Description

technical field [0001] The invention relates to a simulation model, in particular to a novel electric vehicle simulation model architecture. Background technique [0002] Electric vehicles are becoming one of the most promising technologies in the automotive industry, addressing various environmental and energy challenges. The wiring harness of electric vehicles needs to transmit high-voltage and high-current alternating current, which brings new challenges to the design of high-voltage wiring harness. For example, an AC propulsion motor is an inductive load that is dynamic and its peak current can be much higher than its rms value. Today, many engineers simply use peak current as the limit for calculating wire gauge specifications. This would obviously result in a very conservative design requiring more material and higher price, since the duration of the peak power pulse in a typical drive cycle may be short, perhaps less than 2 seconds. Thermal energy is determined by ...

This would obviously result in a very conservative design and would require more material and a higher price due to the fact that the duration of the peak power pulse in a typical drive cycle may be short, perhaps less than 2 seconds

However, to date there are no proper tools to aid in the design of high voltage wiring harnesses
