CCS combines the advantages of existing charging systems into one single solution that can handle any charging scenario. To help develop this standard, CharIN has five expert groups, divided as followed:
![Charging Infrastructure](https://www.charin.global/media/pages/home/focus-groups/20caa3518d-1615552456/charin-fg-charginginfrastructure-320x320-crop-true-q95.png)
Charging Infrastructure
- Harmonization of the ramp-up of CCS charging infrastructure and the involved charging process based on the market needs: removing market entry barriers for EV owners, charge point operators and manufacturers
- Product Lifecycle Management perspective on CCS
