All Singing All Dancing E.V. Charger.

Zoomup
Is this a good one?

    I have installed five Zappis so far, one at 22Kw. British designed and made, way ahead of others  and definitely something to be proud of. They are really targeted at the domestic market for folk with PV but equally spot on for those on grid only. No earth rod needed, load curtailing and open PEN protection using both (iv) and (v) of 722.411.4.1. What I particularly like is the customer service (so far). Wish they had a product for the commercial market, I would have no hesitation in running with them on every project!

    Also take a look at https://www.ohme-ev.com/

    they can connect to Octopus Energy's API to get the latest half-hourly pricing and allow you to charge the car at the lowest priced electricity.

    they are discounted for Octopus customers too.

    "open PEN protection using (iv) and (v) of 722.411.4.1"


    Sounds impressive, who wrote it, the "wiring regulations"?

    You need to be able to use the driverless mode to send the car to plug itself in to charge, like a robotic lawn mower or vacuum cleaner.

    UKPN:

    Yes, good point UKPN. This is a claim by the manufacturer. As I understand it, the (iv) is the usual voltage measurement and the (v) opens all Iive conductors plus the protective conductor to the vehicle in not more than 12ms in the event of current in that conductor exceeding 18mA. 

    I guess that we all need to have a healthy suspicion about claims from manufacturers or, for that matter, third party accreditation bodies about the safety status of products. Grenfell has brought the shutters down on blind acceptance!

    (iv) requires disconnection of PE as well as L & N too.

    (v) seems to leave the door pen for any future bright ideas - I'm not sure why they claim compliance with (v) as well, as the basic operation seems to be covered by (iv).


    I'm still waiting for reports of false triggering of the c.p.c. current monitring - e,g. if the car door touches some earthed metalwork and a small diverted N current flows to Earth...

    I think they are saying that they have covered (iv)but they contend that there are times when an open pen could result in voltages in some properties staying within set limitations but where the car to earth touch voltage can exceed 70v. They have an additional feature that measures current flow in the protective conductor to the car which operates at circa 18mA. I suppose they are claiming that to be (v)

    As to the nuisance tripping, I guess that is a price to be paid for closer protection.

    I need to make a correction to my statement that Myenergi claimed their Zappi product met both (iv) and (v) of 722.411.4.1. I have re-read the manual and the claim is that the Zappi meets 722.411.4.1 (v). Sorry about that, I was sure that I was right but I should have checked!

    Surely the real question here is that you have had  rush of blood to the head and have decided to buy an EV. Q1: assuming that it is available, SP or TP; Q2: which make?
