Electrify Europe and ZEVA Global have launched a new over-the-air battery intelligence reporting platform designed to assess electric vehicle (EV) battery condition without requiring diagnostic hardware, workshop inspections, or physical vehicle access. Initially available for Tesla vehicles worldwide, the service seeks to provide a more comprehensive assessment of battery health than traditional state-of-health (SoH) measurements.
The companies argue that the EV industry has become overly reliant on SoH as the primary indicator of battery condition, despite the metric measuring only remaining battery capacity rather than the overall health of the battery system.
Moving Beyond State-of-Health Measurements
State of health is widely used across the automotive industry to estimate how much battery capacity remains compared to when the battery was new. However, Electrify Europe and ZEVA Global contend that capacity alone does not reveal critical issues that can affect battery performance, safety, and long-term reliability.
According to the companies, battery systems can experience problems including cell imbalance, moisture intrusion, battery management system (BMS) faults, and abnormal degradation patterns while still displaying relatively healthy SoH scores.
“A battery can display an acceptable state of health score while simultaneously exhibiting severe cell imbalance, moisture contamination, or battery management system faults. After years of diagnosing and repairing EV batteries, we’ve seen firsthand that capacity alone does not tell the full story,” said Sven Van Passel, Founder of Electrify Europe.
Rising Importance of Battery Transparency
The launch comes as growing numbers of electric vehicles enter the used-car market. According to figures cited by the companies from Cox Automotive and J.D. Power, off-lease EV volumes have increased between 185% and 230% year-on-year, creating greater demand for accurate battery condition assessments.
Battery health has become a key consideration for used EV buyers because battery replacement costs can reach tens of thousands of dollars, making the battery the most valuable and expensive component in many electric vehicles.
The new reporting platform is designed to provide owners, buyers, fleet operators, and other stakeholders with deeper insights into battery condition and potential risks throughout a vehicle’s lifecycle.
Remote Diagnostics Without Workshop Visits
The battery intelligence reports are generated remotely using over-the-air vehicle data, eliminating the need for physical diagnostic tools or service center appointments.
The system analyzes a broader range of battery performance indicators beyond remaining capacity, helping identify issues that may not be visible through conventional battery health checks.
“Consumers deserve greater transparency into the condition of the most expensive component in their vehicle. Our battery intelligence reporting helps owners identify potential issues earlier, better understand replacement risk, and make more informed decisions throughout the lifecycle of their vehicle,” said Cedric Blijweert, Managing Director of Electrify Europe.
Tesla Support Available Now
The service is currently available for Tesla vehicles globally, reflecting the manufacturer’s extensive connectivity capabilities and access to vehicle operating data.
Electrify Europe and ZEVA Global said support for additional vehicle manufacturers is planned over the coming year, potentially expanding the platform’s reach across a broader range of electric vehicle brands.
As the global EV fleet continues to age and used electric vehicle sales increase, more detailed battery diagnostics may become an increasingly important tool for assessing vehicle value, managing fleet performance, and supporting consumer confidence in the secondary EV market.
