Current Cost of 50-kW CHAdeMO DC Quick Charger Around $16,500?

MAY 29 2013 BY MARK KANE 11

Earlier this month, Nissan and Car Charging Group announced a partnership to install 48 DC quick chargers in US before the end of 2013.  But the most interesting bit of information that we found was in Car Charging Group’s 10-K SEC filling.

Car Charging Group stated that all 48 devices were already purchased from Aerovironment in March. Moreover, the total price was $792,912, which works out to $16,644 per CHAdeMO DC quick charger—almost surely that is for a 50-kW unit (without installation costs).

“On March 28, 2013, we purchased 48 fast chargers from Aerovironment at an aggregate cost of $792,912.  The Company entered into joint marketing agreement with Nissan North America for which among other matters requires us to build, own, operate and maintain a network of 48 fast chargers throughout the United States and create an auto dealer network promotion and referral program so as to facilitate sales of electric vehicles to their potential customers. Revenue received from the agreement on March 29, 2013, $782,880 is deferred and recognized ratably over the three year life of the chargers upon installation.  We are required to install the network by December 31, 2013.”

What else is news?  Well, it seems that Nissan will pay some $782,880 to Car Charging Group over three years of successful operation of the quick-charge units.

48 quick chargers is the biggest order to date for AeroVironment. Notable here is that Car Charging Group has never before invested in DC quick chargers.  Maybe this marks a turning points of sorts with others moving mostly from AC to DC network, too.  It’s also likely to be easier to make money be operating DC quick-chargers, as compared to lower powered AC units.

It is also interesting that they are sourcing AV units (with Nissan paying money towards them) when Nissan sells CHAdeMOs for $10k.

50kW seems low for a fast charger and limiting commercially in light of the SAE standard that most fast chargers will also offer (just provide two plugs at the “pump”) Ultimately, the SAE standard will provide up to 100kw for DC level 2 charging and these chargers need to be capable of that charge rate or risk being left like the old inductive paddle chargers.

Oh and Tesla. A comment thread must mention Tesla. Ahh, I feel better.

The current crop of EVs (aside from Teslas) can only charge at 50 kW for a small period of time – the charge rate tapers significantly once around 50% full.

Imagine these chargers are the new Nissan designed chargers they are currently installing in their dealerships, not the big bulky AV unit pictured here.

True, but some of us like to look past today’s “first generation” EVs, and into the future. QC stations should be set up to allow for a lot of growth. I personally think that 100kW is a good spot. That’s over 300 miles/hour for any modern EV. As batteries get larger, the amount of time at full rate will grow. 50kW, by contrast, seems a little limiting when looking 10 years into the future.

There’s plenty of time in the future to install higher capacity charging stations. Building a 100 kW charging station costs a lot more than a 50 kW charging station – not to mention the utility costs.

Even today there are people choosing to install 25 kW CHAdeMO stations instead of 50 kW CHAdeMO stations simply to reduce the installation and operating costs.

Charging time goes up a small amount (maybe 15-20%) but the lower installation and operating costs let them install more stations today.

From the label in the back of an eVgo CHAdeMO charger:

EV Quick Charger
Model No. NSQC442E
Input 480V 3ϕ 60Hz 50KVA 60A
Output 50-500V DC 44kW max 120A
-10°C~40°C Rainproof
UL Listed

Where did you find this station?

They don’t need to cost anywhere near that nor be anywhere near that size. So much stupidity governs the recharge products of EVs. J1772 is a glorified extension cord yet they sold for 3000$ and even today they cost a minimum of 600$

125A DC is just not that hard to do.

Does this include installation? 480V electrical line installation isn’t cheap.

44kW? 50kW? I like this. I ascertain that with current battery chemistries, we are limited to 30 minute/80% quick charging. This means that if your battery is very much smaller in kiloWatt-hours than the charger it’s plugged into has power in kiloWatts, you can’t use all the available power to fullest effect.

A 25kW station works perfect for a 24kWh LEAF, and a 90kW supercharger works perfect for a 85kWh Model S. It’s nice to know we have a doubling of capacity between current models (LEAF 24kWh) and max charging standard station spec (50kW) and that people are actually building to that spec. Nice to know someone (other than Tesla) at least imagines in the future one day making a 40+kWh car.

i like the 44 kw always ’rounded up’ to 50 kw. Most of these things I’ve spec’d out have a boosting transformer for 208 volt exisiting facilities. Even if they don’t, autotransformers doing the same aren’t much coin.
