Summary: This paper proposes a bidirectional AC-to-DC buck rectifier topology that can operate in both single- and three-phase versions, enabling grid-to-vehicle and vehicle-to-grid operations. The topology utilizes the switched capacitors principle to achieve self-balancing of voltages in the capacitors and is highly modular in structure. A hardware prototype model is used to validate the proposed power converter and control approach.

Summary: Vehicle to vehicle (V2V) energy sharing is proposed as an alternate solution to address the range anxiety and limited charging infrastructure challenges of electric vehicles (EVs). This article presents a new V2V interface that directly connects the motor winding neutrals and negative rails of on-board drivetrains to form an integrated bidirectional dc-dc converter, allowing control of power flow direction. The proposed approach eliminates the need for reconfiguration of motor winding or drivetrain connections. A scaled lab prototype is developed to demonstrate the energy sharing between two lithium-ion battery banks through this direct V2V power transfer concept.
