do electric cars have an alternator

by Conner Huels Published 4 years ago Updated 3 years ago

Electric cars don't have alternators for two good reasons:
In gas cars they get it from mechanical power, which is supplied by running the engine and burning fuel. EVs don't have engines, so an alternator would be lacking its power source.

How long does it take alternator to charge battery?

When your car engine runs, your car alternator may take more or less half-hour to recharge the battery fully. Again on a messy road, it takes relatively one hour. (In a crowdie road, your car will run slowly) And if the engine is in idle stage, your car alternator will take more than one hour to charge the car battery.

Do electric cars use alternator?

Electric vehicles and hybrids don't have an alternator. Instead, they have a DC-to-DC converter that recharges the 12-volt battery using power from the high-voltage battery pack (the “traction battery”) that powers the vehicle.Apr 25, 2021

Is there an alternator in a Tesla?

Electric cars like Tesla don't have alternators. Instead, they have DC to DC converters that power the 12v battery. Thus electric cars don't need to have an alternator. Understanding why electric cars don't have an alternator can be confusing.Jan 15, 2022

Can an electric car charge while driving?

Drivers of electric vehicles should be able to charge their car in the future while they are driving. This shall be enabled via inductive charging. Hereby, alternating current generates a magnetic field within a charging plate, which induces the current into the vehicle.

Do electric cars have a generator?

Key Components of an All-Electric Car Electric traction motor: Using power from the traction battery pack, this motor drives the vehicle's wheels. Some vehicles use motor generators that perform both the drive and regeneration functions.

Is there an electric car that charges itself?

The energy is used to recharge the car's battery. But this is only self-charging on a small level. However, there is actually a German company called Sono Motors, which is working on a car that self-charges itself through solar power.Jan 25, 2022

How Far Can electric cars go on a single charge?

250 milesFull-electric BEVs today have an average range of 250 miles on a single charge. However, newer models from marquee companies like Tesla and Mercedes can go as far as 600 miles in one charge. Hybrid electric vehicles (HEVs) have an electric motor, battery, a gasoline tank, and an internal combustion engine.Mar 17, 2022

Why don't electric cars have solar panels?

Electric cars do not have solar panels because when solar panels are on cars, they are only converting 15%-20% of the energy from the sun. The solar panels would only give about 3 miles of energy in one hour of charging. This is very inefficient and currently doesn't make sense to use on electric cars yet.

How much does it cost to charge the average electric vehicle?

While electricity costs vary, the average price in California is about 18 cents per kilowatt hour (kWh). At this price, charging an electric car such as the Nissan LEAF with a 40-kWh battery with a 150-mile range would cost about $7 to fully charge.

How do electric vehicles charge their batteries?

The question of technology is to be reasoned at most when addressing how electric vehicles charge their batteries.

Do EV’s recharge while driving?

There a various gist about charging solutions of electric cars that have been widely spread over the internet and social media.

Do Electric Cars Have Alternators?

In short, The simple answer is No. Electric vehicles do not have alternators as much as they don’t need them. E.V.s, the internal combustion engines are replaced with electric motors. And, the purpose of the alternator is to keep the 12-volt battery charged.

What is the energy that powers an alternator?

Remember, the ENERGY that powers the alternator is actually the mechanical energy created by the engine through combustion of fossil fuel. An electric car doesn't have an engine or gas/diesel fuel. We COULD use the battery to spin the motor to spin the alternator to generate electricity.

Do electric cars have alternators?

In reality, what electric cars do have is regenerative braking, where the motors switch to generator mode and uses the kinetic energy of the car to recharge the batteries, slowing the car down in the process. No electric cars use an additional alternator.

Can I recharge a lithium battery from an alternator?

Can I recharge my lithium battery from my vehicle alternator? – Yes, but not necessarily to full charge, due to the fact that most Alternators are adjusted for the lower voltage requirements of the vehicle Lead/Acid Battery (approximately 13.9-Volts). Lithium Batteries require 14.4 to 14.6-Volts to fully charge.

What is an alternator that is not attached to a gas engine?

An alternator which is not attached to a gas engine won't produce electricity. Pierce Arrow 1931 Nickola Tesla conversion. Tesla electric car was a converted Pierce-Arrow, from 1931 ..In place of the engine, there was an AC motor. This measured a little more than 3 feet long, and a little more than 2 feet in diameter.

Where does energy come from in an electric car?

To get down the road, SOMETHING has to provide the energy to do the work of turning the wheels; if it's an electric car, the batteries provide stored energy from the grid (or your solar panels) to turn those wheels...but the energy has to come from somewhere.

How to increase range of car?

You could use the alternator to increase the range of your car by hooking it up to the battery and motor system. Therefore reducing the load on the batteries. This would increase your range but not get an equal system.

Is an alternator 100% efficient?

Perpetual motion is impossible. An alternator is not 100% efficient -- it produces less power than it takes to run it.

Can alternators be charged at home?

The batteries can be charge at home for the initial boost, but after that an alternator can be connected to the electric motor and every time it runs it should power the alternator that will provide charge as the car drive. There is more than one way to power the alternator, for instance the drive shaft have to rotate when the car runs, that rotating power can be connected to something else. I will try it myself if I had the $$$$ means and proper location (shop)

Can an alternator power a car?

An alternator for sure cannot by itself power a car but through batteries to release that needed extra power. i have a model, perhaps you can picture this: an alternator is connected to a motor which is connected to the wheels. The alternator is further connected to a set of batteries for charging.

