Question

Who has an idea on the mechanism of charging electric cars?

Answer 1

It depends on the application. As others here have said, you match the charger to the battery voltage. There are some applications that either work on DC (most common) or AC current(more costly in parts, but economical in use).

The AC (Alternating Current) system requires a converter to take battery power which is DC (Direct Current) and converts it to AC when it powers the AC motor. An oscillator is needed to cycle power to give it varying speeds, other wise a transmission will be needed. This is why a dc system is more common, because it is simpler to operate, but not as economical.

My idea would be to have a big horizontal flywheel under the car spinning like a segway, with the motor connected to a variable shaft. The adjustment would be driven by the accelerator pedal. The shaft would ride more to the outer edge as more speed is needed. When the vehicle is stopped in traffic, the flywheel spins the motor to generate power back to the battery and not to move the vehicle.

Answer 2

A transformer reduces voltage to just over what the battery would need. A rectifier  converts it to DC. A voltage regulator limits voltage.

There are electronic smart chargers that get a bit more charging speed and even economy.

But do we have enough grid power to power our fleet of cars? not even close.

Answer 3

You should be asking what creates the electricity for electric cars.

Answer 4

You plug the car in. Electricity goes to a battery. Battery sends electricity to motor. Motor turns wheels. Tada! Then five minutes later, it needs to charge again.

Answer 5

s***w your garden hose to the batteries.  Hydroelectric power is very green.
