| 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 |
| 20120013303 | CHARGE CONTROL APPARATUS, BATTERY PACK, AND VEHICLE - A charge control apparatus for controlling how to charge a battery unit having a plurality of batteries connected in series, includes a connection control section that divides the batteries into a plurality of groups of batteries by switching connections between the batteries, according to a received current amount indicative of an amount of a current that can be received from one or more external power sources, and a charge control section that charges the groups of batteries in parallel with power received from the external power sources. | 01-19-2012 |
| 20120013180 | BATTERY CONTROL APPARATUS, BATTERY CONTROL METHOD, AND VEHICLE - A battery control apparatus comprising a battery circuit in which a plurality of batteries are connected to each other; a plurality of first switches that switch whether the batteries are connected in series or connected in parallel; a voltage detecting section that detects a maximum voltage output by the battery circuit; and a switch control section that, when the maximum voltage of the battery circuit occurring when the batteries are connected in parallel is less than or equal to a first threshold value, controls the first switches to connect at least a portion of the batteries in series. | 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 |
| 20120011706 | BATTERY ASSEMBLING APPARATUS AND BATTERY ASSEMBLING METHOD - Provided is a battery assembling apparatus comprising a selecting section that selects as battery cells to be assembled into a battery pack, from among a plurality of battery cells, battery cells having similar charge curves that indicate a relationship between voltage and charge period, which is a time period necessary for a battery cell to be charged from a first voltage to a second voltage that is higher than the first voltage. As a result, the lifetimes of battery cells and of a battery pack assembled from a plurality of battery cells can be extended. | 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 |
| 20090230767 | POWER SUPPLY SYSTEM, MULTIPLE DWELLING, AND COMPUTER PROGRAM - A power supply system for supplying power to a plurality of loads includes a plurality of fuel cells for generating and supplying power to be supplied to the respectively corresponding loads, wherein the fuel cells are provided to correspond to the plurality of loads, a power network for receiving surplus power, which is generated ‘by the fuel cells except power to be supplied to the loads corresponding to the fuel cells, and supplying the surplus power to the loads short of power, wherein the power network is coupled to the plurality of fuel cells, and a control unit for stopping power generation of a first fuel cell among the fuel cells corresponding to a first load among the loads and controlling a second fuel cell among the fuel cells to generate power to be supplied to the first load as the surplus power if an amount of power to be supplied to the first load is less than a predetermined first threshold. | 09-17-2009 |
