What are the high power characteristics of Farad capacitors?

The capacitance of a supercapacitor unit is as high as several to tens of thousands of farads. Due to the special technology used for this structure, the equivalent resistance is very low, the capacitance is large, and the internal resistance is small, so that the supercapacitor has a high peak current, so the supercapacitor has a high specific power, and its power The density is 50 to 100 times that of batteries, which can reach about 10×103W/kg. This feature makes supercapacitors very suitable for short-term high-power applications.

Use in close-range weapons. Shipborne and land-based short-range high-speed air defense artillery systems use external power supply systems, which require energy storage devices such as batteries to form an energy storage system. However, because the artillery requires instantaneous high-power energy support during the firing process, the power function of the battery is poor. , and the battery still has a series of problems such as the need for regular maintenance and poor high and low temperature performance. The super capacitor module has many advantages, such as the pulse power is nearly ten times higher than that of the battery, it can realize frequent high-power discharge, maintenance-free, good high and low temperature performance, and the specific capacity is more than 100 times higher than that of ordinary capacitors , making it a substitute for The battery is an excellent energy storage device.

low temperature initiation. In winter in northern my country, heavy trucks, tanks, tanks, etc. that use batteries as power sources are often difficult to start due to the low temperature. The ability of Farad capacitors to discharge in a low temperature environment will be significantly reduced, and the rapid increase in internal resistance will lead to a reduction in the low temperature and high current discharge performance and output power of the battery, which will make it difficult or even impossible to start the vehicle, affecting normal operations and military readiness. Supercapacitors have the characteristics of normal operation in the temperature range of -30+50℃, which can provide an excellent solution for low temperature initiation, and can play a role in maintaining the battery and extending the service life of the battery.

It is used in situations such as vehicle acceleration and climbing. The vehicle battery must have a certain capacity to meet the design requirements of the vehicle. During the driving process in the vehicle, the high-power load condition caused by sudden acceleration, braking or climbing, load and other harsh conditions requires the battery to complete the high-power discharge. The high-power function of the battery is lacking. Even if the high-power discharge can be completed, it will also affect its life. If the supercapacitor is used in parallel with the battery, the high-power advantage of the supercapacitor can be effectively compensated for the lack of battery power.
