Special features of CBC Battery monitoring system

• Track critical variables like temperature, internal resistance, state of charge, state of health and voltage levels to extend battery life.
  
  
• Regular evaluation and prompt action can save time and costs and improve reliability. The Battery Monitoring System must track parameters and perform voltage cell auto balancing.

1.Why Battery Monitoring System matters?

• For uninterrupted operation and businesscontinuity, a reliable power backup system iscrucial.
• During grid failure, batteries provide DC orconverted AC backup power to safeguard sensitiveloads, regulate voltage and prevent any powerinterruption.
• This ensures seamless operation of businesses24/7 and is essential for any business that valuescontinuity and reliability.

2.HOW?

• Ensure that the battery monitoring system is equipped with real-time monitoring capabilities for critical battery parameters and the ability to balance cell voltages.
  
• This will help guarantee that the battery system possesses sufficient power capacity to sustain your critical loads.
• It is essential to emphasize the need for the battery monitoring system to have a cell voltage balancing function.

3. Benefits?

• To prevent losses and downtime due to grid failures, businesses must establish contingencyplans.
  
• This can boost profits and growth by avoiding unnecessary costs and disruptions.
  
• A thorough strategy should anticipate risks and offer preventative solutions.
  
• Prioritizing prevention allows for efficient and productive operations, ensuring business success.
• Elevate your team's proficiency in data analysis to a professional standard.

7. WHY VOLTAGE CELL BALANCING

MATTERS?

Voltage cell balancing in lead-acid batteries can help improve the overall performance and extend the battery life to some extent. Lead-acid batteries are commonly used in various applications, including automotive, backup power systems, and renewable energy storage. These batteries consist of multiple cells, and voltage cell balancing aims to ensure that each cell operates at a similar voltage level.Heres how voltage cell balancing can contribute to prolonging the life of lead-acid batteries:

7.1 PREVENT OVER-UNDER CHARGING

Voltage cell balancing can help prevent individual cells from being overcharged or over-discharged. Overcharging can lead to the generation of excessive heat and the production of harmful gases, which can damage the battery. Over-discharging can cause irreversible damage to the cells.

7.2 MINIMIZING SULFATION

One of the common causes of lead-acid battery failure is sulfation, which occurs when lead sulfate crystals form on the battery plates. Balancing cell voltages can help prevent or reduce the formation of sulfation, preserving the battery's capacity and performance.

7.3 REDUCING STRESS ON INDIVIDUAL CELLS

When voltage cell balancing is in place, it ensures that no single cell is subject to significantly higher stress than others. This leads to a more uniform wear and tear on all cells, which can extend the battery's overall life.

7.4 ENHANCING CHARGE EFFICIENCY

Balanced cells can charge and discharge more efficiently. When cells are at similar voltage levels, energy transfer within the battery is more efficient, resulting in less
energy loss as heat and longer cycle life.

7.5 IMPROVED CAPACITY AND CONSISTENCY

Voltage cell balancing helps maintain consistent capacity and performance across all cells, ensuring that thebattery can deliver its rated capacity over its service life.
