Tesla Model X High-Voltage System Repair
ElectricZentrum specializes in the repair and maintenance of electric vehicles (BEV), offering dedicated services for the Tesla Model X. We service the high-voltage battery, inverter/drive unit, onboard charger (OBC), DC/DC converter, and thermal system (heat pump/Octovalve), ensuring original performance and safety.
Our technicians are certified in high-voltage (HV) systems and use diagnostic equipment and procedures fully compatible with Tesla specifications, ensuring safe, traceable, and high-quality repairs.
Technical Diagnosis and Specialized Intervention
The Tesla Model X integrates an HV battery, drive unit with inverter, OBC, DC/DC converter, and an advanced thermal system controlling the temperature of both the battery and the power electronics. We perform a complete HV diagnostic, including insulation tests, under-load measurements, and CAN communication analysis to precisely locate the root cause of faults.
Common symptoms include “Power reduced” warnings, AC/DC charging failures, insulation alerts, and power limitation. After diagnosis, we apply the most appropriate technical solution to ensure reliability and safety.
High-Voltage Battery Repair and Replacement
Over time, the HV battery may degrade, leading to reduced range or charging faults. At ElectricZentrum, we perform HV battery repair and reconditioning, including capacity testing, balancing, and controlled load evaluations.
We also provide new compatible cell packs tested under HV safety standards, restoring original performance, autonomy, and durability.
Drive Unit / Inverter, OBC and DC/DC
We carry out drive unit and inverter repairs (power loss, noise, error messages), OBC repairs (slow/intermittent AC charging), and DC/DC converter servicing (12V low voltage alerts). Each repair undergoes load testing and HV insulation verification.
- Extensive experience in Tesla electric system repairs;
- HV battery repair and drive unit/inverter repair with full warranty;
- Availability of new cell packs for Tesla Model X;

Common Tesla Model X Alerts/Faults
During diagnostics, the following messages/codes may appear, related to the HV and traction system:
| Message / Code | Description |
|---|---|
| Battery Problem / Service Required | Excessive voltage detected in an HV battery “brick”, which may trigger a safety shutdown. |
| Isolation resistance warning | Insulation resistance below the safe limit — possible current leakage or humidity in HV battery or cabling. |
| Charging Problem | Fault in the charging system (port, connector, OBC) or related high-voltage circuit. |
| Powertrain Problem – Restart When Safe | Fault in the electric traction system or power modules; requires restart or technical intervention. |
Service Reliability and Warranty
All interventions follow HV safety protocols and are performed by certified technicians. Our goal is to ensure every Tesla Model X retains its original performance, range, and reliability after repair.
ElectricZentrum offers HV battery repairs, inverter/drive unit repairs, OBC, DC/DC, and new cell packs for the Tesla Model X — delivering safe, efficient, and warranted technical solutions.
