Very useful. Supports the theory that all wall chargers are hugely over-priced. There's no exotic circuitry inside them, and heavy copper cable isn't that expensive. There's no reason for EV connector to be nearly double the price of a PS5.
A DC fault in an EV would actually be really, really unlikely to occur, (but i can see why the regs protect against it) 1) the battery in an EV is not chassis (or earth) referenced. 2) The isolation between the battery and the chassis (mains earth when you plug your charging lead in) is generally monitored in real time by an isometer in the battery management unit. Should either DC+ or DC- experience a fault that leads to a loss of isolation, the battery contactors (or pyrotechnic fuses) are opened 3) The vehicles On Board Charger (OBC) itself includes a high level of galvanic isolation (generally 5kV) designed to prevent voltage excursions on the mains supply cascading into the vehicles HVDC system.
Good info so far, but what do you connect it to in the CU? How long does it take to charge a car? How much does it cost in electricity? How much does that unit cost?
Hi Guys, great video. I have one of these but it does not have the DC device you refer to. All the other components are identical to those in your video. Any thoughts on why this would be?
The one I just bought off ebay is the same as yours. It's all the same as in the video, but no DC monitoring device installed. Did you ever get this figured out? Presumably we'd need a type B RCD of 40amps installed at the consumer box as a source for the charge point. I'm just waiting on mine being delivered, and I've emailed the manufacturer for any information and documentation they can provide. If you've got any advice, I'm all ears!
Good stuff. I think a type B needs to become standard for cars. It will only be a matter of time once cost come down to reality. Great insight. Good to see measures are taken to limit the hazard!
@@e5Group all charge points need to be fit with 6ma DC leakage, which can be provided by. type B RCD or a built in 6ma device. Therefore whichever way you design the install a Type B is used or the Type B function has been incorporated.
The center piece, you say, communicates to the "car charger" that is inside the car (6'10"). Is that the car charger or "AC to DC converter"? Great video. Thanks. Will look forward to one with the AC to DC converter built in - that bypasses the converter inside the car and directly charges the battery.
Hi there, I haven't been able to find any installation guidance on these. I note they have a 40A RCD in the pod unit, but then how they connected to the consumer unit in an everyday residential installation. Are you running them to a 2nd RCD in the main consumer unit, or just an isolator switch in that same consumer unit?
If its SWA all the way then you'd typically have a 40A MCB protecting the circuit, either in the existing consumer unit, or inside an additional consumer unit.
Pretty cool how the regulation is built up in the same way in most of Europe. Makes it easier to move across borders. 7-722, EV charging, 722.531.2.101, about the same text in my Norwegian book, but ofc in Norwegian.
@@efixx You should definitely come one day and check out how we do stuff up here in the north when things clear up. It is different in some cases from mainland Europe and the UK.
Hello gents. I've had this unit for more than 2 years and it worked great. However recently the RCD started tripping. I've read some stories about the contact points to the RCD overheating to the point of melting the plastic. I haven't dismounted it yet, so I can't confirm it. Could that be the reason possibly?
@@efixx yes. Guys from charge ev came and replaced the RCD as well as the front panel as it was beginning to crack. This was the common problem with contact point melting.
I’ve bought a send hand 16A 3.kw charging unit, and it does not have this current monitoring unit, so can you buy them separately, because I need to get one, an update video would be good to help people bring their unit up to date!
The term you want to search for is "EVSE module", lots of modules out there you could wire in and replace the "brains" of this unit, though I'd consider this an advanced project! Also familiarise yourself with the requirements for PEN faults when it comes to EV chargers.
The RCD type doesn’t set the earthing system. This is an old video so earth rod needed at the time on TNCS. Now it’s recommended to fit PEN fault protection or a charger with a pen fault monitor.
Most manufacturers can supply replacement leads. The longest lead we’ve seen on a tethered unit is 8 meters. It might be an option to by a non-tethered unit and buy a separate lead to reach 15m.
Great video guys, informative to me as I never really looked at EV charging until I saw this. Now..i'm a sceptical kind of guy.. but is this really just another stealth tax money making scheme in the making?.When fossil fuel eventually goes to confines of history, the inland revenue will need fuel taxes topping up yes?..hmmm how can they do that?.. charging points with tax meters on them? sealed by the utility companies? just like your electricity meter is now?.. that's one tax easily done, the other is manufacturer's of these charging points, test kit, IET releasing new books, regulations, BS7671, another VAT added to joe publics ever decreasing pay packet. I feel we are being forced into EV use, which i'm all for if the infrastructure is in place for it, but it simply isn't and the charging process is a MASSIVE limitation, as are the price of the cars/vehicles, We are just creating work and money for no reason other than "green energy" I won't get into that, life is too short..anyway, this particular charge seems to been thrown together and built to meet current regulations regarding AC & DC earth leakage?.. someone will make a charge point with 1 X 230V AC input and straight out to your car via one device, prob go into your CU like an MCB/RCBO type thing, I'm all for innovation, it's still early days, but interesting to see what's inside that charger, i'm a curious fella, and enjoy your tear downs. If I could offer a word of advice though, please don't be biased towards a company who sends you stuff, please be critical and honest in your reviews, then you will have a great new channel here. Just my 10p worth...for what thats worth?...5p no doubt lol. :-) loving your new venture...and as always, I thank you for your hard work and information...
Thanks for your feedback and some good ideas. Two things are certain in life, death and taxes. From our research, the government will recover the lost fuel taxes via the yearly vehicle duty and perhaps more road pricing schemes. Of course, they could just increase VAT on electricity, but that hits all consumption. With regards to EV chargers, we wanted to understand what's inside to justify the price. We chose the ROLEC unit as they are readily available. many of the others are only available with installation from selected installers. We will be looking at others when we can get our mitts on them. When we can compare and contrast a few units we can make a qualitative judgement on the various user and installer benefits.

@@efixx if they impose high taxes on high speed charging then most people will just charge with a 13amp plug. At 7mph that will give about 100 miles added overnight . With the average comute being about 28 miles that will do for day to day use, remember the high speed public 250+mph chargers are still there for road trips etc
patdbean 7kw, the one we reviewed, is not really considered high speed charging. It’s safer to charge with a dedicated outlet than a 13a socket. The high speed chargers on motorways can be very expensive ~30p kWh - where as night rate economy EV tariffs start at 5p
Every electric car comes included with a BS1363 charging cable, so why would I want to spend additional money on one of these when I could just fit an outdoor BS1363 socket.
Hi. If you plug your car into a BS1363 socket the maximum current you can draw is 13amp but the loading this ways is likely to be closer to 7amps. From the unit shown you can draw about 30amps this means the car will charge way faster... all the best and thanks for commenting 👍
@@efixx yes, a 13amp UK outlet will charge most cars at about 7 mph. Give or take. A 32/40 amp supply will charge between 20 and 30mph. So if you want to get a full charge within the over night economy 7 hours, you need this or something like it.
I think it worked out about £8 a week more expensive to charge over night and day for 24kw a day 5 days a week as it takes 10 and half hours charge.. I get in at 3 am so probably £6 for someone else who can start at 1am when electricity is cheaper.
