Silex Power Claims Electric Vehicle With 621-Mile Range & 10-Minute Charge Time

February 25th, 2013 by  

Silex Power has said that it has designed an electric vehicle — the Chreos — that achieves outstanding range, performance, and charge time.

Instead of simply listing these claims, let us spend more time exploring the possibility of them, and which technologies on the market can achieve them, or at least come close to achieving them, because they could be using new battery technology, and prototype battery technology is well ahead of what is on the market.

Silex Power claimed that the battery bank can charge in 10 minutes. This is highly unusual. However, battery technology that can charge in 15 minutes is already on the market (Toshiba SuperCharge lithium titanate batteries). Prototype batteries developed at MIT have charged in 20 seconds, and there is another more recent one that charges in ten minutes.

As for the claim that it can travel 621 miles (1,000 km) per charge, I have never seen an electric vehicle do that. However, prototype battery technology has the ability to store ten times as much energy as typical lithium-ion batteries.

The performance claim that it can accelerate from 0 to 60 mph in 2.9 seconds is also highly unusual. However, the “White Zombie” is only 0.1 seconds slower, at 3 seconds.

The Chreos (allegedly) achieves these outstanding feats using a 640 brake horsepower propulsion system that produces 4400 Newton-metres (3,245 pound-feet) of torque.

    Those citing that batteries cannot handle the charge or life cycle, please check out graphene. This is completely doable and is cheap. but similarly to LED’s the prices will rocket once people catch on. Hence a 20bil Euro grant to further the studies in graphene and get ahead of the market by the EU.

    • graphene has some very attractive qualities, but as yet, it’s unclear if it will ever make it out of the lab in such applications.

    I sure hope I’m wrong, and would love to see otherwise, but it’s vaporware.

    The car hasn’t even been made – or at least there isn’t a picture of it in that video! That video is simply digital renderings of a concept body. I’ve seen enough of them to recognize the signs of it. (It’s not even high budget rendering – a decently skilled person could do this as a side project on a high end home computer)

    This is vaporware and bad vaporware at that. If you can charge the thing in under 10 minutes why would you put enough batteries in it for over 600 miles which will add ~$50,000 to the cost. Save yourself a whole lot of weight and cost and just charge it a little more often. I don’t understand why when you can just make up any numbers you want to without the need to actually establish you can achieve any of them as they have here why you would make up numbers that anyone with the slightest clue about EV’s would simply laugh at.

    • high speed charging consumes the cycle life of batteries. It best for the battery life that charge level is maintained with slow charging at 30-60 % of capacity. This optimizes the battery life. Full charge and full discharge and supercharging should only be used when it is necessary.

    Vaporware. Great article though.

    Many static photos. Lets see this thing in action. Price??

  • bs…

      liquid nitrogen cooling in the charging cable, which could be built using less resistant materials bro. would it still be dangerous then? we will have to see

  • jolandic

    Hugh! Nice!
    I hope that they don’t go bankrupt, and I wish the same for Tesla motors! They made a 400 million $ loss last year
