Charge in 5 minutes and talk for 2 hours. This is an advertising slogan that everyone is familiar with. It refers to the charging speed of a certain brand of mobile phone. But no one expected that Hyundai Group, which has been developing silently in the field of new energy, would quietly apply this monster charging speed to electric vehicles - Hyundai Group's new pure electric platform E-GMP With this ability 2, the E-GMP platform equipped with an 800V fast charging system can replenish 100KM of cruising range in just 5 minutes. According to the average urban driving speed of more than 20kmh, it is enough for you to drive around for more than 4 hours. .
To put it simply, like i-GMP, E-GMP is the cornerstone for Hyundai Group to achieve a leap into electric vehicles in 2021. The Hyundai "IONIQ5" and Kia "CV" written on the schedule will It debuts as the first model of the E-GMP platform. Unlike current electric vehicles that come from internal combustion engine platforms, the E-GMP platform is specifically designed for electric vehicles and allows for a flat floor design. The space occupied by the engine, transmission and fuel tank has been significantly reduced, innovatively improving the utilization of interior space in the car, while breaking the limitations of the traditional structure and creating a new interior and exterior design style for the car.
In the structural design, E-GMP also fully takes into account all-round application fields such as autonomous driving, high-performance EV, and V2G (Vehicle to Grid) that are about to become a reality, and is expected to expand future mobility. exert a positive impact on travel market share. Of course, as a platform born in the new century, the E-GMP platform also has the characteristics of modularity and standardization. It can not only expand the electric vehicle product lineup in the short term according to customer needs, but also reduce the complexity of vehicle production and improve production efficiency. efficiency.
The most eye-catching feature of the E-GMP platform displayed this time should be its excellent fast charging capability. It can replenish 100km of battery life in 5 minutes, charge the battery to 80% in 14 minutes, and have a 600KM cruising range. , which greatly alleviates the traditional pain point of electric vehicles - charging speed. The world's first 400V/800V ultra-high voltage charging system is the key to achieving this impressive indicator, and is also the core highlight of the E-GMP platform.
However, most of the fast charging infrastructure currently on the market are for electric vehicles equipped with 400V charging systems. For electric vehicles currently equipped with 800V high-voltage charging systems, if you want to use these Fast charging infrastructure requires the installation of other components. The great thing about the E-GMP platform is that it breaks through this limitation and is equipped with a multi-functional fast charging system that does not require the installation of other components. It can use ultra-high-speed charging facilities and existing fast charging infrastructure at the same time. As the world's first patented technology applied to the E-GMP platform, this multifunctional fast charging system makes full use of the vehicle's drive motor and inverter to boost the 400V voltage provided by the charging infrastructure to the most suitable voltage for the vehicle system. 800V voltage, thus achieving stable charging compatibility.
For electric vehicles, in addition to working hard on charging speed and battery capacity, it is also very important to know how to reduce losses, and the E-GMP platform plays a role in "throttling". In a new twist, Hyundai Group engineers added a clutch between the traction motor and the output shaft of the E-GMP platform, which can achieve true front/rear/four-wheel drive switching. The motor does not work in the two-wheel drive state. No need to be driven to rotate, thus reducing resistance.
That’s not all. In order to ensure a spacious interior space and reduce the weight of the car body, the PE system of the E-GMP platform reduces the overall volume and weight, reduces the loss of energy transmission between various components, and Performance and efficiency are increased to the maximum, while the motor, reducer, and converter are integrated. In addition, the maximum speed of the motor has been increased by 30 to 70% compared with the past, and the reduction ratio has been increased by 33%. Efficiency has been optimized through the reduction of motor size and lightweight design.
The E-GMP platform also adopts a standardized battery system that is most suitable for special electric vehicle models, which can be flexibly matched according to the model level, driving distance and customer's lifestyle.
All vehicles developed based on the E-GMP platform will be equipped with the same standardized battery module, which is composed of the highest standard energy density battery. Based on this standardized module, users can create basic models and models based on the number of modules installed. Diverse battery pack configuration models such as battery life models.
The inverter power module of the rear wheel motor system uses silicon carbide (SiC) power semiconductors that are more efficient than existing silicon (Si). The system efficiency can be increased by 2~3%. The cruising range can be extended by about 5%, that is, it can travel longer distances with the same number of batteries.
If you open Hyundai Group’s grand plan, you will understand that this Korean giant is really not joking. Among the 44 electrified models that Hyundai Group plans to launch by 2025, electric vehicles*** 23 models, including 11 special models for electric vehicles, accounting for the largest proportion; at the same time, the group plans to achieve an annual sales target of 1 million vehicles in the global market and become a veritable global leader in electric vehicles. From next year to 2024, Hyundai Motor will be the first to launch a product lineup covering three dedicated electric vehicle models: a compact CUV, a mid-size sedan and a large SUV.
Kia, which is also part of the Hyundai Group, is also gradually implementing the medium- and long-term development strategy "Plan? S" and is committed to innovative transformation and upgrading of its mobility and electric vehicle business systems. Kia Motors announced in September this year that it plans to expand the proportion of electric vehicle sales to 20% by 2025, and released a schematic diagram of 7 models. These models include CV and high-performance models that Kia Motors plans to launch by 2027. Special models of electric vehicles within. Koreans have also begun to take action seriously, and new forces in the field of electric vehicles have made their debut with the release of the E-GMP platform.
