Vishay, FDK, TDK magnetic parts giant push scheme to ensure electric vehicle safety

Recently, a news that “the owner of BYD was killed by electricity” was circulating in the circle of friends. According to the news, on April 23, 2016, a BYD electric taxi drove to Taiyuan South Station. The driver just delivered the passengers and the passengers went down. After the car, the driver was electrocuted in the car.

Although this incident was smashed yesterday as a driver's heart attack, the safety of electric vehicles still worries everyone. Electric vehicle safety accidents occur frequently, although the culprit is the battery, but some are related to short circuits. According to the "Electronic Transformer and Inductor Network" reporter, when the circuit is short-circuited, the electrolyte inside the battery will be electrolyzed at high temperature to generate gas, which causes the internal pressure of the car to rise, eventually causing the electric car to ignite and even explode.

Therefore, preventing circuit short circuit plays an important role in ensuring the safety of electric vehicles. Circuit short circuit is related to the power, aging, quality and other factors of various components, so the fundamental problem lies in the improvement of component performance. Recently, magnetic heads such as Vishay and FDK have introduced high-performance magnetic components for electric vehicles.

Vishay

Vishay introduces a small form factor planar transformer from 1kW to 3kW, 70mm x 53mm x 22mm and weighs 170g - PLA51. This product is suitable for electric vehicle chargers. Compared with traditional transformers, this product is more than 99% efficient. Reduce power loss, effectively extend product aging speed and protect circuit safety.

PLA51

FDK

FDK introduced a new type of manganese-zinc (Mn-Zn) ferrite material, the 6H60T, which can be used in electric vehicle power transformers.

6H60T loss is 15% lower than the original product "6H60" (use environment: 140 °C), and can also be scaled production with the industry standard core shape "UU79/129A", which not only reduces costs, but also saves energy. For electric vehicles, low-loss power transformers can improve the efficiency of electronic equipment and protect the safety of electric vehicles.

TDK

TDK has developed the power inductor CLF7045NI-D for electric vehicle power supply circuits. This product is capable of supporting a wide temperature range of -55 ° C to +150 ° C and is also capable of withstanding the engine compartment because of its high heat resistance. The harsh environment. More importantly, this product also introduces a fully automated assembly line manufacturing process, which not only provides high reliability and high quality, but also enables manufacturers to supply high efficiency.

Electric vehicle explosions, leakage and other safety accidents are shocking. To reduce the frequency of such safety accidents, we need to work together by upstream and downstream manufacturers to do our best to ensure the quality and safety and create a good foundation for our safe driving.
