Specification

BATTERY CONTROL DEVICE, CONTROL METHOD, CONTROL SYSTEM AND ELECTRIC VEHICLE Technical Field [0001] The present disclosure relates to a control device, a control method, a control system and an electric vehicle. Background Art [0002] Secondary batteries are used as a backup power supply or an automobile power supply in addition to various electronic devices. When a secondary battery is used in low temperatures (for example, 0 degrees Celsius or lower), there is a possibility of the performance thereof deteriorating. Citation List Patent Literature [0003] PTL 1: Japanese Unexamined Patent Application Publication No. 2009-142069 PTL 2: Japanese Unexamined Patent Application Publication No. 2006-210244 Summary Technical Problem [0004] In PTL 1 and PTL 2, a technology is disclosed preventing deterioration in the per formance of a secondary battery accompanying usage in low temperatures in advance by using the secondary battery after warming. However, the technology disclosed in PTL 1 and PTL 2 prevents deterioration in the performance of a secondary battery ac companying usage in low temperatures in advance (e.g., prior to when the battery has deteriorated). In a case where the performance of the secondary battery is deteriorated, there is a problem where it is difficult for the performance of the secondary battery to be recovered without, for example, replacement of the secondary battery. [0005] Accordingly, in various embodiments, it is desirable to provide devices (e.g., control devices), methods (e.g., control methods), systems (e.g., control systems), and electric vehicles that recover the performance of a secondary battery (e.g., improve dete rioration of the secondary battery). Solution to Problem [0006] Various embodiments of the present disclosure relate to battery packages including: a power storage portion; and a control device, where the control device determines if a first temperature of the power storage portion is higher than a predetermined tem perature, and if the first temperature is higher than the predetermined temperature, discharges the power storage portion at a first discharge rate. In some embodiments, the battery may be adapted for use with an electronic device, where the battery includes the battery package. The electronic device may be a vehicle, and a vehicle can include the battery packages disclosed herein. [0007] Some embodiments of the present disclosure further relate to battery packages adapted for use with a power storage device, including: a power storage portion; and a control device, where the control device functions to determine if a first temperature of a power storage portion is higher than a predetermined temperature, and if the first temperature is higher than the predetermined temperature, discharge the power storage portion at a predetermined first discharge rate. [0008] Further embodiments are directed towards methods of controlling power storage in a battery package, including: determining if a first temperature of the power storage portion is higher than a predetermined temperature, and if the first temperature is higher than the predetermined temperature, discharging the power storage portion at a predetermined first discharge rate. Advantageous Effects of Invention [0009] According to at least one embodiment, it is possible to improve or recover the per formance of a secondary battery. Brief Description of Drawings [0010] [fig. 1]Fig. 1 is a block diagram showing one example of a configuration of a control system according to certain embodiments; [fig.2]Fig. 2 is a flowchart for describing one example of a main process in a control system according to certain embodiments; [fig.3]Fig. 3 is a flowchart showing one example of a process in a first recharging mode according to certain embodiments; [fig.4]Fig. 4 is a flowchart showing one example of a process in a discharge mode according to certain embodiments; [fig.5]Fig. 5 is a flowchart showing one example of a process in a second recharging mode according to certain embodiments; [fig.6]Fig. 6 is a diagram for describing one example of changes in capacity and changes in voltage during discharging according to certain embodiments; [fig.7]Fig. 7 is a diagram for describing one example of changes in DOD and changes in voltage during discharging according to certain embodiments; [fig.8]Fig. 8 is a flowchart showing one example of a processing flow in a deterioration detection mode according to certain embodiments; [fig.9]Fig. 9 is a diagram for describing one example of changes in capacity and changes in deltaQ/deltaV during discharging according to certain embodiments; [fig. 10] Fig. 10 is a flowchart showing one example of a processing flow in a recovery mode according to certain embodiments; [fig. 1l]Fig. 11 is a diagram for describing one example of an effect according to certain embodiments; [fig.l2A]Fig. 12A is a diagram for describing one example of an effect according to certain embodiments; [fig.l2B]Fig. 12B is a diagram for describing one example of an effect according to certain embodiments; [fig.l3]Fig. 13 is a diagram for describing one example of an effect according to certain embodiments; [fig. 14] Fig. 14 is a diagram for describing an application example according to certain embodiments; and [fig.l5]Fig. 15 is a diagram for describing an application example according to certain embodiments. Description of Embodiments [001 1] Below, various embodiments of the present disclosure are described with reference to the drawings. Further, the description is given in the following order. First Embodiment Modification Examples Application Examples [0012] The various embodiments described below are examples of the present disclosure; however, the content of the present disclosure is not limited to these illustrative em bodiments. First Embodiment [0013] Example of Secondary Battery [0014] In the present disclosure, illustrative examples of secondary batteries include lithium ion secondary batteries including a cathode active material and a carbon material, such as graphite, as an anode active material. The cathode material is not limited, and a material containing a cathode active material having an olivine structure may be used. [0015] Cathode active materials having an olivine structure may be used, including a lithium iron phosphate compound (LiFeP0 4) or a mixed lithium iron phosphate compound containing a heteroatom (e.g., LiFexMi_xP0 4; where M is one or more types of metal, and x is 0
