Hyundai Motor Group (Hyundai, Kia, Chuangshi brand) officially released a brand-new dedicated electric vehicle platform-Electric Vehicle-Global Modular Platform (E-GMP). Starting from 202 1, the platform will be used for the next generation of vehicles. By 2025, the company plans to launch 23 all-electric vehicles, including 1 1 special purpose vehicles. By then, the total sales volume will reach 6,543,800+0,000 vehicles.
First of all, E-GMP can be very flexible in developing various types of cars, from cars, CUVs to SUVs. It will also be covered on mainstream models and high-performance models. Modern companies have done a lot of work to ensure the modularity, standardization and comprehensiveness of E-GMP to meet various needs.
On the brand-new modular platform, the development and production process of new BEV models will be simplified and the cost will be reduced. Longer wheelbase, short suspension, slender cockpit module and flat floor can provide excellent driving force and efficiency, as well as more spacious interior space. At the same time, in order to improve the comfort, a five-link rear suspension system will be adopted.
E-GMP is specially designed for BEV. Compared with the existing platform of the Group, E-GMP has many advantages. These platforms are mainly designed to adapt to internal combustion engines. Its advantages are: improving the flexibility of development, providing powerful driving performance, increasing mileage, strengthening safety functions and providing more internal space for passengers and luggage.
Hyundai Motor Group said that E-GMP will allow the provided models to have extremely competitive performance.
Using WLTP standard, the maximum cruising range of a single charge exceeds 500 kilometers (3 1 1 mile).
The acceleration time of 0- 100 km/h (62 mph) is less than 3.5 seconds.
The top speed can reach 260 km/h (162 mph).
350? kW？ (800? V), 80% charging should be realized within 18 minutes.
Of course, not all models can have top-level data to the maximum, but it is possible.
Driving:
Setting of rear wheel drive (RWD) or dual-motor all-wheel drive (AWD). The foundation is a single-motor rear-drive model, and the all-drive version has an additional motor at the front end, which can be physically disconnected when not in use, improving efficiency. The all-wheel drive system includes an electric vehicle transmission isolating switch, which can control the connection between the additional motor and the front wheel and switch between the two-wheel drive mode and the all-wheel drive mode, so as to provide ideal power or performance level for the current driving condition, thus improving efficiency.
The world's first mass-produced integrated drive axle (IDA) is a compact module consisting of a motor, a frequency converter and a single-speed transmission. New high-speed motor (possibly up to 20,000? Rpms), using hairpin winding. This ensures strong performance, and the highest speed of the motor is 70% higher than that of the existing motor. While providing the same performance, high-speed motors are smaller and more efficient in space and weight than other motors.
Silicon carbide (SiC) power electronic device (inverter) for traction motor. This kind of motor can improve the efficiency of the system by about 2%~3%, that is to say, under the same battery energy, the vehicle can travel for about 5% more time.
In terms of charging:
Fast charging capacity up to 350? kW(800？ Chapter 5. 80% charging should be completed within 18 minutes, and it should take about 5 minutes to increase the battery life of 100 km (62 miles).
Integrated Charge Control Unit (ICCU)-Multi-channel charging (800V/400V) and bidirectional charging. The standard DC fast charging capacity is 800V V. Multiple charging system is the first patented technology in the world. It can operate the motor and inverter to boost 400V to 800 V, thus achieving stable charging compatibility. 1 phase and 3-phase AC charging, the new vehicle-to-load (V2L) function can release energy from the vehicle battery without additional components (the maximum power is 3.5 kW at11220 V).
In terms of batteries:
The battery pack is installed under the floor and between the axles.
There is no more information about the battery capacity. Depending on the specific configuration of the vehicle, the battery capacity may be between 50 and 100 kWh.
All E-GMP will use the same, standardized single-type battery module, which consists of bag-type standard batteries. In addition, the standardized battery system can also be adjusted to provide performance suitable for specific automotive fields, maximize mileage, or meet various needs of customers.
The battery pack will be the largest power density system in the history of Hyundai Motor Group. This is partly due to its enhanced cooling performance, which is the result of the new independent cooling block structure, which helps to make the battery pack more compact. Compared with the existing battery technology for electric vehicles, the energy density is increased by about 10%, and the battery pack is lighter, which can be installed in the lower position of the car body and release more cab space.
Optimum front and rear weight distribution combined with low center of gravity design.
