Abstract

A charging system for a rechargeable battery with a rapid charge capacity. This invention relates to the charging system for the rechargeable battery with a rapid charge capacity which can be recharged at a public place. The charging system comprises a charging equipment for the rapid charge battery, a measurement display unit which measures and displays a charging condition and deterioration of the rapid charge battery, and a fee collection device which collects a charging fee.

Claims

1. A charging system for a rapid charge battery, comprising:

a charging equipment for said rapid charge battery;

a measurement display unit which measures deterioration and charging level of said rapid charge battery; and

a fee collection device which collects a battery charging fee.

4. The charging system for the rapid charge battery of claim 1, wherein

the rapid charge battery is a nonaqueous electrolyte secondary battery, which comprises positive and negative electrodes having materials that occlude and release a lithium ion and containing nonaqueous electrolyte having lithium salt and organic solvent.

6. The charging system for the rapid charge battery of claim 4, wherein

if a charging current flows in the rapid charge battery after completing the charging reaction, the rapid charge battery causes migration of electrons only and functions to prevent said electrode active material from transformation.

8. The charging system for the rapid charge battery of claim 6, wherein

the rapid charge battery is said nonaqueous electrolyte secondary battery which involves the electrolyte with a material subject to oxidation at the positive electrode and causes an oxidation reaction different from the lithium release reaction at the positive electrode while causing a reduction reaction different from said lithium occlusion reaction at the negative electrode.

3. The charging system for the rapid charge battery of claim 2, wherein

said charging information center has a control unit monitoring and controlling the deterioration of the rapid charge battery;

and

said control unit notifies the user via said charging processor when the deterioration of the rapid charge battery goes below a predetermined level.

5. The charging system for the rapid charge battery of claim 2, wherein

the rapid charge battery is a nonaqueous electrolyte secondary battery, which comprises positive and negative electrodes having materials that occlude and release a lithium ion and containing nonaqueous electrolyte having lithium salt and organic solvent.

7. The charging system for the rapid charge battery of claim 5, wherein

if a charging current flows in the rapid charge battery after completing the charging reaction, the rapid charge battery causes migration of electrons only and functions to prevent electrode active material from transformation.

9. The charging system for the rapid charge battery of claim 7, wherein

the rapid charge battery is said nonaqueous electrolyte secondary battery which involves the electrolyte with a material subject to oxidation at the positive electrode and causes an oxidation reaction different from said lithium release reaction at the positive electrode while causing a reduction reaction different from said lithium occlusion reaction at the negative electrode.
