EV general discussion

Octopus will likely split the meter tails, install an additional external consumer unit, clip the cable externally to where you want the charge point and call it done.

You’ll need to make sure your CT clamps are in the right places.

As for the battery safe mode, they only work when you are solar charging. If you are grid charging, they can’t stop your battery emptying itself into your car if it can ‘see’ the load from the charger.

Who ever installs it, just make sure they know what you want and where your solar/battery CT clamps are and how they can be positioned to make sure they can’t see the load from your car charger.

ah goddamn :( i've just sent octopus and email to see what they will say.
or should i just stump up the £250 extra then?
 
Radar yes, LKA no

Edit: actually both were working on the trip home but have also been funky recently


Front camera deffo not though
Someone has crashed into your bumper most probably. The brackets are sacrificial, and designed to bend easily to a)not damage more expensive equipment and b) evidence to the dealer / workshop that it's had a bump, and therefore not covered under warranty
 
FWIW, my Leaf gives back about 400kWh/month to the house. Works out at about £100/month saved on leccy. We cook on electric too.
Damn, I assume you must have electric heating?

Family of 3 with the house occupied most of the time (wife works from home) and our total electricity bill is only £79 a month including charging a PHEV every night. We go have gas for heating and hot water though.
 
Finally have power back on, a day earlier than anticipated, those SSEN engineers don't waste time!

The Vehicle To Load worked wonders, all EVs should have it.

I was fitting a PPF strip to protect the rear bumper lip of the CX60 earlier. Final step is going over it with a hairdryer or heat gun. Seeing as the battery has been charged at the lower rate overnight, I used the 3 pin socket in the boot to save myself some pennies. Score!

It'd only 13kWh per day, some people own a Leaf to literally just use as V2H and not as a vehicle.

I'm not sure which part of my post you are concerend with but splitting the meter tails and wiring the charge point into its own consumer unit as the very first thing after your meter is what you want. It means you can place your CT clamps for your solar between it and your house consumer unit and they will not see the demand from your charger.

As for surface clipping the cable, for this price you do need to manage your expecations, it should be expected they will take the easest route to the charger which may not be the neatest.

Ah! Basically this then?

I'm assuming the downside is that my Sunsynk app won't be able to give me an accurate reading of leccy consumption because the EV charger is outside the PV circuit.

I've planned a route already, hopefully I'll just tell them how to wire it up and will get done :cry:
 
Yes, spot on.

If the electrician doesn't understand, give them that diagram and they will. If you have a planned route and it meets their criteria (e.g. not too long and not taking the pee with how many holes they need to make) it should be fine.

Correct, the downside is the inverter will not report your total energy use but you can get daily/weekly/monthly data from the hypervolt and excel exists to mash it all back together. The upside is not having a rage out when you realise octopus has charged your car ar 3pm on a mid-winterd day and emptied your battery.

yeah it's only 5m from where the supply is, and where I want the box to end up
octopus says less than 10m, so it should be okay

Thankfully I'm on eon next drive, so in theory all this malarkey doesn't even affect my use (ie charge from 0000-0659) currently :cry:
but I'd like the circuit to be sorted properly just in case i jump to IOG or eon next smart

seems a good description of ct clamp positioning

Addressing Integration Challenges

Integrating an EV charger with a solar PV system can present challenges, particularly with regard to the CT clamps’ placement and the potential for unintended battery discharge. The positioning of CT clamps is critical in this setup. If the inverter’s CT clamp is placed before the EV charger’s CT clamp, the system can misinterpret the load from the EV charger as a household demand, causing the inverter to discharge the battery to meet this demand.

This situation arises because the CT clamp on the inverter detects the current flowing to the EV charger, leading to a potential discharge of the solar battery, which is not ideal for maximising energy efficiency. To avoid this, it’s essential to ensure that the CT clamp on the inverter does not include the load from the EV charger in its readings.

