P = i*V
Numbers for "i" and "V"? Article didn't say ...
i = current in amperes
V = voltage
P = i times V (watts)
Power (in watts, typically) equals current (I) times voltage (V).
The current standards for HVDC fast chargers is 800V with certifications already done for 1000 and 1200V. Most gen 1/2 EVs are 400-480V so chargers are backwards compatible. The CANBUS protocol is used over the signal pins to negotiate the charging amps,volts and voltage ramp rates. No current is ever present until a full handshake is completed in the signal and then the guard pins also signal true earth to ground neutral.
For 370 kw at 800V is 462 amps that’s half of what the NACS plug is rated for uncooled Tesla has tested the NACS plug to.1000 amps uncooled and are looking to get the cert for that to have 1000/1000 V4 supercharger aka the Megacharger a megawatt per plug.
