In an identifier assignment system for assigning identifiers to respective voltage monitors to be connected to respective battery units, each measuring unit measures elapsed time information indicative of an elapsed time that has elapsed since a predetermined point of time after an activation of the corresponding voltage monitor based on power supplied from the corresponding battery unit connected to the corresponding voltage monitor. Each measuring unit is also configured to wirelessly transmit the elapsed time information about the corresponding voltage monitor. A comparison unit performs a comparison task of comparing the elapsed times of the respective voltage monitors with each other. An assignment unit is configured to assign unique identifiers to the respective voltage monitors in accordance with a result of the comparison task.

Identifier assignment method and system

A monitoring apparatus includes: a monitoring portion that monitors a voltage of each of battery cells connected in series, each of the battery cells having an electrode terminal; and a wiring portion that connects the monitoring portion and the electrode terminal. The wiring portion includes a first flexible substrate and a second substrate that have flexibility and are integrally linked with each other. A linking part where the first flexible substrate and the second flexible substrate are linked is bent. The first flexible substrate is connected with the electrode terminal. The second flexible substrate is connected with the monitoring portion. One of the first flexible substrate and the second flexible substrate includes an arm. Another of the first flexible substrate and the second flexible substrate other than the one including the arm includes a slit. The arm is fixed to the slit, causing the linking part to be reinforced.

Monitoring apparatus

A battery monitoring apparatus that monitors a temperature of a battery includes a temperature detecting unit, a power supply, a limiting unit, a temperature acquiring unit, and determining unit. The temperature detecting unit is provided for the battery. Resistance of the temperature detecting unit changes with temperature. The power supply applies a voltage to the temperature detecting unit. The limiting unit limits the application of voltage to the temperature detecting unit from the power supply. When the limiting unit is not limiting the application of voltage, the temperature acquiring unit determines the temperature of the battery based on a voltage-drop amount in the temperature detecting unit. When the limiting unit is limiting the application of voltage, the determining unit makes a determination regarding a short circuit between the temperature detecting unit and the battery based on the voltage applied to the temperature detecting unit.
