Hybrid and Electric Vehicle Diagnostics
Specialists in Next-Generation Automotive Technology
At ElectricZentrum, we specialise in advanced diagnostics for hybrid and electric vehicles—an essential area for the maintenance, repair, and technical assessment of modern vehicles.
Using state-of-the-art automotive diagnostic equipment, we precisely analyse all electrical, electronic, and high-voltage systems, ensuring safe, efficient, and reliable operation.
Electric and hybrid vehicles employ complex technologies—such as high-capacity batteries, electric motors, inverters, and regenerative braking systems—that require specialised technical knowledge and specific diagnostic procedures.
Our certified technical team is prepared to carry out comprehensive assessments, identifying faults, component degradation, and performance anomalies with total rigour.
1. Advanced Diagnostics and Data Analysis
The diagnostic process for electric and hybrid vehicles begins with the collection and interpretation of technical data obtained through high-precision equipment. This analysis covers:
- Monitoring the battery cell voltage and resistance;
- Checking for electrical insulation faults and high-voltage leakage;
- Analysing communication between electronic control units (ECUs);
- Evaluating charging-system performance;
- Reading error codes and events stored in the system.
With this approach, ElectricZentrum technicians detect anomalies in real time, avoid unnecessary repairs, and reduce maintenance costs. This precise automotive technical diagnosis is essential to ensure safety and reliability in modern electric and hybrid vehicles.
2. Detailed Battery System Check
The high-voltage battery is the central component of any electric or hybrid vehicle. Our certified battery diagnostics include:
- Verifying individual cell and module voltage;
- Assessing charge and discharge capacity (SoH – State of Health);
- Monitoring battery temperature and thermal balance;
- Analysing the Battery Management System (BMS);
- Detecting insulation faults or cell degradation.
A battery with reduced performance can cause range loss, intermittent failures, and electrical risks. With ElectricZentrum’s specialised analysis, early anomalies can be detected and the proper intervention defined, extending system life and ensuring maximum energy performance.
3. Inspection of Electric Motors and Electronic Components
Automotive electric motors are highly complex components that require specialised diagnostics to ensure correct operation. During inspection we perform:
- Assessment of winding and bearing condition;
- Checks for signs of overheating or premature wear;
- Measurement of energy efficiency and current consumption;
- Diagnostics of inverters, converters, and power controllers, which regulate energy transfer between the motor and the battery.
Diagnosing inverters and controllers is especially important, as any failure in these components can compromise acceleration, regenerative charging, and overall vehicle safety. We use certified test equipment and follow manufacturer protocols and international standards.
4. Evaluation of Regenerative Braking Systems
Regenerative braking systems convert kinetic energy into electricity to recharge the high-voltage battery. During diagnostics, we verify:
- Efficiency of the energy-recovery process;
- Operation of speed sensors and braking control modules;
- Integration between hydraulic and regenerative braking systems;
- Vehicle behaviour under deceleration and light braking.
Inefficient regeneration reduces range and increases wear on mechanical brakes. ElectricZentrum’s detailed analysis ensures the ideal balance between performance, safety, and energy economy.
5. Road Test and Dynamic Assessment
After the full technical diagnosis, we perform controlled road tests to evaluate real-world vehicle behaviour. The following parameters, among others, are monitored:
- Electric-motor response during acceleration and deceleration;
- Transitions between electric, hybrid, and combustion modes (in plug-in hybrids);
- Energy-recovery efficiency during braking and deceleration;
- Stability of the electrical system under real load.
These tests complement the diagnostics and allow the identification of faults not detectable in a static environment, ensuring optimised performance and ideal safety conditions.
