The use of an image of a "house" in the logo will be rejected, the "mypowerhouse" organisation is for a place to stop and catch up with emails, maybe grab a coffee and a bite to eat whilst you car is charged.

The use of an image of a house is not compatible with that concept. In the English language a powerhouse meaning is "a thing of great energy, strength, or power" and is what some very successful businesses are referred as.
