A new blockchain-based framework brings EV charging on the go, optimizing efficiency, availability and cost control for remote and infrastructure-limited areas听
听
As electric vehicle ownership increases, so does the demand for reliable charging infrastructure. A Khalifa University research team has developed a new framework called BlockCharge: an innovative solution combining mobile charging stations (MCS) with blockchain-based auctions to streamline EV charging.听听

Dr. Zainab Husain, Dr. Tarek El-Fouly, Dr. Shakti Singh, Dr. Rabeb Mizouni, Prof. Hadi Otrok and Prof. Ehab El-Saadany developed the framework to address some of the key challenges that EV drivers face and aim to transform the EV charging landscape. Their solution not only provides more flexible charging options but also introduces fairness and transparency through blockchain technology. The team published their work in , a top 1% journal.听听

鈥淥ne of the biggest barriers to widespread EV adoption is the lack of sufficient charging stations, particularly outside urban centers,鈥� Prof. El-Saadany explained. 鈥淗owever, while charging stations abound in urban centers, building traditional charging stations in remote or sparsely populated areas is costly and logistically complex. Mobile charging stations have emerged as a promising alternative, allowing charging services to travel to where they鈥檙e needed, rather than requiring drivers to locate a fixed station. But with this flexibility comes a new set of challenges: how can these mobile stations be efficiently allocated to meet demand, how can pricing be kept fair and transparent, and how can service quality be ensured?鈥澨�

The team developed BlockCharge as the solution to these questions, combining blockchain technology with a novel auction system. The blockchain鈥攁 decentralized, secure digital ledger鈥攅nsures that every transaction in the system is transparent and tamper-proof. By building the entire MCS allocation and charging transaction system on a blockchain, BlockCharge can facilitate secure transactions and build trust between service providers and EV owners. The system is based on smart contracts: automated agreements that execute certain actions once specific conditions are met. These smart contracts handle the auctioning, allocation, and payment processes for EV charging, minimizing the need for intermediaries.听听

鈥淭he process is simple,鈥� Prof. El-Saadany explained. 鈥淲hen EV drivers need a charge, they submit a request to the local aggregator for their zone, including details such as their current location, battery status, and the energy needed to reach their next destination. The system takes care of the rest, automatically matching the request to a nearby MCS. Payments are handled by the听 blockchain-based smart contracts, ensuring a secure transaction where funds are only released once the charging is complete. The MCS operators, for their part, benefit from a streamlined system that lets them plan their routes and bid for charging requests based on real-time data from their surrounding zones. The auction system keeps all operators on an even playing field, encouraging efficiency and fair competition.鈥澨�

A critical feature of BlockCharge is that it mitigates the risk of price inflation鈥攁 common issue in areas where demand for EV charging outstrips supply. When multiple MCS operators bid for charging requests in an open auction, it creates a competitive environment that naturally keeps prices more reasonable. Furthermore, the blockchain ledger records all bids, allocations, and payments, allowing any participant to verify that they were treated fairly. The transparent nature of blockchain helps ensure all transactions are secure, immutable, and free from manipulation by any single party.听

BlockCharge鈥檚 decentralized, blockchain-based approach could transform the EV charging market as it scales up to larger areas and integrates with existing infrastructure. This could enable a future where both fixed charging stations and MCS are seamlessly coordinated to meet demand in a variety of settings, from dense urban neighborhoods to rural highways. By adding the flexibility of mobile units to areas without sufficient fixed infrastructure, this hybrid system could help make EVs a viable choice for even more drivers.听
