BVS Future Charging Point Publication
Posted: Tue Jun 17, 2008 5:25 pm
Hi,
I am updating John's charging point installation leaflet to enable it to be used for my local council who I am working with. It can then also be used as a proper BVS document that any BVS member should be able to used.
I would like to complete this as soon as possible so any tips, information would be greatfully received.
Regards,
Rob

ELECTRIC VEHICLE PUBLIC CHARGING POINT ASSESSMENT AND IMPLEMENTATION
(Battery Vehicle Society)
INTRODUCTION
For various reasons (e.g. fuel prices increase, decrease in oil availability and wider deployment of congestion charging) more and more people are choosing to purchase and use electric vehicles. This document summarises the advantages/disadvantages of supporting the use of electric vehicles in city/town centres and at work. It covers currently available options with costs and makes a recommendation for a typical installation.
ADVANTAGES OF SUPPORTING ELECTRIC VEHICLES
The following summarises the advantages and disadvantages of installing a recharge point:-
Advantages
* Installing a recharge point at work effectively allows 4 times the number of people to use electric vehicles to travel to work [1]
* Installing a recharge point in a shopping centre means at least 50% more people can use electric vehicles to shop [2]
* Charging at work and shopping centres is part of the Project Better Place that ?? governments are currently interested in adopting [3]
* Provides visible evidence that a city/town/company is actually supporting green travel
* currently a 50% grant available for the installation of publicly accessible charging points, although many installations are performed without grant assistance due to the administrative burdens involved for low cost installations [?]
* Electric vehicles are ideal for local commuting including to work and for shopping.
* Reduces particulate pollution in towns and cities.
* Reduces carbon footprint for each local trip using an Electric Vehicle by 60%
Disadvantages
* High initial costs of installation compared to the amount of electricity that is used and can therefore be charged for.
* Increases pollution at power station by increased electricity usage while fossil fuel power stations are used. However, this can be mitigated by installing solar cells locally (however this significantly increases the costs, e.g. £10k for a solar cell array to fully cover a few electric vehicles)
CHARGING MODEL
Many charging points either do not charge for the electricity, or have a charity donation box because the annual cost of electricity is small compared to installation or administration costs. The typical cost of electricity for a car using the charging point will be about 50p for a 2.5 hour recharge. For regularly used commuting charging points in London, this could amount to £100 pounds per year, but elsewhere without congestion charging incentives for electric vehicles, the electricity cost will be much less.
RECOMMENDED INSTALLATION
There are several options for electric vehicle recharging points, of varying costs and practicality. The following covers the key points.
Recommended Approach
* A problem with connecting/installing one vehicle should not cause a problem with another one already on charge. This is because it can be extremely inconvenient for the affected driver when he gets back and expects his vehicle to be adequately charged.
* Vandals should not be able to disrupt charging of vehicles on charge.
* Support of 16A sockets (operating at 16A) as some electric vehicles (e.g. the common Berlingo Electrique) will take the full 13A or slight over causing warming of any 13A plug and cable (not ideal from a safety point of view).
* All charging points should have weather protection, an isolating switch and a residual current device for safety.
* It is recommended that installation of outlets are in pairs, as the installation and cost of security measures, if necessary, far exceeds the cost of a second socket and isolator.
Recommended Installation
* One RCD per outlet (at an additional cost of £??) see Recommended Approach ? & ?
* 2 outlets per post (this minimises installation cost)1
* 16 A outlets.

EXISTING SITES
See www.ev-network.org.uk for public charging points.
London Computerised Charging Points
In London, computerised charging posts are installed, for which grants are available to reduce their installed cost of £12,000 each. These charge an annual membership of £400 and provide their electricity for free. They are activated by a radio card which is provided free with annual membership. This system is best suited to a commuter environment where the charging points are used on a regular daily basis by regular users. The connections are via a lockable flap, and the charging plug is a standard domestic 13A 3-pin plug.
Bristol
In Bristol, publicly accessible charging points at present are within shopping centres and private businesses. At the Cribbs Causeway shopping centre, four unlockable recharging sockets are provided under cover, two 13A weather resistant domestic sockets and two 16A external sockets. The underground car park has CCTV coverage and is open 24hrs per day, as the shopping centre police are stationed nearby, and they can be used 24hrs per day, although people using the facilities are asked to sign a register each time they use them, and make a charity donation for the electricity they use during shopping centre opening hours. They are regularly used by cars, vans and motorcycles, and they also provide other free recharging facilities for electrically assisted bicycles. Other Council or private recharging facilities are open to the public and provide either 13A or 16A external weather protected sockets. Some ask for a contribution towards the electricity costs, some do not. Some are accessed only by permission from administrative staff, and some have combination locks on them, so that regular users do not need permission or the presence of staff to operate them.
Germany
In Germany, there is a national recharging system, similar to the old "AA box" system in the U.K. For a small sum, a key is provided that will open any box throughout the country for the registered user.
--------------------
[1] Allowing people to recharge at work means that they can travel double the range to commute (doubling the radius, doubles the area of a circle). So the number of people that this then covers is the square of 2, which is 4.
[2] Assuming that the standard car takes 8 hours to recharge and most people spend 2 hours shopping, then the increase in range is 2/8 = 0.25. The number of people affected is 1.25 x 1.25 = 1.56
[3] Project Better Place plans to deploy an extensive network of 500,000 battery charging spots in Israel which is part of a national scheme for an electric vehicle infrastructure that is both practical and appealing to governments (see presentation on Youtube by ?? at http://tinyurl.com/6653rt). As of ?? 30 ? governments have shown interest in adopting the model. Including charging points at work and in shopping centres are an important part of that model (see ??? for more information).
