Automotive Supplier Qualifies 33uh Inductor for Electric Vehicle Battery Management Systems

Automotive component supplier AutoPower Solutions has successfully qualified a 33uh inductor from PassiveTech for use in battery management systems (BMS) of electric vehicles (EVs). The inductor is used in the BMS’s cell balancing circuit, ensuring uniform charging and discharging of individual battery cells to extend battery life and improve safety. “EV manufacturers demand components that meet stringent automotive standards for reliability and durability,” said Elena Gomez, Automotive Business Unit Manager at PassiveTech. “Our 33uh inductor undergoes rigorous testing, including 1,000 hours of thermal cycling and vibration testing equivalent to 10 years of road use, to ensure it performs flawlessly in EV applications.” The inductor’s low self-heating 特性 (self-heating characteristic) also helps maintain optimal operating temperatures within the BMS, reducing the risk of thermal runaway. AutoPower Solutions has already secured a supply contract with a major European EV maker, with production of the 33uh inductor set to begin at its dedicated automotive-grade facility in Germany.

                      Basic knowledge of Inductor Choke Coils Inductance coils are made of wires wound around an insulating tube one by one. The wires are insulated from each other. The insulating tube can be hollow, or it can contain iron cores or magnetic powder cores, referred to as inductors. Expressed by L, the units are Henry (H), Milli Henry (mH), Micro Henry (uH), 1H=10^3mH=10^6uH. A. Classification of inductance Classified according to the form of inductance: fixed inductance, variable inductance. According to the nature of the magnetic conductor: air core coil, ferrite coil, iron core coil, copper core coil. Classified by work nature: antenna coil, oscillating coil, choke coil, trap coil, deflection coil. Classified by winding structure: single-layer coil, multi-layer coil, honeycomb coil. B. the main characteristic parameters of the inductance coil 1. Inductance L The inductance L represents the inherent characteristics o...

  A Breakthrough in EMI Resistance: Common Mode Inductors Common mode inductors are gaining popularity for their effective noise-suppression abilities, particularly in high-frequency applications. By employing a bifilar-wound ferrite core, these inductors offer superior common mode and differential mode noise suppression. The high impedance created by the common mode current flowing through the coil ensures strong damping, which helps attenuate EMI signals and provides better protection for sensitive electronic devices. These small, high-quality inductors are essential for reducing interference in a variety of modern devices, from computers to LCD panels.
