Document Type and Number:
WIPO Patent Application WO/2021/239060
Kind Code:
A1
Abstract:
Disclosed are a flow measurement and control apparatus for a heat dissipation water channel, and an electrically driven vehicle. The flow measurement and control apparatus for a heat dissipation water channel comprises: a control board (100), a driving board (200) and a water pump (300), wherein the water pump (300) is arranged on a heat dissipation water channel and is used for providing power for the flowing of a cooling liquid in the water channel; the driving board (200) is used for supplying power to the water pump (300); an inverter circuit is provided on the driving board (200); and the control board (100) is used for controlling the driving board (200) to be powered on or powered off, the control board (100) adjusts the voltage of the power supplied to the water pump (300) by the driving board (200), and the control board (100) measures the magnitude of the current of the driving board (200).
