How long does it really take to «fill the tank with electricity» under my own roof? Car manufacturer brochures get convoluted. Let's remove the makeup and present it pragmatically, as we at the Serenovables analysis delegation love to illustrate.
We will calculate on the fly applying the typical realistic Spanish assumption: installing on a single-phase wall with adjusting contracted power at night resulting in an injection limit of 7.4 kW.
Let's imagine recharging from empty (10%) to the highly recommended daily full (80%) on the two most representative batteries on our roads:
- Small Citizen-type battery (e.g., Dacia Spring, Renault Twingo, or R5): featuring a capacity of roughly 30 kWh. Subtracting tiny heat leaks, we require only around three to four exceedingly short hours.
- Strong sedans or standard SUVs (e.g., Tesla Model 3 Standard or a VW ID.4): capacities spanning up to the 60 kWh bracket. Replicating the same injection, we generally require around a solid 6 to 7 flat hours.
In both paradigms, this displays complete compatibility with the habitual "8 or 9 static hours" generated by resting in our beds while sleeping. Arrive, plug in the hose within four literal seconds, go to bed relaxed, and return to work early the next morning as the absolute master of your power supply.
