1 00:00:02,160 --> 00:00:02,870 Hi everyone. 2 00:00:02,870 --> 00:00:05,430 Welcome back to BP Solar energy course. 3 00:00:05,450 --> 00:00:10,850 It is the last lecture with this cause z b v solar Petter. 4 00:00:10,910 --> 00:00:16,160 Today we are going to discuss the solos charger control. 5 00:00:16,340 --> 00:00:20,260 Which is what is that charge controller. 6 00:00:20,750 --> 00:00:22,340 Why do we need it. 7 00:00:23,760 --> 00:00:35,810 Notes that they use overcharge your controller is found in b v system with a battery usage in most cases. 8 00:00:35,870 --> 00:00:43,600 This would mean the stand alone beefy system so it's time we're going to discuss in the next section. 9 00:00:47,060 --> 00:00:56,450 We have learned that the importance of having zero right amount of current and voltage being provided 10 00:00:56,450 --> 00:01:05,630 to Betty you know that the battery is innate to chemical device which require a small over potential 11 00:01:06,440 --> 00:01:19,040 when it needs to charge but battery technologies have a strict voltage limitation for 0 0 to all function. 12 00:01:19,040 --> 00:01:26,300 Also that amount of current Santa is a method poised to be v at a rate as a current being this is charged 13 00:01:26,450 --> 00:01:34,400 away boys new home to be with it said a word of limitation for aroma punching offset. 14 00:01:34,460 --> 00:01:45,040 Bethany you have also seen previously how we lead acid risk falls only to over charging and over discharging. 15 00:01:45,210 --> 00:01:56,960 So so common between ZBB artery and zap battery and loot is far from his approach their method. 16 00:01:57,320 --> 00:02:08,870 So this means that we need a device that can interface in steam way between ZBB system and the battery 17 00:02:09,530 --> 00:02:18,560 as a dude and ensures that they take a parameter around as a battery item in then within that battery 18 00:02:18,680 --> 00:02:28,510 manufacturing specification This is where is that charge Control come in 0 7 chargeable to draw better 19 00:02:28,520 --> 00:02:33,470 forms and multitude of their function. 20 00:02:33,470 --> 00:02:41,630 This function can pass zone be enhanced depending on the set of technologies and it's a manufactured 21 00:02:42,900 --> 00:02:47,250 wishes to integrate within as a device. 22 00:02:47,250 --> 00:02:59,070 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 23 00:02:59,100 --> 00:03:08,070 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 24 00:03:08,190 --> 00:03:10,080 who's the battery. 25 00:03:10,080 --> 00:03:13,330 The ability then to overly charge. 26 00:03:13,680 --> 00:03:24,750 This brings about its own set of problems like gas formation and lead acid battery capacity loss and 27 00:03:24,750 --> 00:03:34,970 overheating to name a few that charge Motorola here plays an important role by cutting off said b v 28 00:03:34,980 --> 00:03:37,930 boy from Ohio charging is a method. 29 00:03:38,420 --> 00:03:48,540 Similarly in a set of winter when low regions close the loop do you want to be more the supply power. 30 00:03:49,410 --> 00:03:59,130 Is he really drool means they meant be under such condition tend to be over a discharge which weighs 31 00:03:59,310 --> 00:04:08,880 strongly on Z battery life as this cause is a previous block a charge chargeable draw a lot of under 32 00:04:08,880 --> 00:04:13,100 such a kiss is prevent over this body. 33 00:04:13,240 --> 00:04:20,940 This could make things better he promised a loop for optimum performance the battery voltage has to 34 00:04:20,940 --> 00:04:31,740 be within specified limitation that charge controller can help in maintaining and a low voltage RANGES 35 00:04:31,770 --> 00:04:42,020 so as to ensure that the his operation also is a b v enemy could have its V and b add a different lever 36 00:04:42,630 --> 00:04:49,890 based on temperature at the end of the advanced condition so as a charge controller need to do voltage 37 00:04:49,890 --> 00:04:59,740 regulation to ensure the battery buddy ends a specified voltage range while the v v battery function 38 00:05:00,280 --> 00:05:11,110 as a m BBT this mean zero loading and the charging controller can often does integrated an MBP throughout 39 00:05:11,200 --> 00:05:19,140 of within its design but what is the difference between cell types all of charges. 40 00:05:19,240 --> 00:05:31,450 First before going to this section less traditionally Bloomingdale's are to use the ads EBV banner or 41 00:05:31,590 --> 00:05:33,360 is to live to print. 42 00:05:33,370 --> 00:05:38,790 Is that a bad discharge or is it better he throws a busy area. 43 00:05:38,800 --> 00:05:46,270 This function is also easily integrated now a day in the charger control me. 44 00:05:46,660 --> 00:05:54,580 I wanted to go into too much of the hardware detail but most to charge the controller. 45 00:05:54,670 --> 00:06:04,170 Usually you have is a short Coast converter or series Mark converter kind of controller. 46 00:06:04,340 --> 00:06:08,560 But what is the main difference between the types of solar chargers. 