What is AC Charging of GB/T 20234?

AC Charging under the GB/T 20234 standard refers to the specifications set for alternating current (AC) charging of electric vehicles (EVs) in China. This standard defines how AC power is delivered to the vehicle and provides guidelines for the charging interface and communication protocols between the vehicle and the charging equipment. The key aspects of **GB/T 20234 AC charging** include:

1. Connector Types
   - The AC charging standard (GB/T 20234.2) outlines a specific connector design used for AC charging in China.
   - Single-phase or three-phase connectors are used, depending on the power rating.
   - The connector has distinct pins for power transfer, grounding, and communication between the vehicle and the charging station.

2. Power Ratings
   - AC charging generally provides slower charging compared to DC charging, as it delivers lower power levels.
   - The standard supports a range of power levels, typically up to 7.4 kW for single-phase and 63 kW for three-phase AC charging.
   - This level of charging is mainly suitable for overnight charging at homes, offices, or public parking stations.

3. Communication Protocol
   - GB/T 20234.2 also defines a communication protocol to ensure compatibility between the vehicle and the charging station.
   - This protocol governs charging status, voltage, current levels, and safety checks.
   - Pulse-width modulation (PWM) is used for signaling and controlling the charging process.

4. Charging Process
   - During AC charging, the electricity supplied from the grid is converted by the EV’s onboard charger into DC power to charge the vehicle’s battery.
   - This contrasts with DC charging**, where the conversion happens outside the vehicle at the charging station itself.

5. Safety Features
   - The standard includes **safety provisions** such as grounding and insulation checks to prevent electric shock.
   - It also ensures the vehicle and charging equipment are properly connected before power is supplied.

6. Use Cases
   - AC charging based on GB/T 20234 is typically used for slower charging scenarios, such as home charging or public charging stations where speed is less critical.
   - It is suitable for longer charging sessions that may last several hours.

In summary, AC charging under GB/T 20234 is designed for everyday use in residential or low-power public settings, offering a reliable and safe method for charging EVs in China.
