Abstract
A load is connected to a first battery group. The first battery group and a second battery group are connected in series to each other. A bidirectional DC/DC converter for electric power migration between the first battery group and the second battery group is provided.
Claims
exact text as granted — not AI-modified1 . A battery power circuit comprising:
a first battery group connected to a load; a second battery group connected in series with said first battery group; and a bidirectional DC/DC converter for electric power migration between said first battery group and said second battery group, wherein a charging capacity of said first battery group is different from a charging capacity of said second battery group.
2 . A battery power circuit comprising:
a first battery group connected to a load; a second battery group connected in series with said first battery group; and a bidirectional DC/DC converter for electric power migration between said first battery group and said second battery group wherein, said second battery group is constituted by capacitors.
3 . The battery power circuit according to claim 1 , wherein said first battery group has a higher charging capacity than said second battery group.
4 . The battery power circuit according to claim 2 , wherein a diode is connected in parallel to opposite ends of a group of said capacitors.Join the waitlist — get patent alerts
