How Boost works
Imagine that you come home from work, and your electric vehicle's battery is at 20% charge. You are going to the cinema later, meaning that you need to charge from now until you have to leave. Instead of going in and changing your charge rule, you can simply click on Boost and your car will immediately start charging .
The car will remain in Boost mode until at least one of the following scenarios occurs:
The car is charged to 100%
The car is charged to the maximum value entered in the charging rule
You disconnect the car
Then it will go back to Smart Charge mode.
