1 00:00:01,430 --> 00:00:04,130 Let's discuss about the electrical engineering. 2 00:00:06,610 --> 00:00:14,560 Electric vehicle engineering is not a single disciplinary are really quite the multidisciplinary engineers 3 00:00:14,740 --> 00:00:23,050 to build the electric vehicle, so specialist in the area of engineering must work together to build 4 00:00:23,050 --> 00:00:24,070 electric vehicles. 5 00:00:25,200 --> 00:00:33,780 We require electrical engineer, electronics engineers, mechanical engineers, chemical engineers and 6 00:00:34,470 --> 00:00:41,380 mainstream automobile engineers, as well as for the Mordini with software engineers, are also required. 7 00:00:42,270 --> 00:00:50,160 So this course is basically for this all engineers and those who want to understand the fundamentals 8 00:00:50,160 --> 00:00:51,700 of electrical engineering. 9 00:00:52,200 --> 00:00:59,610 So when any project like this, all team members, this all specialists should work together to set 10 00:00:59,610 --> 00:01:00,630 and define the goals. 11 00:01:00,630 --> 00:01:05,430 And Latrun, they can focus on that particular area. 12 00:01:05,790 --> 00:01:13,440 So if we discuss about the path of electric vehicle system, not only we can, but we are discussing 13 00:01:13,440 --> 00:01:16,560 the part of electric vehicle system. 14 00:01:17,280 --> 00:01:22,380 And first comes the vehicle characteristics and its requirement. 15 00:01:23,580 --> 00:01:24,000 So. 16 00:01:25,140 --> 00:01:34,590 In this case, when we start any electric project, all engineers from all disciplines must work together 17 00:01:34,590 --> 00:01:42,560 as a team and to understand what is the requirement of an electric vehicle that we are going to build, 18 00:01:42,900 --> 00:01:49,920 that means vehicle characteristics in terms of it, maybe project on the God project on the truck and 19 00:01:49,920 --> 00:01:56,070 different characteristics may be required different and goals need to set during the initial stage. 20 00:01:56,340 --> 00:02:06,990 So all of these things need to be done in this operation of all the engineers from all the disciplines 21 00:02:07,260 --> 00:02:09,610 later on, what can be segregated. 22 00:02:09,930 --> 00:02:12,630 So we will discuss about this fight between. 23 00:02:14,580 --> 00:02:24,210 In succeeding session, the next artist body supported, then it was the dynamics and this all calculations 24 00:02:24,560 --> 00:02:32,360 also involved the safety standard, maintaining the CGI, depending upon the requirement that each engineer 25 00:02:32,360 --> 00:02:38,850 said their role to fulfill the basic requirements and outcome of the vehicle. 26 00:02:39,440 --> 00:02:46,940 So the engineer must be aware, very well aware about the vehicle characteristic and its requirement 27 00:02:46,940 --> 00:02:48,890 for that particular project. 28 00:02:48,920 --> 00:02:56,660 So when obviously mechanical engineer or automobile engineer will do the work of body design, but in 29 00:02:56,660 --> 00:03:06,520 line with the requirements for the project, electric motor via this combination of electric motor can 30 00:03:06,800 --> 00:03:14,510 work up and electronic control, so also to maintain order to achieve the requirements and goals of 31 00:03:14,510 --> 00:03:16,760 the vehicle characteristics. 32 00:03:17,420 --> 00:03:25,820 Electrical engineering or electronics or electric engineer combined can do this job for selecting, 33 00:03:25,820 --> 00:03:33,170 designing and engineering aspect of electric motor race drive, matching the characteristics and all 34 00:03:33,170 --> 00:03:34,050 these comes. 35 00:03:34,190 --> 00:03:37,370 We are going to discuss it one by one. 36 00:03:37,370 --> 00:03:42,000 Latrun Electrical and electronics engineer role. 37 00:03:42,020 --> 00:03:42,890 All is major. 38 00:03:44,790 --> 00:03:55,140 Then badly, so badly, they had different topologies scrollable in the batteries, not only the type 39 00:03:55,140 --> 00:04:00,660 of batteries, but in the lithium and also different chemistry software that I will always need to consider. 40 00:04:00,900 --> 00:04:08,580 And research is also going on for the battery to improve our density, energy density as well as its 41 00:04:10,920 --> 00:04:11,920 weight density. 42 00:04:12,360 --> 00:04:19,920 So this characteristics of batteries to improve its range for more reliability, for improved the safety 43 00:04:19,920 --> 00:04:20,450 features. 