As an expert in the field of electric vehicle charging, I'd like to provide you with a comprehensive answer regarding the charging time of a Tesla at home.

Charging a Tesla at home is a different experience compared to using Tesla Supercharging stations. Home charging is designed to be a more convenient and slower process, allowing you to charge your vehicle overnight or during periods when you're not using it. The charging speed depends on several factors, including the type of charger you have installed, the electrical capacity of your home's electrical system, and the specific model of your Tesla.

Firstly, the type of charger is crucial. Most Tesla vehicles come with a Mobile Connector that can be plugged into a standard 120V or 240V outlet. However, for faster charging at home, Tesla recommends installing a Wall Connector, which is a 240V charger that can deliver up to 40 amps of power. This setup can provide up to 32 miles of range per hour of charging.

Secondly, the electrical capacity of your home plays a significant role. If your home is equipped with a 100-amp electrical panel and you have a dedicated 50-amp circuit for the Wall Connector, you can achieve faster charging rates. However, if your home's electrical system is not designed to handle such loads, you may need to upgrade your electrical panel or work with an electrician to ensure safe and efficient charging.

Thirdly, the model of your Tesla affects the charging speed. For instance, the Tesla Model S and Model X can accept more power than the Model 3 or Model Y, which means they can charge faster when the conditions are right.

In terms of actual charging times, with a standard 120V outlet, you might only add about 2-3 miles of range per hour, making it impractical for most daily use. A 240V charger, on the other hand, can add about 30 miles of range per hour, which is much more practical for overnight charging. With a Tesla Wall Connector, you can expect to add around 80 miles of range per hour, which is significantly faster.

For example, if you have a Tesla Model 3 and you start with a completely depleted battery, charging overnight with a Wall Connector could potentially get you to 80% by the time you wake up, assuming you start with a nearly empty battery. This would be enough for most daily commutes and errands.

It's also important to note that charging rates can slow down as the battery gets closer to its full capacity. This is due to the battery management system's design to prolong the battery's lifespan. Therefore, the last 20% of the charge may take longer to complete.

In conclusion, while home charging is not as fast as Tesla Supercharging stations, it is designed to be a convenient and efficient way to keep your Tesla charged for daily use. The actual time it takes to charge your Tesla at home will vary based on the factors mentioned above, but with the right setup, you can expect a full charge overnight or within a few hours.

From zero to 300 miles would take about 52 hours at that rate. With a single onboard charger connected to a 240-volt outlet, which Tesla recommends, the pace can reach speeds up to 31 miles of range for each hour of charging, meaning a full 300-mile charge takes less than 9.5 hours.read more >>
