1. Understanding OEM Scan Tools and Charging History Data

1.1 What Are OEM Scan Tools?

OEM (Original Equipment Manufacturer) scan tools are diagnostic devices specifically designed by vehicle manufacturers for their own vehicles. These tools provide in-depth access to vehicle systems, allowing technicians to diagnose and repair issues with precision. According to leading automotive diagnostic equipment manufacturers, OEM tools offer the most comprehensive diagnostic capabilities for their respective brands.

1.2 The Importance of Charging History Data

Charging history data, encompassing AC and DC charging sessions, provides valuable insights into a vehicle’s usage patterns, battery health, and charging behavior. This data can help diagnose charging-related issues, optimize charging schedules, and assess the overall performance of electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs).

1.3 Can OEM Tools Access Charging History Data?

Yes, OEM scan tools generally have the capability to access data related to the vehicle’s charging history, including AC/DC charging sessions. This access is typically more comprehensive compared to aftermarket scan tools.

2. How OEM Tools Access Charging History Data

2.1 Direct Access to Vehicle Control Units (VCUs)

OEM scan tools are designed to communicate directly with the vehicle’s control units (VCUs), including the Battery Management System (BMS) and other relevant modules. This direct communication allows technicians to retrieve detailed charging history data.

2.2 Proprietary Diagnostic Protocols

OEMs often use proprietary diagnostic protocols that are not fully accessible to aftermarket scan tools. These protocols enable OEM tools to access specific data parameters (PIDs) related to charging history.

2.3 Software and Firmware Updates

OEM scan tools receive regular software and firmware updates, ensuring compatibility with the latest vehicle models and access to new data parameters. These updates often include enhancements to charging history data retrieval and analysis.

3. Types of Charging History Data Accessible via OEM Tools

3.1 AC Charging Sessions

OEM tools can typically access data related to AC charging sessions, including:

• Charging Duration: The length of time the vehicle was connected to an AC charging station.
• Energy Delivered: The amount of energy (in kWh) delivered to the vehicle during the charging session.
• Charging Rate: The rate at which the vehicle was charged (e.g., kW).
• Start and End Times: The exact times the charging session started and ended.
• Charging Station Location (if available): The location of the charging station used.

3.2 DC Charging Sessions

For DC charging sessions, OEM tools can provide even more detailed data, such as:

• Charging Duration: The length of time the vehicle was connected to a DC fast charger.
• Energy Delivered: The amount of energy (in kWh) delivered to the vehicle during the fast charging session.
• Charging Rate (kW): The rate at which the vehicle was charged, often varying during the session.
• Start and End Times: The precise start and end times of the fast charging session.
• Charging Station Location: The location of the DC fast charger.
• Battery Temperature: The temperature of the battery pack during the charging session.
• Voltage and Current Levels: Detailed voltage and current readings throughout the charging process.

3.3 Overall Charging Statistics

In addition to individual charging sessions, OEM tools can often provide overall charging statistics, including:

• Total Energy Charged: The total amount of energy charged over the vehicle’s lifetime.
• Number of Charging Sessions: The total number of AC and DC charging sessions.
• Average Charging Rate: The average charging rate across all charging sessions.
• Time Spent Charging: The total time spent charging the vehicle.

4. Advantages of Using OEM Tools for Charging History Analysis

5.3 Lack of Vehicle-Specific Procedures

Aftermarket tools may lack vehicle-specific diagnostic procedures, potentially leading to inaccurate diagnoses and ineffective repairs.

6. Case Studies: OEM Tools in Action

6.1 Diagnosing Slow Charging Issues

A technician uses an OEM scan tool to diagnose a slow charging issue on an electric vehicle. By analyzing the charging history data, the technician identifies that the vehicle is consistently charging at a lower rate than expected. Further investigation reveals a faulty charging cable that is limiting the charging current.

6.2 Identifying Battery Degradation

An OEM scan tool is used to assess the battery health of a plug-in hybrid vehicle. The charging history data shows a gradual decrease in the amount of energy delivered during each charging session. This indicates battery degradation, which is confirmed by further battery testing.

6.3 Resolving Premature Charging Termination

A customer reports that their electric vehicle is terminating charging sessions prematurely. Using an OEM scan tool, a technician analyzes the charging history data and discovers that the battery temperature is exceeding the maximum allowable limit during charging. This triggers the charging system to terminate the session to protect the battery.

7. Essential Scan Tool Functions for Accessing Charging History

7.1 Reading Diagnostic Trouble Codes (DTCs)

OEM scan tools can read diagnostic trouble codes (DTCs) related to the charging system. These codes provide valuable clues about potential issues.
