>Main characteristics of nickel cadmium battery
1.Positive terminal
There is a polarity sign "+" by the positive terminal (painted red) on the accumulator cap.
2.Plug
Provides electrolyte filling and free gas outlet when charging.
3.Negative terminal
4 Connecting element of contact banks into a block Bolted connection and welded connection.
Provides connection between electrodes and a terminal.
5.Contact bank Contact bank, welded to electrode, provides electrode's connection with the connecting element of contact banks.
Punched contact blocks are used for assembly of bolted connection electrode blocks.
6.Electrodes
7.Separator It divides positive and negative electrodes and provides free circulation of electrolyte between the electrodes.
8.Case It is made of plastic and metal. A rubber electrically insulating cover is put onto a metal accumulator case.
>NI-CD battery's application
* Emergency starting power for diesel engine.
* Subways.
* Diesel locomotives
* UPS systems.
* Light Rail Vehicles.
* AGV( Automated Guided Vehicles).
* Electric Boats.
* Hospital carts.
* Tractors for airports.
>Competitive Advantage
1. The charge and discharge can be repeated more than 500 times, which is very economical;
2. The internal resistance is small, and it can be used for high current discharge. When it is discharged, the voltage changes little.
As a DC power supply, it is a battery of excellent quality;
3. Because of the completely sealed type, there will be no electrolyte leakage, and there is no need to replenish the electrolyte;
4. Compared with other types of batteries, nickel-cadmium batteries can be overcharged or overdischarged,
and the operation is simple and convenient;
5. The performance will not be degraded after being placed for a long time, and the original characteristics can be restored after charging;
6. The usable temperature range is wide;
7. Because it is made of a metal container, it is mechanically strong.
