Yes. For example, a Lead Terminal, Snap-in Terminal, Wire Terminal, and Wired connector are all available options. 

Voltage variation amongst cells could occur in a module depending on each cell’s characteristics. The variable needs to be reduced to as low as possible for the best performance. The function of reducing it is called ‘balancing’. Vinatech’s special balancing technology is applied to all Vinatech’s modules in order to make their life time as long as possible and utilize their capacitance as much as possible.   

Whether a user needs balancing or not depends on the charging condition. VINATech modules are balanced from matched products direct from the production line.
Balancing is not necessary if the maximum charging voltage leaves an available margin of 0.2V. For example, a maximum charging voltage for a 2.7V cell is 2.5V, then 0.2V is left vacant, so it doesn't need to be balanced. 

However, if an application charges fully to maximum voltage like 2.7V or 3.0V, then it should be balanced. 
Active balancing takes up more PCB space, so because of space constraint, we usually recommend a passive balancing. Active balancing is more costly (x2 in case and has energy needs too).
If the user doesn’t’ want passive balancing, then identify the required charging condition. If the charging condition leaves enough margin over 2.0v, then the balancing is not necessary. 
With enough margin, the user can use a module without balancing as this will lead to the shortening of life time of the Supercapacitor

When using Hy-Cap Electric Double-Layer Capacitor, please make sure of polarity(+and ‒marking) when using and do not use higher than rated voltage. Also please use within the recommended operating temperature range and store within the recommended storage temperature range. In case of connecting more than 2 units for modules, we recommend “unit voltage - 0.2V” per unit for the sake of safer voltage balancing (e.g. 2.5V in case of 2.7V unit). When soldering, be aware of proper conditions in order to avoid excessive heat or time on the products. 

※ For more details, please contact us.

The total cycle time for our Hy-Cap EDLC is 500,000~1,000,000, and the cycle time for Hybrid type Hy-Cap is 100,000.
 
However, the working conditions such as temperature and voltage could affect the total cycle time.  

Even though a fire may take place at the same time as the blackout, the elevator carries passengers all the way to a safe floor and opens the door, by activating the Super Capacitor. 

In case of no Super Capacitor
•Passengers boarding on 30th floor
•Blackout; elevator stops moving
•Call to emergency service for rescue
•A fire on 20th floor; fire alarm activated
•Emergency service arrives for the rescue

In case of a Super Capacitor
•Passengers boarding on 30th floor
•Blackout; Super Capacitor activated
•Elevator stops on 28th floor; door opens passengers disembark
•Announcement for prevention of boarding
•A fire on 20th floor; fire alarm activated

Regenerative Energy in elevators consist of an all-in-one converter/inverter, car, discharge resistor and balance weight.

Regenerative Energy in elevators generates the energy when the elevator goes up or down, according to weight difference between the car load and the balance weight.

If the car load is heavier than the balance weight, Regenerative Energy is generated while the car moves down; if the former is lighter than the latter, the energy is generated while the car moves up.
