Another option is the Tempo Happy tariff, which allows you to choose any two hours of the day in which your electricity will cost 0 euros, so you can charge your vehicle during those hours. However you will need a fast or semi-fast charging system in order to allow you time to charge your battery during those hours.
Lastly, if you have a time restriction tariff, it is best to charge your electric vehicle at night, when electricity is cheaper. But beware, the “off-peak” time interval in which electricity is cheaper may vary. Generally speaking, in summer it is from 23:00 to 13:00 and in winter it is from 22:00 to 12:00. This gives you enough time to fully charge your car’s battery conventional charging, the slowest system, which takes approximately 8 hours).
If you have the “super off-peak” tariff, the cheapest interval will be from 07:00 in summer and in winter. With this tariff you will spend €1.55 for every 100 km covered, compared with the €7.79/100km minimum cost of combustion engine vehicles. You can also use the charging points located in public spaces.
