PARVE Charging System Article
PARVE, which suggests something small or bird-like in Spanish comes from Punto Automatizado de Recarga para Vehículos Eléctricos and which in English sounds like the French word pavé and has been expressed as Park And Recharge Point for Vehicles: Electrical control and monitoring Equipment The first public  demonstration unit was an  Arduino controlled  socket  which was installed outside Cristalbox workshop at the Burgo shopping mall in Las Rozas Spain on the 3rd September 2012. It can be activated by registered users of the '[http://www.emovil.org/web.inicio? emovil]' web page which requires a deposit of 5 euros

It consists of a linked series of open source standards first proposed in Madrid, Spain, in June 2009 as a response to the OScar (open source car) initiative.

Essentially the standards relate to the implementation of control and monitoring of standard electrical power sockets in public places that are not ordinarily connected but which can be activated or disconnected by mobile cell-phone signals. Finally, the system will send a message indicating the quantity of electricity used (in kilowatt hours and the cost of electricity.

Design philosophy
The advent of smart grid technology and domestic photovoltaic installations selling small surplus power, combined with the need to develop alternatives to conventional transport fuels may signal the need for many, cheap, and widely distributed electrical recharge points. The 'recharge point' part of this system can be built by electricians without special 'electronic' skills using widely available components.

System Specification
Extract from the open source draft English version of the PARVE system specification

Local system for PARVE sockets in car-parks, exhibition halls, leisure parks etc. Service controllers for automated systems serving PARVE outlet facilities Suppliers and consumers legal and practical human relationships
 * PARVE mains electricity to outlet socket connection relay and current sensor
 * PARVE socket analog to (computer) digital interface converter with optional line driver
 * PARVE local server (basic computer hardware with PARVE input facilities and internet connection, typically by integral mobile cellphone)
 * PARVE service controller software system (local server and remote control programmes)
 * PARVE defined system interface definitions and signalling standards
 * PARVE billing and roaming policies (inter-operability standards for local PARVE host organizations the various electricity resellers
 * essential contract conditions (legal obligations &  public safety requirements) for PARVE providers and end-users such as private owners of electric vehicles, operators of amusements in leisure parks etc.
 * Mobile cellphone or internet terminal applications to assist users to correctly input the unique PARVE outlet socket location identity to the automatic service controller via 2-d data labels bar-codes, or manual input devices.

PARVE Connector Relay + Sensor unit
Initially a relay-sensor (called relesensor unit) is installed as an accessory in a standard electrical socket outlet. This has a 5volt TTL 'on' signal input, and a 0 - 5v analog electrical current monitor. The unit can be constructed by any competent electrician using components costing about US $20 and a soldering iron.

These signals are ordinarily connected to a computer server which runs the PARVE local control software. However any computer (such as a hotel receptionist system) connected via an external (USB) analog interface unit or even a simple switch and multimeter could be used. The maximum probable range (analog cable length) is about 300 meters.

PARVE Local Server Unit
The PARVE server (which is a PC motherboard and peripherals with no external controls) uses a mobile cell-phone to connect to the internet and communicate with the control center. The user interacts with this center via a mobile cell-phone using secure standard internet signaling techniques. The estimated component cost is around US $150
