As new energy vehicles accelerate toward higher voltages and smarter technologies, thermal management systems have become a core component for ensuring vehicle performance and safety. In critical applications such as motor cooling, battery temperature control, and air conditioning compressors, the stability of capacitors directly determines system efficiency. YMIN Electronics, leveraging automotive-grade capacitor technology, provides high-performance solutions for thermal management systems, helping automakers overcome heat dissipation challenges in high-temperature and high-vibration environments!
The “High-Temperature Buster” for Thermal Management Systems
To address the high-temperature pain points of thermal management systems, YMIN has launched several innovative products:
• VHE Series Solid-Liquid Hybrid Capacitors: Designed specifically for automotive electronic thermal management, they feature ultra-low ESR and ultra-high ripple current capability. They operate stably at temperatures up to 125°C, precisely addressing current fluctuations in modules like PTC heaters and electronic water pumps.
• LKD Series Liquid Aluminum Electrolytic Capacitors: Featuring a 105°C high-temperature design, they offer airtightness exceeding industry standards and a lifespan of 12,000 hours, making them suitable for compact applications like air conditioning compressor controls.
• Film Capacitors: With a withstand voltage of up to 1200V and a lifespan exceeding 100,000 hours, their ripple tolerance is over 30 times that of traditional electrolytic capacitors, providing a safety barrier for motor controllers.
Technical Advantages: Stable, efficient, and long-lasting.
• High-temperature stability:
Solid-liquid hybrid capacitors exhibit minimal capacitance change over a wide temperature range, with a capacity retention rate exceeding 90% after long-term use, eliminating the risk of high-temperature failure.
• Structural Innovation:
A special riveted winding process improves capacitance density, resulting in a 20% higher capacitance than the industry average for the same volume, contributing to system miniaturization.
• Intelligent Compatibility:
Capacitors can be integrated into thermal management control circuits (such as water pump/fan driver ICs) to support real-time power regulation and improve energy efficiency.
Full Coverage of Application Scenarios
From battery thermal management to motor cooling, YMIN Capacitors offer comprehensive solutions:
• PTC Heating Modules:
OCS magnetic current sensors combined with high-voltage capacitors precisely control heating current to ensure battery activity in low-temperature environments.
• Air Conditioning Compressors:
VHT series solid-liquid hybrid capacitors reduce high-frequency losses and improve energy efficiency.
• Electronic water/oil pumps:
Low-ESR capacitors reduce heat generation in the drive circuit and extend pump life.
Future Layout: Intelligent Thermal Management Ecosystem
YMIN is promoting the integration of capacitor technology and AI control strategies. The NovoGenius series SoC chip solution, showcased at the 2025 conference, dynamically optimizes thermal management energy consumption by adjusting water pump/fan speed in real time, providing forward-looking support for 800V high-voltage platforms and solid-state batteries.
Every evolution in thermal management systems is a double victory for energy efficiency and safety!
With “domestic high-end automotive-grade capacitors” at its core, YMIN continuously refines its manufacturing process and quality control, partnering with automakers to build an intelligent and safe future for new energy vehicles!
