98dedab22e0063dfed0f760b53bd6c.pdf?1583761262
