We look at how to test an electric vehicle charger installation using the Metrel MI 3152 and a dedicated chargepoint test adaptor A1532. The Metrel 3152 multifunction tester has a number of useful time-saving feature for electricians who are looking to get in the rapidly growing EVSE install market.
Paired with the A1532 adaptor we run through the BS7671 electrical testing requirements to validate the functional testing and safety of an EV charger installation. Including earth fault loop impedance, RCD testing and 6mA DC earth leakage tests.
The tester will compare test results with the required values indicated in BS7671 18th Edition wiring regulations. The Metrel A1532 is suitable for all manufacturers EV chargers. In this video, we are testing a Myenergi Zappi 2.
This is the first in a series of videos featuring the Metrel MI3152.

An amazing bit of kit, I just hope that in time the cost price will fall to a level easier to absorb for the typical one man band electrician

@brendanbeaver8542 4 года назад

Hi David, there are 3 sets of the MI3152, entry set, Standard set and Euro set the difference being the accessories that come in each set. The entry set might be looking at as a starter available through the electrical wholesalers or Test and measuring distributors. The testers in each set all have the same capabilities regarding testing...if i can assist further drop me an email or give me a call brendan.beaver@metrel.co.uk 01924 245 000 / 07554 669 027 MI3152 sets www.metrel.co.uk/uk/shop/EIS/multifunctional-testers/mi-3152.html

Excellent video guys, excellent for the big companies out there installing chargers but with so many test sequences to do and over £2000 for the test kit and lead etc i do not think i will be branching out in EV Charger installs and testing.

@anthonybragg 4 года назад

This was my impression too. Still a good video,are all these tests now required as I have not seen other youtube video's (a lot of those who Gary has had in) do all these tests when installing a car charger?

@brendanbeaver8542 4 года назад

Hi Ashley, EV testing is one of the MI3152 capabilities, Voltage drop, surge protection, power measurement, harmonics and are some of the other functions available! www.metrel.co.uk/uk/shop/EIS/multifunctional-testers/mi-3152.html

@markjohnson1106 4 года назад

Ashley the equipment shown in this video is available for between £1200 and £1500. And it doesn't just test EV installations but domestic, commercial and industrial installations and it does them quickly with its autosequence functions.

@rogerbean393 3 года назад

You won’t regret getting the kit, it’s fantastic. Get the ring circuit testing gadget box and now they do a 3 phase auto testing box. I do use a fluke on site as well but do get a variation on RCD test times. Both a calibrated but it can fail with the Metrel and pass with the fluke. Usually on 5x. Save up and even consider the Mi3155.

Great video gents. Would this full sequence of test need to be carried out at installation and if an eicr was being done? Or maybe the full range of test is more for fault finding?

@PhilipHudnott 4 года назад

Great video. Exactly why I love my Metrel. Are you planning to do any other videos with it? If so take a look at the A1214 easi switch for ring final testing if you can. I also like the memory storage feature for storing the results.

I loved this video and used it to guide me on a Sync EV install. It passed all tests until the dc test did not trip the RCD after injecting 6mA so failed. I tried several times and it still failed at that point. I have no idea what to do now!

@savvyspaces6509 Год назад

Did you have an RCD at source here too? Did you just link out the primary RCD?

@adnanjayousi9140 Год назад

Thanks for the video, One question : Why the toggle switch of the PP is represented by Amps ? the PP is the proximity pilot and it should represent the position of the EV, the CP should represent the Amps because it's role is to control the charge current...so I think at the name plates CP and PP should be switched at the device ? ..

@aktelectricalinstallations9186 3 года назад

Thanks guys. Does the Installation Certificate require all these test results ?

@benjohnson5501 2 месяца назад

No not all. For example you only record 1X test not the others. Pretty clear cut when you fill the form out.

@l4Green 4 года назад

I wonder if the upgradeable software will take into account amendment 1 and the loss of PEN. I assume we will need to test this is compliant. Not sure how - the supply voltage is fixed and the meter measures this rather than alters it. Thoughts?

@efixx 4 года назад

Good point - we'll try to find out!

@l4Green 4 года назад

efixx we don’t test SPD’s, so maybe not. Given the recent amendment, I understand that I can use PME earthing ... if... the charger has the PEN protection - it seems odd that we can’t confirm it indeed does and it works. #trustbutverify

@Andy-71 10 дней назад

If we had a scenario where we had say 4 x 22kw 3ph chargers but some vehicles are only capable of taking a single phase charge. So potentially you could have 4 cars charging defaulting to 7.4kw max all on the brown phase. Would you be better to cross the phases to try and balance out the loads. Most new cars will take a 3ph charge but some will only take a single phase.

@Chris173972 3 года назад

The only thing that trips me up is on the RCD test there was no instructions you have to switch between A & C modes. I know it should be knowledge but most of the other menus tell you what to do, there it just assumes you know what to do next

@tonycowles4150 4 года назад

I thought you used a type A not b on them car charges? 👍

@andyhodchild8 2 года назад

I thought the advantage of a type B was that it didn't need to trip with 6ma dc? I thought that the RDC-DD tripped at 6ma dc to protect a type A RCD from blinding? Are RDC-DD being fitted on lower cost chargers? Not installing, about to retire, just interested as have been doing PV. Also I came across two types of type b rccb's ev and si I guess something that will no doubt need checking.

@efixx 2 года назад

If you install a type B RCD you don't need the 6mA RDC-DD, however if there's an old RCD upstream it could be affected by the DC, I guess that's why most manufacturers put the protection in the charge point. Interestingly a lot of charge point manufacturers seem to be removing the RCD protection from inside their chargers now.

The charger is connected to TNCS - The Zappi charger has PEN fault monitoring.

@@efixx OMG.. I give in.. just watched that.. Round and round we go.. Thanks for the videos.. I've subscribed.. I have the opinion that every day's a school day but to say TT's not as safe seems rubbish.. We quite regularly loose neutrals down here.. We had an overhead 3ph system loose neutral on our surf club on the beach.. Would have hate to see the transient voltages on any extraneous parts if it was PME. Instead we just had the fire alarm blow up and the lights! Thanks.

With ev charges being more common is there a law or legislation in place where these charging point have to be tested periodically in the future?

@efixx 4 года назад

Good question Dewi - we'll look in to this one. The big issue is tethered leads which tend to get thrown around. We've seen some public charge points in an awful mess.

@danielardelian2 19 дней назад

Does anyone have any suggestions on how to test tethered chargers (i.e. the Type 2 cable permanently attached to the charger)?

@efixx 19 дней назад

The tester plugs in to the end of the tethered lead.

@danielardelian2 19 дней назад

@@efixx Thank you for the quick reply. Have you actually tested this? I'm not arguing with you, but I know that standard Type 2 cables are designed such that they cannot be stringed together as "extension leads" (I tried and, as expected, it doesn't work). So if the Metrel plug works plugged into a cable (as an extension lead), then it's probably specially designed for this, which is good.

@deangriffiths9057 2 года назад

Sounds like a load of hassle to me. I did the qualification, and used my own metrel easy test before i put the cover on. So to do the 6mA DC test i will have to spend another £1000+ on new equipment. It would be nice if you didn't have to set switch the cp knob back and forth between each test. Be nice if it was all done automatically!

@efixx 3 года назад

So it can work with different testers (non metrel) - metrel make adapters such as the active switch which work automatically with the test sequence. - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JfBfon0fgws.html
