Claim 10:
11. A battery pack, comprising: a plurality of battery cells connected in series; a plurality of voltage detection units which detect a voltage of each of the battery cells; and a control unit having a microcomputer which measures the voltages of the battery cells from the output of each of the voltage detection units, wherein
switch control circuits configured to switch on or off the outputs from the voltage detection units to the microcomputer are respectively arranged on the plurality of voltage detection units,
voltage divider circuits configured to divide the detected voltages into voltages lower than or equal to a power supply voltage of the control unit are respectively arranged on output sides of the voltage detection units,
the microcomputer has the same number of input ports respectively connected to the voltage detection units as the number of the battery cells, and has the same number of output ports respectively connected to the switch control circuits as the number of the battery cells.
