Hybrid car. How It Works. Some Basics About Hybrid Cars

Hybrid Car

Let us first see how conventional and electric cars work. The conventional cars uses gasoline powered internal combustion engine which is and the car gets its all the power from this. An electric car gets its power from batteries. The Hybrid cars is one which can run on electric motors or gasoline powered engines or combination of both which creates higher mileage possibility.

The basic features of hybrid cars are:

Smaller engine:
The smaller engine provides enough power to car to run on free way but when the car needs to run uphill batteries comes to its rescue and the car runs on both batteries and gasoline engine. There is no effect in performance and driver could be unaware of the shift from battery to gasoline or vice versa.

Engine shutof:
When car puts brakes or when the car reaches red light the engine shuts down and car is powered by gasoline without driver knowing it

Efficiency:
The efficiency of the hybrid cars is achieved by
# Using lightweight materials for making body of car.
# Recovering energy and storing it in the battery
# Using advanced aerodynamics to reduce drag
# Using low-rolling resistance tires
# Engine shut off at redlight and when car pauses for a while.

Electric Car - History. Second Part

On 1971 the Lunar Rover was driven on the Moon, it was used electrical vehicle, because there is no oxygen to burn gas. Vehicle was developed by Boeing and Delco Electronics. Rover was driven by DC motor in each wheel with non-rechargeable batteries.

It seems that there was no chance to bring back electric car. But price of oil extremely increased in 70s and 80s. Consumers wanted to have car with minimal fuel cost fluctuation. Car companies again started to think about electric car motor and created prototypes. And in 1990 General Motor presented the GM Impact electric car concept and promised to sale electric cars widely.

The government agencies like U.S. Environmental Protection Agency impressed by impact electric car concept obliged car makers to reduce car emission and start to produce zero-emission cars like electrical vehicle. But unfortunately car companies made self-sabotages and tried press on agency using lobbyists and lawsuits, because producing of electric cars was not profitable comparing with gasoline analogues. U.S. Environmental Agency had to cancel car makers’ obligations.

Big car companies went out from electric car industry. Therefore new small companies were designing and producing electric car. The good example is Indian REVA electric car company, which sells its car mostly on Europe market.

Americans more like sport utility vehicles which are affordable only with low gas prices and car companies interested produce big cars, because they brings more money. But 2000s energy crisis again renewed interest in hybrid and electric car motors. Sport utility vehicle is not in favor today. Chevrolet Volt is hybrid car with ability to work on electricity and charge the batteries from gasoline engine was announced of the 2010 release. Also Nissan announced in 2009 Nissan Leaf midsize electric car, which can be available for sale in 2010.

Car Tires - How To Prolong Life



 
Paramount importance to ensure safety when driving a car has a condition of his tires. There are some "golden" rules under which you can achieve maximum mileage, increase safety and significantly extend the life of his tires.
 
1-e rule. Regularly check your tire pressure car. Because of the unequal pressure in the tires can be a bad handling car. In addition, uneven tire pressure can lead to uneven wear their protectors.




wear on outer edges

2-e rule. Need to regularly swap car tires. Thus, it is necessary every 5-10 thousand kilometers swap tires that are on the front wheels, the rear wheels. This procedure must be performed due to the fact that the tires on different axles of the car wear out in different ways. When moving the tires need to be sure to check the pressure in them.


3-e rule.Third rule. Need to check the installation of tires on rims in the direction of their rotation. This direction is usually indicated on the sides of tires. If you set the bus in the opposite direction, their characteristics are not optimal in all modes and conditions.

4-e rule. Drive the car to gently and quietly. For example, sudden braking and drifting on turning significantly reduce tire life. This is especially manifested in the studded tires.


5-e rule. In carrying out the replacement tire must pay attention to their deterioration. If this wear on the tires evenly, then it means that their working conditions are optimal. If there is uneven wear their protectors, you should always check the corners and the steering wheel to balancing on a service station.

What is Xenon?


It is known that more than half of accidents on the roads due to poor visibility. That's why quality lighting is one of the most important factors on the road to ensure safety and comfort.

How to achieve this increase in brightness? One possible option - to put additional or more powerful lights. Give it to us more light? Certainly willing, but it still gives an extra load on the generator due to greater consumption of electricity.


And, you can put a metal halide discharge (HID-Lamp), or, as they are called in the people - xenon light, which is 2-3 times brighter than a conventional halogen lamp, and power consumption almost in half below. The driver, using xenon in his car at night driving sees more clearly the details of the road, pedestrians, cyclists, counting on the roads, so, manages to keep up with the situation if necessary. The car, in turn, becomes more economical, by reducing the load on the generator, which in turn lowers fuel consumption.


What is a Xenon lamp? This lamp is composed of the bulb encasing a capsule with two electrodes, filled with xenon (an inert gas) with the addition of mercury salts. To get light, uses an electric charge of high intensity. First, the lamp is supplied a charge capacity of 25,000 volts to arc inside the lamp appeared. After the appearance of the lamp arc, is supply voltage of 80 volts.


Safety, comfort and prestige of xenon proved in theory and in practice, and it certainly makes him a leader in lighting technology on the roads.

Electric Car – Informed Decisions

An electric car uses an electric motor for propulsion and is the best known alternative to expensive gasoline driven vehicles.  The electric car motor makes use of electrical energy to produce mechanical energy, or in other words movement.  Electric motors make use of the electrical energy to rotate and anything attached to the motor automatically harnesses that rotating movement.  Electric motors are not only limited to cars, you can find the smallest ones in watches and the largest ones are used to propel ships.

