i'm just looking around the shore here because actually i'm going to let you today
into some secrets of ev charger now behind us we've got some gorgeous looking chargers
from EN + that we haven't seen on the channel before but the first secret is these
actually aren't chargers now people will who have been in the comments before you're right
actually these ac charges don't do any charging whatsoever the charging takes place in the car so
why do we call them ev charges well that's what everybody else calls them and if we didn't do
that you wouldn't find our videos but today we're actually going to look at a fast charger
which brings me on to the next secret i'm going to let you into because sometimes you'll see
these very familiar connectors here that we used to the type 2 connector
which they can charge a car at 22 kilowatts but the actual things itself these connectors
although they may be able to put 22 kilowatts into the car the on-board charger within the car
actually dictates the charging speed and the power that we can charge for batteries at so
you may buy your car plug into a 22 kilowatt charger and then be very disappointed to find out
that it only charges at seven kilowatts because that's what's built into the car now familiar
brands we had a vauxhall core so the other week we would charge at seven kilowatts if you've got
a tesla model three you can charge at 11 kilowatts if you've got a three fair supply if you've got
the x you may be able to go up to 16 kilowatts so if you're buying an ev car watch out for those
expensive editions in there don't worry about the leather interior you may want to trade up to
a faster on-board charger to enable three-phase charging at some of those higher power levels
up to 22 kilowatts but if you really want faster charging we need to be looking at dc charging
which is where this device comes in behind me now it does look like a petrol pump so we can we could
feel a little bit more comfortable car because we know that petrol can obviously put energy
into a car incredibly quickly this charger here behind us has lots of different charging options
but the one we're going to look at today is the dc charging option and this box behind us can put
120 kilowatts of dc charge straight into the car before we take a sneak peek at what's inside this
fantastic box behind us from en plus let's familiarize ourselves with the connectors we use
for ev charging so the ac one will be familiar to most drivers because this is the type two
connector we've got our communication pins there that we've looked at in videos before for that pp
and cp states and then we've got our three phases neutral and the cpc or the earth wire as we may
call it um so that's very familiar people but that's when it comes to dc fast charging let's
pull out this beast here and look at this meaty cable behind us and then you'll see we've gained
an additional two connection points here which are file dc high current charging we've still got our
cp and pp state connectors and our protective conductor there as well and this is what is now
standard for most cars so if you open the flap on your ev car now you'll see a combination
of the type 2 and these two ccs2 connectors here for high power charging so let's have a
little sneak peek at what's inside this cabinet push the release mechanism there yeah we're in
now we've looked at lots of ac charges on the channel before when you step up to dc there's
naturally a lot more inside the charger including actually the electronics to do the charging which
is no longer in the car but let's take a little journey through what we've got going on here so
obviously a very healthy rated circuit breaker at the input of the device so here's where our ac
supply comes in there we've got some extensive emc filtering because obviously there's a lot of power
electronics in the box there you can also see down here we've got all important surge protection
and the circuit breakers for the ac charger that's also on the front of us we're not looking at that
in this video we've done enough of that moving up here's the actual conversion stage itself
so inside behind these panels here is the power electronics to convert the ac into the dc charging
current that we need for the car however there's also two controllers it's still important to
talk to the battery management system in the car because obviously we know batteries it's critical
that you charge them under the right conditions so temperatures are very important the state of
charge of the battery itself in the car is also important because you'll find this dc charging
you can charge very quickly when the car battery is empty it slows down as it gets towards 80
and up to 100 and to do that we've got two communication modules here that talk directly
to the battery charging system within the car to ensure that you may not need actually 120
kilowatts at that particular time it will be regulated to suit the demands of the car itself
now you're probably thinking now who wouldn't want to charge it 120 kilowatts and have one
of these on their driveway so they could charge their batteries in less than an hour well let's
think about the practical implications of charging at this power level so 120 kilowatts well that's
equivalent to almost five regular power supplies that you'd put into a uk home so obviously the
power infrastructure back to the grid to support this is extensive so where would you use dc fast
charging well these are obviously ideal for places where you need to charge cars fast so think of
motorway service stations if you're a business who has possibly a fleet of vehicles possibly delivery
trucks and you want to bring them in get them recharged and quickly back out on the road as
quick as possible and then we also thought those other things think of those car dealerships where
you need to charge a lot of cars in a single location and you don't have a lot of time to do
it in car rentals so lots of car rental fleets are starting to move over to electric vehicles
people typically bring them back at night empty other do in case of electric because they don't
be hanging around to charge them up so you need to turn those vehicles around as quickly as possible
this is the kind of charger that you probably need in there would you have one at home well if you're
a multi-car family and you've got 20 kilowatts available coming into your house possibly you've
got a small three fare supply this might be something we start to see moving forward so
the en plus brand that's probably a new one for viewers in the uk they are one of the biggest
charging brands in china let's just briefly return to slow charging if you've got people hanging
around for quite a while to charge their car well why not throw in some advertising and this
is a product that's coming to the uk later this year where we've got an ev charger with built-in
lcd screen where we can serve up for advertising to offer them a tasty treat while they're waiting
to charge the car or an offer where they can get one at a significantly discounted price so one
last secret well it's not really a secret why are we wearing green t-shirts while we've been down
here at future build we're actually promoting our new channel efix energy where we go way
beyond the world of ev charging and electrical but we've actually strayed into the world of plumbing
into heat pumps into heat storage so if you haven't seen that channel and you're interested in
all these new green technologies for that future building that we're going to be living in check
out that channel i will leave a link for that in the description below but for now fire your
comments here when it comes to fast charging have you installed something that i now know as the
charger rocket behind us have you installed the infrastructure behind it we'd love to have
your experience and your comments about fitting for this type of equipment
