EVWire brief: Monta’s latest “EV Chargers Performance Score” for Q1 2025 ranks the Siemens SiCharge CC AC22 as the best-performing AC charger (score 85.21) and the Kempower C-Series as the top DC unit (score 90.85). The quarterly benchmark draws on tens of thousands of live charging sessions logged on their platform, mostly across Europe.

The Monta Performance Score is calculated from three core indicators:

  • Charge Success Rate – the proportion of sessions successfully launched and completed, without interruption or malfunction

  • Uptime Rate – assessment of the time during which a charging station is technically operational and accessible to users.

  • User Satisfaction Rate – feedback, evaluations and comments submitted after each charging session.

Here’s what they found as top AC chargers (see their blog for the whole top 50):
