We adhere to all recommended Tesla diagnostic protocols to provide an accurate assessment you can trust. This includes running comprehensive software diagnostics, performing insulation and impedance testing, coolant system analysis, and thorough visual inspections.
Understanding Tesla High Voltage Battery Issues
The high voltage battery in a Tesla is a rechargeable lithium-ion battery pack made up of thousands of individual cylindrical cells working in series. Issues can develop due to:
- Manufacturing Defects
- Physical Damage
- Exposure to Extreme Temperatures
- High Resistance Connections
- Coolant System Failures
- Age and Normal Wear
Allowing any of these issues to persist can potentially lead to decreased range and performance, total battery failure, or even safety risks in worst case scenarios. Prompt professional diagnosis and repair is essential.
Advanced Battery Diagnostic Procedures
Our diagnostic process is comprehensive and follows all recommended best practices, including:
- Running the Latest Approved Tesla Battery Testing Software
- Performing Battery Pack Insulation and Ground Fault Testing
- Measuring Cell/Module Impedance and Voltage
- Analyzing Battery Coolant Flow and Chemistry
- Inspecting for Physical Damage and Corrosion
- Testing the Battery Management System
This multi-point inspection allows us to collect detailed data points and accurately identify the root cause, rather than just treating symptoms. Ceramic Coating
