Tesla vehicles use a High Voltage System to power their electric motors.
In the most recent models, the lithium-ion battery supplies a nominal voltage of 400 volts (V) or more, and this voltage is converted by the inverter into three-phase alternating current with special characteristics that will later feed the electric motors.
This three-phase alternating current is sent to the electric motors, which convert electrical energy into motion. The electric motors in Tesla vehicles are known for their energy efficiency and their ability to provide quick and smooth acceleration.
The High Voltage System in Tesla vehicles also includes safety measures to ensure that their occupants are protected in the event of a collision or other emergency situation. For example, high voltage cables are insulated and protected by a waterproof and fire resistant metal casing.
Vehicle Security Systems are designed to detect any fault in the High Voltage System and automatically disconnect the battery in the event of a failure.
On the other hand, the entire High Voltage System is completely isolated from the bodywork and its isolation must be complete. Any high voltage leak, no matter how small, will generate an alert for loss of insulation and the vehicle will not be able to be driven.
The services available for High Voltage System are:
Evaluation and solution of problems related to insulation losses or high voltage leaks.
Evaluation of problems with alerts linked to the High Voltage System.
Verification of the High Voltage System.

Alerts indicating a problem with the High Voltage System:
If you have any of the following alerts on the screen, your Tesla is having a problem related to the High Voltage System.
To identify the problem, we must carry out an evaluation and prepare an EV-Intelligent Report.
These alerts start with BMS – HVP.
