Protocol emulation / IoT
EvCharger Emulator
An emulator for electric vehicle charging stations speaking the industry standard protocol, for testing management systems without physical hardware.
The problem
Developing against real chargers is slow and expensive, and the error cases — an interrupted session, a charger that stops responding — are hard to trigger on demand. The emulator turns them into a configuration setting.
Emulating a protocol forces you to read it more carefully than implementing one side of it: you also have to understand what the other end expects to receive when something goes wrong.
