Tesla requires approximately 68 to 80 kilowatt-hours for a full charge, which can provide a range of 500 to 600 kilometers. Tesla offers three charging modes: home charging using Tesla's dedicated charging pile, which can charge at 74 km/h and takes about 6 to 7 hours for a full charge. If using a national standard fast charger at a gas station, the charging speed reaches 250 km/h, typically taking two to three hours to fully charge the car. With Tesla's super-fast charging pile, the speed reaches 700 km/h, usually requiring only one hour for a full charge. Tesla features an automatic power-off function; once the vehicle is fully charged, the charging pile will automatically cut off the power. Leaving a Tesla charging overnight without unplugging has no impact. However, it's important to note that Tesla's supercharging piles now impose an idle fee if the vehicle is not moved within 5 minutes after charging is complete. Tesla vehicles are designed for braking stability and smoothness, maximizing the recovery of braking energy to extend the electric vehicle's range. If charging is limited to 80%, the energy recovery braking function can feed braking energy back into the battery, allowing the vehicle to start with more than 80% charge—possibly 90% or even 95%. However, if the battery is fully charged to 100% before use, the regenerative braking system cannot recover energy until the battery's charge drops to a certain level, preventing the battery from gaining additional energy.
