Nickel-Cadmium (Ni-Cd) batteries have become a critical component in the railway industry due to their reliability, durability, and capacity to withstand challenging conditions. These batteries are extensively used in locomotives, passenger trains, and signaling systems, playing a key role in ensuring smooth and safe operations.
Applications in Railways
- Backup Power Systems: Ni-Cd batteries serve as backup power sources for critical systems like signaling, communication, and emergency lighting. They ensure uninterrupted operation during power failures.
- Auxiliary Systems: These batteries power auxiliary systems such as air conditioning, lighting, and control units in trains, especially during standstill periods or power supply interruptions.
- Engine Starting: Ni-Cd batteries are used for starting diesel engines in locomotives, providing the necessary cranking power even under low temperatures.
Why Ni-Cd Batteries Are Preferred
- High Reliability: The railway environment demands a dependable energy source. Ni-Cd batteries have a proven track record of reliability in critical applications.
- Wide Temperature Range: These batteries function effectively in extreme temperatures, from freezing winters to scorching summers.
- Durability: With a long lifespan and resistance to deep discharge, Ni-Cd batteries can endure the demanding cycles of railway operations.
- Low Maintenance: Compared to other battery types, Ni-Cd batteries require less maintenance, making them cost-effective over time.
