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
