Charging elements and energetic flow of the test bench setup

Typical Use Cases and Car Communication
The difference in demonstration sites within BiFlex-Industrie research project
DC bidirectional with ISO 15118-20 as standardized charging communication protocol for EV and EVSE

Software Tools
Smartphone charging App
Nymea IoT Demo Server (it is for Linux)
Software Interfaces
LF Energy EVerest Framework for car charging
Implementation concepts of home automation and control architecture
Why extensibility matters
Separation of concerns. Advantages of ripe special domain tools against locked systems and cloud-based approaches.

Hardware Concept
Test bench DC-Charger with EVerest
Car simulation with chargebytes Charge Control L
Enabled ISO 15118-20 protocols with TLS
Optional mobile phone App as remote control and UI

Demonstration
Automated charging strategy creation
Forecasting and environmental condition parameters influence charging

Conclusion
Making use of volatile renewable energy by charging and discharging electric cars is valuable, publicly available and technically prepared
