Distributed Intelligent Vehicle to Vehicle Charging Relay Network (DIVVCRN) is a modular electric vehicle charging infrastructure concept designed to reduce the cost, complexity and spatial limitations of conventional EV charging systems. Instead of requiring a dedicated charging station for every parked vehicle, the system enables multiple electric vehicles parked sequentially along roadsides or parking lanes to share power from a single grid connected charging source through intelligent front and rear vehicle couplers. Each vehicle acts as both a charging node and energy relay point creating a controlled charging chain capable of dynamically distributing electrical power between connected vehicles.

The system operates using integrated front and rear conductive couplers mounted on each vehicle. The front coupler receives regulated high voltage DC power from the preceding vehicle or charging station while the rear coupler transmits controlled power to the next vehicle in the chain. Unlike simple pass through electrical systems each vehicle contains an Intelligent Power Distribution Module (IPDM) consisting of isolated DC to DC converters, thermal monitoring sensors, smart contactors, fault isolation circuitry and communication controllers. This architecture prevents direct battery to battery current transfer and instead regulates downstream power safely through controlled conversion and current limiting.

Major innovation of the design is its dynamic load balancing capability. The network continuously monitors battery state of charge, connector temperature, cable current and downstream demand allowing charging power to be automatically distributed according to vehicle requirements and infrastructure limits. By operating on high voltage DC bus architecture, the system significantly reduces current accumulation, cable heating, connector wear and conductor size requirements. Integrated thermal sensors and adaptive current control further minimize overheating and fire risks.

The coupler itself serves multiple functions beyond electrical transfer acting as mechanical spacing buffer between vehicles, maintaining safe parking distance, airflow clearance and maneuvering space for vehicle exit. The charging chain is designed as hot swappable network allowing vehicle to safely disconnect and leave without disabling entire charging sequence. When vehicle exits, intelligent isolation contactors temporarily pause downstream charging, electrically isolate the coupler and automatically restore charging once the next vehicle reconnects.

Safety is central component of the system. The design incorporates arc detection, ground fault interruption, waterproof locking connectors, automatic shutdown protocols, thermal overload protection and fault isolated modular power routing. Each vehicle independently isolates faults preventing cascading electrical failures across charging chain. Use of flame resistant materials, touch safe connectors and communication based authentication further enhances operational safety and theft prevention.

This system is manufactured using existing EV charging technologies, high voltage connectors, DC power electronics and automotive communication systems such as CAN bus or Power Line Communication (PLC) making implementation technically feasible without requiring entirely new infrastructure standards. Potential applications include dense urban roadside parking, apartment complexes, commercial fleets, taxi stations, public parking corridors and developing regions where charging infrastructure deployment costs remain prohibitive.

DIVVCRN represents significant advancement over conventional one station per vehicle charging systems by introducing scalable, infrastructure efficient and intelligent distributed charging capable of supporting broader EV adoption at lower deployment cost.
