ISCAD — Design, control and car integration of a 48 volt high performance drive

Through its new technology the ISCAD system provides up to 300 kW with a safe-to-touch 48 Volt battery. This results in a high-performance drive that is intrinsically electrically safe. The novel machine design requires new concepts for power electronics, control systems, and integration strategies. Further degrees of freedom yield to challenges and even more important to possibilities for all kinds of applications. The innovation of the design will be explained and adjustments for power electronics and control will be worked out. The focus of this paper is the 3 rd generation of Intelligent Stator Cage Drive (ISCAD) prototypes. This first integrated and compact prototype has been used to re-equip a Geely Emgrand EV. The entire system and the mentioned process are described in detail. In addition, the in-house designed 48 V battery is highlighted. Simulations and measurements give an overall demonstration of the potential and the current status of the drive.
