Comment on EV Batteries Are Dangerous to Repair. Here’s Why Mechanics Are Doing So Anyway

I’ve been surprised by USB-C. I recently bought a Xiaomi phone and it takes like 10 minutes to charge with the charger that comes with the phone (and it still works with the other ones). It’s 120 watts

At that rate it’d still take 12 hours to charge a 1440 watt hour battery, which isn’t the hour or two that people are used to with superchargers these days, but actually surprisingly servicable.

That’s 50x smaller than an EV battery. Being able to drive once every two months doesn’t seem practical.

Where did you pull that 1440Wh number from? The battery in my plug-in hybrid is 20kWh, and that’s still small compared to a full EV.

  Ah shit, I googled the number but it looks like I got the number for a battery in an internal combustion engine car, apologies. I’m an electronics person, not a car person

    Understandable. Just for the sake of comparison to a smartphone 120W fast charger, level 1 EV chargers (which can still take days to fully charge a completely drained EV) will generally deliver between 1000 and 1500W. Level 2 (the fastest you’ll typically see installed in people’s homes) range from about 7kW to 19kW. Level 3 fast chargers typically operate from about 60 to 250kW and unlike level 1 and 2 which deliver AC to the car to be handled by the vehicles internal rectifier/charger, level 3 delivers DC.

1.44kWh Is roughly 7-10km of driving, depending on the car and weather.
