Specialised Technical Service for Next-Generation Vehicles
At ElectricZentrum, we are a specialist workshop in the maintenance of electric and plug-in hybrid vehicles, equipped with cutting-edge technology and certified technicians.
Periodic maintenance of these vehicles is essential to ensure performance, safety and durability, since electrical and electronic systems require advanced technical knowledge and specific equipment.
With over 10 years of experience in the electric automotive sector, ElectricZentrum offers tailored maintenance plans, adapted to the vehicle type, usage and each manufacturer’s recommendations.
Every service is performed with full traceability and comprehensive electronic diagnostics, ensuring your car maintains maximum energy and operational efficiency.
High-Voltage Battery Maintenance
The high-voltage battery is the heart of electric and hybrid vehicles.
At ElectricZentrum we carry out detailed technical inspections to assess:
- State of Health (SoH) and actual storage capacity;
- Individual cell and module voltage;
- Battery temperature and thermal balance;
- Battery Management System (BMS) efficiency;
- Insulation checks and detection of electrical leakage.
This process allows early anomaly detection, prevents major failures and ensures maximum range and battery longevity.
We use certified diagnostic tools compatible with all major brands — Tesla, BMW, Hyundai, Kia, Renault, Nissan, Toyota, among others.
12V Auxiliary Battery
The 12V battery powers onboard electronic systems, lighting and safety features.
Even in electric vehicles, this component is crucial for initialising the main systems and communicating with electronic modules.
During maintenance, we perform:
- Charge and discharge testing;
- Verification of voltage at rest and under load;
- Preventive replacement when necessary.
Keeping the 12V battery in good condition prevents unexpected failures and communication errors between modules.
Tyres, Braking and Suspension Checks
Electric and hybrid vehicles have specific characteristics — greater weight due to the batteries and instant torque — which require rigorous tyre and suspension maintenance.
At ElectricZentrum, we assess:
- Tyre pressure, wear and alignment;
- Dynamic balance of the suspension and shock absorbers;
- Regenerative braking system, which converts kinetic energy into electrical energy during deceleration.
Diagnosing the regenerative braking system is essential to ensure optimised range and safety in all driving conditions.
Charging System and Electrical Components
During maintenance we perform a full check of the charging system, including:
- Charging port (socket and connectors);
- Cables and charging communication system (EVSE);
- Onboard charger efficiency and compatibility with external chargers;
- Electrical safety and insulation tests.
A well-calibrated charging system ensures fast, safe and efficient charging, preventing high-voltage circuit failures and extending battery life.
Software Updates and Electronic Diagnostics
Modern electric and hybrid vehicles rely heavily on software and intelligent control systems.
At ElectricZentrum, we carry out:
- Manufacturer-recommended software updates;
- Reprogramming and calibration of electronic modules;
- Reading and clearing of Diagnostic Trouble Codes (DTCs);
- Operational log analysis.
These updates improve performance, energy efficiency and vehicle safety, keeping it aligned with the latest manufacturer specifications.
Compliance with Manufacturer Recommendations
Each maintenance task is performed according to the manufacturer’s official guidelines, respecting intervals, procedures and parts/fluids specifications.
This ensures:
- Preservation of the factory warranty;
- Reduction of premature failures;
- Longer service life and higher resale value of the vehicle.
At ElectricZentrum, we ensure your electric or hybrid vehicle remains safe, efficient and up to date, using only quality components and certified methods.
