Every auto show, real technology, not necessarily in the booth of the vehicle manufacturer. Because the current business model of the automotive industry is still the main way to integrate all parties. So the technical supplier’s booth is often the most look. At this Munich car show, EF demonstrated the latest modular electric drive components and the most trip-“PROAI” (PROAI).
Modular electric drive component assistance enterprise development time is reduced
The modular electric drive assembly is mentioned. Coifer has always been in the field of gearboxes, in the field of industry, in the field of pure electric drive, will be a core unit of all facilities such as a collection motor, electric control, and reducer. So the importance of this unit is even better than the gearbox itself. However, the electric drive unit, which is very different from the power assembly of the fuel vehicle. On the one hand, the weight will be greatly reduced, and the two, and the plurality of functional units can be highly integrated.
This Qifu’s first modular electric drive assembly on the auto show will collect system solutions, components, and software controls in a flexible. Platform. All modular electric drive components can bring significant increase in energy density, weight, and efficiency. Optimized gear drive modules, add efficient cooling and lubrication schemes to ensure that mechanical loss is reduced by up to 70%.
The maximum advantage of this modularization is to shorten the development time. “In all key values of the EF module-powered drive components, the most important thing for us is 50%. Through the development of the technical foundation and the cross-platform cross-platform development and synergies, we can put the new The development time of the electric drive unit shortens 50%. It has a relatively high technical maturity from the beginning. “Zhu Fu CEO Schiede said. 
Furthermore, the assembly can be flexibly applied to different types of models, from 75 to 400 kW power and electric drive systems of 350 to 540 Nm torque. And you can bring maximum power and energy efficiency by designing the vehicle.The component can be equipped with any model, from the high-end model of the 800 volts of the 800-volt-converter that is equipped with a compact car of 100 kW power and 400 volt transitions, to 200 kW power and a silicon carbide (SiC) technology, regardless of the vehicle enterprise The center of gravity is cost-effective or technical leadership, and the EF module-powered drive assembly can meet these needs and provide maximum flexibility. Due to system design, architecture, software, motor concepts, cooling systems, and some components are developed on a cross-platform, the component can achieve synergistic effects from the beginning of development and have higher technical maturity. The core content of the component is based on the mature production technology of Effu, which can quickly respond to the specific needs of the customer to supplement or adjust.
Specifically, this modular electric drive assembly includes three power levels, as well as “high-order level” (800 volts SiC) and “basic level” (400 volts) two subdivision schemes. The three electric drive systems included in the “Modular Electric Drive Suite” are about to step into the output stage, including “primary” drivers within 100 kW, “intermediate” driver within 200 kW, both based on ASM (permanent magnet) Asynchronous motor) or PSM (permanent magnet synchronous motor) motor and 400 volts inverter technology; there is also an output power of more than 200 kW, which will enter mass production in the second half of 2022, With a PSM motor (permanent magnet synchronous motor) and a 800 volt inverter based on silicon carbide (SiC) technology.
In order to meet the four-wheel drive scheme, Qifu announced a set of Econnect modules on the basis of the modular electric drive assembly. Econnect is a flexible four-wheel drive system solution that does not affect the overall arrangement space, allows the auxiliary driver to take the initiative to take the initiative to take the initiative to decrease up to 90% mechanical drag loss. But when there is a need, Econnect can respond quickly within a few milliseconds, and start the second drive through the claw coupling, and there is no energy loss. Compared with the best homologous system on the market, the efficiency of the Econnect four-drive system has increased by 2%.
In addition, in the software level, Qifu launched a set of intelligent predictive cruise control systems (Accnext) with the electric drive module. When the software is opened, driveSeamlessly connect between the dynamic system and the regenerative brake system. Intelligent prediction cruise control system (Accnext) incorporates factors such as traffic flow, traffic signals and terrain conditions into comprehensive considerations. According to the software itself, AccNext can save up to 13% energy sources by using the software itself predicts the use of infrastructure.
A new generation of “Curi Star” (ProAi) increased by 66%
The core of the vehicle is in the central operation unit, because whether it is automatic or intelligent The function of the cockpit requires power to be comparable to the supercomputer. To this end, EF brought the latest generation of “Core Stars” in this auto show, which is the first appearance in Europe. Previously, this new generation of computing units were started in April this year. It is currently in the market, which is more flexible for the automotive industry, powerful in-vehicle computer.
Coof “Curi Star” has a 20 teraops to 1,000 teraops Extended performance level. Compared with previous versions, the latest generation “Core Star” performance increased up to 66%, and enable energy consumption reduced by 70%, and finally achieved the average energy efficiency of 3 TERAOPS per watt. At the same time, all of the different versions of the “Core Star” of EF “are installed on standard housings of 24 x 14 x 5cm. This means that the area it occupies is smaller than the iPad. CF “Co-Star” will apply to various types of vehicles and supports automatic driving applications at each level of L2 to L5.
