The Emgrand LHI-X is an electric vehicle, and its charging system is standard when the vehicle leaves the factory, and in general, it cannot be changed at will. The charging system of electric vehicles includes on-board chargers and ground charging facilities, which need to cooperate with each other to complete the charging process.
If your Emgrand LHI-X original charger doesn't meet your charging needs, or you want a faster charging speed, then you may want to consider replacing it with a faster charger. However, this will require support from your electric vehicle manufacturer and may require some adjustments to the vehicle's circuit system.
At the same time, fast charging may have a certain impact on the life of the battery, so you need to weigh the pros and cons when deciding whether to switch to fast charging. Finally, any modifications to the vehicle's electrical system should be carried out by professional technicians to avoid causing safety accidents.
