Porsche Powers Up with AI: High-Voltage Performance Through Intelligent Data Analysis

Porsche is revolutionizing vehicle development by integrating artificial intelligence (AI) for advanced data analysis, particularly in high-voltage battery systems. This innovative approach allows for the processing of vast amounts of sensor data, ensuring optimal performance and extended lifespan for electric vehicles like the new Macan.

AI's Role in Battery Development

AI has become an indispensable tool for Porsche, especially when dealing with the intricate complexities of high-voltage batteries. The sheer volume of data generated by modern sensors necessitates AI and machine learning to extract meaningful insights. This enables engineers to understand component behavior and interactions, leading to more reliable and efficient systems.

Key applications of AI in battery development include:

• Detecting Implausible Behavior: Algorithms analyze the charge balance (balancing) of individual cells and the entire battery during the development phase. Deviations from expected values allow for rapid identification of underlying causes.

• Improving Data Quality: AI enhances the quality of development data, making insights from future customer vehicles even more reliable.

• Identifying Ageing Influences: Beyond known factors, AI-driven analysis, combined with physicochemical models, helps predict and analyze battery aging in customer fleets. This understanding informs optimization of operating strategies for range, charging time, performance, weight, and durability.

Explainable AI for Informed Decisions

Porsche emphasizes the use of "explainable AI" methods to ensure that the results of AI analyses are understandable and provide a reliable basis for decision-making. AI serves as a tool that, when combined with the expertise of Porsche's development engineers, allows for a precise classification of complex situations.

Preventive Anomaly Detection

A groundbreaking application of AI is preventive anomaly detection, first implemented in the high-voltage battery of the Porsche Macan. This system assesses the technical cause and relevance of any detected anomalies in the data, ensuring long-term performance and informing future product development.

How it works:

1. Intelligent Algorithms: Detectors use algorithms to identify changes in battery behavior from online data.

2. Cloud Analysis: Detected anomalies are analyzed, deciphered, and evaluated in the cloud.

3. Proactive Driver Notification: If a relevant anomaly occurs, Porsche proactively informs the driver, often via the MyPorsche app, with specific instructions.

This method can individually evaluate the data of each battery cell, making it a central element of future quality assurance, aiming to ensure vehicle reliability and performance while predicting potential limitations.
