600W EV Circulation Pump For Auxiliary cooling system

Short Description:

The electric coolant pump is a core actuating component of the liquid-cooled battery thermal management system in electric vehicles; it drives the circulation of coolant (an ethylene glycol-water solution) through the battery pack circuit to cool or preheat the battery cells, minimize temperature differentials, and ensure safety during fast charging.

Product Description

This EV electronic water pump uses a brushless DC motor to drive the impeller for adjustable-speed operation, and the brushless motor is driven by a built-in controller. It is applicable to main cooling systems, auxiliary cooling systems of automobile engines, thermal management systems of power battery packs, as well as energy storage equipment. The Ev Coolant Pump provides power for circulating coolant and pushes coolant to flow through each heat dissipation channel, so as to maximize the efficiency of each thermal management system and ensure continuous and stable operation of equipment. Speed regulation can be realized via CAN bus to adjust its operating conditions. Apart from the basic water circulation function, the EV Circulation Pump is equipped with multiple protection functions.
