CDZ EV question

[WinterBorn]

Why does the battery in an ICE vehicle keep a charge?

Because energy is expended to charge it.

 

[jc456]

Because energy is expended to charge it.

But how is it charging while the car is in motion? Where’s the energy coming from?

 

[WinterBorn]

But how is it charging while the car is in motion? Where’s the energy coming from?

In an ICE vehicle, the fuel is ignited, which releases energy.

The energy is used to power the vehicle and to charge the battery via an alternator.

If you look at the engine, there is a belt weaving though a number of pulleys. One of those is connected to the alternator. if the engine is on, it spins and charges the battery. The amount of energy needed is taken from the ICE. That is reflected in MPG.

Creates heat right? How does the engine keep cool?

Yep! is there an alternator that connects to those pulleys and belts, right? Why do you suppose that is set up for?

 

[WinterBorn]

Creates heat right? How does the engine keep cool?

The controlled explosion of fuel creates both kinetic energy and heat. The engine is kept cool via a circulating water system or by circulating air over the engine.

How does the water circulate?

 

[WinterBorn]

It is set up to convert the energy from the internal combustion into electrical energy. But, as AsherN said, it comes at a cost. The resistance needed to generate electricity causes a reduction in available energy.

 

[WinterBorn]

How does the water circulate?

Is this going somewhere relevant to the topic?

Most vehicles have a water pump that circulates the water.

The belt and pulleys turn the alternator to charge the battery right?

Yes, that is right.

Sure, the same type belt and pulley system tied off a spinning axle could connect to an alternator using the energy off the axle to charge the battery

 

[AsherN]

The belt and pulleys turn the alternator to charge the battery right?

And the water pump to keep the fluids moving to cool the engine. Are you trolling or do you really don't know what goes on in the engine bay?

 

[WinterBorn]

Sure, the same type belt and pulley system tied off a spinning axle could connect to an alternator using the energy off the axle to charge the battery

And that would provide resistance against the axle, which would lower the amount of energy getting to the wheels.

 

[jc456]

Yes, that is right.

Why can’t a spinning axle perform the same action as the spinning engine?

 

[WinterBorn]

Why can’t a spinning axle perform the same action as the spinning engine?

In order to spin the pulley, and thereby the belt, energy is used that would ordinarily be used to power the wheels.

Every function by the pulley and belts pulls energy off of the system designed to power the wheels.

There is a net loss of energy.

 

[AsherN]

In an EV? sure. BUT the alternator needs energy to spin. That is energy required to move the wheels. Energy cannot be created. The battery supplies 10 Watts. Your choice is to send that 10 Watts to the drive train, or to use 10% to power an alternator. So now your drive train is not using 100% of the energy. The alternator will use some of that 10% because friction, etc. Assume 10%. So for every 10 Watts produced by the battery, 0.9 goes bat to the battery. Yes, it does extend the battery capacity, but eventually, the battery will deplete.

ICE is only somewhat different as it converts the potential energy stored in the fuel, the more energy needed, te more fuel is consumed. But at some point, you need to replenish the fuel source.

 

[jc456]

And the water pump to keep the fluids moving to cool the engine. Are you trolling or do you really don't know what goes on in the engine bay?

Yep, all because of the engine itself. The engine cools itself and charges the battery.

Yep, and in an EV a battery is used to provide energy to move the car and its axles.
