Battery information acquiring apparatus |
摘要 |
There is an apparatus includes a voltage acquiring unit which acquires an inter-terminal voltage of the battery cell; a battery information acquiring circuit which acquires battery information of the battery cell with the acquired voltage being supplied as a power supply voltage and; a transformer configured to have a primary winding and a secondary winding, the primary winding being connected to a common wire; a communication circuit which transmits a signal of the battery information to a management unit, supplied with the acquired voltage as a power supply voltage; a rectification circuit which rectifies a signal of a predetermined frequency from the management unit to generate a DC voltage; and a control circuit which controls the supply of the power supply voltages to the battery information acquiring circuit and the communication circuit, the control circuit being supplied with the DC voltage as a power supply voltage. |
