Tesla's model S: Secret unveiled: A brief technical inspection

We all know that how Tesla's Model S is being too popular among the people of US, Canada and other countries but still many people don't know the proper reason behind the technical reasons so we are now going to look deeply into Tesla's battery system, power drive, gearbox, extra usable space, Wheel Drive, Security and other extra features.

Here is the first thing that Tesla introduced The battery system, not by using a huge battery pack system but instead of it they use small battery cells in series and parallel which are quite too many to arrange it.

The main advantage of the small battery system is there is no extra loss of heat during the drive went to cells are in proper working condition. It is the mean this advantage of use battery system that heats up more when the battery is in full working Tesla introduced a new system to avoid extra heat from the battery back to install a coolant system between the path of series and parallel system.this may help a car system to remain cool during full working condition and to work efficiently for longer Time than forecasted. Both systems give same power but the small better system is too easy for handling and there are no further issues of heating anymore. 

The second thing is the power Drive approximately 100 years ago Nicola Tesla invented is AC power drive which is generally called synchronous motor.  to convert DC's power into AC there should be an inverter so Tesla introduced a combined power drive system which contains an inverter and a synchronous motor we all know that too very the speed of synchronous motor there should be a change in frequency of AC power. Which can easily be provided by inverter by the higher frequency of AC power they should be a higher rotation of output shaft of the synchronous motor not only because of this combined power drive system there is no need for gearbox system. The Accelerator is directly connected with inverter through a microchip which controls the frequency of AC power from the small battery pack system. 

In engine power-driven vehicles it is the main disadvantage that System cannot go further limit of RPM like 2000 to 4000 RPM. But in the case of the inverter and synchronous motor combined system we can go to 17 to 18000 rpm in short range of time. There is no gearbox so the friction loss is not their overall the total power can directly transmitted by the power system. 

so that it can be also helpful for overall efficiency when the weight of the car is too low when the gearbox and the engine is absent. In addition to that, we have more extra space for usability. 

The third one Tesla used simple open differential system instead of highly complicated slip differential system.  the main reason behind using open differential system is it can transmit more torque then slip differential system. The traction control problem can be controlled by selecting backing and cutting the power supply. Weather in IC Engine cutting the power supply is not too responsive for traction control problem.  In this system, the power supply rate is highly responsible by using controllers and algorithms.  They just replace the large complicated system into a smart software.

It used the single speed transmission system that transfers the power by two steps. It is much is here to reverse the. The vehicle by only changing the face of induction motor the RMF changes into opposite direction and as an output drive will rotate in reverse direction.
In addition, regenerative breaking system is too useful. it means that RGB saves the K.E. of the car into electricity. In such case the same induction motor works as a generator, here will drive is the induction motor and Powell stored back to the battery pack.

These are the main reason that Tesla's Model S is more efficient than any other IC engine powered vehicle.

Rolls-Royce : Top Unknown facts about luxury car manufacturer : You must know

Some interesting facts about Rolls-Royce:

We all know that the market value of Rolls- Royal is much more than any normal automotive because of the higher luxurious interior and exotic outlook with the Black horse performance and much more.....

  • The first 10 HP Rolls-Royce was sold for $395 today it works over two lakh and 50,000.
  • More than 60 out of 10 Rolls-Royce motor cars built are still Road wordy which is too good for Rolls-Royce to be in the market.
  • Most of us don't know that the Rolls-Royce radiator grille is entirely made by hand and inspect by eye. There are no measuring instruments are used for radiator grill. 
  • Approximately it takes one man one day to make grill or radiator and then total five hours are spent to repolishing it.
  • The Rolls-Royce radiator was the only one that does not recognize as a trademark until 1974.
  • Actually, Rolls-Royce made rifles during the First World War. 
  • It takes over 800 main powers to make a complete body of phantom 5.
  • Rolls-Royce is the only one manufacturer that engine is completely made by hand and even today latest models of Rolls-Royce engine is entirely made by Humans. 
  • It's shocking that the cooling capacity of the air-conditioning system in the silver spirit is the same is 30 domestic refrigerators.
  • before the world war Rolls-Royce did not make a complete car but the only chassis. The body is being added by outer coachbuilders.
  • It was a time when Rolls-Royce engine makes world records in speed in the air on the land and on the water Simultaneously.
  • there are total 27 electric motors used in every Silver Spirit. Each glass of the spirit is given a final polish with the fine grain  Pumice which is generally used for polishing optical lenses.
  • The hydraulic tappers on Rolls-Royce motor car are given a natural finish of 16th million of an inch.

