Not smaller than 3 AWG copper, or not smaller than 1 AWG aluminum. If this is a longer run (say to an out-building) than you need to consider line losses and go with a larger wire size.

There is more to the question than meets the eye. Is this a 100A residential service that you are feeding with the wire in question? Is it a breaker for a sub-panel at a single family residence?
If a Dwelling Service, according to NEC Table 310.15(B)(7), 4AWG copper or 2AWG aluminum is sufficient.
If a sub-panel for a dwelling, you may be able to get by with the same, if the authority having jurisdiction (inspector) interprets this Table in that way.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
you will need 21.81 amps at 220v
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps
6240 watts if it's on a 240 volt circuit. A better answer is to just learn that amps X volts = watts.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
you will need 21.81 amps at 220v
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.

Not sure about how many Watts your 36 volt charger uses, but you can find out by this formula... Volts X Amps = Watts.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
On a 120 volt supply, up to 360 watts. On a 240 volt supply, up to 720 watts.
10000 watts / 220 volts = 45.4545 amperes
Current (amps) = power (watts) / voltage = 100/240 = 0.42 amps
