Hyundai E-GMP (Electric Global Modular Platform) is a dedicated
It follows Hyundai's earlier Power Electric System (PE System), which describes the drivetrain of an electric vehicle, including the traction motor, storage battery, and power electronics.History
The PE System serves the same function for an electric vehicle as an
In 2017, Hyundai confirmed reports that it was developing a dedicated platform for electric vehicles; at the time, only a few manufacturers had done so.
The PE System has also been installed into the Hyundai Vision FK concept, an eco-friendly hydrogen electric vehicle. In this vehicle, the PE System has been combined with a hydrogen fuel cell system.[6]
A standardized battery system can be tuned and implemented as part of the system appropriate for a specific vehicle segment. This system is said to maximize driving range or meet the needs of a customer.[7]
Technical design
The E-GMP platform is an 800 V architecture with scalable wheelbase length, and supports batteries from multiple manufacturers. The motor, inverter, and transmission are integrated into a single powertrain unit.[8]
Traction motor
Both single motor 2WD (rear axle) and dual motor AWD are supported.[9] Hyundai claim the motor is approximately 10% more efficient than a conventional motor due to "hairpin winding technology", allowing the coils to be wound more densely, and more effective cooling.[10]
Reduction gear transmission
The transmission reduces the traction motor speed and applies torque to the driven axle. This effectively multiplies torque at the wheel for electric vehicles. In addition, an EV Transmission Disconnector is provided, which allows for the motor and drive axle to be disconnected, which enables free shifting between 2WD (two-wheel drive) and 4WD (four-wheel drive). This is only available for the all-wheel drive system.
Battery and charging
The
Current (as of 2022) DC fast charging infrastructure has a power and voltage of 50–350 kW and 400-920 V.[10] The E-GMP electronics support voltages of both 400 V and 800 V charging systems and offers bi-directional charging (V2L (110/230 V and up to 3.7 kW),[13] V2V and V2G).[11] The platform uses the vehicle's motor/inverter to convert incoming DC current at 400 V to 800 V.[8]
Inverter
The inverter converts
Chassis
The platform supports a wheelbase exceeding 3,000 mm (118.1 in).
The battery is attached to the full-perimeter frame using eight bolts running completely through the battery for strength. The front and rear crumple zones are designed to absorb and dissipate the energy of a potential impact, and high strength steel is used to protect the battery and passenger compartment.[10]
Applications
Hyundai plan to release 23 battery electric vehicles, including 11 exclusively electric vehicles, using the E-GMP platform.[12]

It's just too good to give up on [our current lineup of ICE-platform-based electric vehicles such as the Kia Niro EV, Hyundai Kona EV and Ioniq EV], so we will continue with derivative EVs based on our next-generation front-wheel-drive platform and of course they will become even more efficient with better performance. We will follow both ways.
