On December 2, Hyundai Motor Group held the "E-GMP Digital Discovery" event to introduce the technical advantages of the new electric vehicle dedicated platform E-GMP and released a new high-speed motor and battery system . With this, Hyundai Motor Group's new electric vehicle-specific platform - E-GMP (Electric-Global Modular Platform) will be committed to following the hydrogen fuel cell vehicle in the field of pure electric vehicles. Ensure leading market position.
1. The world’s first 400V/800V multi-function fast charging system:
The E-GMP platform is equipped with a 400V/800V multi-function fast charging system, which is suitable for 800V ultra-high-speed charging systems and other types of charging infrastructure. Using ultra-high-speed charging facilities, the vehicle can be charged to 80% in 14 minutes and can travel 600km when fully charged (NEDC standard working conditions). In addition, even if it is charged for only 5 minutes, it can travel about 100km. As the world's first patented technology applied to the E-GMP platform, this multifunctional fast charging system makes full use of the vehicle's drive motor and inverter to boost the 400V voltage provided by the charging infrastructure to the most suitable voltage for the vehicle system. 800V voltage, thus achieving stable charging compatibility.
2. Equipped with new PE systems such as high-efficiency motors and batteries that are most suitable for the E-GMP platform:
The F-GMP platform is equipped with a new PE system (Power? Electric? System), Covers newly developed motors, reducers, inverters to control motors, and batteries for the new generation of electric vehicles. The PE system of the E-GMP platform reduces the overall volume and weight, reduces the loss of energy transfer between components, and maximizes performance and efficiency. It also uses an 800V high-voltage system, which greatly shortens charging time.
The E-GMP platform comes standard with a rear-wheel drive 2WD mode, and depending on the configuration, a front-wheel motor can be added to achieve a 4WD drive mode. At the same time, electric vehicles are equipped with a "reducer isolation switch" (power separation device), which can separate or connect the motor and drive shaft according to driving conditions. Through this design, the vehicle can freely switch between 2WD and 4WD drive modes. .
The inverter power module of the rear wheel motor system uses silicon carbide (SiC) power semiconductors that are more efficient than existing silicon (Si). The system efficiency can be increased by 2~3%. The cruising range can be extended by about 5%, that is, it can travel longer distances with the same number of batteries.
3. E-GMP electric vehicle dedicated platform to create a diversified electric vehicle lineup:
The E-GMP platform introduces the concepts of modularity and standardization, and begins to reduce the number of products in the product planning stage. The complexity of R&D enables flexible product development across models and levels. As a result, the E-GMP platform can realize the research and development of cars, CUVs, and SUVs, as well as high-performance and energy-efficient models. With the E-GMP platform, various models that meet the diverse needs of customers can be quickly launched.
To this end, Hyundai Motor launched the pure electric vehicle brand "IONIQ" in August this year, planning to be the first to be equipped with the E-GMP platform dedicated to electric vehicles. From next year to 2024, It is the first to launch a product lineup covering three dedicated electric vehicle models: compact CUV, mid-size sedan and large SUV.
