Issued 2019-07-02
Assembled Battery Monitoring Apparatus And Assembled Battery Monitoring System
An assembled battery monitoring apparatus includes: a first operation functioning device that carries out a monitoring process on an assembled battery configured by a plurality of battery cells connected in series and communicates with a host controller only in an ordinary operational timing in which the host controller controls an external power source to supply an operation power source; a second operation functioning device that carries out the monitoring process on the assembled battery in the ordinary operational timing and in a non-ordinary operational timing in which the external power source stops to supply the operation power source; and a power supply switching device that performs switching so as to enable the assembled battery to supply the operation power source in the non-ordinary operational timing.

- 1. An assembled battery monitoring apparatus comprising:
a first operation functioning device that carries out a monitoring process on an assembled battery configured by a plurality of battery cells connected in series and communicates with a host controller through a communication input-and-output interface and a communication controller only in an ordinary operational timing in which the host controller controls an external power source to supply an operation power source; a second operation functioning device that carries out a monitoring process on the assembled battery in response to a command received by the first operation functioning device from the host controller in the ordinary operational timing and in a non-ordinary operational timing in which the external power source stops supplying the operation power source; a power supply switching device that performs switching so as to enable the assembled battery to supply the operation power source in the non-ordinary operational timing; a first inner power circuit that is configured to receive a power supply from the external power source or the assembled battery to supply the operation power source to the first operation functioning device; and a second inner power circuit that is configured to receive a power supply from the external power source or the assembled battery to supply the operation power source to the second operation functioning device, wherein the power supply switching device stops the first inner power circuit from supplying the operational power source to the first operation functioning device in response to detecting a voltage drop in the external power source and changes a supply source of the operation power source in response to the command received by the first operation functioning device from the host controller.
- 8. An assembled battery monitoring apparatus comprising:
a first operation functioning device that carries out a monitoring process on an assembled battery configured by a plurality of battery cells connected in series and communicates with a host controller only in an ordinary operational timing in which the host controller controls an external power source to supply an operation power source; a second operation functioning device that carries out a monitoring process on the assembled battery in the ordinary operational timing and in a non-ordinary operational timing in which the external power source stops to supply the operation power source; and a power supply switching device that performs switching so as to enable the assembled battery to supply the operation power source in the non-ordinary operational timing, wherein the second operation functioning device includes a watchdog timer to be reset when the second operation functioning device receives a reset signal sent by the host controller within a time interval; and the power supply switching device performs the switching so as to enable the operation power source supplied from the assembled battery when the watchdog timer overflows.
- 9. An assembled battery monitoring apparatus comprising:
a first operation functioning device that carries out a monitoring process on an assembled battery configured by a plurality of battery cells connected in series and communicates with a host controller only in an ordinary operational timing in which the host controller controls an external power source to supply an operation power source; a second operation functioning device that carries out a monitoring process on the assembled battery in the ordinary operational timing and in a non-ordinary operational timing in which the external power source stops to supply the operation power source; and a power supply switching device that performs switching so as to enable the assembled battery to supply the operation power source in the non-ordinary operational timing, wherein the second operation functioning device includes an oscillation monitor for monitoring an oscillation state of a clock signal; and the power supply switching device performs the switching so as to enable the assembled battery to supply the operation power source when an abnormality in the oscillation state is detected.
