At regular charging stations, such as those at public charging points or home chargers, it is generally safe to remain seated in the car during charging. These charging stations are designed with safety measures and comply with applicable standards.

However, it is always advisable to follow the instructions of the specific charging station and the manufacturer of your electric car. Some charging stations may require specific safety measures, such as turning off the car during charging or not leaving the vehicle unattended.

Additionally, it's important to remember that fast chargers often use higher currents than regular charging stations, and your car may become warm during fast charging. In such cases, it is usually recommended to step out of the car during fast charging as a precaution to reduce the risk of overheating.

In short, as long as you follow the instructions of the charging station and the manufacturer of your car, it is usually possible to remain seated in the car during charging.
