That maybe so but what’s the average time it takes to put enough fuel in a ICE car to enable 500 miles of travel compared to charging a battery in an EV to do the same mileage?
That isn't the point.
The majority of vehicles spend the majority of their time parked up. That is where charging should occur so how long it takes is irrelevant. The car will be parked there anyway - an extra few seconds to shove a cable into the car is the only additional effort.
Today that is mostly people who can park on their own property and charge overnight.
In the future that will be for any EV parked anywhere. What's missing today is the charging facilities at all of these other places - but these are being installed. It will take a long time, but then so will replacing existing ICE vehicles with electric.
That is why if you don't have easy access to charging where your vehicle is parked most of the time, buying an EV today is not a sensible thing to do.
There will always be a requirement for public charging but even there, most of that should be slow AC charging. If someone drives to a place for a reason and the car is parked for an hour or four, that is when charging should occur.
For longer journeys rapid charging is required and already exists, for those short stops at motorway services and similar which people should be making anyway.
The mindset of driving around until your car has no fuel left and then going to some special filling up place to cram a weeks worth of fuel in is going away. EVs are not like that, and anyone who tries to use them like that will have problems.
Also, is the range on an ICE vehicle severely affected by use of lights, heater, a/c etc?
Everything has an effect, but it's insignificant.
Worst case would be a resistive heater, but even at a hefty 3000W on continuously (which would cook those in the car after a while), and it was on for a full two hours at that high output, that's 6kWh or about 20 miles of range for a typical car.
While 20 miles of range is noticeable, over a 2 hour driving journey it's mostly irrelevant. Perhaps 10% of the range of a vehicle that can do 200 miles.
In reality even lower spec cars with resistive heaters do not use 3000W all the time, and better vehicles use the AC compressor for heating which will cut power consumption for heating by at least half and usually more.
Other items such as lights, radio and all the other electrical crap in vehicles is so low in power use that any range loss isn't even noticeable.
EV batteries are massive, usually 50kWh to 80kWh. An average UK home uses about 10kWh of electricity per day, a single charge of a typical EV could power that house for a week.
Most of the range lost in cold weather is due to the battery itself not working well at low temperatures, which is why most modern EVs have battery heating to avoid this problem.
