600W 24V electronic coolant pump for EV BTMS

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 electronic water pump is a variable-speed unit featuring an impeller driven by a brushless DC motor, which is controlled by an integrated controller.
It is suitable for applications such as automotive engine primary and auxiliary cooling systems, battery pack cooling systems, and energy storage equipment. By circulating coolant to various heat dissipation channels, it enables thermal management systems to operate at peak efficiency and ensures stable performance.
The electronic circulation pump supports speed control via CAN bus, allowing for the adjustment of its operating status. In addition to its core functions, the pump is equipped with comprehensive protection features.
