how long does it take to charge an electric car at a public charging station

How long does it take to charge an electric car at a public charging station? The time required to charge an electric car at a public charging station varies depending on a variety of factors. Here is a detailed analysis of these factors:

I. Charging method

1-1. Fast charging:

Generally, high-power DC fast charging can charge 80% of the battery capacity in 30 minutes and fully charge in about an hour. However, please note that to protect the safety of the battery, the charging current will decrease after the power exceeds 80%, so it will take longer to charge to 100%.

For example, a 60kW DC charger can usually fully charge an electric car's battery in less than an hour.

1-2. Slow charging:

AC charging usually takes 5 to 8 hours, depending on the battery capacity and the power of the charger.

II. Electric car factors

2-1. Battery capacity: The larger the battery capacity, the longer it usually takes to charge.

2-2. Remaining power: When the remaining power of an electric car is low, it will take longer to charge. For example, when the power is less than 20%, it should be charged in time, and it may take longer to fully charge. If the remaining power is large, it can be fully charged in a shorter time.

2-3. Battery type and characteristics: Different types of batteries (such as lithium iron phosphate batteries, ternary lithium batteries, etc.) have different charging characteristics, which will also affect the charging time.

3. Charger factors

3-1. Charger power: The higher the power of the charger, the faster the charging speed is usually. For example, a 7kW AC charger takes 5 to 8 hours to fully charge, while a high-power DC charger can complete the charging in a shorter time.

3-2. Charger type: Although floor-standing and wall-mounted chargers are only installed in different locations and do not affect the charging time, there may be functional differences between public chargers and dedicated chargers, but this difference usually does not directly affect the charging time.

4. Other factors

4-1. Charging efficiency: There will be a certain amount of energy loss during the charging process, such as heat loss caused by resistance heating, which will affect the actual charging efficiency. Generally speaking, the charging efficiency is between 85% and 90%.

4-2. Charging environment: Ambient temperature, humidity and other conditions may also have a certain impact on the charging time. For example, in a low temperature environment, the performance of the battery may decline, thereby affecting the charging speed.

In summary, the time required to charge an electric car at a public charging station is a complex issue that requires consideration of the combined effects of multiple factors. Therefore, it is impossible to give a fixed charging time. In actual operation, it is recommended to reasonably arrange the charging time based on factors such as the actual situation of the electric car, the type and power of the charger, and the charging environment.
