Ni-Cd battery XHP series

Product catalog summary

Overview
The EverExceed XHP series of NiCd sintered plate batteries are engineered for critical applications such as UPS systems, engine starting, and emergency backup, offering a service life exceeding 20 years due to their robust construction and sintered technology.

Construction and Durability
Featuring a steel superstructure and polypropylene casing, the XHP series is corrosion-resistant and outperforms lead-acid batteries. They are designed to endure electrical abuses and function in extreme temperatures from -50°C to +70°C.

Applications
These batteries are ideal for high power applications including locomotive diesel engine starting, UPS, rolling stock, and automatic guided vehicles, as well as in hospitals, traffic control, power generation, and offshore installations.

Performance and Specifications
The XHP series exhibits high tolerance to overcharge and over-discharge, with a wide operating temperature range. They deliver high cranking currents and have a substantial electrolyte reserve for extended maintenance intervals, conforming to IEC60623 standards.

Charging Recommendations
A constant voltage charging method with current limitations is recommended. Initial charging should follow constant current as per IEC 60623 standards.

Battery Models and Specifications
Specifications for models ranging from XHP5 to XHP300 are detailed, including nominal voltage, capacity, dimensions, weight, terminal type, and container material, with capacities from 5Ah to 300Ah.

Discharge Data
Discharge tables for stationary applications provide available amperes at various discharge times and temperatures.

Discharge Performance
Discharge tables are categorized for stationary applications, engine starting applications, and performance after prolonged float charge, detailing available amperes at +20°C ±5°C for different discharge times.

Calculation Methods
The document outlines methods for calculating battery capacity, including nominal voltage, load current, backup time, and temperature range, with a formula for determining the number of cells required based on system voltage and cell float voltage.

Example Calculation
An example calculation for maintaining an inverter load of 50KVA at 0.8 power factor for 30 minutes results in selecting 184 cells of XHP300 type.

Float Voltage Operation
The document emphasizes selecting the correct float voltage (typically 1.40-1.45 V per cell) to maintain battery condition and provides a method for calculating the number of cells based on system voltage.

Conclusion
This document serves as a comprehensive guide for selecting and calculating the appropriate NiCd battery configuration for specific applications, ensuring optimal performance and reliability.