The electric car motor involves rotating coils of wire driven by a magnetic force that is exerted by a magnetic field on electric current.  This is how electrical energy is transformed into mechanical energy.
The principle behind alternating current or the AC motor is that every single second it is changing direction of the flow several times.  For this reason the current that runs through the electromagnet is AC, with the north and south poles on the electromagnet alternating as well.  This keeps the electromagnet spinning.

The DC electric car motor is actually a very good one and the Advanced Series is a best seller.  However you will need to consider the following carefully before you opt for a DC motor for your car.  Will you need to carry heavy loads and go up hill frequently?  If the answer to both is yes, then you will be better off choosing an electric AC motor.

If on the other hand these are not really important concerns, then a DC motor will be a good choice.  They provide very good torque right from the start and give the driver a good smooth ride.

Remember that with the electric car motor you definitely get what you pay for, so research well and seek the advice of a professional before you make a final decision.  Electric motors are not cheap and you cannot just go out and buy another if you make a mistake, it will prove to be a very costly mistake!

Electric Car Parts


 Have you had enough of exorbitant gasoline bills? Is a good part of your monthly paycheck going towards fuel costs? Would you like to change to an electric car that will give you virtually zero gas bills and contribute to a cleaner environment? If the answers are yes all the way, read on to find out all you need to know about the electric car parts you are going to need to convert your normal car to an electric one.

You should always buy your electric car parts from a reputable dealer; never go for used parts, they do not come with any sort of guarantee. Make sure your dealer is licensed and will give you a guarantee on the parts you buy. Also make sure there is a good return policy in place, should you wish to return a part for whatever reason.

In order to get an electric car you can either convert your existing car or buy a new, ready made electric car. In either case you need to know something about the electric car parts to make an informed decision about your purchase.

Your battery charger is one of the most important items; you will need to charge your car everyday and poor quality battery chargers can make life very difficult for you.

• The car battery pack has to be the best; your options include the common and affordable lead acid flooded type batteries; Absorption Glass Mat (AGM), which are maintenance free, more powerful and of course a bit more expensive; the Ni-MH is a maintenance free, very expensive battery but very long lasting than any of the others.


• The motor is the next important car part; this is the determining factor for the vehicle’s performance. The motor you buy should be technically sound, excellent quality and capable of high performance output.Apart from these main electric car parts there are several others and it would be a good idea to take a professional with you when you plan to convert or buy.

Electric Car Parts – Everything You Need To Know

The electric carriage requires three electric car parts to drive: a motor at powered an automobile, batteries that storage energy, motor’s controller that brings and control electricity from batteries to engine. The driver manages speed of car using accelerator connected with motor’s controller through potentiometer (resistor with variable resistance). Controller brings required level of power depending on what position driver sticks pedal of accelerator.

Controller uses pulsing principle to regulate the power on the engine. It means that when driver pushes accelerator pedal controller gets level of voltage on potentiometer. Depending on this level controller cuts the power from accumulator batteries and brings these portions to the engine. Let’s assume that driver pushes pedal on 30%.

Controller reads this level from potentiometer and cut power with equal portions (impulses) for example 20 thousand times per second.  So 6 thousand impulses have maximum voltage level, 14 thousand have zero level. After second controller again reads voltage level from potentiometer and calculates the number of impulses.

The number of impulses per second is important criteria for controller because impulse frequency causes the same engine vibration frequency. As human hearing frequency threshold is 15 thousand per second. So when impulse frequency is more than 15 thousand per second it keeps silent engine work for human.
DC controller works using principle described above. AC controller is much more complicated.

Because it produces three phase alternating current from batteries’ direct current. So it uses impulse principle for pulse the current and also it reverses polarity of the voltage 60 times per second using set of transistors.
As you see AC motors and controllers are more complicated for installation during electric vehicle conversion than DC motor, but they produce more power comparing with the same weight as DC engines.

Electric Car Motor – What To Look For

An electric car motor functions by using electrical energy to create mechanical energy.  You can run your electric motor as a generator but this is not recommended.  The electric motor can be powered by direct current (DC) from a battery powered device or by alternating current (AC) from an electrical distribution grid.  Increasingly advanced electric motors were created all through the nineteenth century.

When it comes to buying an electric car motor you need to invest in a really good one; this is one of the most important parts of your electric car.  When planning to convert your existing car to an electric one, do your homework well to find the best and most suitable electric motor for your car.  What you will need to take into consideration apart from pricing is whether the motor will be suitable for your car, the load it has to bear and the ground it has to traverse.  The motor you buy has to be a versatile one, that is powerful enough to give you high quality constant performance irrespective of driving conditions.

Another aspect of the motor that you will need to consider is whether to choose an AC or DC motor.  Your choice will have a direct impact on the cost and performance.  You can get some really affordable and fairly decent DC motors, but they falter when going uphill, cannot provide you with constant power and are just plain not suitable for carrying heavy loads.  If none of these factors are of any concern to you then by all means go for a DC electric car motor.  The Advanced DC Series wound motor is actually one of the best selling electric motors and provides excellent torque from the very outset.

The 3 phase induction AC motor is probably the most expensive and also the best.  The ultimate decision is yours; you need to choose what you think will best suit your needs and your budget.

This article would be incomplete without a rundown of the benefits of making use of one of these electric car kits to convert your car to an electric car.

• Benefit number one is your gas bill drops down to ground zero
• Engine life is extended and performance enhanced
• You get an IRS refund for ‘technically going green’
• You are making your contribution to the environment by reducing greenhouse gas emissions considerably
• The cost of driving an electric car is only a few cents to a mile and refueling can be done anywhere there is an electrical outlet.
• No more oil, coolant and filter changes

Using electric car kits, almost any vehicle can be converted to an electric one. Electrical power is provided through a battery pack and you will need to install an electric engine beside the gas powered one, which can be rather pricey. However, when you consider the long terms savings on gas, it is well worth the cost.
