# Release Note

## Version 0.5.1 (14/06/2026)

- include HLC_type option *ISO 15118-20 DC*
- With HLC_type *ISO 15118-2 sim* now also a pure simulation model of high level communication without HIL-Connect is available. 
- for all HLC communication now the option *trusted communication* without encryption is available
- it is now possible to define the Ethernet-Port for the high level communication
- overwork modbus communication in the PHIL cinergia components
- option for evaluation of duty cycle of CP-signal is now possible on *CCS-board* (default) or *PWM analyzer* analyzes in HIL-Computer.

## Version 0.5.0 (26/01/2026)

- improve SCADA widgets for ev twin (based on svg)
- including SCADA widget for ISO state messages
- now HLC_type *ISO 15118-2*, *ISO 15118-2 AC* and *ISO 15118-20 DC BPT* are available
- enabling the option *remote HIL* in HIL-interface
- a lot of small improvements

## Version 0.4.1 (25/09/2025)

- fixing several issues
- improve the ev twin visualization based on svg. This can now be parametrized from top level in *ev twin* component in schematic editor.
- adapt software filter for CP input signal, this is important for amplifiers causing lot of noise.
- in *ev twin* component it is now possible to define the HLC, such as 'ISO 15118-2' or 'ISO 15118-20'. Now it is only working for 'ISO 15118-2'
- enabling to link measurement devices to a HIL device and/or a core
- P-HIL for *CINERGIA-EL-AC-PQ-MB* allows now more setting. It can be master with an included voltage source or slave without, It also allows a second connection. 
- enabling setting timeouts for ISO15118 communication in the top level of *ev twin*.
- solve a bug in the 1ph-converter, filter is now adapted according to execution rate

## Version 0.4.0 (13/03/2025)

- adapt library for new typhoon version 2025.1
- include automatic closing of DC relay


## Version 0.3.0 (01/31/2025)

- the tool box is now called *ev 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
- [x] 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 ideas

## 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.
