Can I use my electric car battery to power my house?

The ability to use your electric car to power your house (called vehicle to house or V2H) depends on the specific model and feature set of the vehicle. Older electric vehicles does not have that capability, but some of more recent vehicles do have the ability to power electric appliances off of the car battery, but it is rare that the car will be able to power the whole house. Although it is a great feature, it adds additional strain and design constraints on the car battery pack increasing the price of the car. There are some models, which supports vehicle to house, but it is an additional system and it may require additional equipment to be installed in the house to be able to connect the car.
