Beyond Tesla's Superchargers Are .... Silex Hyperchargers ???

Silex Power's HyperCharging technology

Silex Power's HyperCharging technology

The word "hyper", when used as a prefix, is generally considered to be bigger and better than anything prefixed with "super".

Hypermarkets and superstores, for example. Or hypercars like the thousand-horsepower Bugatti Veyron, compared to supercars like the 560-horsepower Ferrari 458.

Thus, Silex Power's 'HyperCharging' technology could be thought of as a stage above Tesla Motors' Superchagers. Like a Supercharger, but... hyper-er.

How hyper? The ability to charge a 200 kWh battery pack in "less than 10 minutes" will give you some clue. Tesla's Superchargers take twice as long to deliver a 50 percent charge to an 85 kWh Model S, for comparison.

Silex Power describes them as fast DC-to-DC chargers capable of delivering up to 1.5 megawatts of power to a battery pack, the stations connected directly to medium tension power lines. As you can probably guess, they're intended for highway charging stations rather than your garage.

The catch? It's all purely hypothetical right now.

To its credit, Silex Power--previously responsible for the equally-virtual Chreos luxury electric sedan--hasn't claimed to have invented such a system yet.

Instead, it's described as a "unique and highly ambitious project", but one they see becoming a mainstream solution in a few years.

The HyperCharging system will use a proprietary plug design (currently on the drawing board, natch) to deliver 1,000-amp currents and voltages between 360V and 1,440V, depending on the vehicle being charged.

Other, standard plugs would be offered on its Chreos vehicle, to ensure compatibility with lesser chargers (our words, not theirs...).

The company also says its design removes the need for an inverter on the vehicle, saving space, cost and weight. And like many current electric vehicles and charging stations, HyperChargers will have a wireless connection for information exchange.

But as with the Chreos, we're finding it hard to get excited just yet.

Once again, there's nothing here that isn't theoretically possible, but until Silex Power emerges with some physical examples of its wonderful-sounding technology, it's hard to believe the hype.

We'll stick with Superchargers for the time being, thanks...

  1. It would make more sense to have hypercapacitor banks accumulate charge based on demand and then be able to discharge at 1.5MW.. This would enable sites to not have to pay to maintain much higher power connections that may be barely utilized.

  2. Vaporware.

  3. Let me guess: they're looking for investors.

  4. I was getting all excited and started doing some math, then I read this: "The catch? It's all purely hypothetical right now."

    Okay. So, I claim that I can make a 15MW charger and it will charge the car in 1 min. But that is hypothetical right now...

    Then I read this: "The company also says its design removes the need for an inverter on the vehicle, saving space, cost and weight. "

    Then this car can't be charged on the regular AC network available everywhere. So, it just becomes another expensive toy that will never happen...

  5. Why would I use their charging system when I can just drop some beer cans into my Mr Fusion? Both technologies are about equally real, but I'm giving the edge to Mr Fusion.

  6. Sorry Norm, wrong thumb, I meant an "UP"! I think Mr Fusion is great!

    @John V, please correct it!

  7. Funny Norm, but well, yes and no. Yes Mr. Fusion is as close to reality as Silex Power's yet to be prototyped DC chargerware. Although, if you look at ship to shore power plugs, this level of power delivery is currently available and in use. Just don't expect to be able to pull up and plug in your Chreos or even Tesla sedan anytime soon.

  8. It takes 85kw to move the "S" 250 miles. Why? Because the car is weighted down with a low energy density battery pack. I think Tesla has a good solution to charging the car and the range problem for now. However, with lighter cells and thus a lighter car, you wouldn't need 85kws, perhaps a 50kw or less pack would do, so you can then place a limit on how large the quick charger will be.

    The key to mass adoption for EVs is the battery. It must be a higher energy density, weigh a lot less and cost a quarter of today's prices. It's the battery stupid!, Always!

  9. Sorry, taking even hundreds of lbs of battery away from a 4500 lb car is not going to be sufficient for a 35 kWh reduction in storage. And more likely to reach longer ranges with less charging, some models would preferably have even more kWh's.

  10. Another thing to point out that weight is NOT the only limiting factor for range.

    Speed, climate control and performance are all factors. Improving battery will help, but it is NOT going to produce the kind of reduction like you claims. 35KWh reduction on a 85KWh battery is an improvement of 41%. That is a 178mpge efficiency for the same 265 miles range.

    Almost impossible for even a 2,000 lbs car, much less on a 4,000lb+ car...

  11. Hyper-electrical chargers would make sense if coupled to nuclear, hydro, or even wind power-plants i.e.the MW-hr electrical energy producers. Then electricity could be sent to remote distances as AC and then using transformers and bench of capacitors as converters at the local power stations. But the average costs of those power-plants are in the billion dollar range (the cost of infrastructure to deliver, transform, and convert that energy before it can be used is not included). When you divide cost by energy produced the resulting number is in the order of $10,000/kwh. This is, you would need to pay $85,000 to fully charge your Tesla in minutes just go 250 miles! Not even the Bill Gates, Warren Buffets, and Carlos Selim...cont.

  12. (the hyper money makers of our world) as those guys are usually cautious with their expending. MW/h producers of our world make sense when projected to power cities or big industrial complexes where money return is guaranteed. So, sadly, it would a pretty ideal world the one where the powers that be would build a nuclear power plant just to power a few vehicles in a city...IMO, the future of EV vehicles continues to have its best shot in the solar energy production, and in the use of nano technologies to produce batteries

  13. Musk is hosting a live demo of a "faster than gas fill-up" charger on June 20. Other than the announcement, no further details were given. A full charge? 85kwh? 5 minute stop to gain another 200 miles?

    I am very excited; BUT Elon's unfortunate word game when he announced the $500 Model S lease makes me nervous.

  14. a lot of heat, at 1.5 MW,

  15. yes the cable would have to be as big as my leg or liquid cooled. This would also include the cable(s) inside the car.
