EV Charging Station Overview
EV Charging Station refers to a charging device that provides energy supplement for electric vehicles. Its function is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential areas In the parking lot or charging station, various types of electric vehicles can be charged according to different voltage levels. The battery of an EV can only receive direct current (DC) and voltage, while the grid/household outlet provides alternating current (AC), so the home charging station converts the AC to DC and then charges the EV battery.
AC Charging VS DC Charging
AC charging : power supply (AC) → AC charger → car charger (AC to DC) → battery
DC charging : power supply (AC) → DC charger (AC to DC) → battery
The AC Charging Process
During AC charging, the EV’s onboard charger converts AC power to DC power and controls the charging process. AC charging is typically slower than DC charging, making it suitable for overnight charging or longer parking durations.
AC charging is widely available and compatible with most EVs, making it a convenient option for daily use. However, its charging speed is relatively slower compared to DC charging.
The DC Charging Process
Direct Current (DC) charging, on the other hand, offers higher charging speeds and is often used for rapid charging scenarios.
DC charging stations directly provide DC power to the EV’s battery, bypassing the need for an onboard charger. This results in faster charging times, making DC charging ideal for drivers on the go.

EV Charger Connector Type
Type 1 (SAE J1772): This connector is widely used in North America and Japan. It has a J-shaped design and is intended for single-phase AC charging.
Type 2 (IEC 62196-2, also known as Mennekes): This connector is commonly used in Europe and supports both single-phase and three-phase AC charging, as well as DC charging.
CHAdeMO: This connector type is primarily used for DC fast charging and was developed in Japan. It’s commonly found on electric vehicles in Japan and some other regions.
Combo Connector (CCS, Combined Charging System): This connector integrates both AC and DC charging into a single design. It combines the Type 2 connector with additional DC pins for fast charging. CCS Combo 1 is primarily used in North America, while CCS Combo 2 is used in Europe and other regions.
Tesla Connector (Tesla Supercharger): Tesla has its own proprietary connector for their Supercharger network. However, they also provide adapters for other connector types.
GB/T Connector (GB/T 20234.2-2011): This connector is used in China for both AC and DC charging and has different variations for different power levels.
IEC 60309 (also known as IEC 60309-2 or “industrial plug”): While not specific to electric vehicles, this standard is sometimes used for high-power charging in commercial and industrial settings.
AC Charger Power Calculation Method
Calculating the power of an AC electric vehicle (EV) charger involves a straightforward formula based on the voltage and current ratings of the charger. The formula to calculate power is:
Power (Watts) = Voltage (Volts) × Current (Amps)
Here’s how you can use this formula to calculate the power of an AC EV charging station:
Determine the Voltage Rating: Check the specifications of the EV charging station to find the voltage rating. In most cases, AC EV chargers for homes or public charging stations have a voltage rating of either 120V or 240V.
Determine the Current Rating: Find the current rating of the car charger. It is usually mentioned in terms of amps (A). Common current ratings for residential chargers are 16A, 32A, 40A, etc.
Plug in the Values: Plug the voltage and current ratings into the formula:
Power (Watts) = Voltage (Volts) × Current (Amps)
For example, if you have a charger with a voltage rating of 240V and a current rating of 32A:
Power = 240V × 32A = 7680 Watts (or 7.68 kW)
Convert to Kilowatts (Optional): Power is often expressed in kilowatts (kW) for simplicity, as EV charging rates are commonly discussed in kW. To convert watts to kilowatts, divide the power value in watts by 1000. In the example above, 7680 watts is equivalent to 7.68 kW.
Remember that this calculation gives you the maximum potential power output of the charger. The actual power delivered to your EV might vary due to factors like the efficiency of the EV charging station and the charging cable.ing
The Main Types of EV Chargers in US:
The easiest method of charging an electric car includes connecting it directly into a regular 120-volt household socket. This option charges at the slowest rate, often delivering 2 to 5 miles of range each hour. When overnight charging is adequate, it is frequently employed.
A dedicated EV charging station must be installed in order to use the more advanced Level 2 charging option. Compared to Level 1, these stations offer faster charging rates and operate on a 240-volt circuit. Both public charging stations and private settings frequently employ level 2 charging. Depending on the car and the charger’s power output, the rate of charging can be anywhere from 10 to 60 miles per hour.
The quickest charging technique is DC fast charging, which is frequently utilized for long-distance travel or when fast charging is required. Specialized equipment is needed for this sort of charging, which is often offered at public charging stations. With a DC fast charger, you can get a lot of range quickly. Typically, you can get 60 to 100 miles of range within 20 to 30 minutes of charging.
The Main Types of EV Chargers in EUROPE:
Mode 1 Charging:
The simplest type of charging, known as mode 1 charging, involves connecting the EV to a regular household outlet with the charging cable that was included with the car. It does not require any additional control mechanisms or charging apparatus. However, due to its restricted power capacity, this method may not be the best or safest choice for routine EV charging.
Mode 2 Charging:
Using a charging cable with an integrated control and safety device is how mode 2 charging is accomplished. The car is connected to this control box, also known as a “charging station” or “control unit,” which is located between the vehicle and a typical household outlet. Compared to Mode 1 chargers, Mode 2 chargers offer some protection and control over the charging process, improving safety.
Mode 3 Charging:
Mode 3 charging is the most common method for public and home charging stations. It involves a dedicated EV charging station (also known as an Electric Vehicle Supply Equipment or EVSE) that is permanently installed and provides higher power levels. Mode 3 chargers are connected to the electrical grid and the vehicle using specific connectors, and they include safety features and communication protocols to ensure safe and efficient charging.
Mode 4 Charging:
Mode 4 charging is typically used for fast charging at public EV charging stations. This mode involves a DC (direct current) charger that provides very high power levels and requires specialized infrastructure. Mode 4 chargers are not as common for home use due to their complexity and cost.
Single-Phase Charging:
Single-phase EV charging stations are designed to work with single-phase AC power. They are commonly used for residential charging, such as home lighting, appliances, TVs, washing machines, etc. Single-phase electricity has three wires, live wire, neutral wire and ground wire. The equipment takes power through the live wire and the neutral wire, and the voltage between the two wires is 230 volts. Single-phase charging is suitable for lower power charging needs, such as overnight charging at home.
Single-Phase Charging:
Three-phase EV charging stations are designed to work with three-phase AC power. Three-phase power is used for some high-power residential power supply, mainly for industrial high-power manufacturing equipment. Three-phase electricity generally has 5 wires, three live wires, one neutral wire, and one ground wire. The equipment takes power through three live wires, and the voltage between each two live wires is 400 volts. Three-phase power enables more efficient and faster charging, making it suitable for charging larger electric vehicles or when faster turnaround times are required. These chargers are typically used in commercial and public charging stations, and where higher charging speeds are required.
