How to Build Your Own High-Performance Charger with EVerest
summary
EVerest provides a module-based embedded Linux stack that implements ISO 15118-2/20 and DIN 70121 vehicle protocols and OCPP 2.0.1 and 1.6 backend links, with modules you can write in C++, Python, JavaScript or Rust and an Apache 2.0 license. Reference hardware includes Yeti and Yak reference boards controlling contactors, meters, isolation monitors and a PLC modem; lab rigs hit ~22 kW and a K2 unit reaches ~70 kW. A micro megawatt backpack tester emulates full session logic over PLC and CP using a USB‑C power bank so communication stacks are testable without delivering real power.
