Abstract
In electric vehicle (EV) architectures, a significant risk to electromagnetic self-compatibility is crosstalk between high voltage (HV) cables and low voltage (LV) signal lines such as the Controller Area Network (CAN) bus. Switching noise resulting from inverter or DC/DC conversion operations can be carried on HV lines and then couple into sensitive LV lines via a radiative crosstalk mechanism. When these threats are identified in advance, computational electromagnetic (CEM) modeling and simulation can be used to rapidly iterate through different design mitigations to arrive at a practical and cost-effective solution to ensure self-compatibility between the HV and LV systems. This paper presents a case study where this approach was used to improve the design of an EV mobile charging trailer to prevent likely threats to the CAN network.Keywords
