| 20120015221 | BATTERY PACK - Provided is a battery pack comprising a plurality of batteries; and a plurality of memories that correspond respectively to the batteries and that each record deterioration information of the corresponding battery. Each set of a battery and a corresponding memory may be formed integrally as a battery cell. As a result, the deterioration information of each battery cell can be known even after the battery pack is disassembled. | 01-19-2012 |
| 20120013304 | BATTERY CONTROL APPARATUS, VEHICLE, AND BATTERY CONTROL METHOD - A battery control apparatus includes: a battery circuit in which a plurality of batteries are connected in series; a plurality of bypass circuits, each of which removes a corresponding battery from the battery circuit; a plurality of switches, each of which switches whether to connect a corresponding battery in series with the other batteries, or to connect the corresponding battery to a corresponding bypass circuit to remove the corresponding battery from the battery circuit; a deterioration detecting section that detects deterioration of each of the plurality of batteries; and a switch control section that controls the plurality of switches to remove, from the battery circuit, the batteries having greater deterioration and connects, in series, the batteries having smaller deterioration. | 01-19-2012 |
| 20120013179 | MANUFACTURING METHOD AND VEHICLE - A manufacturing method of a vehicle, includes: preparing a chassis of the vehicle in which a plurality of battery modules are installed; forming a wiring section in a body of the vehicle; and electrically connecting the plurality of battery modules by means of the wiring section, by coupling the chassis to the body. | 01-19-2012 |
| 20120007563 | CHARGE/DISCHARGE CONTROL APPARATUS AND CHARGE/DISCHARGE CONTROL METHOD - Included are a power-generation amount calculating section calculating an expected amount of power-generation being an amount of power generated by a power generating section in the future, for each predetermined period, a power-consumption amount calculating section calculating an expected amount of power-consumption being an amount of power consumed by a power load, for the predetermined period, an excess power period determining section determining an excess power period, an excess power amount calculating section calculating an expected excess power amount, and a charge/discharge control section controlling charge/discharge of a battery so that a remaining amount of the battery at the beginning of the excess power period becomes an amount resulting from subtracting the expected excess power amount from a pre-set charge amount. | 01-12-2012 |
| 20080261111 | CONDUCTOR-MIXED ACTIVE ELECTRODE MATERIAL, ELECTRODE STRUCTURE, RECHARGEABLE BATTERY, AND MANUFACTURING METHOD OF CONDUCTOR-MIXED ACTIVE ELECTRODE MATERIAL - An object of the present invention is to enhance the electrical conductivity between active electrode materials, enhance the electrical conductivity between an active electrode material and an electrical conduction assistant agent, and enhance the conductivity between the active electrode material and a current collecting material. This invention is related in principle to a conductor-mixed active electrode material which is processed by stirring and mixing an active electrode material and a conductive material together with hard balls, an electrode structure utilizing this conductor-mixed active electrode material, a rechargeable battery, and a method of fabricating the conductor-mixed active electrode material. | 10-23-2008 |
