Document Type and Number:
WIPO Patent Application WO/2022/105098
Kind Code:
A1
Abstract:
The present invention relates to the technical field of construction machinery. Disclosed are a control device for a motor driver, a motor driver, and an aerial platform truck. The motor driver comprises a battery side adapted to be connected to a battery and a motor side adapted to be connected to a motor, and the control device comprises: a current absorption module, configured to absorb a feedback current generated by a motor; a first switch module connected in series to a power supply circuit between the battery side and the motor side; a second switch module; and a processor configured to: determine that the battery is in a charging disabled state; determine that the motor generates a feedback current; and control the first switch module to turn off the conduction from the motor side to the battery side, and control the second switch module to switch to an on state, so that the current absorption module absorbs the feedback current. The present invention can effectively reduce the risk caused by pulse charging at low temperature.
