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.
