摘要： A current command generator 117 generates a current command that indicates a value of current supplied from an inverter circuit to electric motors connected in parallel with the inverter circuit. A voltage command calculator 120 generates a voltage compensation signal for compensating a difference between a value of actual current supplied to each of the electric motors and a value of current indicated by the current command. A determiner 135 determines, based on a value obtained from the voltage compensation signal, whether or not an abnormality is occurring in at least one of the electric motors. A shutdown controller 136 shuts down, upon the determiner 135 determining that an abnormality is occurring, the power supply from the inverter circuit to the each of the electric motors.

摘要： When a continuous short circuit occurs between both terminals of a battery pack, fault, destruction and rupture of the battery can occur. Further, when a momentary short circuit occurs, a user may continue to use, without knowing thermal and electrical damage to the batteries, and reliability for the batteries is impaired, To overcome the problem, in a battery pack configured by connecting a plurality of storage batteries in series, at least one first storage battery is included which has a low capacity compared to second storage batteries during high-rate discharge, and the first storage battery undergoes polarity inversion during external short circuit, thereby preventing the other batteries from becoming damaged. There are also included a detector that detects voltage of the first storage battery, and a fault signal generator that generates an output fault signal when a voltage detected by the detector inverses.
