Your needs and expectations for DC chargers for electric vehicles

We are currently developing an end-to-end eMobility solution for low-power DC solutions, in particular for powers from 25 kW to 35 kW, and 50 kW to 70 kW.

With this questionnaire, we would like to better understand your current challenges and identify your future needs and requirements.

1/1

1. Do you currently use DC chargers from power ratings from 25 kW to 35 kW and/or 50 kW to 70 kW?

Yes

No, but I intend to within the next 6 months

No, but I intend to within the next year

No, and I don’t intend to.

I don't know

1/1

2. What power range can be expected for DC charging stations?

You can select up to 5 items