47 00:06:13,700 --> 00:06:20,060 As we already discussed their module voltage and current vary with many different factors. 48 00:06:20,450 --> 00:06:28,010 So we need some say to kids up voltage steady charges embedded and supplies. 49 00:06:28,880 --> 00:06:39,180 There are two main kinds both solar charged control first thought is BW him. 50 00:06:39,350 --> 00:06:44,230 Second time is in BBT algorithm. 51 00:06:44,280 --> 00:06:49,380 What is the main difference between the beta M and M BBT 52 00:06:53,260 --> 00:06:55,110 BW and algorithm. 53 00:06:55,160 --> 00:07:00,290 Use a balls with some modulation missile by using echo. 54 00:07:00,300 --> 00:07:02,540 Better two ways editor Adarand decision. 55 00:07:06,010 --> 00:07:15,190 This vilification of Z BW M what is now old voltage goes down and uses this file voltage but does it 56 00:07:15,200 --> 00:07:17,690 come out of that of Z. 57 00:07:17,710 --> 00:07:20,730 B The NRA which stays the same. 58 00:07:22,700 --> 00:07:33,310 This make the efficiency of the solar charger is less than the BBC other Grayson use a buck all converter 59 00:07:33,330 --> 00:07:45,130 two very easy inputs resistor by changing the current I am bullish mean that voltage goes down to says 60 00:07:45,200 --> 00:07:51,950 specified voltage was invented but as a cut on the way it goes up to cubes out. 61 00:07:52,030 --> 00:08:01,170 BoA is the same as a book both means the efficiency of Z M BBT solar charger control. 62 00:08:01,360 --> 00:08:04,440 Is that about 100 percent. 63 00:08:04,890 --> 00:08:11,100 Let's take an example to differ between BW and immobility. 64 00:08:11,450 --> 00:08:18,180 Let's say we have a module was out of it it involved and 6. 65 00:08:18,300 --> 00:08:19,550 Oh why haven't been there. 66 00:08:20,410 --> 00:08:31,370 If we had been w out Grace on their own volition we would go to twelve volt as a current will is phase 67 00:08:31,370 --> 00:08:42,220 the same means that 0 calm would be six point one and bear means out of the bar of Z be that into a 68 00:08:42,280 --> 00:08:51,630 solo charger will it be six point one times when a Volt will equal to seventy three point two. 69 00:08:51,670 --> 00:09:07,890 What means efficiency of Z BW M and Grizz is about 67 percent us on our hands then BBC solar charger 70 00:09:08,340 --> 00:09:15,150 controller has all but voltage too involved in the same time. 71 00:09:15,510 --> 00:09:22,950 Zack Allen with current when it goes up to nine point one means out of the ball of the Solar charger 72 00:09:23,260 --> 00:09:31,120 will be nine point one times twelve means one hundred and nine point two. 73 00:09:31,130 --> 00:09:45,130 What I mean the efficiency of zips other Grace is at about 99 point 5 percent same BBT principle that 74 00:09:45,150 --> 00:09:58,070 operation depends on the Ivica and Z and go through the system to that sort charge if we say this is 75 00:09:58,130 --> 00:10:08,900 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 76 00:10:08,990 --> 00:10:15,990 and current debate is on that and both resist when we change. 77 00:10:16,000 --> 00:10:17,660 Is that a system. 78 00:10:17,840 --> 00:10:21,260 This law exists lewd. 79 00:10:21,500 --> 00:10:27,860 Will it change between the open circuit and short circuit. 80 00:10:27,950 --> 00:10:38,780 So we need to keep the resistance of input of that shows the cornerstone to key Z. 81 00:10:38,790 --> 00:10:49,960 We want you to operate as that ambiguity but what Z main principle of Z and BBC Z. 82 00:10:49,970 --> 00:10:55,690 I mean the principle of ambiguity is all using a bond bulls. 83 00:10:55,750 --> 00:11:04,910 Did they ambush currency candidate and they ambushed voters signaled to AWB to control the two controls 84 00:11:04,920 --> 00:11:07,820 that both booths converted. 85 00:11:08,040 --> 00:11:12,790 So they do this item of Zippo inverter. 86 00:11:12,890 --> 00:11:23,000 Now you can't control the embittered resistance of that so charge 0 our city missiles for MBC beyond 87 00:11:23,110 --> 00:11:33,050 all incremental conductors on faulty logic control there or many other missiles but then mean missiles 88 00:11:33,050 --> 00:11:43,230 used to date is designed to add incremental conductors and fuzzy logic control high as their efficiency 89 00:11:43,440 --> 00:11:44,670 is so fuzzy. 90 00:11:44,670 --> 00:11:53,920 Motion controller as a 3h this thing is made faster and has an end higher accuracy. 91 00:11:53,920 --> 00:12:05,790 But why do we usually use it beat them in BBT in order to purchase because the price of being that billion 92 00:12:06,330 --> 00:12:10,210 is much less so to Zen and Zen BBT. 93 00:12:10,220 --> 00:12:22,130 So Zacharias with Billy Z rule in our application now is this lecture. 94 00:12:22,140 --> 00:12:33,030 You understood the main difference between Z BW M and the enemy B Team Z time self and BBT and you understood 95 00:12:33,180 --> 00:12:42,780 the function of Z so that is shorter why we need solar charger and we already understood the main function 96 00:12:42,960 --> 00:12:47,140 of the volume and inability to see you in the next block.
