In high-power electric vehicles and commercial trucks, the coolant pump is critical to thermal safety. Traditional pumps often suffer from insufficient flow, unstable voltage adaptation, excessive noise, and weak protection—shortcomings that stand in stark contrast to the inherent advantages of advanced electric coolant pumps, which boast long service life, small size, high precision, low energy consumption, high reliability, compact structure, and strong sealing. These traditional failures lead to overheating, shortened service life, and safety risks. The Shinhoo EPL350M-00 electric coolant pump, engineered to fully leverage these electronic pump advantages, provides a reliable, high-performance solution for heavy-duty cooling scenarios.

Key Pain Points of Conventional Coolant Pumps

High power new energy platforms have strict cooling requirements. Most common pumps cannot meet these demands. Limited flow and head lead to poor heat dissipation under heavy loads. Narrow voltage ranges fail to adapt to vehicle power fluctuations, causing performance drops or shutdowns. Poor sealing and low quality materials result in leaks and early wear. Lack of intelligent control and fault feedback reduces system safety and energy efficiency. These issues directly threaten battery life, motor stability, and overall vehicle reliability.

How Shinhoo EPL350M-00 Improves Cooling Performance

The EPL350M-00 is designed for highpower thermal management systems. It provides strong hydraulic output, with a rated flow of 70 L/min at 13 m head and a maximum flow of 88 L/min. Maximum head reaches 22.46 m, ensuring stable coolant circulation under high system resistance. With a 16–32 V DC operating range and 24 V rated voltage, it adapts smoothly to voltage fluctuations in electric vehicles.

It supports PWM control for real time speed adjustment based on cooling demand, improving energy efficiency. PWM fault feedback enables real time status monitoring and system level protection. The pump uses die cast aluminum (ADC12) structure and reliable sealing for long term durability, with a design life of more than 20,000 hours. Noise is controlled at ≤61 dB(A) at 0.5 m, supporting a quiet cabin environment.

Full protection functions include idling protection, locked rotor protection, over current protection, over temperature protection, and over/under voltage protection. Automatic restart and fault diagnosis logic prevent component damage and improve system safety.

Value for High Power Electrification

For vehicle and energy storage manufacturers, the EPL350M-00 reduces warranty claims, simplifies integration, and improves product competitiveness. For end users, it provides stable temperature control, strong safety performance, low noise, and less maintenance.

Conclusion

As high-power electrification develops, the coolant pump becomes a core component for safety and efficiency. The Shinhoo EPL350M-00 solves the weaknesses of traditional pumps with stable flow, intelligent control, high durability, and full protection. It is the ideal cooling solution for heavy duty EVs and energy storage systems.