Can a gas generator charge an electric car?

Now, if a gas generator provides the energy to charge the batteries of an electric car, then the car runs on gasoline - not an ideal solution, but better than an internal combustion engine (because electric motors are more efficient than ICE-machines), and the range is limited only by the size of the gas tank; )

What is the purpose of an alternator in a gas powered car?

The purpose of an alternator in a gas-powered car is to capture energy from the running engine, turn it into 12v DC electricity and use it to charge the car’s 12v battery , which powers the spark plugs, lights, computers and other accessories.

How many volts does an alternator have?

Alternators are usually 12 or 24V. The main EV motor is usually hundreds of volts.

How does a battery work when the alternator is not running?

The battery feeds power through a diode which acts as a one-way street when the alternator is not generating power. This prevents the battery from being overcharged when the alternator is running but allows the battery to power the car when the alternator is not operating.

How does an alternator work?

An alternator (or a generator) in a car takes the rotation motion of the engine (using a belt and pulleys) to create electricity to charge the battery which then supplies all the electricity for the car’s needs. A hybrid car has an alternator (or generator) to take energy from the engine to charge the batteries and a means to take breaking energy ...

What is the DC converter in an electric car?

Instead of an alternator, electric cars have something called a DC-DC converter, which converts the high-voltage power from the battery (usually around 400 volts) down to 12 volts to power the lights, computers, etc. It serves essentially the same purpose, but it’s not an alternator. Jim Murphy.

What voltage does a DC to DC converter use?

What they have instead is a DC to DC converter. The converter lowers the high voltage (300–800 VDC) output of the main battery to ~ 13.6 volts to run the car’s accessories and charge the 12 volt battery.

How does a hybrid car work?

A hybrid car has an alternator (or generator) to take energy from the engine to charge the batteries and a means to take breaking energy to charge the batteries. An electric can has no need for this. It charges its batteries from a cable connected to the electrical grid at a charging station. 32 views.

Why can't an alternator charge an electric car?

An alternator cannot charge an electric car because the power source in such a vehicle is already generated from electricity. As such, it would not make any sense to first convert it one way, only to then revert to electricity. This would result in a net loss in terms of energy, which defeats the purpose.

Why is an alternator used in cars?

Its reason for being in a car is to use the electricity that is generated while it is running to charge the battery. Every vehicle that has a combustible engine will have an alternator. This component is usually located near the engine. You will recognize it because it has a belt running around it.

What causes an alternator to spin?

It all starts with the engine. Again, this is something that an electric vehicle does not have. Most vehicles produced today will have an alternator that becomes activated when the crankshaft from the engine is put into action as you start the car. The belt will start to move. This causes the rotor attached to the alternator to spin rapidly.

Why do we need an alternator?

The reason that an alternator exists is to keep the battery charged in a vehicle. We are talking about a 12-volt battery. As we have discussed, that purpose works well in a traditional vehicle, but not in one that runs on all electricity. In such a car, the 12-volt battery is separately charged via a DC-DC converter.

How does a rotor create electricity?

Some magnets are strategically placed around the rotor. These create a magnetic field as they pass directly over some of the copper wiring that is there in the stator.

What happens when a hybrid car is pressed?

An example of this is what happens at a stoplight. The combustible engine shuts down. When the accelerator is pressed, electricity drives the car for a short distance before the engine turns back on.

Can a hybrid car use an alternator?

Even a plug-in hybrid vehicle can make use of an alternator is certain situations. It contains a larger battery back that will allow the vehicle to travel between 20 and 80 miles purely on electricity before having to switch back to gasoline. This battery pack can be charged two different ways:

What is the difference between an alternator and a motor?

The main difference between an alternator and motor/generators is that some M/Gs will just reduce or increase the voltage from the battery. An alternator is found in gas-powered cars. It has a belt system that spins the rotor that contains an electromagnet. The alternator will produce AC current that is converted to DC power by its rectifiers, ...

What happens when you add an alternator?

If you were to add in an alternator, you will be using up more of the battery power indirectly. The battery power is being used to speed up the vehicle which creates kinetic energy. This kinetic energy will be used up by the alternator through the spinning mechanism that is within an alternator.

What is a M/G and how does it act like an Alternator in a Hybrid?

The battery pack has stored electricity although the voltage is too high to be directly used for items such as lights , the radio , and even to charge the auxiliary battery.

What voltage is used in hybrid generators?

Most of the electronic accessories in a hybrid also require this same voltage. In an alternator, the electricity generated is AC and it is converted in 12 volt DC power to be used to charge the auxiliary battery and to power the onboard devices such as the ignition, radio, and lights. Some of the motor generators resemble an alternator.

Why is a motor generator needed?

It is needed to send the right voltage to the light load sources. The motor/generators will convert the voltage down to a level low enough to charge the auxiliary battery and to power the electrical devices such as the radio, lights, electric doors which are considered as being light load sources.

Do hybrids have a spinning alternator?

All hybrids must have these converters that can give a smooth and consistent voltage flow that will charge the auxiliary battery and power the accessories. Also, the spinning feature of the alternator does not exist in the M/Gs of a hybrid. Nothing is spinning, they are only performing a voltage conversion.

Do hybrid cars have alternators?

Do hybrid cars have alternators? A hybrid does not have an alternator. Its electric motor/generators, called M/Gs, can produce the voltage required. Each of these devices is linked together in a hybrid system through the use of a planetary gearset.
