In the design of a series of new products such as energy collection, office automation and backup systems, supercapacitor has attracted the attention of the design team. These supercapacitor batteries have efficient storage capacity and can quickly release energy as required. To ensure peak performance and long product life cycle, the voltage of supercapacitor must be balanced. Farad capacitor If imbalance occurs due to the difference of leakage current between batteries, energy dissipation may be triggered, leading to premature failure of supercapacitor batteries.

Supercapacitors are used more and more widely because they can be used together with other batteries or used as substitutes for batteries in applications requiring many fast charging and discharging cycles. Super capacitor module It is usually used for short-term energy storage, regenerative braking and static RAM backup.

In order to prevent this imbalance, a balance circuit is needed. This balance circuit automatically corrects the effect caused by the constantly changing leakage current, so that the voltage passing through each supercapacitor is within a limited range. All of these require little additional leakage current or power consumption.

An optional resistor can also be connected to each pair of supercapacitors. Generally, the supercapacitor is open. However, if the equipment is not inserted at the supercapacitor location, a zero ohm jumper resistor should be installed at its corresponding location.

Super capacitor without automatic balance: leakage current will lead to voltage imbalance and power loss. Super capacitor manufacturer The power system designer must compensate for the leakage current of each supercapacitor battery. Otherwise, if the voltage exceeds the rated battery voltage for a period of time, the working life of the supercapacitor may be shortened or even not damaged.
