Plug-in battery charging booster for electric vehicle
First Claim
1. A system for charging an electric storage battery in an electric vehicle comprising:
- a first converter electrically connectable to a first source of AC electric power, for converting AC from the first power source to a first DC output;
a second converter electrically connectable to a second source of AC electric power that is out of phase relative to the first AC power source, for converting AC from the second power source to a second DC output; and
a regulator electrically coupled to the first DC output, the second DC output and the battery, for producing and charging the battery with a third DC output having a higher voltage than the voltage of the first and the second DC outputs.
