The Hyundai Motor Group revealed this Tuesday (01) a platform on which it will base its future battery electric vehicles (BEV). Named E-GMP (Electric-Global Modular Platform), it will offer drivers “powerful” performance, greater autonomy, more safety features and greater interior space for occupants and luggage.
The first vehicles to use the platform will be the IONIQ 5, owned by Hyundai, and Kia Motors' first battery-powered electric vehicle, which will be unveiled in 2021. The group plans to launch 23 BEVs and reach a total sales volume of 1 million units by 2025.
Using modularization and standardization, E-GMP reduces design complexity, allowing for the rapid and flexible development of electric vehicles. They can be used in various market segments and satisfy the performance needs of different types of consumers. As an example, Hyundai cites that a high-performance BEV based on the E-GMP will accelerate from 0 to 100 km / h in less than 3,5 seconds and reach a top speed of 260 km / h.
The platform was designed to offer better cornering performance and more stability at high speed. This is due to the weight distribution between the front and rear, which combined with the Batteries installed between the front and rear axles give the vehicle a low center of gravity.
The battery's support structure uses “ultra-high strength” steel. Chassis and vehicle body areas are designed to direct and absorb energy from an eventual collision, minimizing the impact on the electrical system and the battery. In addition, the distribution of loads on the A-pillar prevents deformation of the passenger compartment.
Fast charging electric vehicles
Motor, transmission and inverter are integrated in a single component. According to Hyundai, this makes it possible to increase the maximum engine speed by 70%, compared to existing models. This engine is smaller than the ones already on the market, although it offers comparable performance.
By default, E-GMP-based vehicles have rear-wheel drive, but four-wheel drive versions will be available. These can be equipped with an extra engine. All will use a standardized battery module, with “bag” cells grouped in different quantities, according to the needs of each model.
Another highlight of the new platform is the battery recharge system. According to Hyundai it is the first on the market capable of working with two different charging voltages, 400v and 800v. A car based on the E-GMP will have a range of up to 500 km. Eighteen minutes of charge is sufficient to recharge 80% of the battery, and 5 minutes adds 100 km autonomy.
BEVs based on E-GMP can also offer reverse load (Vehicle 2 Load, V2L), that is, it is possible use the car as a battery to power 110 or 220 volt electrical equipment, and even recharge another car. This feature can operate a “medium size” air conditioning unit and a 55 inch TV for “up to 24 hours”.
“E-GMP is the result of years of research and development and brings together our leading edge technologies. Our line of BEVs will evolve and become stronger thanks to this innovative platform, ”says Fayez Abdul Rahman, Senior Vice President, Vehicle Architecture Development Center, Hyundai Motor Group.
