What is DC Fast Charger?
"DC" refers to "direct current," the type of power that batteries use. EVs have "onboard chargers" inside the car that convert AC power to DC for the battery. DC fast chargers convert AC power to DC within the charging station and deliver DC power directly to the battery, which is why they charge faster.
Different from most car development projects, the Air model is a model with an overall functional design. Bach mentioned that during the development of the Air model, the researchers under Lucid did not benchmark similar models of other manufacturers, and started formal research and development after listing a list of targets. Lucid's goal is to create a new generation of electric vehicles, so it uses the most advanced computer-aided engineering (CAE) technology and simulates each part.
When researchers develop the powertrain of the Air model, the overall function analysis method is particularly important. Bach mentioned in this regard that the researchers under Lucid will not independently develop any single component. In order to make the entire system have the best performance, each device should meet its best indicators.
Space Concept
Researchers under Lucid used Space Concept to design the Air model, which is an optimized solution that relies on a miniaturized design process.
In recent years, miniaturization technology has been promoted in the field of automobile manufacturing. Researchers under Lucid have miniaturized the entire vehicle system to increase its power density. Bach mentioned that an unnamed luxury sports car has a rear-drive unit, the maximum power produced by it is slightly less than 447 kW, the total mass of the rear-drive unit is about 175 kg, and it has a two-speed gearbox. feature. Compared with this model, the output power of the rear drive unit of the Air model exceeds 447 kW, and the total mass is less than 100 kg. The mass saved can be used to arrange more batteries to extend the vehicle's cruising range. According to the assessment of the U.S. Environmental Protection Agency (EPA), the Air model has a cruising range of 827 km after a single charge.
Bach mentioned in this regard that the power system can output a larger torque in a wide range of working conditions, but this also means that the system must effectively deal with overheating. Researchers under Lucid adopted a self-developed winding pattern to enable Air models to have greater torque under specific speed conditions and to fully cool the high-heat area of the copper coil. The cooling channel in the copper coil is unique, but the current solution for Air models is to ensure that the temperature of the copper coil is low while avoiding excessive current.
All-wheel Drive
Air models with dual motors use all-wheel drive. For any car, four-wheel drive is an important advantage, but compared with a fuel car with a drive axle, electric cars have fewer disadvantages, because in a fuel car, the power from the engine is transmitted to other axles. Usually face a lot of losses in the process.
Fast Charging
Air models have industry-leading cruising range and ultra-fast charging time. Lucid has developed a battery system with superior performance through cooperation with Samsung, LG, Sony Murata and other related companies. The system can optimize the resistance from the battery to the converter to reduce energy loss.
Researchers under Lucid have equipped Air models with an efficient charging method. When the vehicle is running at high speed, the battery becomes very hot, which reduces battery performance. In order to deal with such situations, Lucid's researchers have developed an efficient cooling technology that can keep the temperature of the cells, modules and battery packs in a stable state.
The Air model is developed based on Lucid's Advanced Electric Platform (LEAP). In the future, Lucid will develop more derivative models through this platform. According to related news, Lucid's second model product will be the Gravity sports utility vehicle (SUV), which will also benefit from the platform.
While retaining the characteristics of the Air model's powertrain, the Gravity model will also use more self-developed components, such as the steering mechanism, 12 V grid architecture, controllers, and a fully redundant Ethernet ring. Through this kind of architecture, Lucid's researchers can develop next-generation products faster and more efficiently.
