Storage battery control device and electrical storage device

摘要

A storage battery control device controls an assembly battery having a plurality of secondary battery cells connected to each other, including at least one integrated circuit adapted to monitor and control charging and discharging of each of the secondary battery cells of the assembly battery. A bypass capacitor is disposed in a channel connecting a positive electrode-side external terminal and a negative electrode-side external terminal of the integrated circuit to each other. At least one first current limiting element is disposed in the channel, and at least one first switch is disposed in parallel to the first current limiting element, and adapted to short the first current limiting element.

1. A storage battery control device adapted to control an assembly battery having a plurality of secondary battery cells connected to each other, comprising:
at least one integrated circuit electrically connected to the assembly battery detachably via a connector, having a power supply to supply internal power using a voltage of the assembly battery, and to monitor and control charging and discharging of each of the secondary battery cells of the assembly battery; a bypass capacitor disposed in a channel connecting a positive electrode-side external terminal and a negative electrode-side external terminal of the integrated circuit to each other; at least one first current limiting element disposed in the channel and to limit a charging current of the bypass capacitor flowing through the channel when electrically connecting the assembly battery and the integrated circuit to each other; and at least one first switch disposed in parallel to the first current limiting element, and for setting to an ON state due to supply of the internal power from the power supply to short the first current limiting element, wherein the first switch for setting to the OFF state to allow the charging current to flow through the first current limiting element in a case in which the integrated circuit is not started, and the internal power is not supplied from the power supply when the assembly battery and the integrated circuit are electrically connected to each other, and the first switch for setting to the ON state to short the first current limiting element when the internal power is supplied from the power supply after the assembly battery and the integrated circuit are electrically connected to each other to start up the integrated circuit.
