Hyundai Electric Global Modular Platform
Hyundai E-GMP ("Electric Global Modular Platform") is a dedicated electric vehicle platform for Hyundai Motor Group . It is the first electric-only dedicated platform by Hyundai. It is to be used for Hyundai and Kia automobiles from 2021. Technical design. 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 platform is an 800 V architecture with scalable wheelbase length, and supports batteries from multiple manufacturers. Traction motor. Both single motor 2WD (rear axle) and dual motor AWD  are supported. The semiconductor power electronics will be silicon carbide-based for the rear (main) motor to minimize conversion losses and to facilitate its use in high-voltage and high-current circuits. The front motor, on vehicles so equipped, will use silicon-based power electronics to reduce costs. The motor, inverter, and transmission are integrated into a single unit. 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. Battery and charging. The Li-ion batteries are pouch-sized and  the battery-pack is designed to be tall. E-GMP vehicles are expected to have a range of at least under the WLTP test cycle. Vehicles will support 200 kW fast charging; Hyundai claim an 18-minute charge will restore 80% of capacity (80% SOC of 77.4kWh in 18 minutes) and a 5-minute charge will add of range when using a high-power (800 V/350 kW) DC fast charging supply. By standardizing the battery type and size, repairs can be carried out more economically by replacing a single module, rather than the entire battery pack. Hyundai claim that power  density has increased by 10% with the E-GMP. Current (as of 2020) DC fast charging infrastructure usually has a maximum power and voltage of 50–150 kW and 400 V. The electronics support both 400 V and 800 V charging and bi-directional charging (V2L (110/230 V and up to 3,5 kW), V2V and V2G). The platform uses the vehicle's motor/inverter to convert incoming DC current at 400 V to 800 V. Chassis. The platform supports a wheelbase exceeding . E-GMP supports various sizes and configurations of vehicles, including C-segment, E-segment, CUV, sedan, and SUV , including three-row SUVs with seven seats. Albert Biermann stated that "existing [derivative] EVs on ICEV platforms will see some expansions into smaller segments", which was clarified to mean that smaller EVs would continue to use a front-wheel-drive platform. The rear suspension uses a five-link arrangement. An integrated drive axle is used, in which the drive shaft and wheel bearings are a single unit; this reduces the number of parts and increases rigidity. 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. Applications. Hyundai plan to release 23 battery electric vehicles, including 11 exclusively electric vehicles, using the E-GMP platform. Models released: Upcoming models:
