When supercharging the battery it is recommended to be preconditioned on the way to the supercharger by simply selecting navigation, and choosing the supercharger planned for charging. Select the charger well in advance 10-20 minutes prior to reaching the Supercharger. This will ensure the battery is ready to receive the higher charge. A complaint by some has been seeing a much lower level when connecting to a supercharger, that was probably caused by not preconditioning. Also, it is necessary to change to different charging unit if a very low charging level is occurring.
