Defining three operation modes including charging, discharging and idle, the proposed converter guarantees multiple outputs isolated from EV-high voltage battery (EV-HVB) with significant safe operation regardless of the power flow direction between the auxiliary battery and EV battery cell. Compared to the existing APMs, the proposed PV-integrated APM provides much wider voltage ranges for internal loads based on low voltage auxiliary battery (LVAB) with a smaller voltage rate and size. Using pole placement method (PPM) as well as comprehensive large-signal and small-signal dynamic models, two closed-loop control systems are presented to enable the desirable current flow and regulated output voltages. To this end, the controllability of the proposed system is extensively assessed, and the effective state feedback gains are designed associated with the closed-loop system eigenvalues with the adjusted and sufficient stability margin. Both simulation and experimental results are employed to verify the noticeable contribution of proposed system along with the designed control technique to APM and BMS in EV applications.  \nIndex Terms— Auxiliary power module, battery management system, PV integration, hybrid DC-DC converter, electric vehicle, high voltage battery cell.  \nI. INTRODUCTION  \nAvery well-designed APM system is considered as a  \nsignificant advantage of EVs for reaching the functional features such as high efficiency, safety and reliability, integration capability, compact design, modularity and scalability. In this regard, researchers and industries have attempted to design appropriate APM systems through meeting the features mentioned above. To this end, some works focused on interfaced-power electronic converters (PECs) between EV-HVB and LVAB [1], by designing active filter auxiliary power module [2], all-in-one magnetic integrated structure of phase-shift full-bridge current doubler converter (PSFB-CDC) [3], and high-frequency high power  \n([Corresponding author: mmehrasa@uno.edu](Corresponding author: mmehrasa@uno.edu)).  \nMajid Mehrasa is with the Department of Electrical and Computer Engineering, The University of New Orleans (UNO), 2000 Lakeshore Dr, New Orleans, LA, 70148, USA ([e-mail: mmehrasa@uno.edu](e-mail: mmehrasa@uno.edu)).  \nNaser Vosoughi Kurdkandi and Chunting Chris Mi are with the Department of Electrical and Computer Engineering, San Diego State University (SDSU), San Diego, CA 92182 USA (e-mail: [nvosoughikurdkandi@sdsu.edu](nvosoughikurdkandi@sdsu.edu), [cmi@sdsu.edu](cmi@sdsu.edu)).  \ndensity PSFB-CDC [4]. Using active power decoupling (APD) technique and full-bridge single-phase dual active bridge (FBSP-DAB) converter with soft switching capability, the charging configuration of the auxiliary battery in the EV driving charging mode was made in [5] . In [6], to eliminate the low-frequency harmonic currents in the high-voltage battery (HVB) charger when the HVB is charging, the LVABand EV-HVB were connected to each other using integrated active filter APM converter based on dual-voltage charging systems.
