CloseXPENG: LEADING MOBILITY INNOVATION AS THE FIRST OEM TO IMPLEMENT EIS BATTERY INTELLIGENCE
June 15, 2026
KEY TAKEAWAYS
|
The EV industry is at a crossroads. Manufacturers and consumers demand faster charging, but it comes at a steep price: battery degradation. This places greater emphasis on a battery management system (BMS), and, unfortunately, a traditional BMS only monitors surface-level signals such as V, I and T, leaving automakers reactive rather than proactive in addressing potential failures.
To address this challenge, XPENG Inc. partnered with Analog Devices, Inc. (ADI) to embed its pioneering EIS technology directly into XPENG’s vehicle architecture. This enables real-time insight into battery chemistry, allowing early detection of degradation and effectively turning the BMS into a predictive diagnostic engine that extends battery life and supports safer mobility.
AT A GLANCE
COMPANY
XPENG Inc. is a leading Chinese smart EV manufacturer that produces intelligent EVs featuring advanced autonomous driving capabilities, smart cockpit systems, and cutting-edge battery management technologies.
GOAL
Transform battery management from reactive to predictive, enabling faster, safer charging while extending battery life.
CHALLENGE
Balancing high-voltage, fast-charging performance with battery longevity and safety, while managing thermal stability and cost pressures across diverse mobility platforms.
ADI SOLUTIONS
ADI’s leading EIS technology integration for real-time battery health monitoring portfolio of automotive technologies, including Core BMS: ADBMS6842, ADBMS2970, ADBMS6822.
What Is EIS, and What Makes ADI’s EIS Different?
Electrochemical impedance spectroscopy (EIS) is a safe, non-destructive technique that measures a battery's internal resistance across multiple frequencies to predict degradation, thermal instability, and potential failures before they appear. ADI pioneered the technology and consolidated the full measurement chain on a single chip, uniquely pairing precision hardware with advanced algorithms that deliver actionable insights. This enables safer fast charging, and extended range by trimming conservative buffers, and early detection of microscopic faults.
As XPENG pursued next-generation mobility solutions, it required a step change in battery intelligence. EIS stood out as the enabling technology. By working closely together, we advanced both the implementation and application of EIS—unlocking deeper insight into battery behavior and accelerating innovation beyond what either of us could achieve independently.Chirag K.

XPENG’S CHALLENGE MEETS ADI’S EIS SOLUTION
XPENG Motors, known for AI-driven EVs, has ambitions that extend to broader applications where battery reliability is mission-critical. This expansion demanded a battery management architecture capable of supporting high-voltage, fast-charging while ensuring safety and longevity across platforms with very different thermal and performance profiles. Conventional monitoring approaches would fall short of delivering the predictive insight XPENG needed.
This is where XPENG’s ongoing partnership with ADI paid off. Having already deployed ADI technologies such as DSPs, ADI A2B™, and GMSL™, XPENG was well-positioned to adopt ADI’s EIS as the next step. That confidence was further strengthened by ADI’s delivery of a mass production-proven EIS solution, demonstrating clear leadership in bringing the technology to scale.
ADI’s latest BMS devices (ADBMS6842, ADBMS2970, ADBMS6822) use multi-frequency impedance analysis to reveal internal electrochemical conditions, enabling early detection of degradation and failure risks. Beyond hardware, ADI provided system-level design expertise, ADI BLISS™ system software, and direct algorithm collaboration that resulted in a unified BMS architecture that now scales across XPENG EVs and future mobility platforms.
A COMMITTED PARTNERSHIP, A COMMON GOAL
ADI’s commitment to XPENG extended to the executive level, with senior leadership engagement reinforcing the strategic importance of the collaboration. This strategic partnership transcended a typical supplier-customer relationship, grounded in a shared goal of advancing battery management through EIS.
Throughout the engagement, ADI provided full system solution support from the architectural design to implementation—helping solve problems all along the way.
A key aspect of the partnership was ADI’s support office located near XPENG’s operations that enabled frequent face-to-face collaboration between engineering teams—helping to provide smooth integration, and accelerated problem-solving, through real-time tech support.
THE ADI EIS EDGE
Analog Devices delivers EIS technology across one of the widest frequency ranges in the industry, extracting clean, actionable battery health data. While others offer basic impedance monitoring, only the ADI BLISS portfolio integrates comprehensive cell and pack monitoring with sophisticated system-level algorithms that transform raw impedance measurements into predictive intelligence.
Benefits of ADI EIS Integration
Non-Destructive Safety Monitoring
Continuously measures internal chemistry across multiple frequencies without stressing batteries, ensuring safe operation in critical applications like EVs, data centers, and industrial robotics while preserving cell integrity.
Accurate Health Tracking
Multi-frequency impedance analysis detects chemical changes and degradation over time, determining state of health (SOH) and state of charge (SOC) far beyond standard voltage measurements.
Production-Ready Integration
Embeds EIS directly into battery management ICs (BMICs) and analog front ends (AFEs), transforming laboratory techniques into revolutionary solutions for leading products like EVs, aircraft, grid storage, and humanoid robots.
Predictive Cost Savings
Identifies internal degradation before critical failure, enabling predictive maintenance that drastically reduces replacement costs, prevents unexpected downtime, and precisely indicates when batteries require service.
Enhanced System Intelligence
Provides unprecedented visibility into battery performance, enabling advanced, resilient battery management systems that optimize charging, extend lifespan, and make smarter operational decisions.
THE FUTURE’S LOOKING UP FOR XPENG WITH ADI’S EIS
The ADI-XPENG collaboration is much more than a product launch. It’s the foundation of a technological partnership that could transform mobility sectors. XPENG and ADI have brought EIS measurement into mass production EV batteries—unlocking a rich, continuous dataset from inside the cell that transforms battery management from reactive monitoring to predictive intelligence.
This co-development of the complete EIS solution architecture helped ADI and XPENG create platform scalability spanning next-generation EVs.
