How many degrees below Tesla should be preheated first?

When the outside temperature is as low as zero, an orange warning button will APPear in the Tesla app to ensure that the trip has all the electricity. The preheating process should be started 1 hour in advance, and Tesla suggested that it is best to plug in the preheating to reduce power consumption. Electric vehicles need a certain amount of energy to maintain a suitable battery temperature. If you need to park the vehicle for a long time, please plug in the charging power supply to avoid power consumption when parking.

Preheating introduction

It can ensure that the vehicle is fully charged when driving again. There is no limit to the time when an electric vehicle is connected to the power supply. With the support of perfect fault diagnosis technology, our electric vehicles are equipped with intelligent protection measures, so we don't have to worry about overcharging when connected to the power supply for a long time.

In cold weather, the battery efficiency of electric vehicles decreases, resulting in a sharp decline in vehicle life. This is well understood by riders living in the cold north, so Tesla's reserves have not been as good as those in the warm southern cities.

In order to maximize the discharge of battery power, maximize the recovery of kinetic energy, or maximize the charging efficiency in extremely cold weather, Tesla's battery management system needs to heat the battery pack, which itself needs to consume a certain amount of battery energy, which also leads to the decline of battery life.
