Farad super capacitor module

Product introduction:

       Farad supercapacitor module, also known as electric doule layer capacitor, gold capacitor and farad capacitor, can store energy through polarized electrolyte. It is an electrochemical element, but no chemical reaction occurs in the process of energy storage. This energy storage process is reversible, which is precisely because this supercapacitor can be repeatedly charged and discharged hundreds of thousands of times.

Product specification:

Features of Farad supercapacitor:

(1) High power density. It can reach 102~104W/kg, which is much higher than the power density level of the battery.

(2) Long cycle life. After a few seconds of high-speed deep charging and discharging cycles of 500000 to 1 million times, the characteristics change little, and the capacity and internal resistance only decrease by 10% to 20%.

(3) Working temperature limit width. Because the adsorption and desorption speed of ions in the supercapacitor changes little at low temperature, its capacity change is far less than that of the battery. The working temperature range of commercial supercapacitor can reach - 40 ℃~+80 ℃.

(4) Maintenance free. The charging and discharging efficiency is high. It has a certain tolerance to overcharge and overdischarge. It can be stably charged and discharged repeatedly. In theory, maintenance is not required.

(5) Green. It does not use heavy metals and other harmful chemicals in the production process, and has a long life, so it is a new type of green environmental power supply.

Application field:

In emerging industrial technology fields such as high-end intelligent machine tools, solar power generation, wind power generation, etc., the demand for instantaneous power supply is very urgent. The backup power supply is required to be able to respond quickly in milliseconds or even microseconds to complete data storage and transmission. With the help of lithium ion capacitors or ultra fast charging batteries, they have the characteristics of fast response, ultra long life and high safety.

Farad supercapacitor

The following can be formulated:

Spot welding can be 2 series 6V or 3 series, 4 series or 6 series

1. In parallel with the battery, the car starts to accelerate, and the automatic transmission car suppresses the slump, which is better than before

2. In case of parallel electric vehicle, battery assisted starting of vehicle

3. Please use the charger with constant current function to fully charge the capacitor

4. Then use in parallel

5. Discharge current at least 2000 A

6. Very small leakage

7. The vehicle with 3.0 displacement can be started independently without pressure

8. The capacitor can be used in parallel with the battery for a long time, and the car can be started several times

9. If you start the car with a capacitor for 1-2 times alone, it will lose power

Farad supercapacitor cannot be used in the following states:

1) Temperature above nominal temperature

When the capacitor temperature exceeds the nominal temperature, the electrolyte will decompose, and the capacitor will generate heat and the capacity will decrease,

Moreover, the internal resistance is increased and the service life is shortened.

2) Voltage exceeding rated voltage

When the capacitor voltage exceeds the nominal voltage, the electrolyte will decompose, and the capacitor will heat up and the capacity will drop,

Moreover, the internal resistance is increased and the service life is shortened. Therefore, reducing the service voltage can improve the service life.

3) Loading of reverse voltage or AC voltage

1. Influence of ambient temperature on supercapacitor

The service life of supercapacitor is affected by the service temperature. Generally, if the service temperature is increased by 10 ℃, the service life of supercapacitor will be shortened by half. Please try to use it in a low temperature environment lower than the service temperature. If it is used beyond the service temperature, it may cause sharp deterioration and damage of the characteristics.

The use temperature of the super capacitor should not only confirm the ambient temperature and internal temperature of the equipment, but also confirm the radiation heat of the heater (power transistor, resistor, etc.) in the equipment, and the self heating temperature caused by ripple current. In addition, do not install the heater near the supercapacitor.

2. Please use the capacitor correctly according to the positive and negative pole marks.

3. Please avoid using super capacitors in the following environments.

a) The environment is directly splashed with water, salt water and oil, or is in the state of condensation and full of gas like oil or salt.

b) An environment full of harmful gases (hydrogen sulfide, sulfurous acid, chlorine, ammonia, bromine, methyl bromide, etc.).

c) Environment splashed with acidic and alkaline solvents.

d) Direct sunlight or dusty environment.

e) An environment subject to excessive vibration and shock.

4. Avoid overheating the capacitor during welding (for 1.6mm printed circuit board, the welding temperature shall be 260 ℃, and the time shall not exceed 5s).

5. Please avoid conducting circuit wiring between the outgoing poles of the super capacitor or between the solder joints of the connecting plate.

6. Overvoltage, exceeding the operating temperature range and other conditions beyond the rated conditions may cause the pressure valve to act and the electrolyte will be ejected. Therefore, please adopt the design method that has considered the possible occurrence of this abnormal condition.

7. During fast charging and discharging, voltage drop (also called IR drop) caused by internal impedance will be generated at the beginning of charging and discharging. Therefore, please adopt the design method that has considered the voltage change range.

8. If the terminals of power type high-capacity products (products above 10F) are short circuited during charging, hundreds of amperes of current will flow through, which is dangerous. Do not install or remove the battery in the charged state.

9. Do not put the capacitor into the dissolved solder, only stick solder on the guide pin of the capacitor. Do not let the welding rod contact the capacitor heat shrink tube.

10. Do not twist or tilt the capacitor forcibly after installation.

11. When the supercapacitor is used in series, there is a problem of voltage balance between individual capacitors
