EV Battery Health Diagnostics System Market Size - By Battery, By Diagnostics, By Service Model, By Diagnostic Method, By End Use, Growth Forecast, 2025 - 2034

EV Battery Health Diagnostics System Market

The global EV battery health diagnostics system market size was valued at USD 2.2 billion in 2024 and is estimated to register a CAGR of 11.6% between 2025 and 2034.
 

The market is poised for healthy growth, driven by the rapid growth of electric vehicles (EVs) worldwide, along with an increasing concern for battery safety, performance, and lifespan. As EVs become more preferred in both the personal and commercial transport sectors, the need for reliability and longevity of batteries has become more urgent, making battery diagnostics systems imperative for automotive manufacturers, fleets, and end users.
 

The surge of electric vehicles (EVs) due to government incentives, emissions standards compliance, and the lower price of lithium-ion batteries is creating demand for EV battery health diagnostics systems. As batteries are typically costly and are a necessary component of an EV, it is essential that the health of the battery be diagnosed in real-time. This means assessing the health status, failures, and performance of the battery as a whole.
 

For OEMs and fleet operators, adopting AI and IoT-enable diagnostics systems helps lower maintenance costs, allowing them to manage warranty claims more easily, and gives consumers confidence in using the vehicles. This makes EV battery health diagnostics system an important component of EV ownership and operations.
 

For instance, in June 2025, Motive, the AI-powered fleet platform, acquired InceptEV to help add integrated battery intelligence with real-time diagnostics through machine learning in their operations suite. InceptEV's algorithms helps in maximizing EV range forecasting, route planning, and total cost of ownership.
 

Technological advancements in diagnostics is another significant growth driver for the EV battery health diagnostics systems market. Currently, many systems are based on AI, ML, IoT sensors, and cloud computing to provide operational and predictive battery health information in real time. These technologies enable early detection of battery failures and offer more efficient charging and battery life.
 

Digital twins allow the operators to integrate simulated behavior of battery usage which can help with proactive maintenance, and over-the-air (OTA) updates enhance diagnostics as well as upgrade systems remotely. All of these emerging technologies thus helps lower costs, reduce downtime, and increase reliability of the EV battery to consumers and fleet operators alike.
 

EV Battery Health Diagnostics System Market Trends

• As costs for raw materials continue to rise and sustainability continues to be a major focus, secondhand use cases for EV batteries are becoming a key trend. Diagnostics systems are crucial in deciding whether a battery can be reused, resold, or recycled, or remediated for continued use.
   
• For instance, in April 2025, Poen (South Korea) developed methods for evaluating batteries based on a series of advanced battery testing and grading techniques to refurbish batteries with up to 80% usable capacity that are then used for stationary energy storage, microgrid applications, or sold as inexpensive products in secondary EV markets. This trend supports the circular economy objectives while also ensuring regulatory initiatives are followed related to battery waste and lifecycle management initiatives.
   
• Cloud-supported diagnostics solutions helps in activities such as remote monitoring, remote data storage, and predictive analytics to electric vehicle (EV) fleets that are distributed across geographic territories. This allows original equipment manufacturers (OEMs) or fleet managers or consumers to access the health status of vehicle fleets with real-time information to process any alerts through applications or dashboards. Over-the-air (OTA) diagnostics allow the manufacturers to implement updating or adding new diagnostic algorithms without the need of physical visits in service facilities.
   
• For instance, in August 2022, Sibros, a connected-vehicle technology firm partnered with Google Cloud to ensure in-use real-time diagnostics on-demand scalable capabilities for EV manufacturers as clients such as Sono Motors, Volta Trucks, and Lightyear, along with OEMs with new go-to-market fleet strategies for EV vehicles. This partnership emphasizes fleet health management and remote vehicle service with analysis and AI looking at cloud analytics, to provide smart data insights for service and analysis.
   
• AI and digital twins are changing battery diagnostics techniques. AI algorithms detect and flag early signs of battery deterioration or anomalies by analyzing vast amounts of current and historical battery data. Thus, it helps in predicting future performance for different uses to help OEMs and fleet operators make the necessary data-based decisions.
   
• In May 2025, N-IX, a software engineering company, offered an automated battery diagnostics solution leveraging robotics, digital twin and AI. N-IX's Digital Shadow digitally replicates the key parameters of the physical battery, including temperature and voltage, in real-time, but is primarily for assembly diagnostics, quality assurance and fault detection.
