How Are Electric Vehicles Charged?
Before buying an electric vehicle it is essential to gain familiarity with the necessary on-board equipment to prevent “charging” or, to use a current term, “top-up” problems.
It is important to check that the electric vehicle is fitted with a battery charger with a “standard” connection, i. e. suitable to draw electrical energy directly from ENEL’s grid and therefore from the power outlet in our garage. If it’s not then there is something wrong and you need to contact the seller.
This solution in the standard equipment fitted on an electric vehicle allows to charge the batteries in any place with mains electricity. Indeed electric cars have other various types of battery chargers. However, these do not allow to draw electricity from the mains supply but need special adapters or need to be connected directly to the charging points in service stations now available in large towns. The ideal solution is to have a battery charger on board the car with a high-frequency standard socket without the need to resort to external devices.
When taking into consideration an electric vehicle one needs to examine the costs to bear for the energy required to power the set of batteries. Models that allow to reduce energy costs are definitely the ones that allow to charge the batteries directly from the national domestic mains supply. Usually a full energy charge for a complete set of traction batteries for vehicles that draw energy directly from the mains supply does not cost more than 2 euros.
Vehicles fitted with a standard battery charger allow to optimise the time spent at home to charge the batteries. Indeed on average it takes 8 hours to fully charge a set of traction batteries. We recommend charging the entire set of batteries overnight, after the vehicle has been used during the day, in conjunction with the cheapest electricity tariff. It is also possible to charge the batteries for less time during the day for partial charges.
Partial charges do not result in problems affecting the runtime and/or efficiency of the set of batteries, as they are not subject to the memory effect. Precisely because they do not suffer from the memory effect, the set of batteries of electric vehicles has an average life of about 4 years.
A fully charged set of batteries of an electric vehicle allows for an uptime that varies between 70 and 100 km, depending on the model and set-up selected.
