Type 2 charging, also known as AC or alternating current charging, is a commonly used method for charging electric vehicles (EVs). This article aims to explain the speed at which Type 2 charging can charge an EV and provide a better understanding of its technical aspects.
The basics of Type 2 charging
Type 2 charging relies on a dedicated charging station or point that delivers alternating current to the EV. The charging station is connected to the EV via a Type 2 connector, which supports single-phase or three-phase charging. It is crucial to note that the charging speed depends on the maximum power the EV and the charging station can handle.
Charging speeds and variations
The charging speed of Type 2 charging varies depending on the power supply available, the EV's onboard charger's capacity, and the charging station's output power. Most charging stations offer different output power options, typically ranging from 3.7 kW to 22 kW for single-phase charging and up to 43 kW for three-phase charging. The higher the power rating, the faster the charging speed.
For example, if the EV's onboard charger has a maximum capacity of 7 kW and the charging station provides 11 kW of power, the charging process will be limited to 7 kW. However, if the charging station offers 22 kW of power, it will still be limited to 7 kW due to the EV's onboard charger's capacity. To take full advantage of faster charging speeds, you need an EV with a powerful onboard charger and a charging station that can support it.
Factors affecting charging time
Several factors can influence the overall charging time of Type 2 charging. Firstly, the EV's battery capacity plays a significant role. The larger the battery capacity, the longer it will take to charge fully. Secondly, the current state of charge (SoC) of the battery impacts charging time. Charging slows down as the battery reaches higher levels of SoC to prevent overcharging.
Additionally, environmental conditions can affect charging speed. Extremely high or low temperatures may decrease the charging rate to protect the battery's lifespan. Furthermore, some vehicles have built-in features that control the charging rate to optimize battery health and performance.
In conclusion, Type 2 charging offers varying charging speeds depending on factors like power supply, onboard charger capacity, and output power of the charging station. To maximize charging speed, it is crucial to consider these factors when purchasing an EV and selecting a compatible charging station.
