Bosch Takes Aim At Zero-Emission Cities With Electrified eCityTruck Powertrain
August 24th, 2018 by Kyle Field
Bosch has taken the wraps off of its new eCityTruck electrification solution for light commercial vehicles that was developed to provide electrification solutions for vehicles operating in urban environments where combustion engines are restricted or banned.
The new powertrain solution is comprised of two new scalable solutions — an eAxle that directly drives the vehicle from an all-in-one electric transaxle configuration, and Bosch’s new electric drive module. The scalability of the new ePowertrain solutions from sub-compact cars all the way up to light commercial vehicles from a long-standing electrical solution provider like Bosch is sure to give small and large automakers another option when considering building electric vehicles.
Bosch’s electric drive module combines the power electronics and the motor into a single enclosure, simplifying installation and engineering while minimizing the cost of materials required if the units were purchased separately.
- High system efficiency: The electric drive module combines components in a single system, which drives overall efficiencies.
- Scalable: The performance of the system can be adapted to different vehicle types and payloads. The electric drive module is available in various configurations up to 180 kW of power and 540 Nm of torque.
- Compact design: Combining the electric motor and power electronics in a single powertrain unit saves space and money.
The eAxle was designed to leverage the increased efficiencies of combining the transmission, electric motor, and electronics into a single housing. The compact, scalable design makes it suitable for fully electric or hybrid electric vehicles ranging from sub-compacts to sport cars up to light commercial vehicle applications.
- High system efficiency enables either increased electric range or smaller battery size, further improving vehicle efficiency.
- Cost-effective: combining power electronics, the electric motor and transmission into a single unit, the cost of the eAxle is lower than purchasing and integrating individual components.
- Scalable: The scalability of the solution from 50-300 kW allows it to be used in a wider range of applications and vehicle types. Torque output for the various integrated motors ranges from 1,000 to 6,000 Nm.
- Maximum speed of the electric motor: 16000 1/min
Eliminating or drastically reducing urban emissions is one of the key challenges for cities in the next 5 years as many push hard to clean up their transportation emissions with an all-out ban of combustion vehicles or restrictions on designated zones in the city for combustion vehicles. These two new scalable solutions from Bosch give vehicle builders and delivery companies a few more options when considering the path forward for the electrification of their fleets.
