ELECTRIC CAR: WHAT ARE THE ADVANTAGES?

TECHNICAL STANDARDS

  • How to recharge an eletric car?

    The charging of an electric car provides a continuing communication between the vehicle and station, to verify that in every moment safety conditions for the vehicle and people are respected.

    The Way 3 Charging will start only after this procedures:

    1. vehicle and charging stations connected by cable;

    2. a communication established between vehicle and charging station;

    3. verify safety conditions;

    4. From now, the system will be powered.

    If during the charging arise some problems(for example the cable brake or damaged), the system goes automatically in protection, cutting down the tension and so interrupting the charging flux.

  • What does the european standards provide?

    Charging of electrical cars is regulated by the European community to be the same in all Europe: the international standard IEC 61851 provides 4 way of charging, two of them specifically for domestic use, only if not opened to third people(Way 1 and 2) and two usable both in a public and private areas(Way 3 and 4). In particular way 3 is the more popular  for charging electrical vehicles, in public and private areas.

  • There are laws in italy which regulate electrical mobility?

    National infrastructure plan called PNIRE, which specify the guidelines to develop a charging system same in alla Europe, esteem that the charging point must be 1/10 of electrical vehicles.

  • Are there legal obligation for new construction?

    From Dicember 31 2017 Town Halls will establish that, for the houses and public buildings over 500 square metres,  there must be an electrical predisposition for possible installation of electrical infrastructures for charging vehicles.

  • How to recharge your car safely in public areas?

    You should verify that the charging station and the installation are corresponding to the standards. You have to pay attention because often on the market you could find products that don’t satisfy what prescribed in the national law about security.

  • Is it possible to use classic plugs to recharge in public areas?

    No. For safety reasons the law prescribes the use of connectors.

  • Are there adapters to be used for recharging in public areas?

    No, the law bans them.

  • How can i access to recharging service in public areas?

    The access to recharging services is covered by the service’s manager and not the producer of the station. Some managers utilize dedicate cards, subscription-paid services or by classic methods of payment (credit cards, token vending machine…).

  • Does it exist an ufficial mapping of all the stations in public areas presents in italy?

    A mapping does not exist yet. PNIRE (Infrastructures National Plan) provides the creation of a unique national platform where put all this information together but currently is not active.

TIMES AND COSTS OF CHARGING

  • How much autonomy does it have a electric car?

    The autonomy depends above all on the capacity of the battery. Said that, you need to consider that typically you don’t need to recharge the car only when it is completely low batter, as that not always the charging finishes at 100%. Is important to consider that the 80% of the charging is obtained in an half of the time necessary for a total charging. 
    Car manufacturers provides in a booklet the details of the car, among them also its autonomy.
    It is important to take account  there are many factors that can affect the autonomy, among them how it is drived, environmental factors (winter/summer), usage in urban or suburban areas.

  • Which factors influence the charging?

    Contrary at what it is thought, the power of the charging available is not the only factor that establish the charging times. In fact, the most important one is the car, since that according to its absorption capacity and the security system on the charging control, determine the quantity of energy taken up. The quantity of energy available becomes important only after that.

  • Rapid charging can damage the car?

    Some manufacturers don’t advise a frequently usage of this type of charging but only when really necessary.

  • Which are the charging costs?

    The charging  costs depend on different variables: charge provider, energy provider, type of contract, type of car, time band. AEEGSI specify  which are the fares applicable at usage of electrical energy depending on terms of the contract, in case of one-hour/two-hour fare.

    Below we can see what is the average cost in bill for customers with contracts starting from 3kWh, one-hour/two-hours slots.

    In this chart the cost is in kWh and specify the cost of a average family, so: power 3kWh, contract of electrical supply for single-family house, consumption of 2700kWh per year, without taxes:

    One-hour slot Two-hour slot (F1) Two-hour slot (F2, F3)
                  0,171232 €/kWh 0,176772 €/kWh 0,168432 €/kWh

    So, how much does it cost an electric car?
    Considering that an average usage is 14,10kWh/100Km is easy to understand: only for electricity, an electric car costs 0,92€ / 100 Km during the one-hour slot and 0,84€ / 100 Km during the two-hours slot and night. This costs implies total efficiency of the battery and the system of charging, without leakage.
