EV Charging Article in E&T Lack of Joined Up Thinking

Roger B

Quite an interesting article in E&T:

How a lack of joined-up thinking could block EV charging expansion | E&T Magazine (theiet.org)

I thought that UK substation fuses were more that 200 - 300A (800A??).

Is the unbalanced phase problem realistic?

Does the 'car to grid' feeding in to the cable and potentially causing an unmonitored overload also apply with other local generation such as solar PV?

  • I was under the impression that the standard single-phase charging rates for an EV were 7.2kW/32A, 3.6kW/16A, with 2kW/10A for "granny leads" on a 13A socket.

    In the long term, with EVs and heat pumps, the solution is to uprate the infrastructure, not getting people to compete as to who is allowed to charge their EV each evening.
