World’s First Portable EV Power Unit On Sale Now

JUN 15 2012 BY STAFF 16

A Nissan LEAF That Came Up A Touch Short Gets A Boost

Potentially eliminating the need to have tow trucks come and rescue electric vehicles that have fallen just short of their destinations, a British company has announced that the “world’s first totally portable EV power” station is on sale now.

Charging Solutions "EV Rescue" Unit

The unit is customized to recharge electric vehicles, with a J1772 charging connection that plugs into any EV’s standard level 2 connection.  The Powys-based company says that it can charge a 2011 LEAF at the rate of 1 mile per 3 minutes, and the new 2013 LEAF (with the upgraded 6.6kW onboard charger) at 1 mile per minute.  The standard version can recharge most electrics (Volt, LEAF, Focus) with a boost equal to about 15 miles, with the deluxe putting out around 35.

James Jean-Louis, managing director at Charging Solutions that makes the innovative new product said, “The EVRescue is an innovative, standalone power unit for roadside assistance, remote locations, dealerships and repair facilities. Connect it to mains power, and it acts as an EV charger for showrooms, car maintenance and distributors, exhibitions and forecourt, providing flexible portable power without the need for fixed charging points.”

The unit comes in either a 4 kW or 10 kW version, and doubles as a standard charger when connected to the appropriate grid connection.

This unit makes a lot of sense for tow truck drivers to keep in the back of their rigs, dont think it is cheap or light enuf to have for personal use, but some might keep this in their trunk kind of like a towable generator.

How much does this thing weigh? I’d imagine this on a service truck, rather than having people haul this in their cars…

For sure a person could only hand the 4 kW-& that would be about 70 lbs, the 10 kW would be over 200

This highlights the pure EV weakness if it’s your only car….range anxiety.


While the EV infrastructure and battery technology evolves, such solutions help. If one suffers from range anxiety, buy a Volt. I did. Now you carry your generator everywhere you go and still enjoy a quite nice EV.

None of these numbers add up. 10 kW adds 1 mile/minute? That means 60 miles in an hour. 10kW for an hour is 10kWh. That implies the Leaf travels 6 miles on a kWh, which it does not. Also, how can you force 10kW into a car with a 6.6kW charger in the first place? And there’s 90 minutes for a full charge when connected to a 240V/13A supply (3.12 kW). The supply will add 4.68kWh in 90 minutes. Does that mean the battery in this thing holds the other 16kWh? If so, this flies in the face of the “15 miles of range when charged” number. A Leaf can go far more than 15 miles on 16kWh (although not the 96 miles it would if it got 6 miles per kWh as calculated above).

Clarification, please!

Just putting in my 2p. The pdf is worded oddly form the company, maybe how they do things in the UK?

I think what is being said is the standard unit can disperse 4 kWh of power before it is toast/out of juice….4 kWh is about 20% of a full charge in a LEAF, so 20% of 73 miles EPA = 15 miles. The 4 kWh/10 kWh is a reflection of storge capacity, not discharge rate.

I don’t know about that 1 mile a minute. As a wag, I think they are just trying to express that it flows at a normal L2 (what they call type 2) rate in the field? And did the math as 1 miles worth of charge aevery 3 minutes in a current LEAF, which still seems a tad fast in my mind…unless you are driving ultra conservatively once you get your charge.

Why they can’t just say it charges just like a regular 240v outlet in the field, I don’t know.

The article clearly states “The unit comes in either a 4 kW or 10 kW version, and doubles as a standard charger when connected to the appropriate grid connection.” If it should say 4 kWh or 10 kWh, then please fix it. There is a big difference between kW (power) and kWh (energy). It bothers me when commenters get these mixed up. A reporter, especially on a site like, needs to be even more careful.

The current Leaf’s L2 rate is 3.3 kW which is 3.3 kWh in an hour. The article states “it can charge a 2011 LEAF at the rate of 1 mile per 3 minutes”. This is 20 miles in an hour. If this is true, that means the the Leaf gets 20 miles in 3.3kWh, which is still 6 miles/kWh. I have never acheived over 5 miles/kWh in mine (and that was driving pretty conservatively). My lifetime average is 3.8 miles/kWh.

Heeh, I don’t know Brian. Hard to change it on this end (at InsideEVs), because as I read Charging Solutions PDF, that is how they have reported it (as kW), and those are the charging times they stated. Same with the math, I agree it seems about 20-25% too aggressive.

I could change it to make logical sense as you and I understand it probably should be…but that would be speculation, and perhaps could be inaccurate, which would be worse (which is likely not the case). Kind of a catch-22 here.

I agree the way the company has put out this information on the pdf is confusing to say the least. I think we just have to go with the fact this company has put out a portable charging lithium deck, and if you run out of juice, after XXX/some period of time your going to have about 15 more miles of range and leave it at that, (=


Oh, and if the unit does hold 4 or 10 kWh, the “full charge in 90 minutes” makes even less sense. There’s no way that you can pull enough energy from the 240V/13A supply in 90 minutes to supplement this unit (you would only get 4.68 kWh)

Again, weird pdf. Might be they mean the charger’s 4kWh lithium platform can be fully charged in 90 mins. That seems reasonable.

I think there is an intern or something working their PR.

“I think there is an intern or something working their PR.”

I had to laugh at this 🙂

Overall, I think this could be a great product, especially for service vehicles, tow-trucks, AAA, etc. Rather than someone coming to you with a gallon of gas, they bring this little guy and give you 15 miles to get to an outlet. The company definitely needs to clarify the specs though. Being relatively new, most consumers are in the dark wrt EVs. It is all of our jobs to be clear and speak a consistent language so that the mainstream consumers have a shot at understanding (and hopefully joining) our world 🙂

Hi all

It appears the spec may be somewhat lost in a US/UK translation, as the pdf was written by the company. It’s on the website at

Email and sure James will be able to help. The product was launched this month and has already received orders from the US.

The intern or something 😉

And what’s the price range?

Starts sub £8,000 GBP, if that helps.

How can i purchase a unit?
