BATTERY MONITORING UNIT

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.
