Tesla’s documentation says that the Model 3 is able to charge at up to 44 miles per hour when using a Wall Connector on a 240 volt 60 amp circuit. I’ve witnessed on several occasions that my Model 3 is actually able to get up to a charge rate of 45 miles per hour. Anyone else seeing this?

Mine gets 46 miles per hour at 48 amps on occasion, usually 45 though

Your voltage is probably just above 240V.

I have noticed the voltage spiking to 242 volts on occasion during charging but I’ve seen my Model 3 report the 45 mi/hr charge rate when the voltage is down a bit to 237 volts.

I've found the mi/hr rating when charging to be pretty useless. You should really only care about the kW the car is charging at.
This. The mi/hr rating calculation appears to be reverse-engineered from the overall range calculation. So on a brand new battery, if you're getting a slightly higher maximum charge rate, my psychic powers tell me your 100% charge range is > 310mi (this is the case with mine- it reads 315mi at 100%). The true values for any given charge are battery SoC and kW draw, anything else is derived from "fluffy" values.
