Document Type and Number:
WIPO Patent Application WO/2018/109866
Kind Code:
A1
Abstract:
The present invention includes: a battery voltage detection means 206 which detects a battery voltage at the time of driving an electric motor driven by a battery; and a lowest voltage maintaining means 207 which reduces a current consumption of the electric motor and maintains the battery voltage to be equal to or greater than a prescribed voltage, when the battery voltage detected by the battery voltage detection means during driving of the electric motor is lower than the prescribed voltage. According to the present invention, a reduction in battery voltage at the time of driving can be suppressed at low cost, and the battery voltage can be maintained equal to or greater than the prescribed voltage.
