1 00:00:03,750 --> 00:00:10,800 Let's understand electric vehicle configurations based on electric drive train or electric motor drive. 2 00:00:11,910 --> 00:00:19,290 There are several ways to connect with the will and on this will differentiate the different configuration 3 00:00:19,290 --> 00:00:23,460 of electric vehicle that is possible for the four wheeler or see God. 4 00:00:25,120 --> 00:00:31,960 The very basic arrangement, the conventional, we can say, is the direct conversion with the regular 5 00:00:31,960 --> 00:00:37,240 Klutch gear and differential arrangement that is used with the base vehicle. 6 00:00:37,900 --> 00:00:48,160 So this is old approach to use the regular car and converting the regular ICBC car to the electric vehicle 7 00:00:48,550 --> 00:00:55,960 with all other arrangements remaining same and connecting the motor, replacing by the icy engine. 8 00:00:57,870 --> 00:00:58,890 So in this case. 9 00:01:00,080 --> 00:01:07,760 This is disconfirmation is used for the purpose when we want to convert the icy base vehicle to the 10 00:01:07,760 --> 00:01:15,920 electric vehicle so it will have the benefit, we required minimum changes in the existing vehicle and 11 00:01:15,920 --> 00:01:17,840 we only need to add the motor. 12 00:01:18,500 --> 00:01:25,820 So in this configuration, bludge is used to connect to our connect or disconnect to our transmitted 13 00:01:25,820 --> 00:01:31,760 from the motor to the will not get the gate is the mechanism. 14 00:01:31,770 --> 00:01:32,860 We will have the several. 15 00:01:33,170 --> 00:01:34,280 This is a gearbox. 16 00:01:34,640 --> 00:01:42,080 So user has the ability to change the gear because I see busway engine cannot work without this because 17 00:01:42,380 --> 00:01:51,380 at low speed hyper queequeg and high speed requirements, we need to adjust the speed torque ratio with 18 00:01:51,380 --> 00:01:58,610 the gate so that with its engine we must require the safety arrangement. 19 00:01:58,850 --> 00:02:04,310 But we will see later in case of electrical configuration, electric vehicle configuration, we can 20 00:02:04,310 --> 00:02:06,340 eliminate the requirement of GEP. 21 00:02:06,800 --> 00:02:13,880 But because this is the configuration used for the conversion purposes, we are using the same transmission 22 00:02:13,880 --> 00:02:20,330 mechanism that is used for the vehicle and only replacing the icy engine with the motor. 23 00:02:20,930 --> 00:02:28,430 So regimented depth and differential differential allows two ways to rotate at different speeds during 24 00:02:28,430 --> 00:02:29,200 the journey. 25 00:02:29,630 --> 00:02:31,880 So hope you all know about the differential. 26 00:02:32,450 --> 00:02:35,210 What is the requirement of differential and why it is use? 27 00:02:35,480 --> 00:02:39,410 If you don't know, I will share one link of one with you. 28 00:02:39,410 --> 00:02:45,710 It will give you the very clear idea about the differential, but most people know about the differential 29 00:02:45,710 --> 00:02:46,810 and its use. 30 00:02:47,540 --> 00:02:49,520 So yeah, we need to understand this. 31 00:02:49,520 --> 00:02:57,010 All additional requirement of clutch, gearbox and differential will add additional weight and cost 32 00:02:57,020 --> 00:02:59,570 to the newly developed vehicle. 33 00:02:59,570 --> 00:03:05,540 But because if we use for the northern purpose, then this is the best suitable configuration. 34 00:03:06,960 --> 00:03:13,050 So differential because we got differential after two whales are connected in common chup then. 35 00:03:14,240 --> 00:03:20,480 It will rotate always with the same speed, so the French will allow the tourists to rotate at different 36 00:03:20,480 --> 00:03:25,020 speeds during the morning because during the turning in the radius, they never will. 37 00:03:25,040 --> 00:03:27,490 And our power will hang the difference. 38 00:03:28,120 --> 00:03:28,280 Right? 39 00:03:28,500 --> 00:03:32,570 There is a tendency to sleep if we do not allow the. 40 00:03:33,860 --> 00:03:38,620 Two bills to rotate at different speeds during the early, so this is the. 41 00:03:39,710 --> 00:03:47,240 Rule of thumb differential, so it's also changed the direction of rotation from the linnear to the 42 00:03:47,400 --> 00:03:47,920 danger. 43 00:03:48,770 --> 00:03:55,280 So Differential Geary's the gearboxes, they're generally view the filing system with the reverse gear 44 00:03:55,790 --> 00:03:58,040 clutch and electric motor. 