3S 6A Active Balancer Super Capacitor Equalizer Price in Bangladesh

The 3S 6A Active Balancer Super Capacitor Equalizer is an active voltage-balancing module designed for supercapacitor banks consisting of three cells or capacitor groups connected in series. Its primary purpose is to help maintain a more consistent voltage distribution between the individual capacitor sections during charging, discharging, and energy-storage operation.

Supercapacitors are often connected in series when a higher operating voltage is required. However, individual supercapacitor cells can have slightly different leakage currents, capacitance values, internal resistance, and voltage characteristics. If these cells are connected directly in series without suitable voltage management, one capacitor can potentially reach a higher voltage than the others.

Voltage imbalance is particularly important with supercapacitors because individual cells generally have relatively low maximum working voltages. Many commonly used supercapacitor cells have a maximum voltage around 2.7V, although the exact voltage rating depends on the specific capacitor. Therefore, a series capacitor bank requires appropriate voltage balancing.

The 3S 6A Active Balancer is designed to address this problem by transferring energy between capacitor sections rather than simply dissipating excess energy as heat. This is the fundamental difference between an active balancer and a basic passive balancing circuit.

In a passive balancing circuit, excess voltage is typically reduced by allowing current to flow through resistors. This method is simple but continuously wastes some energy as heat. An active balancing circuit instead uses electronic switching and energy-transfer circuitry to redistribute energy from a higher-voltage cell toward lower-voltage cells.

The 6A rating represents the module’s specified active balancing-current class. The actual current achieved during operation can vary depending on voltage differences, operating conditions, temperature, wiring, and the particular module design.

The 3S configuration means the module is intended for three series-connected capacitor sections. It is important to understand that “3S” refers to three series positions and does not mean that three supercapacitors can automatically be connected to any voltage. The maximum allowable voltage of each capacitor and the total bank voltage must always remain within the specifications of the capacitors and balancing module.

For example, if three supercapacitors are each rated for 2.7V, the theoretical total series voltage is approximately 8.1V. However, the actual operating voltage should be determined according to the capacitor manufacturer’s specifications and the balancing module’s requirements. The equalizer should never be used to justify exceeding the voltage rating of any individual capacitor.

Active balancing can be particularly useful in applications where the capacitor bank is charged and discharged repeatedly. By helping equalize the voltage between series sections, the module can improve the usable energy-storage capacity of the bank and reduce the possibility of one capacitor becoming overvoltage while another remains underutilized.

The module can be useful in supercapacitor energy-storage systems, regenerative-energy projects, DC backup systems, robotics, experimental power systems, pulse-power applications, and educational electronics projects.

It is important to note that an active balancer is not necessarily a complete charging controller or protection system. The external charging source must still be appropriate for the total capacitor-bank voltage. The capacitors themselves must also be correctly selected and wired.

Unlike a lithium-ion BMS, a supercapacitor equalizer is designed specifically around capacitor voltage balancing. A lithium battery BMS should not be substituted for a supercapacitor balancing circuit unless the manufacturer explicitly specifies compatibility.

The compact design of a 3S active balancer makes it convenient for integrating voltage equalization into custom capacitor banks. It can be used alongside appropriate fuses, switches, contactors, charging circuits, and other protection equipment depending on the application.

Overall, the 3S 6A Active Balancer Super Capacitor Equalizer is a useful component for maintaining more uniform voltage distribution across three series-connected supercapacitor sections and improving the practical utilization of a series capacitor bank.

What is a Super Capacitor Equalizer?

A supercapacitor equalizer is an electronic circuit that helps maintain similar voltage levels across individual supercapacitors connected in series.

When capacitors are connected in series, differences in leakage current and capacitance can cause their voltages to become unequal.

For example:

Capacitor 1 → Capacitor 2 → Capacitor 3

Without suitable balancing, one capacitor may develop a higher voltage than the others.

An equalizer monitors these voltage differences and transfers or dissipates energy as necessary to maintain a safer and more balanced distribution.

What Does 3S Mean?

3S means three capacitor cells or groups are connected in series.

For example:

C1 + C2 + C3 = 3S capacitor bank

The total voltage is the sum of the individual capacitor voltages.

If three identical 2.7V supercapacitors are connected in series, their nominal maximum voltage arrangement would theoretically be around 8.1V, subject to the manufacturer’s specifications and balancing requirements.

The equalizer helps prevent significant voltage differences between C1, C2, and C3.

Working Principle

The active balancer continuously monitors the voltage of the individual capacitor sections.

Suppose one capacitor has a higher voltage than another:

C1 = Higher Voltage
C2 = Lower Voltage

The balancing circuit detects this difference and activates its energy-transfer circuitry.

Instead of simply converting the excess energy into heat through a resistor, an active balancer transfers energy from the higher-voltage section toward the lower-voltage section.

This process helps bring the capacitor voltages closer together.

With three capacitor sections, the module can monitor the voltage distribution across the complete series stack and redistribute energy where required.

The exact switching topology varies by module design, but active balancing generally provides better energy efficiency than simple resistive balancing when substantial voltage differences need to be corrected.

Active Balancer vs Passive Balancer

There are two common approaches to voltage balancing.

Passive Balancing

Passive balancing generally uses resistors to bleed current from higher-voltage capacitor sections.

Advantages:

• Simple circuit
• Low cost
• Easy to implement

Disadvantages:

• Wastes energy as heat
• Balancing current can be limited
• Resistors may require thermal management

Active Balancing

An active balancer transfers energy between capacitor sections.

Advantages:

• More efficient energy redistribution
• Can support higher balancing currents
• Less energy wasted as heat compared with resistive balancing
• Useful for larger energy-storage systems

The 3S 6A Active Balancer uses the second approach.

Frequently Asked Questions (FAQ)

What does 3S mean on this supercapacitor balancer?

3S means the module is designed for three supercapacitor cells or capacitor groups connected in series.

What does 6A mean?

The 6A specification indicates the module’s rated active balancing-current class. Actual balancing current depends on the voltage difference and operating conditions.

Why is balancing necessary for supercapacitors?

Series-connected supercapacitors can develop different voltage levels because of variations in capacitance and leakage current. Balancing helps keep individual capacitor voltages within appropriate limits.

Is this module a supercapacitor charger?

No. It is an active balancing/equalizing module, not a complete charging controller. Use an appropriate charging system for the total capacitor-bank voltage.

Can I use this module with lithium-ion batteries?

It should not be treated as a lithium-ion BMS. It is designed for compatible supercapacitor series configurations, and lithium batteries require an appropriate BMS designed for their chemistry.

Can I connect three 2.7V supercapacitors to it?

A 3S arrangement of 2.7V-rated cells gives a theoretical total of approximately 8.1V. However, you must verify that the exact equalizer’s operating range and voltage limits are compatible with the capacitor bank before connecting it.
