Hyundai’s dedicated new Electric-Global Modular Platform - 'E-GMP' - is said to provide exceptional all-new capabilities. Wayne Gerdes – CleanMPG – Dec. 1, 2020 Hyundai E-GMP Introduction Like many OEMs, Hyundai has now unveiled its own all-new Electric-Global Modular Platform (E-GMP), a dedicated battery electric vehicle (BEV) platform. Beginning in 2021, the E-GMP will underpin a range of dedicated new BEVs, including Hyundai’s upcoming and highly anticipated IONIQ 5. E-GMP provides various advantages including increased R&D flexibility, performance, much longer range, safer platform, plus as an added benefit, even more passenger and cargo volume! Like all skateboard BEV platforms, E-GMP reduces complexity through modularization and standardization allowing one chassis/drivetrain platform to underpin sedans, SUVs and CUVs. Hyundai touted one of its performance models will accelerate from zero to 60 in less than 3.4 seconds and achieve a maximum speed > 160 mph. With its inherent low center of gravity and close to 50/50 weight distribution, E-GMP is engineered to offer improved cornering performance and driving stability at any speed. The high-speed electric motor raises the driving performance of E-GMP vehicles. A five-link rear suspension system and the world’s first integrated drive axle (IDA), which combines wheel bearings with the drive shaft to transmit power to the wheels, improves both ride comfort and handling stability. The platform secures the large traction battery through a support structure made of ultra-high strength hot-stamped steel. E-GMP maximizes interior space through its long wheelbase, short front and rear overhangs and slim cockpit module. With the battery pack mounted beneath the floor, the E-GMP creates a flat floor for the cabin. This provides more legroom for passengers, while enabling various arrangements for the front and rear seats. The battery pack itself will be the most power-dense system that Hyundai has ever created. This is partly due to its enhanced cooling performance, a result of a new separate cooling block structure. With energy density enhanced by around 10% compared to existing EV battery technology, the battery modules and structure are lighter, can be mounted lower in the body, and liberate more cabin space. Hyundai has not yet disclosed any energy storage or mass specs however. Hyundai E-GMP Cutaway E-GMP consists of a powerful motor, EV transmission and inverter. These three components are integrated into a single compact module. This ensures powerful performance by raising the motor’s maximum speed by up to 70 percent compared to existing motors. The high-speed motor is smaller than other motors while providing comparable performance, and it gives efficiencies in both space and weight. Additionally, a standardized battery system can be tuned to offer performance appropriate for a specific vehicle segment, to maximize driving range, or increase performance. The motor is controlled by the inverter power module, which adopts silicon carbide (SiC) semiconductors. This motor can enhance system efficiency by around 2~3 percent, which means the vehicle can be driven for approximately 5 percent longer on the same battery energy. E-GMP relies on the rear wheels for propulsion in RWD trims. Customers can also choose AWD configurations with an additional motor up front. The all-wheel drive system includes an EV transmission disconnector can switch between RWD and AWD to enhance efficiency or performance for a given driving situation. All vehicles developed with the E-GMP platform use a standardized single type of battery module in different quantities as required for each vehicle The big news is E-GMP includes Multi (800V and 400V) and Bi-Directional Charging! Most modern BEVs can be charged at 50 to 150kWs with a 400 to 500V system. With the development of 800V infrastructure and up to 350kW charging, even faster charging will soon become the norm. E-GMP offers 800V charging capability as standard and enables 400V charging, without the need for additional components or adapters. The multi-charging system is a world’s first patented technology which operates the motor and the inverter to boost 400V to 800V for stable charging compatibility. A BEV based on E-GMP is capable of a maximum range of over 300 miles with a fully charged battery, according to the Worldwide Harmonized Light-duty vehicle Procedure (WLTP). Moreover, it can high-speed charge up to 80 percent in just 18 minutes and can add up to 60-miles of driving range in just five minutes. The E-GMP’s charging system and its Integrated Charging Control Unit (ICCU) allows the platform to operate other 110/220V devices anywhere. The system can even be used to charge another EV! With up to 3.5 kW discharge power, the platform has enough storage to operate a mid-sized air conditioner and a 55” TV for up to 24 hours. Hyundai E-GMP The future of Hyundai/Kia is shown above. E-GMP Will Underpin Future Hyundai/Kia EVs Globally E-GMP will underpin a total of 23 Hyundai and Kia BEV models including 11 dedicated BEV models with sales projected to reach 1 million worldwide by 2025. Hyundai’s dedicated ‘IONIQ’ BEV will be the first with three dedicated BEV models, the IONIQ 5, 6 and 7 by 2024.
