That's...Not really that impressive. I use 145Wh/km during the summer (scandinavia) with mixed highway and main road driving, if I had a 150Kwh I could get that range easily. Long range with a humongous battery is pretty expected.
Not really the point of the article. The point is that they've built a 150Kw pack that will fit into a sedan.
Or that they can replicate amazing results under test conditions rather than real world... you know, coming out of China which I don't trust anyway.
650 miles on a 150Kw pack isn't some efficiency record.
No, but making a battery at a mass that allows for that kind of efficiency has to come with asterisks.
But I would assume that of any country's findings that result in a headline like this.
I mean it’s 4.1 kwh/mi, which is very good on a battery that heavy. It’s not massive leap, but that gives me hope that real world mass production.
The battery/car weight has way less impact on range than you'd think when just cruising on highway/main road where you have minimal/no accelerations from stopped. I barely see a difference in range between my car with just me in it and fully loaded with 4 people and luggage for 3 weeks of camping.
