摘要:
Terminals of a battery apparatus is connected to terminals of a vehicle body controller, respectively, and terminals of the battery apparatus are connected to terminals of a charger, respectively. The terminals are connected to each other through a communication path, and the terminals are connected to each other through a communication path. A termination resistor and a switch are connected in series between the communication paths. A microcomputer controls the switch based on a voltage of the terminal.

A motor control device that controls the driving of a motor having a permanent magnet provided at a rotor has: an angle detector that detects the angle of the rotor by use of an angle sensor; a current detector that detects, as a detected current, the outflow current from or inflow current to a direct-current power source serving as the source for driving the motor; and an angle corrector that corrects the detected angle based on the detected current. The driving of the motor is controlled by use of a corrected angle obtained through the correction by the angle corrector.
