Control apparatus and battery pack

Abstract

A control apparatus controls a relay. The control apparatus includes a control element, a monitoring circuit, and a determination unit. An input signal is input to the control element. The control element outputs an output signal and a diagnostic signal. The monitoring circuit generates an output monitor signal indicating the level of the output signal. The determination unit determines whether or not the control apparatus has an abnormality, based on a relationship between the output monitor signal and the diagnostic signal. Here, the output signal is a signal for driving the relay. One terminal of the monitoring circuit is electrically connected to an output terminal of the control element for the output signal. The diagnostic signal is a signal for monitoring the state of an output destination of the output signal.
