Why does 110 charge the car at 3mph, but 220 charge at 35mph? It’s 2x volts but >10x charge speed.
In: Physics
Speaking for the US electrical system.
The differences is in the Amperage through the circuit breaker, and how many wires are carrying power. 110VAC power is on a single power wire, and limited to 20 amps by the circuit breaker. 220VAC (three phase) power is carried on three wires, and limited by a 50 amp circuit breaker.
The 110 VAC has a potential of approx 2,200 watts of potential power, The 220VAC has approximately, 19,000 watts of potential power. The 220VAC three phase can delivery approximately 860% more power than the 110VAC
From what i have seen, in certain parts of Europe, the 220 is brought in on a single wire ,and limited by a 50 amp breaker, it has approximately 11,000 watts of potential power. The 220VAC single phase can delivery approximately 500% more power than the 110VAC
