Abstract
A measuring apparatus includes: N pairs of probes that are respectively connected to a positive electrode and an external member of N rechargeable batteries that have a capacitance connected in parallel between the positive electrode and the external member; a scanner that selectively switches to one pair of probes out of the N pairs; a measuring apparatus that measures the voltage between the selected probes; and a controller. A plurality of resistance configurations to be connected between each pair of probes are provided. After a standby time has elapsed in a state where the N pairs of probes are connected to the positive electrodes and external members of the N rechargeable batteries, the controller outputs control signals to the scanner to successively switch to each pair of probes and causes the measuring apparatus to measure the voltage between the selected probes every time switching is performed.