45 00:03:58,520 --> 00:04:03,060 So this arrangement is that convergent with clutch getting differential. 46 00:04:03,680 --> 00:04:10,120 If we look at the size and weight, then this is the example of clutch plate of the car. 47 00:04:11,280 --> 00:04:16,680 So consider the size and weight of this part, so later on, when we are eliminating this, you will 48 00:04:16,680 --> 00:04:21,120 have no idea about the benefits of electric vehicle configuration. 49 00:04:24,080 --> 00:04:32,990 This is the example of five gear is used for the car with the reverse, so you need to consider the 50 00:04:33,230 --> 00:04:36,610 size weight as well as cost of this park. 51 00:04:37,100 --> 00:04:37,760 So it is the. 52 00:04:39,200 --> 00:04:40,940 When we use the gate system. 53 00:04:42,290 --> 00:04:50,180 If we had a differential differential, also having the significant weight cost as well as differential, 54 00:04:50,180 --> 00:04:57,950 also create the restriction in the ground clearance of the vehicle because the differential in the part 55 00:04:58,400 --> 00:05:02,650 was having the lowest ground clearance for the vehicle. 56 00:05:03,850 --> 00:05:07,990 So that aspect we need to consider when we. 57 00:05:09,030 --> 00:05:12,260 Understand the different configuration of electric vehicle. 58 00:05:15,470 --> 00:05:20,610 Let's see the next configuration with the fixed gear differential. 59 00:05:21,020 --> 00:05:28,220 So we already discussed and compared the four characteristic of CNG engine, and that's quite characteristic 60 00:05:28,220 --> 00:05:29,310 of electric motor. 61 00:05:29,600 --> 00:05:33,860 So yet we do not require the gate system and. 62 00:05:35,100 --> 00:05:45,220 We can use the fix gate arrangement with the motor so that there is elimination of the clutch and get 63 00:05:45,220 --> 00:05:54,390 a box so size and weight to fix get is reduced with compared to gearbox that is required to change from 64 00:05:54,390 --> 00:05:59,800 the one to five and reverse the diesel requirement will be eliminated. 65 00:06:01,020 --> 00:06:03,390 Why the fix gate is required as we already. 66 00:06:04,640 --> 00:06:12,140 Discussed or not, but in case of motor, the generally designed for the high speed and to meet the 67 00:06:12,140 --> 00:06:18,920 maximum speed requirement of the will be required to fix gate arrangement so higher with the fixed get. 68 00:06:18,930 --> 00:06:26,900 We also discussed Mitrokhin produced a sufficient torque during the starting as well as during the maximum 69 00:06:26,900 --> 00:06:27,470 speed. 70 00:06:29,560 --> 00:06:37,100 So fixed yet is having a benefit to it compared to get changing arrangement and still we are raising 71 00:06:37,100 --> 00:06:39,910 the differential in this configuration. 72 00:06:43,790 --> 00:06:50,630 This is the most widely used configuration called the single integrated arrangement in this case to 73 00:06:51,050 --> 00:06:55,960 fix git and differential arrangement in into one unit in the one assembly. 74 00:06:56,390 --> 00:06:58,940 It is called the Single Integrated Arrangement. 75 00:06:59,510 --> 00:07:03,900 So now it is modern electric vehicle used to build vehicle. 76 00:07:03,950 --> 00:07:07,520 They are not converging, but more to the purpose built vehicle. 77 00:07:07,520 --> 00:07:13,520 So we built a purposefully for electric vehicles and we are discussing about the fully electric vehicle 78 00:07:13,760 --> 00:07:14,630 as of now. 79 00:07:15,690 --> 00:07:22,830 So on the single assembly will have the mortar unit again and the differential, it will reduce the 80 00:07:22,830 --> 00:07:26,190 size and weight it compared to previous arrangement. 81 00:07:28,850 --> 00:07:38,330 You read the example of this type of configuration demonstrated by the electric vehicle in the Auto 82 00:07:38,330 --> 00:07:48,740 Expo 2020 held at Noida, so you can see this complete unit becomes smaller and compact and this used 83 00:07:48,740 --> 00:07:52,500 nowadays more widely in the modern electric car. 84 00:07:53,300 --> 00:07:58,580 So up to now in this country configuration that Olá, the single motor drive. 85 00:07:59,090 --> 00:08:04,080 Now, next configuration is the direct drive with that differential. 86 00:08:04,670 --> 00:08:10,500 So you can see we can eliminate the requirement of differential to weight and size of the friction with 87 00:08:10,580 --> 00:08:12,110 the benefit. 