The film capacitor has many excellent characteristics and is a capacitor with excellent performance. Its main characteristics: small size, non-polarity, high insulation resistance, wide frequency response, its single working voltage can reach thousands of volts, no charge and discharge equalization control is needed, and multiple film capacitors can be directly connected in parallel to improve the overall Working capacity.
The analysis and research on the self-healing, temperature and frequency characteristics of film capacitors are feasible as auxiliary power sources for new energy vehicles. The results show that the film capacitor has good self-healing ability, strong over-voltage resistance, wide operating temperature range, and good high-frequency performance. As an auxiliary power source for new energy vehicles, it has obvious advantages.
Using it as a recovery of braking energy can improve the performance of electric vehicles and prolong the service life of batteries, thereby solving the problems of low on-board volume and cruising range of new energy vehicles. The capacity of the film capacitor will gradually decrease with the use of time, and its ability to withstand large currents is poor, which limits its application in the field of new energy vehicles. It needs to be further studied before it can be used in actual production. I believe this problem will be solved in the near future.
