Chargemaster intends to install up to 200 DC fast chargers in London by 2017, according to EV Fleet World.

It’s expected that the first 30 will be launched in the second quarter of 2016.

A few months ago, Chargemaster unveiled the Ultracharger – 50 kW multi-standard DC fast charger.

This new project will be funded by Chargemaster and its private sector partners without government subsidies.

They will be offered free to site owners, to be installed at short-stay locations such as supermarkets, petrol stations and public car parks, and the network will utilise the manufacturer’s new UltraCharger, which offers compatibility with the three most common charging standards used in the UK.”

According to chief executive, David Martell, London is “crying out” for fast chargers (12 are available in the city center as of today).

London’s Ultrachargers will be integrated with Chargemaster’s POLAR charging network, which offers a membership option, as well as a pay-as-you-go option.

“Martell added that, although the points will be part of the company’s POLAR membership scheme, other drivers can use them on a pay-as-you-go basis, charged to a credit or debit card. Members will be charged a lower rate per kilowatt-hour than they would to plug in at home. The aim is to have 50 installed by the end of 2016, with the potential to have 150 and 200 online by the end of next year.”

    Looks and sounds cool, though that particular installation needs a curb around it, or someone will back right into it.

    Design should presuppose incredible stupidity on the part of prospective users.

    I’m puzzled… could someone explain how a Zoe and a Tesla MS use the same plug?

    1. Will says:

      I am not sure either as Telsa use a proprietary connector.

      1. Just_Chris says:

        I believe the charger has a high powered AC connection for those 2 vehicles – not really fast charging for a Tesla as it will only use its 10 or 20kW on board charger but the Zoe can draw up to 43 kW depending on the age/model year of the vehicle.

      2. zzzzzzzzzz says:

        Tesla uses Type 2 compatible connector in Europe.

    2. Hardcore says:

      This particular fast charging unit seems to offer universal support (via 3 different connectors). The Zoe uses one of them and Tesla offers an adapter to enable 50kW charging using another. All in all, this seems like a good choice to install.

      However, there are rumours that several of the charging standards will soon see upgrades to 150kW power delivery, which would make these units obsolete.

  3. Will says:

    50 kW… so charge a Leaf or i3 in around half an hour. Charge a Model S 90 in just under 2 hours. Or in other words it charges ~2 miles per minute for most drivers.

    I think the sweet spot – the point where we say ‘this is fast enough’ – is going to be around 200 kW. With that you can almost guarantee to fully charge a P90D pack in 30 min. Works out at ~8 miles per minute, that’s plenty.

    1. Just_Chris says:

      London (as in the bit in the M25) is only about 30 miles across with central London being less than half of that. High powered charging might be needed for road trips but would (IMO) be pointless in a dense city like London I’d rather have 200 fast chargers at 50kW spread across London where driving 10 miles could take 40 min rather than 50, 200kW chargers.

      1. I think there’s another angle. There’s almost no offroad parking for residents in London. However, it becomes practical to own an EV if, say, once a week you could fully charge it at a local rapid in half an hour.

    Fantastic initiative! Things are starting to get realy serious!

    Will,

    If you want to calculate chargetimes, you can’t just take the battery capacity (in Kwh) , and divide it by the chargerate capacity (In Kw). The chargecurve for Lithium batteries is not straight.
    E.g. The 90Kwh Tesla battery might initially charge at say about 45 Kw, but will soon (after 10 or so minutes) start to slow down as it creeps up to nominal voltage (maybe 3,8V/cell or so, depending on the chemistry.), and will eventualy go into saturation charging, where the amperage will decrease in order to keep the voltage in
    check. as you go beyond about 85% usable charge, there will be a much more drastic decrease in charge rate. So the average charge rate from 0-100% capacity on a 50 Kw charger might only be about 35-40 Kw for a very big battery like the Tesla’s 90Kwh one, and as low as 20-25 Kw for a “smaller” battery like the i3’s 22Kwh one. So from 0-100%, you are looking at total charge times of about 2,5 hours and 1 hour respectively on the said 50Kw charger.

    I am by no means a battery expert, but that’s how I understood it. Please do correct me if I am wrong.

    1. I think you overstate it. My Renault ZOE, for example, charges at 43kW at full speed to about 90%, and even then tapers off only a little (perhaps to 30kW). I can get a full charge theoretically in half an hour, in fact it takes about 35 minutes.

  5. Fred Borloo says:

    And I think Just Chris is right, up to a point.
    The charge rate capacity of the charge points should be adapted to two things:

    -How big the battery is you are going to charge (i.e. The state of the art of batteries withing the lifetime of the charger. E.g. The “affordable standard” for most EVs used to be about 20Kwh, but with the Bolt and Model III this seems to be increased to 50-60Kwh!)

    -How long the user will be willing to spend time at the charge spot. E.g. 1-2 hours at a supermarket, 15-30 minutes at an enroute gas station or 8-12 hours overnight or at the workplace).

    It is very important to initaly spread the charge rates out over time and eventually to use (overnight) buffer capacity and smart charging in order not to overload the net. Just take a calculator and calculate how many Gigawatts we would need to charge all the cars in the UK overnight at just 5Kw! Isn’t going to work if they would all decide to plug in at the same time!!

  6. martinwinlow says:

    (Sigh…!) They are RAPID chargers NOT FAST! That’s something else.

  7. Motarra says:

    Slow AC charging at home/condo/flat/apt. 50kW metro. 150kW+ supercharging at the edge and between metros. Pretty straightforward network design right?

    It would be fantastic (and profitable) if the OEMs, utilities, investors and governments could cooperate and get that done. But alas they will instead spend their efforts creating roadblocks for one another. The oil producers don’t really have to work all that hard to slow down the growth of charging networks. The parties listed above are taking care of it for them. Tesla and Nissan being the notable exceptions.

    If only they could build 200 quick chargers in the North East or Virginia.
