It could be inaccurate to explain the Korean auto trade as firing on all cylinders, if solely as a result of it is also actually good at making electrical automobiles, and people do not have cylinders that fireplace. The electrical variations of the Hyundai Kona, Kia Soul, and Kia Niro are about the one battery EVs to strategy the vary effectivity of class-leading Tesla, and it makes a fairly wonderful hydrogen fuel cell EV as nicely.
On Tuesday, Hyundai Motor Group (which owns Hyundai and Kia, in addition to Genesis) confirmed us what comes subsequent. It is referred to as E-GMP, and it is the group’s new modular BEV platform for greater automobiles (analogous to Volkswagen Group’s PPE architecture). Hyundai Motor Group has huge plans for E-GMP—1,000,000 automobile cut up over 23 new fashions by 2025, with the primary two hitting showrooms sometime in 2021.
The tech specs are equally spectacular: an all-800V electrical structure; bi-directional charging; DC quick charging to 80 % in 18 minutes; and a WLTP vary of 500km (310 miles).
The platform is designed to construct both rear-wheel drive or all-wheel drive BEVs, with the battery pack sandwiched between the axles. It is extremely modular, which suggests the varied manufacturers can use it to create all the pieces from modern sedans just like the manufacturing model of the Prophecy idea (to be referred to as the Ioniq 6, due in 2022) to seven-seat SUVs (the Ioniq 7, due by 2024).
Throughout the drive models the oil-cooled motor-generator makes use of hairpin windings (like those in the Porsche Taycan motors), which make for extra environment friendly coils with much less empty house. The transmission is built-in into the unit, as is the inverter, which makes use of extra environment friendly silicon carbide semiconductors that enhance vary by about 5 %.
The principle drive unit appears to be like fairly compact, and Hyundai says that it is ready to spin 70-percent sooner and use a 33-percent greater differential ratio, giving it a lot improved greater torque density in comparison with its present electrical motor. When configured for all-wheel drive, the entrance drive unit is fitted with a transmission disconnect that may fully decouple that drive unit from the axle for higher effectivity when wanted.
The corporate is not ready to speak about kW or Nm simply but, though we should always count on efficiency BEVs with round 447kW (600hp) on the high finish, in keeping with Albert Biermann, head of Hyundai Motor Group’s R&D division.
The battery pack makes use of standardized modules made up of particular person pouch cells, with the variety of modules primarily based on every automobile’s necessities. The lithium-ion cells will proceed to make use of nickel-magnesium-cobalt chemistry, a minimum of till such time as different cell chemistries show superior.
The E-GMP pack feels like a a lot less complicated design than the group’s present battery packs, with 40-percent fewer half sorts and 60-percent fewer elements in complete. That makes the pack extra compact, which Hyundai says makes life simpler for the cooling block—positioned beneath the modules—because of minimized warmth switch pathways. In complete, the less complicated design resulted in a 10-percent improve in vitality density, the corporate instructed us.
The mix of extra environment friendly cooling and an 800V signifies that a 350kW DC quick charger ought to take an E-GMP battery’s state of cost from 5 to 80 % in simply 18 minutes, which is frankly spectacular. An E-GMP BEV may use the extra frequent 400V DC quick chargers, utilizing its inverter to transform 400V into 800V for the battery. (Sadly we weren’t in a position to get extra particulars of how this works, however I will attempt to discover out.)
Bidirectional charging is a characteristic request we see within the feedback fairly frequently, and it is a characteristic that E-GMP helps courtesy of a brand new built-in charging controller unit. It is in a position to provide as much as 3.5kW of AC energy (110V or 220V) and might “function a mid-sized air conditioner unit and a 55-inch tv for as much as 24 hours.” You possibly can even cost one other BEV utilizing an E-GMP automobile.
The primary E-GMP automobiles—a midsize SUV referred to as the Ioniq 5 and a Kia-badged BEV—are due subsequent yr.
