Charge Protocol
The Charge protocol is composed of a network of decentralized charging devices that enable electric vehicles and electricity providers to efficiently exchange energy in a secure and trustless manner. The network incorporates blockchain technology to protect user data and verify the transfer of electricity, as well as the location and payment of services.
In addition, the protocol will simplify the overall charging process by streamlining the current payment infrastructure and promoting the utilization of new energy storage solutions. This will reduce the current demand on the electricity grid while incentivizing the participation in a secondary energy economy.

*Please note, the Charge protocol is a continuous project that is constantly changing to better support all who participate. As developments and efficiencies continue to emerge in the industry, the network will incorporate new technologies and thought processes to progress this endeavor. The ultimate goal is to provide real life-value for all participants while accelerating EV adoption.

Key Components:
ISO 15118
​
An international standard that specifies communication between electric vehicles and electric vehicle supply equipment (EVSE). It establishes a protocol for bidirectional energy transfer that can be used to reduce demands on the grid. It is built upon a Public Key Infrastructure (PKI), supporting vehicle identification, authentication, as well as Plug and Charge capabilities.
Open Charge Point Protocol
(OCPP)
An established, open communication protocol for electric vehicle charging stations and network software systems operating charge stations. The protocol is designed to facilitate interoperability between brands and manages charging data. It provides EV charging customers the flexibility to use equipment on any network and decreases the reliance on a single supplier. It also promotes data exchange between electric vehicles and the local grid.
Open Smart Charging Protocol
(OSCP)​
An open protocol that manages the communication between charging software and energy systems. It provides information on the capacity of the grid and forecasts its accessibility over the next 24 hours.
Open Charge Point Interface
(OCPI)
A protocol that facilitates automated roaming across EV charging networks. It ensures EV drivers have access to affordable charging infrastructures owned by different operators outside of their network. OCPI provides data related to charging, location, accessibility, and pricing.
Open Automated Demand Response (OpenADR)
A research development to standardize energy management and create a smarter grid. Its purpose is to reduce the load on the electrical grid by exchanging information and sending signals that help regulate charging devices during periods of high demand.
Decentralized Public Key Infrastructure (DPKI)
An alternative to the Public Key Infrastructure design, a DPKI eliminates the need for a central Certificate Authority (CA) thereby reducing risks associated with centralized control. It is sometimes referred to as a web of trust and the concept establishes a decentralized process for authenticating the relationship between a public and private key.
Charge Protocol
A newly introduced consensus protocol that incorporates the features of the components mentioned above to provide a permissionless encounter that ensures user privacy and accurate power exchange. The concept promotes universal charging access, data privacy, and secure transactions.
Charge Network
A decentralized network of charging devices that streamline services designed to accelerate the adoption of electric vehicles and reduce carbon emissions. The network is composed of multiple devices following the Charge protocol to exchange electricity while providing authentication and data transfer in a private, trustless manner.
Proof-of-Location (PoL)
A digital certificate that verifies the physical location of a device at a specific time. The process utilizes geolocation technology while ensuring user privacy.
Proof of Charge (PoC)
A novel concept introduced by the Charge protocol that verifies a devices location and its ability to provide electricity to users. It allows the blockchain to function across a number of hardware devices operated by a distributed network of independent suppliers. Proof-of-Charge authenticates the accurate exchange of electricity between devices while ensuring user privacy, vehicle privacy, and location privacy.
Proof-of-Stake (PoS)
​
A consensus mechanism that selects validators based on the number of coins, or the amount of stake in the ecosystem. The validator processes the transactions and generates a new block to be added to the blockchain.
Charge (CHRG)
The native currency that powers the Charge Network. It is earned by either providing electricity, validating charging, or transferring user data in a private and secure manner over the network.
