The Open Charge Point Protocol (OCPP) is the open standard, introduced in 2009 by the Open Charge Alliance, that lets EV charging stations and central management systems (CSMS) communicate regardless of manufacturer. It uses an asynchronous request/response model over WebSocket, supports smart charging and offline operation, and is today the de facto standard in Europe and North America, with OCPP 1.6 the most widely deployed version and 2.0.1 the latest.

Electric vehicles offer zero tailpipe emissions, more energy-efficient motors, lower fuel and maintenance costs, less dependence on fossil fuels and regenerative braking. Their main drawbacks are a shorter driving range, limited charging infrastructure in some areas, longer charging times, higher upfront costs and battery degradation over time.

The main alternatives to fossil fuels are electric vehicles, biofuels and hydrogen fuel cells, each needing its own infrastructure and technology to spread. Petroleum, coal and natural gas remain widely used, and their impact can be reduced with fuel efficiency standards, hybrid vehicles, carbon capture and storage, renewable natural gas and a shift to clean energy.
