Abstract

Electric vehicles (EVs) include a high-voltage (HV) traction battery and a low-voltage (LV) auxiliary battery. Several EV on-board chargers (OBCs) have the capability for traction-to-auxiliary (T2A) battery charging mode which keeps the LV battery fully charged and available. When the traction HV battery state-of-charge (SOC) falls below a predefined minimum SOC level, the HV traction battery get disengaged. To enhance resilience of EVs under such scenarios, in this paper, a new auxiliary-to-traction (A2T) battery charging mode is proposed in which LV auxiliary battery is used to charge traction HV battery. To facilitate this A2T mode of operation, the bidirectional power-flow is required. The proposed A2T can offer up to 3- 5km extra range to reach nearby charging station or to safety. The proposed system configuration is simulated in the MATLAB/Simulink environment and results are presented showing the system performance.
