The question is do you need really need a 500 mile range if you can charge in 5 mins. I say not really. So in theory if 2 cars can charge in 30mins at 400v or at 800v 4 cars using 2 chargers. Then with 2 mega chargers 6 cars can charge in the same period of time. That is progress in the right direction and I’d rather see that, than bigger and heavier batteries. Although batteries also are getting lighter but still the same applies. At some point its just not practical for most and then their is the cost. With 6 cars charging in the same time the company has the potential of making more revenue in the same amount of time. So is a win win. Smaller batteries are lighter and more efficient than most ev’s with a bigger batteries, that are less efficient compared to smaller battery because of the added weight If you don’t require the range all the time, like most people don’t smaller batteries with faster charging times is better for all, and better for resources to.
If you want better for resources then I’ve always said we’re using the wrong figure to sell cars. Range is impressive but we don’t buy ICE based on the range, we don’t sell ICE on range, we do ask about MPG so why aren’t miles per kWh used as key statistics? MpkWh will tell you how far you get per £1 spent, they focus the mind on efficiency, which means the practice of chucking in more storage goes entirely against efficiency. Bigger batteries, more powerful motors so we don’t notice the impact that’s having. Sound familiar? Look through any company’s sales lists and you’ll see that as the kWh rises so does the kW used. You add 20kWh to the battery but that doesn’t automatically add range proportionally, you also add 30/40kW to the motor so that you don’t get complaints about the bigger range feeling comparatively sluggish. However, now the smaller battery does better per £1 than having the ability to drive 400 miles.
