Is the last charging time displayed on Tesla accurate?

The last charging time displayed on Tesla car is relatively accurate.

The charging session display of Tesla vehicles usually provides some key information, such as charging time, charging amount and charging speed. These data are recorded and transmitted through the vehicle's battery management system and charging equipment.

The battery management system of Tesla vehicles has been precisely designed and calibrated, which can accurately monitor the charging and discharging process of batteries. When the vehicle is charging, the battery management system will record the start time and the charging amount, and display it in the charging session of the vehicle after the charging is completed. These data are usually reliable and can help car owners understand the situation and effect of charging.

However, there may be some errors in the charging session display of Tesla vehicles. For example, due to the failure of the charging equipment or vehicle, the charging session may not accurately record the charging time and amount. In addition, special charging conditions, such as fast charging or using third-party charging equipment, may also lead to inaccurate data of charging session.
