Abstract
With the continuous iteration of power battery technology for new energy vehicles, the control performance and reliability of the battery thermal management system have become the core factors restricting the range and safety performance of new energy vehicles. The electric water pump, as a key component of the thermal management system, and its drive control technology directly determines the operational efficiency and stability of the thermal management system. This paper focuses on the core component of the electric water pump drive chip, combines actual application schemes, systematically analyzes its technical requirements and selection logic, and mainly studies the key indicators such as reliability, temperature adaptation range, control accuracy, integration degree, and control algorithm of automotive-grade drive chips. It compares the technical advantages and disadvantages of three mainstream architecture schemes: fully integrated, pre-drive+separated power devices, and "MCU+"; verifies the application value of sensorless field-oriented control algorithm, and analyzes the technical implementation effectiveness through typical chip case studies. The research results show that: the high-integration single-chip solution has become the current mainstream selection; the wide temperature working range of -40~150℃, complete protection mechanism, and low power consumption characteristics are the core performance requirements of the drive chip; algorithm hardwareization and intelligent adaptive control will be the core direction of future technological evolution. The research in this paper can provide a reference for the selection design and technological innovation of the drive chip for electric water pumps in power battery.
