Testing a wallbox charger to ensure it meets the IEC 61851 standard involves a series of procedures to assess its electrical and functional performance. IEC 61851 is an international standard that defines the requirements for electric vehicle conductive charging systems. Below are some key steps and considerations for testing a wallbox charger against the IEC 61851 standard:

1. Understand IEC 61851 Standard:

• Familiarize yourself with the specific requirements outlined in the IEC 61851 standard. This standard covers various aspects, including safety, communication protocols, electrical performance, and interoperability.

2. Safety Testing:

• Verify that the wallbox charger complies with safety requirements. This includes testing for electrical safety, protection against electric shock, and insulation resistance.

3. Communication Protocol Testing:

• IEC 61851 defines communication protocols between the electric vehicle and the charging station. Ensure that the wallbox supports the required communication standards, such as Mode 3, and that it can effectively communicate with electric vehicles during the charging process.

4. Electrical Performance Testing:

• Check the electrical performance of the wallbox charger, including voltage, current, and power measurements. Ensure that the charger operates within the specified limits and that it provides the required power output.

5. Interoperability Testing:

• Verify that the wallbox charger can successfully charge different models of electric vehicles. Interoperability testing ensures that the charger can work seamlessly with various electric vehicles, regardless of the manufacturer.

6. Environmental Testing:

• Perform environmental tests to assess the charger's performance under different conditions, such as temperature variations and humidity levels. Ensure that the wallbox can operate reliably in the intended environmental conditions.

7. Durability Testing:

• Assess the durability of the wallbox charger by subjecting it to mechanical stress, vibration, and other factors. This ensures that the charger can withstand the rigors of daily
