Data streams provide real-time information about various parameters within the vehicle’s systems. For EVs and hybrids, these parameters include battery health, motor performance, inverter operation, and regenerative braking efficiency. Analyzing these data streams helps technicians identify anomalies, predict failures, and optimize vehicle performance. As noted in a study by the National Renewable Energy Laboratory (NREL), real-time data analysis is critical for ensuring the reliability and safety of EV and hybrid powertrains.

1.3 Key Differences in Diagnostic Approaches for EVs/Hybrids Compared to ICE Vehicles

Traditional internal combustion engine (ICE) vehicles rely on data streams related to engine performance, fuel injection, and exhaust emissions. EVs and hybrids, however, require a focus on electrical systems, battery management, and energy recovery. This shift necessitates a different set of data streams for effective diagnostics. The University of California, Davis, in a research paper, highlighted that the diagnostic tools for EVs/hybrids must be capable of handling the unique data generated by these systems.

2. Essential Data Streams for Electric Vehicle (EV) Diagnostics

Electric vehicle diagnostics require access to specific data streams that provide insights into the performance and health of the vehicle’s electrical components. These data streams are crucial for identifying issues related to the battery, motor, inverter, and other critical systems.

2.1 Battery Management System (BMS) Data

The Battery Management System (BMS) is responsible for monitoring and controlling the battery pack. Key data streams from the BMS include:

• Cell Voltages: Individual cell voltages indicate the health and balance of the battery pack. Significant voltage variations among cells can indicate a faulty cell or module.
• Battery Temperature: Monitoring the temperature of the battery pack is crucial for preventing overheating and ensuring optimal performance. High temperatures can degrade battery life and performance.
• State of Charge (SOC): SOC indicates the remaining energy in the battery pack as a percentage. Accurate SOC data is essential for range estimation and preventing over-discharge.
• State of Health (SOH): SOH provides an indication of the battery’s overall condition compared to its original state. A declining SOH indicates degradation and reduced capacity.
• Charging/Discharging Current: Monitoring the current flow during charging and discharging helps identify issues with the charging system or excessive current draw.

According to a study by Argonne National Laboratory, accurate BMS data is essential for predicting battery lifespan and ensuring safe operation.

2.2 Motor and Inverter Data

The electric motor and inverter are critical components of the EV powertrain. Relevant data streams include:

• Motor Speed: Indicates the rotational speed of the motor, which is directly related to vehicle speed.
• Motor Torque: Measures the amount of rotational force produced by the motor.
• Motor Temperature: Monitoring motor temperature prevents overheating and potential damage.
• Inverter Voltage and Current: These parameters indicate the performance and efficiency of the inverter, which converts DC power from the battery to AC power for the motor.
• DC Link Voltage: Measures the voltage between the battery and the inverter, providing insights into the power flow within the system.

Research from the University of Michigan Transportation Research Institute (UMTRI) emphasizes the importance of monitoring motor and inverter data for diagnosing performance issues in EVs.

• Motor and Inverter Data: Motor speed, motor torque, motor temperature, inverter voltage and current, and DC link voltage.
• Regenerative Braking Data: Measures the amount of energy recovered during braking.

3.3 Unique Hybrid Data Streams

In addition to the above, hybrid vehicles have unique data streams related to the interaction between the engine and electric motor:

• Power Split Data: Indicates how power is being distributed between the engine and electric motor.
• Mode of Operation: Indicates the current operating mode of the hybrid system (e.g., electric mode, hybrid mode, engine mode).
• Transition Data: Monitors the transitions between different operating modes, helping identify issues with the hybrid control system.

A study by the Society of Automotive Engineers (SAE) highlights the complexity of hybrid vehicle diagnostics due to the interaction between the engine and electric powertrain.

3.4 Integration of Data Streams
