In the electrification wave of new energy vehicles, capacitors, as key components of power management, directly affect the safety, endurance and power performance of vehicles.
YMIN capacitors, with their advantages of high reliability, high temperature resistance and long life, have become the core support of the three-electric system (battery, motor, and electronic control) of new energy vehicles, helping electric vehicles to gallop more efficiently and stably in the future.
“Voltage Stabilizer” of Battery Management System (BMS)
The lithium battery pack of new energy vehicles is extremely sensitive to voltage fluctuations. Overvoltage or undervoltage may affect the battery life and even cause safety hazards.
YMIN solid-state aluminum electrolytic capacitors have ultra-low ESR (equivalent series resistance) and high withstand voltage characteristics. They can be accurately filtered in BMS, stabilize voltage output, and ensure the safety and efficiency of the battery pack charging and discharging process. Its high temperature durability of 105°C and life of more than 10,000 hours are perfectly adapted to the complex working conditions of electric vehicles.
“Energy buffer” driven by motor
The motor controller (MCU) will generate large current shocks during frequent start-stop and acceleration, and traditional electric devices are prone to heat failure. YMIN solid-liquid hybrid capacitors adopt high ripple current design, which can quickly respond to current changes, provide instantaneous energy buffering for IGBT modules, reduce the impact of voltage fluctuations on motors, and improve the smoothness of power output.
“High-efficiency expert” of on-board charging (OBC) and DC-DC conversion
Fast charging technology places higher requirements on the high-voltage and high-temperature resistance of capacitors. YMIN high-voltage aluminum electrolytic capacitors support voltage resistance above 450V, efficiently store energy in on-board chargers and DC-DC converters, reduce energy loss, and help 800V high-voltage platforms achieve faster charging speeds.
“Stable cornerstone” of intelligent driving systems
Autonomous driving relies on high-precision sensors and computing units, and power supply noise may lead to misjudgment. YMIN polymer solid-state capacitors provide pure power for ADAS systems with ultra-low ESR and high-frequency characteristics, ensuring stable operation of key components such as radars and cameras.
Conclusion
From battery safety to motor drive, from fast charging technology to intelligent driving, YMIN capacitors deeply empower the electrification upgrade of new energy vehicles with their advantages of high energy density, long life, and resistance to extreme environments.
In the future, with the popularization of 800V high-voltage platform and ultra-fast charging technology, YMIN capacitors will continue to innovate and provide a more reliable “electric heart” for green travel!
