As part of the ground-breaking research that is underpinning its efforts to develop innovative drive systems for electric vehicles, DG Innovate uses advanced modelling software to simulate heat transfer and the flow of coolant in its motors and associated electronic assemblies. The software, which includes the COMSOL Multiphysics heat transfer module and Ansys Discovery Fluid Analytics, makes it possible for DGI to optimise the geometry of its designs to ensure efficient and reliable cooling even in extreme operating conditions.
Key components of the DGI drive systems, including motor windings and power semiconductors, are fully immersed in insulating oil which circulates continuously to facilitate heat transfer. By working with the simulation software, DGI engineers have been able to refine their designs so that the drives can operate continuously at peak power. This is an important benefit as it allows compact design whilst keeping the temperature of coils and power devices at a lower level, thus helping to maximise operating efficiency. Vehicles using DGI drives, therefore can have greater range for a given battery capacity than vehicles using more conventional drive systems. In many applications, it also means that the drives are smaller and less costly than would otherwise be required.