88 00:08:12,320 --> 00:08:13,300 It will not be there. 89 00:08:14,330 --> 00:08:16,450 So it is dual motor configuration. 90 00:08:16,730 --> 00:08:18,280 We need to the to motor. 91 00:08:18,740 --> 00:08:25,070 Now, if you consider the cost, generally we require the motor with the half power each. 92 00:08:25,430 --> 00:08:33,290 The total power can be considered as the summation of the modern power will be total power required. 93 00:08:34,430 --> 00:08:38,060 So motor cost will not increase as much as you're thinking. 94 00:08:38,090 --> 00:08:44,090 So it is how Ford Motor with compared to previous configuration and it is attaching both the will to 95 00:08:44,090 --> 00:08:48,170 now both wheels are separately and free to move at different speeds. 96 00:08:48,180 --> 00:08:49,810 So differential is not required. 97 00:08:50,240 --> 00:08:53,270 But we require the electronic control. 98 00:08:53,600 --> 00:08:58,390 Who can set the electronic differential arrangement in this configuration? 99 00:08:58,880 --> 00:09:05,720 We are in the motor with the fixed jet which is attached to the wheel, so it will have the motor and 100 00:09:05,720 --> 00:09:07,540 fixed get set. 101 00:09:08,390 --> 00:09:15,220 So this motors is not have motor and if we consider the configuration, we are going to use the hub 102 00:09:15,230 --> 00:09:19,550 motor also in the two or dual motor configuration. 103 00:09:22,110 --> 00:09:29,970 If you consider this configuration, this mortar attack in the will and mortar, the form of mortar 104 00:09:29,970 --> 00:09:38,670 with the fixed get systems is generally litigation type arrangement is there in hub mortar when we say 105 00:09:38,670 --> 00:09:42,180 the hub mortar with the fixed gear arrangement. 106 00:09:42,480 --> 00:09:48,650 So it will drive with the explanatory arrangements, the dual mortar configuration. 107 00:09:48,930 --> 00:09:55,350 So we will also have the four mortar configuration saying this is the dual mortar configuration in will 108 00:09:55,710 --> 00:09:56,100 drive. 109 00:09:57,370 --> 00:10:05,170 Now, we can also design the mortar like the DCP and Saddam or the special mortar, the hybrid mortar, 110 00:10:06,580 --> 00:10:13,330 which can eliminate the requirement of get if anyone is an electrical engineer, they will know that 111 00:10:13,660 --> 00:10:19,240 they're designing the high speed mortar, which somehow benefited in terms of our weight ratio. 112 00:10:19,510 --> 00:10:24,030 So generally, we prefer designing mortar and the high speed and using the fixed kit. 113 00:10:24,340 --> 00:10:32,320 But now with the ability and SRM and the hybrid combination, we are now able to design the mortar with 114 00:10:32,320 --> 00:10:38,000 the low speed, also eliminating the requirement of even planetary grid arrangement. 115 00:10:39,580 --> 00:10:43,930 So this is the latest configuration that we can use in less drive. 116 00:10:44,320 --> 00:10:46,240 The dual motor configuration. 117 00:10:46,570 --> 00:10:48,070 Can we use? 118 00:10:49,530 --> 00:10:57,210 So as of now, we have discussed the six configuration plus three, that the single last three are the 119 00:10:57,300 --> 00:10:59,100 dual configuration. 120 00:11:00,960 --> 00:11:02,220 What you need to do. 121 00:11:03,410 --> 00:11:11,060 We'll discuss the several things benefits you need to go through the thought process, and before you 122 00:11:11,060 --> 00:11:20,630 go to the next session, just try to knock down the fight of comparison amongst convergent TV and purpose-built 123 00:11:20,630 --> 00:11:22,580 electric vehicle system. 124 00:11:23,700 --> 00:11:29,550 So compare this to and not on The View, but we are going to discuss in the next section, but before 125 00:11:29,550 --> 00:11:35,900 that, you apply your mind and then we will see what are the part, you know, not enough and what are 126 00:11:35,910 --> 00:11:37,880 the people discussing the next session. 127 00:11:38,220 --> 00:11:44,410 So what if we had the convergence of what are the benefits and drawbacks and what are the benefits of 128 00:11:44,580 --> 00:11:47,670 the purpose built electric vehicle system? 129 00:11:51,140 --> 00:11:55,470 You also need to compare the single mother dress with the girl, Martha. 130 00:11:55,940 --> 00:12:01,880 So what are the pluses and minuses of a single murder trial and the type that we are going to discuss 131 00:12:01,880 --> 00:12:02,990 in the next station?
