The rapid growth of electric vehicles (EVs) has increased the demand for efficient and flexible charging solutions. This project presents a Vehicle-to-Vehicle (V2V) wireless charging system that enables one vehicle to transfer electrical energy wirelessly to another vehicle without physical connectors. The proposed system uses inductive power transfer technology, where electrical energy from a donor vehicle’s battery is converted into high-frequency pulses and transmitted through a wireless power transmitting coil.   An Arduino Nano serves as the central control unit, monitoring system battery voltage using voltage sensor. The transmitted wireless power is received by a secondary coil in the receiving vehicle, converted from AC to DC, and regulated using a TP4056 charging module to safely charge a 3.7V Li-ion battery. Continuously monitor the battery voltage on LCD display, while a buzzer provides audible alerts for fault or threshold conditions.   This system eliminates the need for conventional charging cables, reduces wear and tear of connectors, and enhances safety and convenience. The proposed V2V wireless charging model demonstrates a practical solution for emergency charging, roadside assistance, and smart EV ecosystems, contributing toward sustainable and intelligent transportation systems.
