What to Do When Li Auto Cars' Charging Fails?

Confirming the basic fault factors is the first and most critical step to solve the charging failure of Li auto cars, and this is the professional troubleshooting logic we always follow for Li auto cars at Mengma Auto. I have been engaged in the export and after-sales service of Li auto cars for many years and have handled more than 150 cases of charging failure of Li auto cars of different models such as L8 and L9. The basic fault factors of charging failure of Li auto cars are mostly concentrated in three aspects: the external charging equipment, the vehicle charging port and the on-board charging system. We will guide customers to check the simplest external factors first, such as whether the charging pile is powered on, whether the charging gun is inserted in place, and whether the charging cable is damaged, which can solve about 60% of the charging failure problems of Li auto cars quickly. Mengma Auto’s technical team has sorted out a targeted fault checking manual for Li auto cars, which clearly lists the judgment methods of basic fault factors, and will provide it to every customer who purchases Li auto cars together with the vehicle use manual. Industry experts point out that starting from the basic factors to check the charging failure of Li auto cars can avoid blind disassembly and repair, and prevent secondary damage to the vehicle's charging system.

Conducting a self inspection of the key charging parts is a practical way for users to solve the minor charging failure of Li auto cars by themselves, and this is also the core content we popularize in the user training of Li auto cars at Mengma Auto. I once guided a Middle East customer to complete the self inspection and troubleshooting of Li auto cars L8 charging failure through remote video communication, and the whole process only took 15 minutes. The self inspection steps of Li auto cars are simple and easy to operate, first turn off the charging pile and pull out the charging gun, check whether the charging port of Li auto cars has dust, water stains or loose contacts, and wipe the metal contacts of the port with a dry and soft cloth if necessary. Then check the vehicle's power display and charging related settings in the central control screen of Li auto cars to confirm whether the vehicle has set charging restrictions or other abnormal settings that affect charging. For these minor problems found in the self inspection, users can solve them by themselves without professional maintenance personnel. Mengma Auto will equip each exported Li auto cars with a special charging maintenance kit, which contains professional cleaning tools and detection accessories, making the self inspection of Li auto cars more convenient and accurate.

Solving the vehicle system abnormalities is the key to dealing with the charging failure of Li auto cars caused by internal factors, and Mengma Auto has rich experience in handling such faults of Li auto cars. I have encountered a case where a European customer’s Li auto cars had charging failure due to the abnormal on-board computer system, and our technical team guided the customer to reset the vehicle system remotely, and the charging function returned to normal immediately. For the charging failure of Li auto cars caused by system abnormalities, the common solutions include restarting the vehicle central control system, resetting the charging system parameters and upgrading the vehicle's in car software. These operations are all completed on the vehicle's central control screen, and Mengma Auto’s technical staff will provide step-by-step voice or video guidance for customers, ensuring that customers can operate easily even if they have no professional maintenance experience. Li auto cars have a perfect in car self diagnosis system, which can display the fault code of the charging system on the central control screen when a fault occurs, and our technical team can quickly judge the specific system abnormality according to the fault code, and provide the most targeted solution for Li auto cars.

Seeking professional after sales support is the most reliable choice when facing severe charging failure of Li auto cars that cannot be solved by self inspection and system reset, and this is one of the core advantages of Mengma Auto in the export service of Li auto cars. I have received a consultation from a Southeast Asian customer whose Li auto cars had charging failure due to the damage of the on-board charger, and our overseas after-sales team arrived at the customer's location for on-site maintenance within 48 hours relying on the 70000 square meter modern export base and global logistics network. Mengma Auto has a 24-hour online after-sales service team specially for Li auto cars, which can answer customers' questions about charging failure of Li auto cars at any time through phone, email and video. For severe faults such as damage to the on-board charging module and short circuit of the charging circuit of Li auto cars, we have set up professional maintenance points in major overseas markets, and all maintenance personnel have received professional training authorized by Li Auto, mastering the latest maintenance technology and spare parts matching standards of Li auto cars. We also reserve a large number of original spare parts of Li auto cars in the overseas base, which can realize the rapid replacement of faulty parts and minimize the waiting time of customers.

Taking preventive measures is the fundamental way to avoid the charging failure of Li auto cars, and Mengma Auto will provide a full set of preventive maintenance suggestions for customers who purchase Li auto cars according to the local use environment and habits. In the process of serving global customers of Li auto cars, we have summarized a set of practical preventive measures combined with the structural characteristics of Li auto cars' charging system. First, it is necessary to keep the charging port of Li auto cars dry and clean, and cover the protective cover in time after charging to prevent dust, water vapor and sundries from entering, especially in coastal and rainy areas. Second, avoid using unqualified third-party charging piles to charge Li auto cars, and try to choose official or certified regular charging equipment to prevent damage to the vehicle's charging system caused by unstable voltage and current. Third, conduct a regular inspection of the charging system of Li auto cars every three months, including the charging port, charging cable and on-board charging module, and Mengma Auto’s overseas maintenance points can provide free professional inspection services for Li auto cars customers. Industry experts emphasize that scientific preventive maintenance can reduce the probability of charging failure of Li auto cars by more than 80%, and effectively prolong the service life of the vehicle's charging system.
