The Legal Hurdle for Autonomous Taxis
Dragonscale’s Radical Battery Warranty

Battery safety has long been the Achilles' heel of the electric vehicle industry. Beyond the hurdles of cost and charging infrastructure, public perception has been shaped for years by high-profile incidents of thermal runaway. Today's technological leap allows for a paradigm shift, and Xiaomi intends to lead this transition with the introduction of its Dragonscale (Longjia) battery family.
At the heart of this strategy is the seamless integration of hardware and cloud-based monitoring. The development of Dragonscale was conducted in close partnership with industry leaders CALB and Sunwoda, resulting in a product that exceeds current Chinese national safety benchmarks. For the original owners of the Skynomad series, these batteries are backed by a lifetime guarantee. However, this privilege is not unconditional: it requires mandatory connection to the proprietary cloud telemetry service and regular maintenance at authorized service centers.
In essence, Xiaomi is implementing a predictive control system. Cloud-based health monitoring of the cells occurs ten times more frequently than required by government regulations, enabling the detection of anomalies at their earliest stages. Technical protection is implemented across multiple layers: additional insulators prevent the spread of flames within the structure, while an intelligent emergency cutoff mechanism instantly isolates defective cells from the main power supply.
The most striking aspect of the company's policy is its approach to compensation. Should a spontaneous combustion occur due to a manufacturing defect, the manufacturer commits to replacing the vehicle with a new one of identical specifications and trim. In cases where fire is caused by external factors—such as a collision or underbody damage—the terms are more pragmatic yet remain compelling: the company covers the difference between the insurance payout and the cost of a new vehicle.
Naturally, such generosity is bound by strict operational constraints. The guarantee does not extend to commercial vehicles, including taxis and ride-sharing services, where battery degradation occurs significantly faster. Furthermore, the right to this protection is voided upon the resale of the vehicle, underscoring the personal nature of this commitment.
With the market launch of the Skynomad N90 and N70 hybrids equipped with Dragonscale batteries, Xiaomi is effectively shifting the safety discourse from technical specifications to financial assurances. This demonstrates the brand's confidence that the era of "dangerous" batteries is finally becoming a thing of the past.
