Electric Vehicles

Nowadays people have more varied choices in buying vehicles and cars. As now they have the option of electric vehicles. But what exactly electric vehicle is? In simple words an electric vehicle, or EV, is a vehicle with one or more electric motors for propulsion. Thus, the motion may be provided either by wheels or propellers driven by rotary motors, or in the case of tracked vehicles, by linear motors.

The energy used to propel these kind of can be obtained from various sources such as:

1. From chemical energy stored on the vehicle in on-board batteries: Battery electric vehicle

2. From both an on-board rechargeable energy storage system (RESS) and fueled propulsion power source: hybrid vehicle

3. Generated on-board using a combustion engine, as in a diesel-electric locomotive

4. Generated on-board using a fuel cell: fuel cell vehicle

5. Generated on-board using nuclear energy, on nuclear submarines and aircraft carriers

6. From more esoteric sources such as flywheels, wind and solar

7. From a direct connection to land-based generation plants, as is common in electric trains and trolley buses

Electric vehicles generally use electric motors used to drive vehicles because they can be finely controlled, they deliver power efficiently and they are mechanically very simple. Moreover these electric motors often achieve 90% conversion efficiency over the full range of speeds and power output and can be precisely controlled. Thus it won’t be wrong to say that these electric motors can provide high torque while an electric vehicle is stopped, unlike internal combustion engines, and do not need gears to match power curves.

These days electric vehicle is designed in two ways those are Battery Electric Vehicles and Hybrid vehicles. Battery Electric Vehicles covert chemical energy to electrical energy in batteries; whereas Hybrid vehicles, which convert chemical energy to electrical energy via an internal combustion engine and a generator. However, there is another less established form of electric vehicle which is the ‘plug-in hybrid’. This ‘plug-in hybrid’ attempts to combine the benefits of both these designs and allows the moderate capacity batteries of a hybrid vehicle to be recharged not only from the internal combustion engine and generator.

Electric Vehicles include electric wheelchairs, the Segway HT, electric motorcycles and scooters, motorized bicycles, golf carts and neighborhood electric vehicles. Furthermore some working electric vehicles include heavy work equipment, fork lifts, and numerous other service and support vehicles. Thus, if you are an environment conscious then electric vehicle is best for you.

Electrifying Facts on Electric Vehicle Conversion – All You Need to Know

Right now, with the gas at prices that we have never seen before, many people are looking for ways to cut down on gas consumption and there are some people who are looking at ways to avoid using gas at all. They are researching electric vehicle conversion which is converting a car or small truck to run on electricity instead of gas. There are many benefits to having vehicle that runs on just electric but an electric vehicle conversion is no simple task. The benefits for the vehicle are, smooth running, low maintenance, low vibration, economical, and totally convenient. An electric vehicle conversion is complicated. As well as no longer using gas the vehicle will no longer use oil, an exhaust, belts, hoses, water pump, coolant, radiator, spark plugs, plug wires, and injectors. So this is not a job that should be undertaken by an amateur.

If you are a mechanic who knows what they are doing, the electric vehicle conversion can be done in your own garage, with few specialist tools. The materials needed for the electric vehicle conversion is of course the electric motor, the motor mount, motor controller, speed controller, system control box, high current shunt, high current fuse, high current circuit breaker, current meter, voltmeter, clutch plate hub adapter, main battery bank, 12V battery charger, 6V golf cart batteries (common choice), battery rack, cable terminal lugs, along with a vacuum pump and switch kit for the brakes.

Other materials for the electric vehicle conversion will include any kind of framework that you would want to use to house the batteries that are needed to run the vehicle. Cars that are most commonly used used in electric vehicle conversion are the Chevy S10, Dodge Colt, Daytona Ford Escort, Porsche 914, Honda Civic, Mazda B2000 pickup, Datsun pickup, Plymouth Sundance, Pontiac Fiero, Suzuki Samurai, Toyota pickup, and Volkswagen Beetles.

The cost of the electric vehicle conversion will vary and depend greatly on the vehicle that is going to be converted. This can range from $6500 and $9500 dollars and that estimate does not include the cost of the vehicle itself.

