You can easily calculate how long it takes to charge your electric car. The battery of an electric car always has a certain capacity, expressed in kWh. For example, if the battery has a capacity of 74kWh and the charging station delivers a power of 7,4kW, it will take 10 hours (74/7.4 = 10) to fully charge the completely discharged battery. If you do have to charge while on the road, you can often use a fast charger. You can fill a large part of the battery in a short time so you are quickly back on the road.
