eAxle by Bosch: A revolutionary electric drive solution
The Bosch eAxle is a compact, modular, cost-effective and efficient drive system. The electric vehicles will benefit from Bosch eAxle. The modular nature of the system opens up the immense potential to the electric vehicle industry. The battery-electric vehicles and hybrid solutions will benefit the most.
Furthermore, the Bosch eAxle is a combination of the electric motor, power electronics, and transmission. All of these three are combined into a single unit directly powering the vehicles Axle. Hence, it makes the drive train simpler instead of complex. In addition, the powertrain becomes compact, cheap to manufacture and highly efficient.
In addition, the compact nature of the module increases space savings. So, you will get more space for your luggage or you will have more legroom and so on. Space is the most important factor in vehicle design and eAxle fits in for the same.
The higher system efficiency delivers more electric range and reduces the need for higher battery capacity. The immense scalability of the eAxle allows its use in various applications. eAxle reduces the cost significantly as it removes the need for various components in the drivetrain. In addition, it reduces the cost of highly expensive connecting cables.
Bosch eAxle adaptability
The modular nature of eAxle has immense adaptability. It can fit into a modern sports car and light delivery vehicles at the same time. Thanks to its power output, the construction of the eAxle is variable as power output can scale from 50 to 300 kilowatts.
Furthermore, eAxle’s flexible manufacturing process and modular construction bring more versatility in its use. You can simply customize power output, torque and possible installation space. So, you can fit Bosch eAxle in SUVs, sports cars, passenger cars, and light commercial vehicles.
In addition, the high efficiency of the eAxle is due to continuous development in electric motors and power electronics. Bosch has specifically reduced the number of interfering components like power cables, cooling components and connectors in order to improve efficiency. Higher efficiency means more electric range with less battery capacity.
The efficiency of the Bosch eAxle is high. The power electronics convert direct current coming from the battery into the alternate current as electric motor requires alternate current. Hence, power electronics converts electrical energy into mechanical energy.
Furthermore, the electric motor transmits torque to the transmission. The transmission adjusts the speed of the electric motor in tune with the driveshaft. The transmission also simultaneously amplifies the motor’s torque. So, the combined efficiency of power electronics, electric motor, and transmission add up to the overall efficiency of eAxle. Optimizing and integrating these components further enhance efficiency.
Bosch eAxle specification
The eAxle has a scalable power output that ranges from 50-300 kW. Similarly, it has scalable torque that ranges from 1000-6000 Nm. The maximum speed of the electric motor is 16000 1 per minute. The weight of the motor that produces 150 kW of power is 90kg.
The eAxle has high system efficiency and hence more electric range in less battery capacity. The high scalability increases its use in a range of applications for various types of vehicles. The product is highly cost-effective as it cuts the cost of expensive cables and other components. The flexible manufacture process enhances its utility to the next level.
