The voltage increases

The Hyundai Motor Company shows a new platform for electric cars; Hyundai and Kia want to present 23 new electric cars by 2025.

Hyundai’s new E-GMP platform. Cars with a length of up to five meters are possible on it.

The technology is developing rapidly: In order to be able to persuade more and more drivers to switch to an electric car, the manufacturers have to get rid of the common prejudices. This means that new models have to offer more range and shorter charging times. This is the only way to make the battery-electric car attractive to the masses. The South Korean Hyundai Motor Company, consisting of the Hyundai and Kia brands, wants to take a big step in this direction with the newly presented “E-GMP” platform. Based on this new architecture, more than ten new and independent electric models will be on the road by 2025; Overall, the group promises 23 new models or variants with electric drive within the next five years. The Koreans want to be able to sell one million electric cars worldwide by 2025.

More voltage in the battery

The core of the new platform is a battery installed flat in the underbody, as is now common in almost all new electric cars. In addition, there are a few interesting technical innovations: The system works with 800 volts instead of the usual 400 volts. Above all, the higher voltage enables faster charging: The battery should be 80% charged again in just 18 minutes. Or: electricity for up to 100 kilometers can be recharged in just five minutes. So far, only the Porsche Taycan can offer an 800-volt design.
Depending on the structure, more than 500 kilometers per charge should be possible according to the WLTP cycle, which suggests a battery capacity of around 100 kWh.
Models with rear-wheel or all-wheel drive are conceivable, with the all-wheel drive versions for the first time being able to completely decouple the front motor in order to improve efficiency. The electric model range will also include sporty “N” models from Hyundai. Because the technology should enable up to almost 600 hp, which means that the sprint to 100 km/h can be done in 3.5 seconds.

Share electricity and charge flexibly

Although the network of 800-volt charging stations is constantly being expanded, it is by no means as dense as the 400-volt charging stations that have been in use up to now; therefore the platform is designed to handle both voltages.
For the first time, the cars on the new “E-GMP” platform will also support bidirectional charging. This means that it will be possible to charge from car to car, so that you can, for example, help a broken-down electric car out of a tight spot, or use the car to store electricity for your home photovoltaic system.
