Unprecedented Warranty Terms for Electric Vehicles
Tech giant Xiaomi has officially announced a new warranty framework for its Longjia traction battery series, commercially known as the Dragon Armor system. The defining highlight of this policy is the full financial liability assumed by the company in the event of thermal runaway or fire incidents related to the battery structure.
Xiaomi Automotive aims to eliminate consumer hesitation regarding battery reliability and fire hazards. According to official representatives, if a vehicle suffers severe damage or total loss due to an internal battery manufacturing defect, Xiaomi will fully compensate the car’s market value or supply a brand-new replacement vehicle.
Detailed Terms and Compensation Scenarios
The guarantee framework covers multiple scenarios, addressing both hardware manufacturing risks and operational hazards encountered on public roads.
- Thermal Runaway from Internal Defects – If a fire originates from cell defects or Battery Management System (BMS) failures without external intervention, Xiaomi covers 100.0% of the financial loss. The owner receives full monetary reimbursement or a replacement vehicle.
- Underbody Impact Damage – If a fire is triggered by a severe bottom strike or puncture while driving, a dual-coverage mechanism applies. Primary insurance pays out first, and Xiaomi covers any remaining financial gap to ensure zero out-of-pocket loss for the owner.
- Lifetime Coverage Duration – Core terms regarding manufacturing protection remain valid throughout the operational lifespan of the battery pack, establishing one of the most aggressive commitment policies in the EV sector.
Technical Specifications of the Dragon Armor System
The company’s confidence stems from structural engineering built into the battery pack architecture. The design incorporates multi-layered thermal barriers and physical shielding around every individual cell module.
Engineering Features for Fire Prevention
The Longjia battery system utilizes an advanced cell layout combined with active liquid cooling channels. The bottom casing is reinforced by a three-layer armored shield engineered to absorb high-velocity impacts from road debris.
Integrated liquid cooling loops work alongside AI-driven diagnostic sensors. The system continuously evaluates individual cell temperature and voltage parameters, identifying micro-anomalies long before thermal runaway can escalate.
Pressure Relief Vent Design
In the event of localized cell damage, dedicated pressure relief vents redirect hot gases and flame paths away from the cabin area and adjacent battery modules. This design prevents cascading thermal propagation across the entire pack, isolating hazards within a single compartment.
Industry Impact and Market Implications
This warranty initiative sets a high benchmark across the global electric vehicle sector. Most legacy automakers constrain battery warranties to simple capacity degradation metrics (typically 8 years or 100,000 miles) and rarely provide direct financial guarantees against fire-related vehicle losses outside standard insurance claims.
Xiaomi’s strategy is designed to build trust around its expanding automotive ecosystem. As a relatively new contender in the EV industry, such bold guarantee commitments serve as a major competitive advantage, encouraging broader adoption among cautious buyers.
