Electric Car Batteries

SLOW CHARGING

Slow charging takes 6 to 8 hours to fully charge the electric vehicle (the time varies depending on the power available from the grid and the battery capacity).
 
Charging is performed with a power output of less than 10kW.
 
Charging times are calculated based on a battery capacity of about 15/20kWh and a slow charge with a single-phase electrical system with a capacity of about 3 kW.

QUICK CHARGING

With this type of charging, the electric vehicle is fully charged in about 2-3 hours. It works with a three-phase electrical system and a supply capacity of 22 kW.
 
This type of charging is normally available in the infrastructure installed in public places..

ENERGY FOR THE ENVIRONMENT.
Do cars pollute? Not electric cars if you choose EnelDrive, which helps you eliminate emissions, with energy from 100% renewable sources.
Not only will the air you breathe improve, but also your hearing, because electric cars halve the noise pollution around town.

FAST CHARGING

Fast charging works with a three-phase electrical system and charging times that are much faster than with the other systems.
 
The infrastructure that allows fast charging can be based either on alternating current or direct current.

Fast charging with alternating current (AC)

This AC charging infrastructure provides:
  • 43kW of power (three-phase)
  • a voltage of 400 V
  • 63 A of current
It was designed by Enel in collaboration with Renault, and the only vehicle currently on the market that allows this type of charging is the Renault ZOE.
This infrastructure can also be used by vehicles that do not permit fast charging, as it also provides charging at lower powers.

Fast charging with direct current (DC)

The most widely used fast charging system is that defined by the CHAdeMO standard (short for "CHArge de MOve"), named after the homonymous Association of Japanese origin.
 
This infrastructure includes a rectifier that converts AC power to DC power and provides:
  • 50 kW of power (three-phase)
  • a voltage of 500V
  • 100A of current
 

The CHAdeMO association

The CHAdeMO association was founded in 2010 by five of the most advanced companies in the field of electric vehicles: the Toyota Motor Corporation, Nissan Motor Company, Mitsubishi Motors Corporation, Fuji Heavy Industries Ltd and Tokyo Electric Power Company Inc – TEPCO.
The aim of the association is to promote the development of electric cars through the diffusion of fast-charging stations and standardisation of the associated technologies. In 2013, the number of stations with this charging system installed grew by approximately 100%: installations in Japan increased from 833 to 1,381, those in Europe from 158 to 601, and those in the United States from 12 to 154.
These charging stations currently serve more than 70,000 electric cars, i.e. over 90% of the electric cars on the market.

BATTERY SWAPPING

Battery Swapping is a recharging system and also a business model, designed by the Israeli company "Better Place", which made a deal with the Nissan-Renault car group.
 
It is a service for replacing a flat battery with a charged one, through infrastructure similar to that of a service station.
 
The process is fully automated, with no need for the driver to get out of the electric vehicle: a shuttle transports the vehicle into the infrastructure, a mechanical arm extracts the battery from the underside of the vehicle and replaces it with one that is charged. Once the battery is changed, the electric car can go back on the road.
 
The fundamental requirement for battery swapping to work is for most of the vehicles on the market to be compatible with the battery replacement infrastructure.

INDUCTIVE CHARGING

With this system, the charging process relies on electromagnetic induction, in which an electric current is generated by a variable electromagnetic field.
 
Charging is performed by aligning two metal plates, one at road level and the other on the underside of the vehicle.
 
The plate located in the ground is connected to the power grid and generates an alternating electromagnetic field through an induction coil. The electromagnetic field reaches the coil on the underside of the vehicle and generates an induced alternating current. When this current is converted into direct current, the batteries begin to charge.
 
This solution also minimises the environmental and visual impact of the charging stations, particularly in urban areas and city centres.
 
The efficiency of this type of charging is high (about 90%) but the disadvantage is that 10% of the energy is lost during the process of transfer between the transmitter and the receiver.
 
This technology is still at a trial stage: no technical standard has yet been established for the construction and marketing of the plates.
