Hyundai E-GMP will be the architecture of future Hyundai EVs

By Divyank K. Bansal | on December 3, 2020

With Hyundai's all-new Electric-Global Modular Platform (E-GMP), an EV will be able to act as a standalone power source, support an 800V charging infrastructure and offer 100kms of range with just a five-minute charge.

Hyundai Motor Group has unveiled its all-new dedicated battery electric vehicle (BEV) platform, the Electric-Global Modular Platform (E-GMP). Armed with the Korean marque's latest and world-first EV tech, the E-GMP will underpin Hyundai Motor Group's next-generation of EVs. The first models to be based on the E-GMP will most likely be the Hyundai IONIQ 5 (a compact crossover based on the Hyundai 45 Concept) and Kia's first dedicated EV (codenamed 'CV'), which will be revealed next year.

Apart from featuring flexible, modular construction, the E-GMP has also been developed to give birth to a new generation of EVs with rear-wheel drive. This is a big shift from the current front-wheel-drive layout, and it is an important step towards making more dynamic, driver-engaging EVs. To this end, Hyundai has claimed that a high-performance model based on the E-GMP 'will accelerate from zero to 100kph in less than 3.5 seconds and achieve a maximum speed of 260km/h.'

The E-GMP’s new Power Electric (PE) system consists of a smaller, more powerful motor, transmission, and inverter, all integrated into a single compact module. The motor, though smaller than before, is a high-speed unit with up to 70% higher maximum speed than the outgoing motor. The E-GMP will also be capable of offering an EV driver the option to switch to all-wheel drive, thanks to the presence of an additional motor and a transmission disconnector (both of which are easily integrable).

The E-GMP will also feature 'the most power-dense system that Hyundai Motor Group has ever created.' By creating a separate cooling block structure, engineers have been able to make the battery pack more compact and lighter than before, with up to 10% more energy density compared to existing EV battery technology. As a result, the battery can be mounted further lower, giving the vehicle higher stability, owing to a lower centre of gravity. According to Hyundai, EVs based on E-GMP will also be able to offer a range of over 500kms on a full charge (WLTP) and can be charged up to 80% within 18 minutes through fast-charging.

Perhaps the most significant achievement of the E-GMP is the introduction of a world's first multi (800V & 400V) and bi-directional charging system. Unlike most existing EVs and fast-charging infrastructures that provide 50kW~150kW charging capacity for EVs equipped with a 400V system, the E-GMP will offer an 800V charging system (with up to 350kW capacity) as standard and will also be able to support 400V charging, without requiring any additional components or adapters.

Unlike conventional EVs, which only accept one-way charging, the E-GMP’s Integrated Charging Control Unit (ICCU) has been designed to overcome the limitation of the current On-Board Chargers (OBC). Thus, the ICCU enables a new Vehicle-to-Load (V2L) function, which can additionally discharge energy from the vehicle battery without additional components. With this bi-directional charging system, an EV based on the E-GMP can act as a power source, capable of operating electric machinery (110V – 220V) anywhere. With a maximum power supply of 3.5kW, the V2L function can power a small air-conditioner or a 55-inch television for up to 24 hours!
