Charging time for a BMW i8 Roadster
The table below shows the estimated time to charge your BMW i8 Roadster from empty to full. For rapid charging we show the time to charge from 20% - 80%, as charging tends to slow outside this range to protect the battery.

|3-pin plug||Home||4 h||5 m/h|
|3.7kW||Home / Work||3 h||9 m/h|
|7kW||Home / Work / Public Locations||3 h||9 m/h|
|22kW||Work / Public Locations||3 h||9 m/h|
* Based on Pod Point estimates, charging rates can differ based on the ambient temperature, the state of the battery (e.g. empty or half full) and variation in charging rate.
** Range per hour is the number of miles you can expect to get from an hour of charging at the relevant rate.

*This metric estimates the environmental impact of driving your electric vehicle based on how the electricity that powers your car is generated. We take the average carbon intensity across the UK grid measured throughout 2018 to calculate the expected grams of CO2 emitted per 1 km driven. The actual number will vary by region, when you charge (e.g. carbon intensity is usually lower overnight period) and whether your electricity comes from more renewable sources than the average.