Nope, gas boiler for hot water and heating. Family of 4 here (two teenage boys) and I work from home.

Who’s your supplier?

description of model3 door handle design in that articles brief audio excerpt - had never heard that on pre highland models in an emergency situation, door handle to escape rear is obscure

I’d like to listen to the whole thing, whilst I agree the secondary mechanical release is obscure if unfamiliar (same applies to the front to a lesser degree), it’s also not the primary method of opening the door and I note that electronic door release are being seen or other brands now and they also have obscure mechanical overrides.. This tells me that the data and regulatory technical reviews have accepted the risk acceptability for that design and it deemed still fit for purpose.

I’d still rather have mechanical latches as the primary method, but you soon forget about it when you live with the car, I actually find mechanical door pulls feel a bit weird and old fashioned.

Listening to the BBC podcast, on the surface it sounds all exciting, but actually all it's saying is Tesla, a car manufacturer gets thousands of complaints.. it doesn't say if they are investigated, what the root causes are and what regulatory responses there are to all that... I'd love to see the data and see if they have been naughty or this is just a fairly normal case of 'cars are dangerous, manufacturers have to deal with the fact many deaths are avoidable but still have cars on the market and a regulatory framework that allows people to die'.

FYI, With adaptive cruise control that has a stop/go feature I imagine many cases of 'my car suddenly lurched forward' are simply forgetting adaptive cruise is on and you are in a queue of traffic etc, get to the head of the queue and it suddenly shoots off.. I've had two people in work complaining about their new EVs that have done similar (none Tesla, both have stop/go adaptive cruise), as they have also complained of phantom/sudden braking.. usually (like my ID.3) it's picking up speed limits from slip roads on motorways, or side roads etc.. Even my Mustang (adaptive cruise with forward collision system) will jam on needlessly in some fairly trivial circumstances..

Tesla have been investigated many times for their autopilot by several regulatory bodies, and made tweaks.. everyone focuses on Tesla, which is fine, but my ID.3 used to just switch off autopilot with zero warning which even with hands on wheel ready to take over can be disconcerting and having driven a fair few MEB cars with travel assist, they all do that occasionally.. In my Model Y it flashes/beeps to alert you before it can't handle things, but ultimately it does get in situations it can't deal with..

I'm not admonishing Tesla, I think it's popular to pick on them these days, but the reality is, issues happen, what matters is what the regulatory bodies are aware of and accepting, if this exposes that, great.. if it exposes some true hiding of data from regulatory bodies, that's great too..

On the door pull point, let’s not forget that mechanical linkages are not exactly risk free either. They can get damaged or get jammed in an accident or the door itself gets pinched up against the body and jams.

If it was found to be that big of an issue, we probably wouldn’t make 3 door cars and yet we do. Those 3 door cars are sometimes coupled with rear windows which don’t wind down either so your only option might be to break it to get out of the back which is easier said than done.

This seems a terrible (and dangerous) implementation to me - in my Niro, if the adaptive cruise brings the car to a complete stop for more than a fraction of a second, I need to manually set off again by pushing the cruise button on the wheel or tapping the accelerator pedal

Most implementations of stop/go allow 20-30 seconds stationary before requiring a manual intervention, doing it immediately sounds not that well thought out, on the basis stop/go systems are linked to safety, so if you make it inconvenient/unworkable people won't use them.

Note, Tesla keeps activated for a long time (I've never experienced it actually disengaging in any stop/go traffic) which I think could be improved..

Hell, I was driving a manual van the other day with adaptive cruise, it let you change down/up as needed without disengaging and I'm sure I wasn't dreaming when it (from my recollection) even allowed some trail braking when over speeding without disengaging the adaptive cruise, I actually remember being surprised when I took my foot off the throttle in some situations and it started speeding up after I'd changed gear and/or slightly braked.

This is why we need data across the industry, we have so many cars around that data should show what does/doesn't work and whose hypotheses are right/wrong..
