Re: Overview of Early Electric Cars
#2The problem is the same as its always been: the batteries still aren't quite good enough. Batteries still need to become cheaper, safer, more energy dense, more durable, and faster charging.
But the good news is that batteries are improving year by year. Probably by 2025 there will be large scale production of EVs with solid-state batteries with better energy density, safety, and charging speeds.
It'll also be good to see cars start to make use of ultra-capacitor buffers to more efficiently recuperate braking energy. The more you can protect the main battery with a capacitor buffer, the longer it'll last.

I think they are. Most new electric cars are like at least 250 mile range, and Tesla's flagship Model S starts out at over 400 mile range (and their 520 mile range version will be available in about 12 months... that's more than most conventionally fueled cars). Charge speed is fine (you'll spend less time overall than you spend at gas stations) and safety is overall superior. Battery life is also not a concern as the battery in these vehicles will outlast the car.
I just don't think people realize that batteries actually are plenty good enough now. No breakthrough is needed. It's about driving down the cost to as low as possible and scaling out charging standards and networks. And ultimately, just banning new conventional cars outright (starting out by requiring all new vehicles to have a plug in a few years).

Curious how you are calculating this. I usually spend about 60-120 seconds refilling my tank once every 300 miles. (15 gallon tank, about 30 mpg).
Because gas stations are everywhere, I never have to plan a specific route based on availability of gas stations, or use an app to find where the stations are, or even think about how much gas I have, as I know there is a station on the way to wherever I am going, and all I need to do is pull over. I even have the luxury of refusing to stop at gas stations on the left side of the road because there will be another station a block down on the right side.
But with electric you have to go out of your way to find a charging station and it takes longer than 100 seconds to fully charge your car. So how can it be less time overall?

No, you need to think about what it means when all cars are electric. Current charging speeds lead to long queues at chargers like this:

No car on the road at the moment is capable of making full use of 350 kW CCS chargers (the Porsche Taycan comes closest at 270 kW). Ideally you'd want a flat charging curve at 350 kW to allow for more cars to be served by each charger.
If you had a flat charging curve at 350 kW it would take about 13 minutes to go from 0 to 80% state of charge on a 100 kWh battery. Still slower than fueling an ICE car and still not full battery capacity, but you should be able handle 4 cars per hour per charger.

If you can charge at home overnight (or at work during the day) then you won't need to go anywhere else.

With electric you plug the car in overnight while it is parked. It is full every morning, and you never need to go out of your way to charge it unless you are on an intercity trip.
It really is more convenient than gasoline!

It's still abysmally slow.

I don't think most people would consider only charging at home an advantage or "convenience". If you even need to go to a charging station once and spend a half hour to an hour there, that becomes very inconvenient, even if you only need to do that once a month.
Most people would like to have a charging station always nearby so that it becomes stateless for them, so that they don't need to think about how much they drove that day, and they want the charging to happen within a minute or so to view it as equally convenient as gas.
PEV have many advantages, but let's be realistic -- the convenience of charging is a disadvantage.
