Release Note

Version 0.3.0 (01/31/2025)

  • the tool box is now called ev smart charging twin
  • update documentation
  • improve temperature check of CCS pins. If any temperature out of range power flow ist interrupted.
  • Improve current control. Maximum possible set point for current is defined by BMS.
  • many small improvements and bugs solved

Version 0.2.0 (12/17/2024)

  • remove failure from SCADA widget ev twin
  • include example EVSE
  • adapt functionality to typhoon HIL-Connect EV with sub systems measurement, P-HIL-Interface*

Version 0.1.0 (07/03/2024)

  • examples for AC and DC charging are updated
  • include 1 phase converter enabling asymmetric charging

Version 0.0.1 (01/15/2024)

  • Toolbox ev twin first set up
  • ev_twin.tlib and ev_twin.wtlib
  • schematics library ev twin with the sub systems: ev twin, CCS, EVCC and Power Unit (including some sub models)
  • Power Unit is fully prepared for AC and DC as well as bidirectional charging. In AC mode only symmetric currents are possible
  • DC charging with ISO15118-2
  • ev twin and EVCC have corresponding scada library elements
  • PHIL-setup with modbus for the AC charging with cinergia
  • examples for AC charging
  • ev twin ac: General behavior for AC charging

Features and Ideas for future versions

  • [ ] integrate bi-directional charging (ISO 15118-20) for AC and DC
  • [ ] improve single phase converter model and make it robust
  • [ ] including inverter losses
  • [ ] battery temperature model and battery condition
  • [ ] modbus clients for various charging stations
  • [ ] more EV brands
  • [ ] test scripts for duty cycle charging (IEC 61851-2) --> EVSE test
  • [ ] many more idea

Known issues

  • [] in typhoon version <= 2024.4 on HIL604 the HIL-Connect EV ha got a CAN issue. The sub system fix CAN from ev twin library is needed.
