Title:
CHARGING ACTIVATION CIRCUIT, CHARGING ACTIVATION APPARATUS, AND OPERATION MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/093359
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of charging. Provided are a charging activation circuit, a charging activation apparatus, and an operation machine. The charging activation circuit comprises a power switching relay, a voltage division module and a switch module, wherein a first end of the switch module is connected to the voltage division module, a second end of the switch module is connected to a first end of the power switching relay, a second end and a third end of the power switching relay are connected to a whole-vehicle power supply end, and a fourth end of the power switching relay is connected to a control module; the voltage division module is used for reducing the activation voltage of a charging pile to a target voltage, and then turning on the switch module; the switch module is used for triggering the third end and the fourth end of the power switching relay to be connected; and the power switching relay is used for activating the control module by means of the whole-vehicle power supply end. After a voltage division module reduces the voltage of a charging pile to a target voltage, a switch module is turned on, such that a power switching relay is turned on, and thus a whole-vehicle power supply end completes the activation of a control module. Thus, the invention has a simple structure and high universality.
