Every car comes with a different type of battery, with capacities varying wildly. As such, there is no standard charging time. It also depends on the type of charger you are using. Level 1 household outlets take extremely long to fill the newer, larger batteries, which is why the newest electric cars usually come with dual charging cables, or the manufacturer might install a Level 2 charging unit in your home. This will usually take between six and 12 hours. Most public charging stations offer Level 3 fast charging, which can do the same job in as little as 15 to 45 minutes.
