GitHub - mobilityhouse/ocpp: Python implementation of the Open Charge OCPP Python package implementing the JSON version of the Open Charge Point Protocol (OCPP). It is also important to note that simulations dont have to be limited to assumptions. OCPP is an application protocol a language that allows communication between a compliant charge point, like the EVLink range, and any central network system. Smart charging, on the other hand, means that the charging process is directly coordinated and automatically managed by a central system. So you end up with a mixture of different prefixes which can be avoided simply by leaving Charge point identity set to the default of charger. By editing the OCPP server source code, one can avoid these problematic messages and obtain useful charger behaviour. These fees can easily be 50% of the total electric bill and are significant when charging electric vehicles. With just a few steps you can earn rewards for charging in a way that is better for the environment. A tag already exists with the provided branch name. This might seem like a less obvious benefit, but it will be more and more important when companies start mixing slow and fast chargers at locations.
