This thing is larger than house

If your EV is really big you need special fast charging, right?

How about Kalmar’s 600 kW fast charging solution for electric powered shuttle and straddle carriers?

Full charge takes just a few minutes, so batteries can be recharged while awaiting a new batch of containers.

If you are interested, next year Kalmar intends to begin sales of these electric vehicles/chargers, though we doubt it qualifies for the tax credit.

“The Kalmar FastCharge solution is based on the same opportunity charging technology that is used in electric buses. The charging station with a pantograph direct current charging system is located flexibly on the working route of the machines in the terminal. The machine has modern Lithium-ion (Li-ion) batteries which enable fast charging to be used. Charging happens during the idle time in the machine working cycle when it has stopped to wait for the container. Typical charging time in operation is 30 to 180 seconds, and with the maximum charging power of 600 kW, full charge can be achieved in a few minutes.”

“The Kalmar FastCharge solution consists of electric powered shuttle or straddle carriers and fast charging stations. Kalmar continues to test and verify the solution at the Tampere Technology and Competence Centre in Finland, with plans to bring the solution to the market during 2016.”

Dr. Tero Kokko, Vice President, Horizontal Transportation at Kalmar said:

“Customers have been asking for electric powered shuttle operation for a while already. This technology makes the charging process smooth, as there is no need to take the machine out of operation for battery swapping. Neither is there a need to invest in battery swapping stations and extra batteries.”

“Our hybrid technology has been extremely well received by the market. We have long experience in Lithium-Ion technology in hybrid machines, and this development is a natural next step in reducing emissions. This latest complement to our portfolio will provide excellent value to terminals which are facing even tighter environmental requirements.”

The next time someone claims that super-fast charging of EVs either isn’t possible or isn’t practical, we can just point to this.

One thing that is interesting about this system is that it has two charging cables (one black, one red) that more than likely plug into two onboard chargers. Each cable looks no bigger than a gas pump hose.

So even if you were to drop one of the cables and onboard chargers, if your battery size and chemistry were able to accommodate the charge, you would still have a 350 kW charge rate. At that rate you could completely fill a Tesla S90D in about 15 minutes.

Multiple charging ports on a car, and multiple charging cables, is one way to deal with the problem of the larger and stiffer charging cables needed for super-fast charging. But it’s hardly the most elegant one. I think future roadside super-fast chargers will have something like Tesla’s “solid metal snake” charging arm, or some sort of robotic multi-jointed charging arm. Of course, that will be more expensive than a charging cable you hook up like the self-service pump hose at a gas station.

If a charger is four times as fast, it is still cheaper if it cost three time as much. You also spare charging surface, which can be very expensive in cities.

I think that is will it will eventually got but I was referring to what is easily doable right now. One cable that can be as easily handled as a gas pump hose that gives you 350 kW is really good.

That looks like two single wire cables. The red one is the plus, the black one is the minus, just like for charging a 12 volt battery but here at 700 v and 1000 A.

Communication? Perhaps Bluetooth or as high frequency on top of the DC.

There are two strategies for recharging a bus. You either use a small rapid charging battery with many charge points along the route, or a large battery that you recharge at the end.

This would never charge a long range BYD bus in less than 30 minutes, and I doubt that the bus could handle even that charge rate. A typical Proterra bus would love it.

I posted this above. Here’s a passenger bus in China that is already charging at 700 kW. 350 kWh in 30 minutes is pretty damn good.


Well, they may charge quickly; but I have it on good authority that the straddle-carrier’s 0-100 km/h time is abysmal.

Not only that, it doesn’t have a fifth seat.

No falcon wing doors, either.

No Obsidian Black Metallic.

The people from the region of SmÃ¥land, Sweden where Kalmar lies are famous for being supereconomic (ehum, cheap) so it would be a safe bet that it’s a very economical solution too both to install and run.

Nice, anything which helps clean up emissions at our ports is very welcome.

Air quality problems there tend to hurt the weakest in society.

So when will we start seeing Fast Charge capable School Buses? Maybe Taxi Drivers would like this charging speed, too!

In the arena of fast charging batteries, some chemistries work better than others, for example, the 26650M1b cells, rated at 3.3V x 2.3Ah, can discharge at 30C, with Pulses up to 50C, but I think their charging rate is a bit slower at just 10C, which could mean in theory, a 6 minute fill up!

It might be possible that with some super cooling and other thermal control, you could push for 4 or maybe even 3 minute charges, but how much power would that take if they were used in a 250 mile range vehicle?

It would seem that container carriers like this probably push 3-4 Hours between breaks, but maybe only 50 to 80 miles in that time!

Can we get a diamond lane sticker for it?

Wouldn’t need cables if using third-rail type connections in the roadbed. A connector the size of a railroad track is pretty big.

How ironic. The city got one CHAdeMO charger and no Supercharger within 250km range

No details even in the commercial.
