A hybrid battery system (10, 12) comprises a high power, low impedance battery (20) in parallel with a high energy battery (22), which have substantially equal, fully charged, at rest, terminal voltages. The ampere hour capacity of the high energy battery to a predetermined cutoff voltage is at least twenty times the ampere hour capacity of the high power battery to the same cutoff voltage. The electrical couples of the high power battery and the high energy battery are different one from the other; and may be chosen from the group of pairs of electrical couples consisting of lead acid and nickel zinc, lead acid and lithium ion, lead acid and lithium polymer, nickel zinc and lithium polymer, nickel metal hydride and lithium polymer, and carbon nickel oxide and nickel zinc. If the hybrid battery system is carbon nickel oxide and nickel zinc, then the carbon nickel oxide battery may comprise carbon impregnated into a nickel foam substrate, and the nickel electrode may be a compressed pasted nickel oxide electrode with a thickness in the range of 0.007 to 0.012 inches. |
