Title:
ELECTRIC VEHICLE CONTROL DEVICE AND METHOD FOR CONTROLLING REGENERATIVE POWER
Document Type and Number:
WIPO Patent Application WO/2021/260864
Kind Code:
A1
Abstract:
This electric vehicle control device comprises a filter capacitor (6), an inverter (7), and a control device (12) that controls the actions of the inverter (7). The filter capacitor (6) smooths overhead wire voltage outputted from an overhead wire (1). The inverter (7) converts DC power stored in the filter capacitor (6) into AC power, and supplies the converted AC power to a motor (8) installed in an electric vehicle to drive the motor (8). The control device (12) is provided with a narrowing-starting voltage calculation unit (12B) that, on the basis of speed information representing the travel speed of the electric vehicle, calculates a narrowing-starting voltage, which is a set value at which regenerative power generated during deceleration braking of the electric vehicle starts to be narrowed. When the travel speed has decreased to or below a first speed K1, the narrowing-starting voltage calculation unit (12B) changes the narrowing-starting voltage to a second voltage V2 higher than a first voltage V1 that is the default value.
