It depends on the output level and the car you have.
For example, The battery capacity of the Tesla Model Y Long Range Edition is approximately 75kWh.
Assuming we want to charge from 0% to 80%, which means we need to charge 60kWh of electricity
Using a 3.5kW charging station for charging theoretically takes approximately 17 hours
However, the actual charging time may be influenced by various factors, including the temperature of the battery, changes in battery efficiency during the charging process, and nonlinearity of the charging curve. Especially when the battery is close to full charge, the charging speed will slow down to protect the battery and extend its lifespan. Therefore, the actual charging time may be slightly longer than the calculated value.
We have a blog post that focuses on the issue of charging. If you are interested, you can read it here.
