EURO AINDEX MIT200 Series Electric Vehicle
Specifications
- Product: Electric Vehicle Charging Equipment
- Manufacturer: Megger
- Application Note: 82
Product Information
- Electric Vehicle Supply Equipment (EVSE) is essential for charging electric vehicles. EVSE can vary from basic domestic charging points to advanced systems for commercial/industrial applications.
- Megger offers a range of products suitable for testing EVSE, including continuity and insulation testers, loop testers, RCD testers, earth testers, and portable appliance testers.
Product Usage Instructions
Supply Tests
- Ensure that the supply to the charger complies with BS 7671.
- Perform standard installation tests like continuity, insulation, RCD, and earth loop impedance tests.
- Check for the presence of an RCD in the outlet and test its functionality.
Earth Resistance Tests
- Most installations require an additional connection to the ground at the charging point.
- Use an earth spike or electrode to establish this connection for protection under fault conditions.
Portable Appliance Tests
- Some charging systems come with detachable cables for connecting the charging point to the vehicle.
- Periodically test the integrity of the earth path provided by the cable and ensure the insulation quality is maintained. These tests can be part of a portable appliance test.
FAQ
Q: What are some Megger products suitable for testing EVSE?
A: Megger offers various products for testing EVSE, including the MIT200, MIT300, and MIT400 series for continuity and insulation testing, LTW325, LTW335, and LTW425 for loop testing, RCDT320 and RCDT330 for RCD testing, DET3 and DET4 for earth testing, and PAT300 and PAT400 series for PAT testing.
TESTING ELECTRIC VEHICLE SUPPLY EQUIPMENT
Electric vehicle supply equipment (EVSE)
Electric vehicles are still in their infancy but may one day appear on every driveway in the country, along with their EVSE.
- In domestic households, the charging point will most likely appear simply as a dedicated BS 1363 socket outlet located on a driveway, provided all parts of the charging circuit are integrated into the vehicle itself.
- For vehicles that do not include the full charging circuit, a charging device, such as the one shown, may be wired into the supply.
- For commercial/industrial applications, in addition to the method for domestic uses, there may be more advanced charging systems in place. These may include rapid charging systems and high-current chargers for larger vehicles.
Supply Tests
- The supply to the charger must comply with BS 7671. This means that all standard installation tests, such as; continuity, insulation, RCD, and earth loop impedance, must be taken as normal.
- Some EVSE may have an RCD incorporated into the outlet, this should also be checked to ensure it trips in a suitable amount of time.
- For larger installations, the charger may be supplied by 400 V. Our applications note on testing three-phase systems explains how to test 400 V supplies.
Earth Resistance Tests
- Most installations require an additional connection to the ground at the charging point so that there is still a form of protection under fault conditions. This connection would be made by an earth spike/electrode driven into the ground.
- Simply driving an earth spike into the ground and connecting it to the system will not guarantee a good quality earth connection. A good earth connection would require a low resistance loop reading, typically below 200 Ω.
- To ensure a good earth connection before making the circuit live a test of the earth resistivity should be performed.
- This test is taken between the earth electrode which has been installed and two test spikes driven into the ground for the duration of the test. As shown in the diagram below.
Portable Appliance Tests
- Some of the charging systems include a detachable cable for connection between the charging point and the vehicle. This cable provides an earth path to the vehicle, the integrity of which should be tested periodically, along with the quality of the insulation.
- These tests can be performed as part of a portable appliance test.
