What does the battery passport feature of Ginkgo’s lithium‑ion battery products entail? Why was this feature introduced, and what problems does it address?
The commodity market inevitably harbors a mix of legitimate and dubious players, as the less transparent the information, the greater the scope for profit.
With the rapid advancement of lithium‑ion batteries in both power‑train and energy‑storage applications, the market is flooded with products of widely varying quality, making it difficult for consumers to distinguish between them and leading to frequent safety incidents. Two key factors underlie this situation: first, industry regulation tends to lag behind technological progress, and the adoption of standardized specifications and certification processes unfolds gradually. As a result, the battery cells that determine fundamental safety are not adequately controlled, allowing high‑quality, substandard, and second‑life cells to compete on the same playing field. In some sectors, this has even given rise to the “bad money drives out good” phenomenon. Second, the classification of “A‑grade” cells currently exists only as an internal corporate label; individual manufacturers use various performance metrics to assign A, B, C, or D grades to their own cell production, leaving consumers without a unified benchmark for assessing battery quality and hindering effective comparison and informed purchasing decisions.
In response to industry concerns about product quality, Ginkgo has launched its own proprietary lithium‑battery products alongside a Battery Passport feature. This passport is presented as an intuitive QR code affixed to the battery’s exterior. Using Ginkgo’s dedicated mobile app, users can scan the QR code to access detailed information on the battery pack’s manufacturing history, specifications, and key component data—such as the brand and production batch of the BMS/protective circuit board, as well as the brand, specifications, production date, and batch number of each individual cell. This empowers consumers to easily determine whether the battery pack incorporates a basic protective circuit board or an advanced intelligent BMS, and to verify that the cells are from a reputable manufacturer, identify their material chemistry, and confirm whether they are brand‑new, Grade‑A cells.
The battery passport feature makes the internal configuration information of battery packs publicly available and transparent, enabling consumers to verify and trace product quality, use batteries with greater confidence, and bolster trust in the lithium‑battery market. At the same time, it plays a crucial role in safeguarding consumer rights, strengthening industry oversight, fostering enterprise development, and driving technological advancement.
