How does realworld EV charging compare to what manufacturers claim?

We see all these charging time claims from manufacturers, but what are the actual EV charging realities you've experienced? I'm talking about everything from home charging speeds to public station availability and reliability. I've done several crosscountry trips in my EV and the charging experience can vary wildly from what's advertised.

The EV charging realities are often different from manufacturer claims. Fast charging speeds are highly dependent on battery temperature and state of charge. The advertised peak charging rate might only be achievable between 10-50% battery, then it slows down. Also, public charging station availability looks better on maps than in reality broken chargers are common, and wait times can be long during peak travel periods.

Home charging installation is more straightforward than public charging. Level 2 at home usually delivers close to advertised speeds. But public fast charging EV charging time realities include time to get the charger working, payment processing, and actual charging curve. I've found adding 50% to manufacturer's claimed charging times gives a more realistic estimate for trip planning.

The reliability of public charging networks varies dramatically. Some networks have excellent uptime, others are frequently broken. Charging speeds also depend on how many other cars are charging simultaneously at a location. And don't forget about EV charging etiquette issues like people leaving their cars parked at chargers after they're done, which adds unexpected waiting time.

Cold weather adds another layer to charging realities. Fast charging speeds can be significantly reduced if the battery is cold. Some EVs have battery preconditioning features that help, but you need to activate them before arriving at the charger. Also, public charging station availability in winter can be worse if chargers are blocked by snow or ice.
