Hyundai to Halve EV Slow Charging Time with New Platforms

Hyundai plans to cut the slow charging time of its electric vehicles by 50%, thanks to its upcoming eM and eS platforms. These advancements promise faster charging at home and work, enhancing convenience and reducing consumer costs.

Hyundai's New EV Platforms to Cut Slow Charging Time by 50%, Boost Battery Capacity and Motor Output

According to Hyundai's most recent sustainability report (via Electrive), the company is contemplating a 50% decrease in slow-charging time compared to current levels by implementing its next-generation dedicated EV platforms. The company is creating an 'eM' platform for passenger electric vehicles (EVs) and an 'eS' platform for purpose-built vehicles (PBVs). It intends to augment battery capacity by 40% and motor output by 28%, in addition to expediting the slow-charging process.

The Ioniq 5 N has Hyundai's most recent battery cell and a 10.5 kW three-phase on-board charger. This 84-kWh lithium-ion battery pack is equipped with the company's fourth-generation technology and requires seven hours and 35 minutes to be charged entirely.

If Hyundai significantly reduces the AC charging time, such as in the case of the Ioniq 5 N, to under four hours, consumers may not be required to leave their EVs charging overnight. For instance, upon arriving at the office in the morning, they could charge their electric vehicle (EV) using an AC charger and ensure it is ultimately charged before the lunch break.

Furthermore, customers would experience a substantial reduction in their charging expenses and an extension of the battery pack's lifespan, which would result in even more significant savings in the long term, as they would be required to utilize DC converters less frequently. The burden on the power grid can also be reduced by reducing the use of DC chargers on a mass scale. Most manufacturers emphasize enhancing the DC charging input of their electric vehicles (EVs). Chinese companies such as Zeekr and Li Auto have achieved figures exceeding 500 kW. Nevertheless, the charging ecosystem may be more beneficial globally if AC charging is enhanced.

Hyundai to Debut eM Platform in Genesis GV90, Featuring Swiveling Seats and Advanced Driver Assistance

According to media reports, Hyundai intends to implement the eM platform initially in the Genesis GV90, a full-size three-row SUV. Hyundai's sluggish charging enhancements may also be implemented in the forthcoming flagship electric vehicle. The South Korean automaker has confirmed that eM platform-based EVs will feature novelty features such as swiveling seats in the first and second sections, a pop-up display, and Level 3+ advanced driver assistance functions.

Hyundai intends to offer eM platform-based EVs equipped with cell-to-module battery packs with higher energy density than the cell-to-module units of the models based on the Electronic Modular Platform (E-GMP). In addition, the organization will implement LFP cells instead of NCM cells to maintain a competitive price point for certain lower-end vehicles.

In contrast to E-GMP, the eM platform will encompass a broader spectrum of model segments, ranging from B to E. Hyundai announced at its 2023 CEO Investor Day event that it will introduce four mainstream EVs and five Genesis EVs that are built on the new modular chassis between 2025 and 2030. Additionally, Kia disclosed that it will implement an identical platform for four electric vehicles during that time.
