Abstract:
A power storage device provided with: a plurality of serially-connected power storage units having at least one cell; cell balance units connected in parallel to each of the power storage units with a switch interposed therebetween; and a controller for charging the plurality of power storage units at a first constant current value, and, when the power storage unit having the highest voltage from amongst the plurality of power storage units reaches a first potential, performing a control so as to connect the power storage unit having the highest voltage with the cell balance unit corresponding to the highest voltage and switch the charging current to a second constant current value which is smaller than the first constant current value.
Abstract:
To reliably detect a communication error status and to resolve the communication error status when reliably recovered from the error status. A count value is changed into one of up and down directions when a communication error is detected by a communication error determination unit, the count value is changed into the other direction of the up and down directions when communication being normal is detected by the communication error determination unit, a communication error status is output when the count value becomes a first threshold value, and the communication error status is resolved when the count value becomes a second threshold value different from the first threshold value.

Abstract:
There is provided a power storage device including a plurality of modules each including secondary batteries, a charging switch that controls charging to the secondary batteries, a discharging switch that controls discharging of the secondary batteries, and a voltage measuring unit that measures a voltage of the module, and a switch control unit that controls one or both of the charging switch and the discharging switch. The modules are connected in parallel. The switch control unit maintains an on state of the discharging switch for at least one of the modules for a predetermined period, and controls the charging switch of the module in which a maximum module charging current estimated based on the voltage of the module is a predetermined value or less, to be in an on state.
Abstract:
There is provided an information processing device (100) including a recipient information recording portion (124) that records recipient party information, an image recording portion that records images of the recipient party taken on the recipient party side during a call, an image extraction portion (132) that extracts an image at a predetermined point in time from the images recorded in the image recording portion, and a registration portion (134) that, after the call is ended, associates the image extracted by the image extraction portion (132) with the recipient party information and registers the associated image in the recipient party information recording portion (124).
