When testing for faults on zappi, it is critical to follow a specific procedure to ensure the unit operates correctly and to protect the electric vehicle (EV) in real-world scenarios. This guidance applies to tests that intentionally induce a fault and stop charging, such as Residual Current Device (RCD) testing or DC Leakage testing. Such tests are essential for validating the safety mechanisms of zappi, but they temporarily interrupt charging as part of the safety protocol.
To proceed with each stage of testing without issue, please follow the steps below after performing each test that stops charging in full:
- Disconnect the Tester from zappi
After completing a test (such as an RCD or DC Leakage test) that halts charging, disconnect the testing equipment from zappi. This is an important first step to allow the system to reset and prepare for the next test. - Reboot zappi
Rebooting zappi after each test that stops charging is crucial. This reset clears the error state caused by the fault-inducing test and allows zappi to resume normal operation, readying it for further testing or general use. To reboot zappi, simply power the unit off and on again, or follow the device-specific reboot instructions. - Continue with the Next Test
Once zappi has rebooted, you may proceed with the next test. By resetting the device after each fault-inducing test, you ensure that each test begins from a neutral state, improving test accuracy and ensuring that the EV is protected.
Why This Procedure is Necessary
The requirement to reboot zappi after each fault-inducing test is a safety precaution designed to protect the EV in real-world situations. If a fault such as an RCD trip or DC leakage event were to occur outside of a controlled testing environment, zappi would automatically stop charging to protect both the vehicle and the electrical system. Rebooting after these tests confirms that zappi’s safety protocols are functioning correctly and that any transient error is reset, maintaining safe charging conditions.
By following this protocol, you ensure both accurate testing and the ongoing safety of zappi and the connected EV.
