New Batteries Take 2 Minutes to Recharge 70%
I am a bit skeptical.
To recharge a 60kWh Tesla, 70% in 2 min, assuming we hold the charging voltage to 600 Volts means a charging current of 2100 Amps. 600 is the defined "low voltage" threshold.
This would be 1.26 MW of power! Serious switching equipment would be needed.
To carry this would require a cable made from ten 4/0 copper cables, each 0.46 inches (11.7 mm) in diameter.
If we use can use 6000V (medium voltage), then it would require only one 4/0 cable. However the rules are very different above 600V
Any thoughts?
