The capacitance of a super capacitor cell can reach several to tens of thousands of methods. Because this structure adopts special technology, its equivalent resistance is very low, its capacitance is large, and its internal resistance is small, so the supercapacitor has a very high peak current, so the supercapacitor has a very high specific power, its power density is 50 to 100 times that of the battery, which can reach 10 × About 103W/kg, this feature makes super capacitors very suitable for use in short-time high-power occasions.

Application in near defense weapons. Shipboard and land-based short-range high-speed air defense artillery systems use an external power supply system, which requires energy storage equipment such as batteries to form an energy storage system. However, because the artillery needs instantaneous high-power energy support during firing, the power function of the batteries is poor, and the batteries still have a series of problems such as periodic protection, poor high and low temperature functions, etc. Super capacitor module The super capacitor has many advantages, such as nearly ten times higher than the pulse power than the battery, can complete frequent high-power discharge, free of protection, good high and low temperature function, and its specific capacity is more than 100 times higher than that of ordinary capacitors, which makes it an excellent energy storage device to replace batteries.

Start at low temperature. In winter in northern China, heavy trucks, tanks, and tank vehicles that use batteries as the power source are often difficult to start because of the low temperature. Farad capacitor In low temperature environment, the discharge capacity decreases significantly and the internal resistance increases sharply, which will lead to the reduction of the low temperature high current discharge function and output power of the battery, making it difficult or even impossible to start the vehicle, affecting normal work and military readiness. The super capacitor has the characteristics of normal operation within the temperature range of - 30+50 ℃, can provide excellent solutions for low-temperature starting, and can protect the battery and extend the service life of the battery.

The application in vehicle acceleration, climbing, etc. It is necessary for the vehicle battery to have a certain capacity to meet the design requirements of the vehicle. High power load conditions caused by sudden acceleration, braking or climbing, load and other adverse conditions during driving in the vehicle require the battery to complete high power discharge. However, the lack of high power function of the battery has an impact on its life even if it can complete high power discharge, If the super capacitor is used in parallel with the storage battery, the high power advantage of the super capacitor can effectively compensate for the lack of battery power.
