摘要： A battery monitoring unit includes a control IC, a CPU, and a load circuit. In the inside of the battery monitoring unit, the control IC and the CPU each of which is a control circuit are connected to a unit internal ground that is common thereto. The load circuit is connected to a power ground different from the unit internal ground. In the inside of the battery monitoring unit, the power ground and the unit internal ground are connected with each other via a diode. The unit internal ground and the power ground are connected to an external ground that is common thereto via an electric wire extending from a first ground terminal and an electric wire extending from a second ground terminal, respectively.

摘要： A switch failure diagnosis device for using in a current path between an electric device and an electric storage device includes plural switches, a switch terminal voltage detector, and a controller. The switches are connected parallel to each other in the current path. The switch terminal voltage detector outputs a switch terminal voltage detection signal. The controller is configured to: select the switches at different time in sequence and input an open instruction signal to each switch at the time when the switch is selected; and determine, based on the switch terminal voltage detection signal output while the open instruction signal is given, that at least one of the switches has a failure if the detected voltage is in a failure determination range.

摘要： A management device 21 comprising a main control part 23 that, during charging of a plurality of power storage elements 41 connected in series, outputs a first pull-down signal to a converter 11 so as to lower a charging voltage when the cell voltage of any of the power storage elements 41 is equal to or greater than a first threshold value.

摘要： Provided is an estimation device for estimating an actual capacity of an energy storage device or a total reduction amount of the actual capacity. The estimation device includes a processor which is configured to calculate the actual capacity of the energy storage device or the total reduction amount of the actual capacity based on approximation data where a capacity change curve indicative of a transition of the actual capacity or a transition of the total reduction amount of the actual capacity with respect to an elapsed time is approximated by a plurality of straight lines.