Top 10 Vehicle Safety Devices

If you are purchasing a new vehicle, make sure that it has as many of these safety devices as possible, to ensure the safety of you and your loved ones. It may cost a little bit extra, but it is definitely worth it if these things are going to save lives.

There are many other new safety devices that are helping to keep people safe while they are on the roads.

Sometimes, we wonder if technology is hurting more than helping us, and in some cases, it may be. One way that today's technology is really helping us is by providing us with many more devices in our vehicles to keep us safe. Throughout the history of motor vehicles, there have been some significant changes. For instance, in the beginning, vehicles didn't even have seatbelts or windshield wipers. We have come a long way since Henry Ford first started rolling cars off the assembly line. Today's automobiles have all kinds of wonderful features designed to keep you and your loved ones safe.

Here are 10 of the top vehicle safety devices you need to be aware of, especially when purchasing a 
 new vehicle:

Top 10 Vehicle Safety Devices

[1] Airbags

Some people think that these are actually dangerous, but they have in fact saved many, many lives. There are two main types of air bags, dual stage airbags and side airbags. If needed, the dual stage airbags will go off at different times, one in a minor accident and both in a more serious crash. Side airbags help to prevent drivers and passengers from getting head injuries. Small children should be in their car seats, in the back seat of your vehicle, where there are no airbags that can actually injure them rather than save their lives.

[2] On/Off Switches

Many vehicles are equipped with on/off switches for airbags. This is for the times when children are going to be sitting near them. There have been many instances of airbags injuring children, and you can eliminate this risk by using the switch. There have been many incidents of injuries and even death in small children because of airbags, and this switch will eliminate that problem.

[3] Passenger Sensing System

This has been created to reduce injuries or death to smaller children. This is an advanced airbag system that can tell the size of the person in the seat, with sensors that get information about the front-seat passenger's weight and the pressure on the seat. This information tells the airbags whether or not to go off in the event of a frontal crash.

[4] Energy-Absorbing Steering System

This is designed so that it will compress upon impact, lessening the risk of rib injuries to drivers. This has been proven to work in many instances, and it has reduced the risk of driver fatalities by 12%, and serious injuries and death risks have been reduced by 38%. When there is a crash, drivers are often thrown forward, and the steering wheel can cause serious injuries, making this feature one that you should look for in your next vehicle.

[5] Back Up Sensing System

This is a wonderful little invention that makes it so that when you are backing up, you will be warned if you get too close to another vehicle or other object. This is now an option on a number of larger vehicles, such as RV's and SUV's, and it has greatly reduced the number of collisions caused by backing up, and a lot of bicycles in driveways have been saved because of this feature.

[6] Electrochromatic Mirror/Auto Dimming Mirrors

One thing that can really be annoying when you are driving at night is the reflection of headlights in your mirrors. This feature will automatically darken the mirrors, which in turn reduces the glare. Today, approximately 10% of all vehicles are equipped with this feature, and many more vehicles are expected to have this technology in the near future. This not only helps to prevent accidents, it also helps people who are extremely light sensitive, and bothered by lights in their mirrors.


[7] Head Restraints

Two of the most common injuries that occur due to automobile accidents are head injuries and whiplash. These head restraints, which are on the top of the front seats, will help to hold the head in place, and they reduce these types of injuries. New and more advanced systems make it so the seat will move down and back in the event of a collision, so there will not be as much forward motion, which of course will lessen the risk of head and neck injuries.

[8] Heads Up Display

One should never take their eyes off the road while they are driving, but we all do. We must look down to check our speed and other things, and it can only take a split second for an accident to occur. A heads up display (HUD) will put the information you need right across your windshield, so your eyes never have to look anywhere but at the road. You will still be able to watch what you are doing, while being able to find the information you need quickly and easily.

[9] Padded Knee Bolster

Knee injuries are a common result of automobile accidents, and this device can greatly reduce the risk of this type of injury. This is another feature that can keep the driver or passengers in the proper position to lessen their chances of being injured. It will also help to keep passengers from sliding beneath the instrument panel and risking becoming trapped or injured even further.

[10] Seatbelts

These may have been around for many years, but many advancements have been made so that they will protect automobile occupants even more than the older versions. Unlike in the past, where seatbelts just went around your waist, today's vehicles are equipped with front and rear seat belts for both the lap and shoulders, and the locking system insures that those wearing the seat belts (which is the law in Canada and the US) will not be thrown forward if an accident occurs.
