Preconditioning an EV refers to the practice of preparing the vehicle's battery to improve the range and efficiency of the EV. This is especially helpful in extreme weather conditions (hot or cold).
To precondition your EV, you may find it easiest to use the manufacturer's mobile app to remotely set/control the vehicle's interior temperature.
Cold Weather Preconditioning:
While the EV is still plugged in to a charger and you're preparing to leave, use the EV manufacturer's mobile app to heat the cabin (and the battery) to a comfortable temperature.
Preheating the battery and cabin while the vehicle is still connected to a charger, uses less energy from the battery during your drive, resulting in better range.
Hot Weather Preconditioning:
In hot weather, preconditioning may involve cooling down the cabin to a comfortable temperature before you start driving. Similar to cold weather preconditioning, use your EV mobile app to turn on the AC while the EV is still plugged into a charger and before you leave.
This can be particularly helpful in EVs with larger battery packs, as cooling the cabin while the vehicle is still plugged in can prevent the battery from overheating during your journey.
