With the changes in the environment in recent years, more and more people advocate low-carbon environmental protection, green travel, and thus new energy electric vehicles appear. New energy electric vehicles are often seen on the road. Electric vehicles are energy saving and easy to maintain, so they are a good choice for people who want to buy a car.
When it comes to electric vehicles, film capacitors should not be neglected. Film capacitors use metal foils as electrodes, which are stacked with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and are wound into a cylindrical structure.
According to the type of plastic film, they are also called polyethylene capacitors (also known as Mylar capacitors), polypropylene capacitors (also known as PP capacitors), polystyrene capacitors (also known as PS capacitors) and polycarbonate capacitors.
In the early days of new energy electric vehicles, electrolytic capacitors were used, but with the development of film capacitor technology, the size of film capacitors has become smaller and smaller with the same withstand voltage level. At present, most of the film capacitors used for DC support of new energy vehicles use high temperature polypropylene film as the medium. Polypropylene film capacitors used in new energy vehicles have the following advantages:
① No maintenance required for more than 10 years in a high temperature environment
② For good temperature characteristics, the temperature range is wide, from -40° to 105°
③ With self-recovery function, high reliability
④ Strong withstand voltage performance, suitable for high voltage applications
⑤ High frequency characteristics, good filtering performance
⑥ High ripple current tolerance and high current density per unit volume
⑦ No polarity, able to withstand reverse voltage
⑧ Low loss, so the heat generation of the product itself can be suppressed and energy saving can be achieved
With the popularity of new energy electric vehicles, the demand for film capacitors is also increasing. Therefore, when purchasing film capacitors, pay attention to the manufacturer's qualifications and models.
