This guide uses approximate data. Charging speeds, prices, and compatibility depend on your specific vehicle variant, station hardware, and conditions. EVcourse is not affiliated with Mercedes-Benz or Helen. Always check your vehicle manual and the charger screen.
Quick Overview
Step by Step
Find a Helen station
Open the Helen app or use a charging map like PlugShare to find a nearby station. Before you drive there, check that the station has an available CCS2 connector and is currently working.
Start your session
Open the Helen app, select the charger, and start the session. You can also use an RFID card.
Plug in the CCS2 connector
Take the CCS2 cable from the charger and connect it to your Mercedes-Benz EQS SUV's charging port. You should hear a click when the connector locks in. Your car's display will confirm the connection.
Charging starts
Once connected, your Mercedes-Benz EQS SUV can pull up to 200 kW. On Helen chargers (up to 200 kW), your effective maximum is 200 kW. You will see the current power and estimated time on either the charger screen or your car's display.
Charging speed is fastest when your battery is between 10% and 50%. It gradually slows as the battery fills up. This is normal and protects battery health.
When to unplug
For the fastest experience, unplug at 80%. Charging from 80% to 100% takes almost as long as 10% to 80% on most EVs, including the Mercedes-Benz EQS SUV. On a road trip, stopping at 80% and driving to the next charger is usually faster than waiting for 100%. Check your vehicle's manual for charge limit recommendations.
Charging Speed on Helen
Your Mercedes-Benz EQS SUV peaks at 200 kW DC. Helen chargers deliver up to 200 kW, which matches your car's capability.
Charging from 10% to 80% takes about 31 minutes under good conditions.
Actual speed depends on several factors: battery temperature (cold batteries charge slower), your current state of charge (charging slows above 50-60%), and how many other cars are sharing the same station. If other cars are plugged in at the same location, the charger may split power between them.

Tips for Charging Mercedes-Benz EQS SUV on Helen
