Hi everyone.
Welcome back to BP Solar energy course.
It is the last lecture with this cause z b v solar Petter.
Today we are going to discuss the solos charger control.
Which is what is that charge controller.
Why do we need it.
Notes that they use overcharge your controller is found in b v system with a battery usage in most cases.
This would mean the stand alone beefy system so it's time we're going to discuss in the next section.
We have learned that the importance of having zero right amount of current and voltage being provided
to Betty you know that the battery is innate to chemical device which require a small over potential
when it needs to charge but battery technologies have a strict voltage limitation for 0 0 to all function.
Also that amount of current Santa is a method poised to be v at a rate as a current being this is charged
away boys new home to be with it said a word of limitation for aroma punching offset.
Bethany you have also seen previously how we lead acid risk falls only to over charging and over discharging.
So so common between ZBB artery and zap battery and loot is far from his approach their method.
So this means that we need a device that can interface in steam way between ZBB system and the battery
as a dude and ensures that they take a parameter around as a battery item in then within that battery
manufacturing specification This is where is that charge Control come in 0 7 chargeable to draw better
forms and multitude of their function.
This function can pass zone be enhanced depending on the set of technologies and it's a manufactured
wishes to integrate within as a device.
This mean when the sun is shining in big summer 0 is a lot of be the energy to me as a new the excess
energy is sent to zip it both ways a battery is fully charged and z b v at a rate is the state of coordinated
who's the battery.
The ability then to overly charge.
This brings about its own set of problems like gas formation and lead acid battery capacity loss and
overheating to name a few that charge Motorola here plays an important role by cutting off said b v
boy from Ohio charging is a method.
Similarly in a set of winter when low regions close the loop do you want to be more the supply power.
Is he really drool means they meant be under such condition tend to be over a discharge which weighs
strongly on Z battery life as this cause is a previous block a charge chargeable draw a lot of under
such a kiss is prevent over this body.
This could make things better he promised a loop for optimum performance the battery voltage has to
be within specified limitation that charge controller can help in maintaining and a low voltage RANGES
so as to ensure that the his operation also is a b v enemy could have its V and b add a different lever
based on temperature at the end of the advanced condition so as a charge controller need to do voltage
regulation to ensure the battery buddy ends a specified voltage range while the v v battery function
as a m BBT this mean zero loading and the charging controller can often does integrated an MBP throughout
of within its design but what is the difference between cell types all of charges.
First before going to this section less traditionally Bloomingdale's are to use the ads EBV banner or
is to live to print.
Is that a bad discharge or is it better he throws a busy area.
This function is also easily integrated now a day in the charger control me.
I wanted to go into too much of the hardware detail but most to charge the controller.
Usually you have is a short Coast converter or series Mark converter kind of controller.
But what is the main difference between the types of solar chargers.
As we already discussed their module voltage and current vary with many different factors.
So we need some say to kids up voltage steady charges embedded and supplies.
There are two main kinds both solar charged control first thought is BW him.
Second time is in BBT algorithm.
What is the main difference between the beta M and M BBT
BW and algorithm.
Use a balls with some modulation missile by using echo.
Better two ways editor Adarand decision.
This vilification of Z BW M what is now old voltage goes down and uses this file voltage but does it
come out of that of Z.
B The NRA which stays the same.
This make the efficiency of the solar charger is less than the BBC other Grayson use a buck all converter
two very easy inputs resistor by changing the current I am bullish mean that voltage goes down to says
specified voltage was invented but as a cut on the way it goes up to cubes out.
BoA is the same as a book both means the efficiency of Z M BBT solar charger control.
Is that about 100 percent.
Let's take an example to differ between BW and immobility.
Let's say we have a module was out of it it involved and 6.
Oh why haven't been there.
If we had been w out Grace on their own volition we would go to twelve volt as a current will is phase
the same means that 0 calm would be six point one and bear means out of the bar of Z be that into a
solo charger will it be six point one times when a Volt will equal to seventy three point two.
What means efficiency of Z BW M and Grizz is about 67 percent us on our hands then BBC solar charger
controller has all but voltage too involved in the same time.
Zack Allen with current when it goes up to nine point one means out of the ball of the Solar charger
will be nine point one times twelve means one hundred and nine point two.
What I mean the efficiency of zips other Grace is at about 99 point 5 percent same BBT principle that
operation depends on the Ivica and Z and go through the system to that sort charge if we say this is
XYZ v cut off all the z b b module Z look at it will be in line as this one I mean it's a very low voltage
and current debate is on that and both resist when we change.
Is that a system.
This law exists lewd.
Will it change between the open circuit and short circuit.
So we need to keep the resistance of input of that shows the cornerstone to key Z.
We want you to operate as that ambiguity but what Z main principle of Z and BBC Z.
I mean the principle of ambiguity is all using a bond bulls.
Did they ambush currency candidate and they ambushed voters signaled to AWB to control the two controls
that both booths converted.
So they do this item of Zippo inverter.
Now you can't control the embittered resistance of that so charge 0 our city missiles for MBC beyond
all incremental conductors on faulty logic control there or many other missiles but then mean missiles
used to date is designed to add incremental conductors and fuzzy logic control high as their efficiency
is so fuzzy.
Motion controller as a 3h this thing is made faster and has an end higher accuracy.
But why do we usually use it beat them in BBT in order to purchase because the price of being that billion
is much less so to Zen and Zen BBT.
So Zacharias with Billy Z rule in our application now is this lecture.
You understood the main difference between Z BW M and the enemy B Team Z time self and BBT and you understood
the function of Z so that is shorter why we need solar charger and we already understood the main function
of the volume and inability to see you in the next block.
