ZF is presenting its portfolio of modular electrification solutions at the IAA 2021.
A current volume order for the Group covers both low-emission, partially electrified and purely electric driveline technology.
The Modular eDrive Kit serves increasing global demand for purely electrically driven vehicles and enables ZF to reduce the development time for new e-drives by up to 50%.
The eConnect solution, which is ready for series production, also saves energy and enables optional all-wheel drive. The start of series production of three new e-drives is planned by autumn, 2022.
The supplier maintains the Group has already developed sustainable mobility solutions for series production or in series production readiness. In the electrification of the passenger car driveline, ZF supports the automotive industry with solutions that match different speeds of international markets.
For example, a current volume order worth several billion Euros covers the supply of conventional, but primarily mild and plug-in hybrid variants of the fourth-generation 8-speed transmission (8HP). In addition, key components for pure electric drives such as power electronics and e-motors are also part of the scope of supply.
The highlight for ZF at IAA 2021 is the Modular eDrive Kit for purely electric drives. This bundles the experience of ZF’s e-mobility team for system solutions, components and software controls in a modular platform.
An advantage of the modular approach is shorter development times: “With our Modular eDrive Kit, we will achieve a halving of development time to series production readiness,” said ZF board member and head of ZF Car Driveline Technology Division, Stephan von Schuckmann.
In addition, the Modular eDrive Kit is suitable for different vehicle segments: Configurations with e-machines from 75 to 400 kW drives and from 350 to 540 Nm torque are possible and can be designed for performance and efficiency.
Examples are: compact cars with 100 kW drives and 400 V inverters to premium segment, 200 kW and 800 V inverters based on silicon carbide, offering flexibility; depending on whether the focus is on cost efficiency or technology.
As the system design, construction, software, electric motor concept, cooling and a number of components are developed on a cross-platform basis, synergy effects and a higher degree of maturity are achieved from the outset. The basic package is based on ZF series technology and can be quickly supplemented or adjusted depending on specific customer requirements.
The Modular eDrive Kit comprises three power classes as well as the Premium (800V SiC) and Basic (400V) segments. Three e-drives comprising the Modular eDrive Kit are about to enter series production: a Low drive solution below 100 kW, a Mid drive solution up to 200 kW – both based on ASM or PSM motors and an inverter with 400-volt technology – and a High solution with an output of more than 200 kW, which will enter series production in the second half of 2022 and combines a PSM machine with a silicon carbide-based inverter with 800-volt technology.
“All new drives bring significant improvements in power density, weight and efficiency,” added R&D Electrified Powertrain Technology SVP, Otmar Scharrer.
