AI Technical Summary

Technical Problem

Existing dual-pump systems are prone to generating air bubbles in new energy vehicles, which reduces pump performance, and traditional control methods cannot effectively solve this problem.

Method used

Conductivity sensors are placed between adjacent water pumps. By detecting changes in the conductivity of the coolant, the pump speed is dynamically adjusted to suppress bubble formation, thus achieving early identification and active elimination of bubbles.

Benefits of technology

This improves system stability and energy efficiency, reduces the risks caused by air bubbles, and ensures the efficient operation and reliability of the water pump.
