Understanding Why Your Tesla Isn’t Charging at 48 Amps: Troubleshooting Guide

Today, we’re going to observe a normal charging session with an electric car and closely monitor the process. As we initiate the charge, we’ll pay attention to the performance of the wall connector and the fluctuations in amperage and voltage. Let’s dive into the details of our charging test:

As the charging begins, we observe the communication between the car and the wall connector. The initial amp and volt readings indicate a smooth start with no errors.

Throughout the session, we notice fluctuations in amperage and voltage, which is a common occurrence during car charging. Despite a momentary drop in amperage, the system quickly stabilizes and resumes the charging process.

At one point, we encounter an error and observe the behavior of the wall connector when the charge is stopped and restarted. We note the volt readings and the fluctuation in amperage as the system attempts to resume charging.

Throughout the test, we witness the amperage climbing, dropping, and stabilizing multiple times without a consistent pattern. Despite the intermittent fluctuations, the charging process continues without any major issues.

As the test concludes, we are left pondering the cause of the intermittent drops and fluctuations in amperage and voltage. The behavior of the wall connector during start and stop commands raises questions about the charging process and the system’s response to certain commands.

In conclusion, our observation provides valuable insights into the dynamics of electric car charging and highlights the need for further investigation into the charging process and system behavior.

Stay tuned for more testing and observations in the world of electric vehicles!

What is the normal charge process like?

The normal charge process involves the wall connector communicating with the car and starting to ramp up the charging process without any errors. It begins at 16 amps and 244 volts, slowly climbing up to 32, 34, and eventually reaching 48 amps with 12 kilowatts at 241 volts.

Are there any voltage fluctuations during the charging process?

There are minimal voltage fluctuations, with a tiny variation observed. At one point, the voltage dropped, but it picked back up and remained stable at 240 volts. However, it eventually dropped with an error message when the amperage decreased to 32 and 8 kilowatts.

What happens when the charging process stops?

When the charging process stops, there may be instances where the wall connector shows a voltage of two volts and then kicks back on, pulling in two to three amps. Despite attempts to stop and start the charging process, the issue persists without a clear cause.