Depending on the size of the vehicle and the number of batteries that are used in the conversion, the distance the vehicle can drive on one charge will vary accordingly. The general Chevy S10 which has 16 six-volt batteries and weighs a total of 3700 pounds, will go about 35 miles on a full charge. If you have more batteries on a lighter car, then you will be able to go much further on a single charge.

The weight of the vehicle will also factor on how fast the vehicle will be able to go. The lighter the car and more batteries, the faster it can go. Historically electrically converted cars were slow but now they can achieve speeds of 60 to 80 mph.

Deciding on whether this option is right for you really depends on your mileage, how long you intend to keep you vehicle, and of course your commitment to the environment. Hopefully i’ve sparked enough interest for you to want to find out more.

Hybrid Electric Vehicle – Down to the Parts

With all the great news from the auto industry introducing another hybrid vehicle or another electric vehicle, this article explores a bit what such vehicles are made of. What are the differences with the conventional petrol car and what might the future hold for them?

The first difference you see these days is that both the electric vehicle and the hybrid vehicle come with a plug to charge it at home; the conventional vehicle has not. The conventional vehicle also has no electric engine to power the wheels or a large battery to power this engine. The conventional car of course does have a battery, but that is just used for starting the internal combustion engine and it acts as a buffer for the electrical systems used. Power in the conventional vehicle is generated by the combustion engine.

For an electric vehicle, there are two main components: the electric motor and the battery. The electric motor is the one to power the wheels of the vehicle and the battery is used to bring along energy for the trip. They almost all have the option of regenerative braking, which allows one to recover energy when slowing down and charging the battery a little while doing so. This is a great method to increase the overall efficiency for a vehicle! Further more there is often a special battery management system (BMS) which ensures the battery is kept at the right temperature and is not charged or discharged in a way that can damage the battery.

For a hybrid vehicle there are a few more main components: besides the electric motor and the battery, there is also an onboard power source like the conventional combustion engine (but also a fuel cell is used for example). Additionally, there is a system that somehow connects the power from the battery and the for example combustion engine and gets it to the wheels. There are many ways to do this last step, the simplest being that the combustion engine would be used as a generator to power the electric motor with electricity. Excess electricity is stored in the battery for future use. Another method is to have a special gear set combine the mechanical power from the combustion engine and the electric engine and get them to the wheels. There are also manufacturers who power one set of wheels with the combustion engine and the other set of wheels with the electric engine. A big advantage of the hybrid vehicle is that it can use the very efficient electric engine at lower speeds (for example urban areas) and the combustion engine for extra power on the highways or for extra range.

To sum it up, an electric vehicle consists of:

– Electric Engine
– Battery

A hybrid vehicle consists of:

– Electric Engine
– Battery
– Energy source (internal combustion engine, fuel cell, etc)

The disadvantages of the electric vehicle and the hybrid are mostly the cost. Compared to the conventional car they can cost more to purchase. This has two main reasons; the first being that the conventional car is mass-manufactured which makes it cheaper (compare one million units produces versus one thousand units produced) and the second is the current price of batteries. Batteries at the moment are the biggest cost within the vehicle, the larger your battery is, the larger the cost is in the total price of the vehicle.

Another disadvantage which currently mostly applies to the electric vehicle, is the range it can cover. Current vehicles are of such a weight and their batteries can only hold a certain amount of power. Comparing the electric vehicle to a conventional petrol car they can cover a lot less ground on a full charge or tank. The first argument to counter this disadvantage is that most people do not drive distances that can not be covered by an electric vehicle. Current electric vehicles can cover about double or four times the daily distance required by many people! However, there are three movements currently helping to overcome the range anxiety problem. The first is the battery manufacturer, which improves the technology so that the battery will weigh less and can contain more power. The second is the charging industry, where solutions are found in fast charging. Conventional charging can take up to eight hours to charge your vehicle. The goal is to reduce this to an acceptable amount of mere minutes. The third force is heading for battery swapping; much like a petrol station, an electric vehicle can swap the empty battery for a fully charged one.

For the future of the electric vehicle and the hybrid there are many options, the most popular ones are:

– Fuel Cells
– Fast Charging of batteries
– Better batteries that weigh less and hold more power
– Battery swapping stations
– New car design options

Lots to expect from the electric vehicle and the hybrid vehicle!
