OEM Super Capacitance Factories - Hybrid Supercapacitor Car Battery 24V – JEC

Features

Cylindrical shape structure, large capacitance, low internal resistance, in line with ROHS lead-free requirements
Fast charge/discharge. Provides instantaneous high current output
Fast charging of products has become a trend. Supercapacitors can not only improve the fast charging capability of products, but also ensure the safety and stability of products.
Tailor-made according to customer’s product needs. We can customize different specifications of single super capacitors, combined modules, and related energy control systems

Application

Energy storage system, large-scale UPS (uninterruptible power supply), electronic equipment, wind pitch, energy-saving elevators, portable power tools, etc.

Certification

JEC factories are ISO-9000 and ISO-14000 certified. Our X2, Y1, Y2 capacitors and varistors are CQC (China), VDE (Germany), CUL (America/Canada), KC (South Korea), ENEC (EU) and CB (International Electrotechnical Commission) certified. All of our capacitors are in line with the EU ROHS directives and REACH regulations.

FAQ
What are the main application categories of supercapacitors?
① Backup power supply (short power consumption time, high reliability and long life are required): wind turbine pitch, electricity meter, server, etc.;
② Power-down data protection and communication assistance: server RAID card, driving recorder, distribution network equipment, FTU, DTU, etc.;
③ Provide instant high power: water meters, medical X-ray machines, construction machinery, aircraft doors, etc.;
④ Fast charging and discharging: buses, AGVs, power tools, toys, etc.;
⑤ Use with batteries: car start-stop system, water meter, etc.;
⑥ Micro-grid regulation, smooth grid fluctuations, etc.

Why do capacitors lose energy so quickly?
Before answering this question, we need to know “what can affect the leakage current of a supercapacitor?”
From the point of view of the product manufacturing itself, it is the raw materials and manufacturing processes that affect the leakage current.
From the perspective of the use environment, the factors that affect the leakage current are:
Voltage: the higher the working voltage, the greater the leakage current
Temperature: the higher the temperature in the use environment , the greater the leakage current
Capacitance: the greater the actual capacitance value, the greater the leakage current.
Normally under the same environment conditions, when the supercapacitor is in use, the leakage current is correspondingly smaller than when it is not in use.
Supercapacitors have super large capacitance and they can only work under relatively low voltage and temperature. When the voltage and temperature radically increase, super capacitor’s capacitance will largely decrease. In order words, it lose electricity radically.
