Why Dont Teslas Have Alternators That Can Recharge The Car

We dont because it doesnt work that way. The tesla doesnt have a combustion engine.

How Much Power Must Be Given From The Battery To Start The Alternator Quora

Why dont teslas have alternators that can recharge the car. The way to test if your alternator is damaged is by using a multimeter. On EV Self-Charging Whats out there. No different than alternator on gas car powered by motor asking 1600 kw that dont stall the car out does it still runs out of gas the same way externally powered electric batteries run out too.

Most of the higher end generators do this now with an alternator powering an inverter. Every time you let off on the go pedal they kick in and recharge the battery. Why cant electric cars charge themselves.

The traction pack is only engaged while a Tesla is in Drive mode or during a recharge session. The alternator on a car takes away horsepowerThe car only has one 12v batteryand recives 14amps from the alt. You would need an alt that threw over.

You STILL dont get more power out than you put in. Its battery runs the car so it cant also charge itself. Although an alternator can recharge the battery in your car it wont keep it going forever.

I dont see why Tesla cant put an alternator on each wheel to recharge the battery as you drive. Why Teslas dontand canthave solar roofs. But the other problem with this idea is that the alternator isnt free it loads the engine the more you draw from it meaning you need more gas to keep it turning the power comes from the fuel in the tank its not free.

It sure does but its not a huge amount a typical 55A 12v alternator can generate 660w an electric car needs about 10000w just to cruise at 30mph. Charging the tesla at anything greater than 252 volts will result in disaster for you and your vehicle. A Tesla rival the Karma Revero.

While operating your Tesla vehicle a 400V to 12V DC-DC converter provides 12V power from the main battery pack to run all the vehicles electronics similar to an alternator on the ICE vehicle. An alternator would only slow the car down a little tiny bit and certainly the recharging would more than make up for it. The difference between this and regenerative breaks would be the low resistance in the alternator.

Its pretty well documented in this forum that Teslas are finicky and have trouble charging on direct AC generators. They have DC to DC converters. The alternator cant run the car if it could it would require much more energy than the internal combusion engine could provide.

This works very differently from an electric vehicle remember an electric vehicle does not have an alternator that will charge the battery of an electric vehicle because it does not use an internal combustion engine rather an induction motor and a set of rechargeable batteries although some might argue that what if an alternator was fit inside of the electric vehicle to recharge the batteries. This converts high voltage DC from the battery pack to low voltage 1314V DC to charge the 12V battery. You are correct in self powering wont work net loss in internal system but externally powered systems can capture inefficiencies along the way.

But the fine print makes this a terrible deal even if. You should carefully tap the alternator with a hammer when the car is running in order to test the levels and determine if the alternator is at fault. Basically youre asking why you cant charge a battery with the same battery.

This is why it is important for you to distinguish if you have a bad alternator or a weakdead battery. The reason that the DC-AC conversion is desirable is to provide a stable line frequency for the Tesla chargers. Why Other Car Companies Dont Use Tesla Superchargers Tesla says it will give its charging technology to any automaker who wants it.

As the tire spins when the car is moving the alternator creates electricity to charge the batteries. The power output needs to be greater than the additional power needed to. They can take everything your alternator can provide.

You then buy a non-Tesla EV like a Volkswagen ID4You dont want to. If you only mean to have the drive motor to spin an alternator to charge a 12V battery to change some high voltage main battery power to lower voltage accessory battery power that can work. In this article we will seek to answer the burning question in many peoples minds.

It turns out that he had meant a solar roof that unfolds from the trunk and overs the current car hood. Now what your alternator can provide without catching on fire is another story. Teslas already have an alternator or in many cases two of them.

Suppose you already have a Tesla and previously installed a Tesla Wall Connector in your garage. Which is why if your battery seems to be weak or had died its highly likey that your alternator has gone bad as well. Like i said mine are charging at bulk at 60 amps.

No Tesla and other electric cars dont have alternators. These are relatively efficient and dont have any moving parts. The most common reason that your alternator is not charging is because of a damaged alternator.

The fact is that at this current moment in time we dont have either the technology or infrastructure to ensure cars can either self-charge or passively charge.