44 00:04:20,460 --> 00:04:30,390 So lots of research going on and the chemical engineering involved in this fight for selection and for 45 00:04:30,390 --> 00:04:33,650 the future scope of the batteries. 46 00:04:34,590 --> 00:04:42,120 It's also included a battery management system for the safety in different aspects of electronics, 47 00:04:42,120 --> 00:04:48,260 electrical engineering and also involved in the system when it comes. 48 00:04:52,850 --> 00:04:59,480 Then the regular part is the transmission system, if it is not a direct drive, the selection of plasma 49 00:04:59,480 --> 00:05:04,180 system is akin to five thousand nuclear engineer or the mechanical engineer. 50 00:05:04,490 --> 00:05:12,380 One need to assure the efficiency and quality of the transmission system from the prior to the will 51 00:05:12,920 --> 00:05:16,260 depend upon the topology and requirements of the character. 52 00:05:16,770 --> 00:05:20,070 This is very important, very characteristic and requirement. 53 00:05:20,090 --> 00:05:25,640 There may be certain goals that need to be achieved by the team leader. 54 00:05:25,640 --> 00:05:32,210 And in line with this goal, each engineer will work and focus on that particular area. 55 00:05:32,480 --> 00:05:37,790 The transmission system will be fulfilled by the mechanical as well as engineer. 56 00:05:40,490 --> 00:05:46,220 The communication and diagnosis, this is very important part again, so, you know, the guard has 57 00:05:46,250 --> 00:05:56,020 a different communication system, can buscombe communication and the communication is basically there 58 00:05:56,210 --> 00:06:03,040 a different number of microcontroller and chips that are available in the event defanging pacemaker 59 00:06:03,710 --> 00:06:07,880 and an electric motor drive because there are a number of sensors available. 60 00:06:08,270 --> 00:06:18,050 So to communicate with each other and to communication or establish communication between the different 61 00:06:18,050 --> 00:06:25,670 parts of the controller, the communication bus is required and to take the safety feature in a runtime 62 00:06:25,670 --> 00:06:35,360 data related to health monitoring of the different systems are used for the diagnosis purposes. 63 00:06:35,720 --> 00:06:45,620 So electronics and communication engineer can lead this role here to design the communication bus and 64 00:06:45,620 --> 00:06:53,570 for the automobile system and to ensure the diagnosis and proper communication. 65 00:06:53,870 --> 00:07:01,430 Now one more thing is generally added in the modern electric vehicle system that are the autonomous 66 00:07:01,430 --> 00:07:05,980 system and in vehicles between vehicle communication. 67 00:07:06,380 --> 00:07:13,840 So nowadays it is also a growing trend to make communication available between two vehicles and to share 68 00:07:14,420 --> 00:07:19,100 a location and different system with each other. 69 00:07:19,400 --> 00:07:23,620 The one there is no communication is added between the battery and charging system. 70 00:07:23,900 --> 00:07:31,160 So because batteries of different voltage and current capacity is not available, so certain things 71 00:07:31,160 --> 00:07:37,760 need to be communicated between the battery and the public charging station to ensure the safety and 72 00:07:37,760 --> 00:07:42,810 the level amount of current that is for charging the batteries. 73 00:07:43,220 --> 00:07:49,910 So there are different rules for the communication and diagnosis from the electronics and communication 74 00:07:49,910 --> 00:07:50,640 engines. 75 00:07:55,450 --> 00:08:02,560 So charging system and infrastructure is a great tool of power in our power system, engineering or 76 00:08:02,620 --> 00:08:10,630 electrical engineers to establish and to ensure the charging infrastructure, as well as the charging 77 00:08:10,630 --> 00:08:17,920 system for the high power and the fast charging system, availability and reliability and different 78 00:08:17,920 --> 00:08:18,620 standards. 79 00:08:18,620 --> 00:08:27,180 So electrical and our system engineer need to work on the charging system and infrastructure design. 80 00:08:27,460 --> 00:08:33,520 So this is why this is called combined electric vehicle system and part of electric vehicle system. 81 00:08:33,970 --> 00:08:42,730 So different engineers need to work on certain specific area to achieve the one goal and to achieve 82 00:08:43,570 --> 00:08:49,640 the basic requirement of the electric connectors.
