Can a motor charge a battery?
Charging a BatteryEdit
The motor must be able to produce enough voltage to charge the battery. For example if the rated voltage of the battery is 5 V then the motor must be able to produce at least 5 V. It also must be able to generate enough current so that the time required to charge the battery is lowered.
How does car battery charge itself?
The battery is charged by an alternator on modern cars, or by a dynamo on earlier ones. Both are types of generator , and are driven by a belt from the engine . The alternator consists of a stator – a stationary set of wire coil windings, inside which a rotor revolves.
How do I charge my engine battery?
Hooking up the Battery Charger
- Make sure the charger is off.
- Hook-up the positive cable on the charger to the positive terminal on the battery.
- Hook up the negative cable on the charger to the negative terminal on the battery.
- Set the charger to the slowest charge rate.
- Turn on the charger and set the timer.
Can you use an alternator as a motor?
The humble automotive alternator hides an interesting secret. Known as the part that converts power from internal combustion into the electricity needed to run everything else, they can also themselves be used as an electric motor.
Can an electric motor power itself?
YES, but it can only be done long term with an electric motor that is designed to also run as a generator and if the generator will be paralleled with other generation the motor will need to be a synchronous motor.
Can a completely dead battery be recharged?
If a battery is completely dead but has been revived by a jump start, there are ways to fully recharge your battery. The first is, as mentioned, by driving around. If that does not seem to work, however, car battery chargers can regenerate all of the charge into a battery.
Can a battery be too dead to charge?
YES, a car battery can get so dead it will not receive a jump start anymore. To cut to the chase, and just before we get to the meaty stuff, a “dead” car battery is an indicator of different factors—and almost always, these occur all at the same time.
How long does it take to charge a completely dead car battery?
Recharging a dead car battery can take at least 4 hours, and even up to 24 hours depending on the power of the charger and the size of the battery. Usually, battery chargers put out around four amps, but there are more powerful chargers out there.
How long should I drive my car after a jump start?
about 30 minutes
Does a car battery charge itself while driving?
You won’t fully recharge your battery by going for a drive, idling the engine, or going for a short stop-start trip. In fact, ‘surface’ charging or continuous undercharging will lower the capacity of the battery over time and shorten its life.
Does revving the engine charge the battery?
Yes, it was true then, and it’s true now. The battery will charge faster if you rev the engine faster. And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery. …
What can drain a car battery when the car is off?
Something is causing a “parasitic draw.”
What may drain a car battery when it’s off, however, are things such as interior lights, door lights, or even bad fuses. … But when the engine is off, the alternator can’t recharge the battery, allowing little electrical mishaps to drain your battery entirely.
How long does it take to charge a car battery with a 12 volt charger?
How do you fix a battery that doesn’t hold a charge?
How to Fix a Car Battery That Won’t Hold a Charge
