ELECTRIC VEHICLES (EV)

Technical characteristics and requirements of electric vehicles (HEV, PHEV, BEV, FCEV)

Electric vehicles require an electric motor powered by batteries that are recharged using the electric power network.

There are four types of electric vehicles:

  • HEV (Hybrid Electric Vehicle): vehicle which combines a conventional internal combustion engine propulsion system with an electric propulsion system.
  • PHEV (Plug-in Hybrid Vehicle): hybrid vehicle which uses rechargeable batteries that can be restored to full charge by connecting a plug to an external electric power source, such as recharging stations or the general electric power network.
  • BEV (Battery Electric Vehicle): vehicle powered exclusively by a battery that can be recharged using the electric power network.
  • FCEV (Fuel Cell Electric Vehicle): vehicle powered by a fuel cell by means of a chemical reaction between the hydrogen stored and the oxygen in the air.

5 reasons to use an electric vehicle

Clean air

The electric vehicle produces 0 pollutant exhaust emissions

Noise

Electric vehicles require less maintenance even if it is more specialised and the energy cost is lower.

Recharging infrastructure

Electric power network easy to access and with a wide offer of public charging points

Aids and incentives

There are benefits and help for the acquisition and use of an electric vehicle

NATURAL GAS VEHICLE (NGV)

Characteristics of Natural Gas Vehicles (NGV)

The difference between natural gas (NGV) and the gas we use in our homes is that it is used in two ways: compressed natural gas (CNG) at 200 bar, which is mainly used in light vehicles for any kind of route and in heavy vehicles for urban and suburban routes; and liquefied natural gas (LNG), which is in liquid phase and is mainly used in long-distance lorries.

The vehicles with NGV technology require a combustion motor that, at the same time, thanks to the technology of the manufacturers, allows them to operate on a bi-fuel (NGV or gasoline) or dual fuel (NGV plus diesel oil) system.

There are two types of stations depending on the fuel you want to supply: compressed natural gas (CNG) stations, which can be fast or slow-charging stations; and compressed natural gas and liquefied natural gas (CNG-LNG) stations, in which the recharge time is never over 10 minutes. There are also mobile LNG stations, in which a lorry has a built in deposit with a pump. These stations are useful to study the potential of an area before building an actual station.

5 reasons to use the NGV

Environment

14093140180_40cc891232_b

Reduces the emissions of carbon dioxide, nitrogen oxide and particles

Noise

14093140180_40cc891232_b

Significant decrease in noise emissions and engine vibrations

Savings

14093140180_40cc891232_b

Up to 50% of the fuel cost with relation to a conventional vehicle

Range

14093140180_40cc891232_b

Longer range of NGV thanks to the bi-fuel and dual fuel systems

Adaptability

14093140180_40cc891232_b

Availability of the technology for different vehicle segments, from private cars to heavy goods vehicles and ships
