EEStor Permittivity Testing: It’s a Pass!

Good old EEStor released a third-party verification of the permittivity of their insulating material – the verdict? It’s a pass and expectations have been met from -20 degrees celcius to 65C. Sorry, I know I’m here partying all on my own, so let me back track a bit and give a bit of background on this…

EEStor Cell

As most are probably already aware, batteries have always plagued the electric vehicle for a mass of reasons: they don’t offer sufficient range, are too heavy, too costly, too big, don’t discharge fast enough, don’t charge fast enough and performance degrades over time. Yeah, that’s a big list of flaws and so many may be surprised that I’m a big proponent of the development of electric vehicles. One of the reasons is because of a lot of the cool technologies on the horizon such as the EEstor EESU (Electrical Energy Storage Unit). EEStor wants to pack 52KWh of energy in these things in a small package weighing in at around 300 pounds. To give you an idea of how much energy that is, most of you can probably power your houses for a full day and the more energy concious among you for a couple of days.

Now, the reason that this is such a breakthrough is because how much energy a capacitor can store is modeled by the following equation:

energy = ( capacitance x voltage ^ 2 ) / 2

What does this mean to your life? Basically that if we can increase voltage in a capacitor, we get exponential gains in how much energy we are storing. To get those really high voltages, we need to be able to place conductive plates really close together with an excellent insulator in between. The real breakthrough is in this insulating material as the permittivity testing shows that we EEStor has created a material which is hugely better than previous known materials. The independent lab verification is a huge step forward since the company has never been forthcoming about anything they do. In fact, I’d almost say that they hide as much as they can from the public almost to the point that people are thinking EEStor is some kind of scam.

Now there is of course a lot more to this plot. Lockheed Martin actually signed an exclusive deal with them about a year ago, as did a publicly traded Canadian electric car maker called Zenn Motors. When this story broke, stock at Zenn shot way, way up. In fact, let me pull a picture off of Google Finance right now for you guys!

So yeah, all the scientific mumbo jumbo actually means a lot to the future of the electric vehicle. Eventually I’ll get around to posting an article for you guys which showcases some of the most exciting green automotive technologies of the future that may very well lead the way to finally replacing fuel. As always, stay tuned and subscribe to the RSS feed if you want to be updated whenever I post an oh-so-interesting article! And yes, I’ll make a bigger RSS button eventually. Peace out!
