If you have an Opel Ampera-e, then you use the CCS plug. Please ensure that you insert the plug properly.
The charge speed is up to 50 kW. The actual charge speed depends on the state of charge of the battery when plugging in. On average the Ampera-e charges from 30% to 80% in 35 minutes. Above 90% the charge speed will slowly drop.
In some cases the car does not release the connector. On the cars remote control you can press an 'unlock' button, hold this button for some seconds. This way your car will release the connector.
