Classification: CPC B  G  H  Y | IPC B  G  H

Claim 4:
5. The battery management circuit according to claim 1, comprising:
a first semiconductor integrated circuit and a second semiconductor integrated circuit,
wherein the first semiconductor integrated circuit includes the voltage measurer, a first reference signal generator that is the reference signal generator, and a first signal synchronizer,
the second semiconductor integrated circuit includes the current measurer, a second reference signal generator equivalent to the reference signal generator, and a second signal synchronizer,
the first signal synchronizer causes the first reference signal generator to perform phase matching between the first reference frequency signal in the first semiconductor integrated circuit and the first reference frequency signal in the second semiconductor integrated circuit, and
the second signal synchronizer causes the second reference signal generator to perform phase matching between the first reference frequency signal in the first semiconductor integrated circuit and the first reference frequency signal in the second semiconductor integrated circuit.
