1 00:00:01,800 --> 00:00:09,030 In this situation, we will try to understand simplified block diagram of electric vehicle later on, 2 00:00:09,420 --> 00:00:11,940 we will also discuss about the different configuration. 3 00:00:12,300 --> 00:00:18,600 But yet present in this situation, we will discuss about the simplified block magnum of the electric 4 00:00:18,600 --> 00:00:19,130 vehicle. 5 00:00:20,900 --> 00:00:31,800 So vehicle in general is done nothing but the mass, which is having some weight and inertia that has 6 00:00:31,800 --> 00:00:34,910 the mechanical parameter to represent the linear motion. 7 00:00:35,790 --> 00:00:43,950 So we call if we can consider any object, if we apply the force, depending upon the frictional losses 8 00:00:43,950 --> 00:00:52,170 and weight of the vehicle and the gravitational constant, it will result in displacement according 9 00:00:52,170 --> 00:00:53,390 to the applied force. 10 00:00:53,400 --> 00:00:58,230 If this continues, the displacement and the spirit will remain continuous. 11 00:00:59,010 --> 00:01:07,320 And Wacol is the object where we are interested in reducing the friction ground friction. 12 00:01:07,320 --> 00:01:16,530 So friction is minimal because of the wheel arrangement, so will make it possible to reduce the frictional 13 00:01:18,060 --> 00:01:18,900 as minimal. 14 00:01:19,140 --> 00:01:26,640 Less sufficient friction is also required for the traction movement so that duty will be complicated 15 00:01:26,640 --> 00:01:36,000 by the wheel and bearing arrangement will almost reduce the friction to the negligible value after rotating 16 00:01:36,000 --> 00:01:38,280 south of the motoring wheel. 17 00:01:38,820 --> 00:01:40,580 So bearing an element is also death. 18 00:01:41,670 --> 00:01:48,980 So accordingly we will have some frictional constant that we will assume the mathematical representation. 19 00:01:49,380 --> 00:01:57,000 But at present, if that is the some object with the mass where the friction is less than if we applied 20 00:01:57,000 --> 00:02:00,660 the force, then it will result in displacement and velocity. 21 00:02:00,660 --> 00:02:07,590 And depending upon its value of mass and inertia, we can easily represent in the mathematical form 22 00:02:07,590 --> 00:02:10,680 and we can get the final displacement as well as the velocity. 23 00:02:12,210 --> 00:02:15,930 So what is happening here is electric motor. 24 00:02:15,930 --> 00:02:22,380 Is the root device so wet, soft is rotating on. 25 00:02:23,470 --> 00:02:31,690 And the South is a with the will to direct or through some transmission arrangement, so. 26 00:02:32,780 --> 00:02:42,140 The soft of the mortar is connected and responsible for the rotation of will and the intention for their 27 00:02:42,140 --> 00:02:51,590 love and the will is responsible for the motion of the vehicle and that force multiplied by the radius 28 00:02:51,800 --> 00:02:52,600 of the will. 29 00:02:52,850 --> 00:02:54,590 It's called the dark. 30 00:02:54,590 --> 00:03:04,940 So that effective torque which result in movement or the displacement or speed of the vehicle. 31 00:03:05,600 --> 00:03:11,980 So we can say that electrical motor output is dark, that dark is applied to the vehicle. 32 00:03:12,200 --> 00:03:14,060 The vehicle is the linear device. 33 00:03:14,060 --> 00:03:15,470 It is moving linearly. 34 00:03:15,740 --> 00:03:22,970 But the electric motor that already weighs when the target generator at the start, which result in 35 00:03:23,240 --> 00:03:24,610 rotation up, will end. 36 00:03:25,010 --> 00:03:30,450 And this talk and this tangential force will result in linear motion of the vehicle. 37 00:03:30,950 --> 00:03:38,810 So although this all parts are internally, internally within the vehicle, but for the simplicity to 38 00:03:38,810 --> 00:03:47,360 simplify the understanding, we put this far apart from the vehicle that is all Pozza internally lit 39 00:03:47,360 --> 00:03:49,030 inside the vehicle. 40 00:03:49,310 --> 00:03:55,940 But what's happening and from that actual energy and force comes from where energy comes. 41 00:03:56,150 --> 00:04:02,410 Motor required the current to produce the dark and then current is drawn from the battery. 42 00:04:02,720 --> 00:04:07,910 So chemical energy of any battery is the basic source of energy. 43 00:04:08,180 --> 00:04:15,410 This chemical energy get converted into electrical energy and through the medium alpha magnetic medium. 44 00:04:15,590 --> 00:04:17,440 It is then converted into the force. 45 00:04:17,450 --> 00:04:20,150 So there are different magnetic loads of different motor. 46 00:04:20,150 --> 00:04:27,710 Whenever we put the current carrying conductor in magnetic field, it explains the fourth principle 47 00:04:27,710 --> 00:04:32,090 that is the magnetic principle attraction, repulsion. 48 00:04:32,720 --> 00:04:40,310 So each motor runner, either one or the principle, but it's required the current that need to be drawn 49 00:04:40,310 --> 00:04:42,910 from the battery according to the quick thought. 50 00:04:43,700 --> 00:04:52,430 So this is produced by the motor because of the current run by the battery and. 51 00:04:53,440 --> 00:05:01,540 So that we can see the electrical energy is converted into the mechanical energy and it is then converted 52 00:05:01,540 --> 00:05:09,880 into the linear motion, but we also require to control the speed and for the simplified arrangement. 53 00:05:10,870 --> 00:05:18,990 It is not written on an electric motor, but this block represents the electric motor drive that this 54 00:05:19,000 --> 00:05:26,830 block itself combine the convertors power converters that required to power the motor and to control 55 00:05:26,830 --> 00:05:28,700 the speed we require the controller. 56 00:05:28,990 --> 00:05:36,800 Also the electronic controller and converter all combined in this block of electric motor. 57 00:05:37,180 --> 00:05:42,530 And so we are having the speed control arrangement through the accelerator in the car. 58 00:05:42,940 --> 00:05:44,890 We can control the speed. 59 00:05:44,890 --> 00:05:53,230 We can accelerate the and control the amount of carbon that produced torque so we can control the amount 60 00:05:53,230 --> 00:06:00,490 of torque and so that it will control the amount of speed and displacement and acceleration and velocity. 61 00:06:02,050 --> 00:06:09,370 So this is the simplest way of electric vehicle and it is simplified block diagram gives the very basic 62 00:06:09,370 --> 00:06:17,060 idea about basically vehicle is nothing but mass and inertia and with the least friction. 63 00:06:18,240 --> 00:06:20,980 So in detail, we will discuss one by one. 64 00:06:21,340 --> 00:06:28,160 Later on we will discuss the vehicle and what different vehicle speed characteristics. 65 00:06:28,390 --> 00:06:37,060 And as it is the subject of engineering aspect, we will try to understand the vehicle instead of its 66 00:06:37,630 --> 00:06:44,650 basic form, how it can be represented by the thought speed characteristic saying we will also understand 67 00:06:44,650 --> 00:06:53,080 how electric motor can be represented by the speed characteristic and how combining a study automating 68 00:06:53,080 --> 00:06:59,980 this to task with characteristic, we can have a better idea about the performance, how one motor will 69 00:06:59,980 --> 00:07:06,210 perform to the parameters of the vehicle, and how can we achieve the desired performance. 70 00:07:06,520 --> 00:07:12,460 This all things will be discussed, but this is the simplified block diagram of electric vehicles that 71 00:07:12,460 --> 00:07:14,560 can be represented in this.
