Hyundai has revealed its new Electric-Global Modular Platform (E-GMP) that’ll underpin the Group’s next-generation BEVs. The Ioniq 5 and Kia’s first dedicated BEV are expected to debut in 2021 underpinned by this new platform.
Designed exclusively for BEVs, the E-GMP is claimed to offer various advantages over the Group’s existing platforms, which have been engineered predominantly to accommodate ICE powertrains. Benefits of E-GMP include driving performance, more range, more safety, fast charging, and of course, more interior space for occupants and their luggage.
As with most modern EVs today, the motor, EV transmission and inverter — these three components are integrated into a single compact module called power electric (PE) system, offering space and weight benefits. The inverter which controls the motor, features silicon carbide (SiC) semiconductors, which are claimed to enhance system efficiency by around 2-3%, resulting in approximately 5% longer range on the same battery energy.
The E-GMP will be rear-wheel-drive as standard, while there’ll be an option to add an additional front motor. The AWD models will feature an EV transmission disconnector, which can control the connection between the additional motor and front wheels, and switch between RWD and AWD modes to enhance efficiency.
Hyundai claims some big numbers for the BEVs based on this platform. A high performance model, for example, can accelerate from 0-100 km/h (62 mph) in less than 3.5 seconds and achieve a maximum speed of 260 km/h (161 mph). As for the range, Hyundai claims over 500 km (310+ mi) with a fully charged battery as per WLTP cycle.
Also, the E-GMP boasts a multi (800-volt and 400-volt) and bi-directional charging system. The models will especially benefit from the Ionity network in Europe that offers a charging capacity of up to 350 kW.
The multi-charging system is the world’s first patented technology which operates the motor and the inverter to boost 400V to 800V for stable charging compatibility.
If found a high-speed charger, up to 100 km (62 mi) range can be added in 5 minutes, and up to 80% can be filled up in 18 minutes, according to Hyundai.
