YOUR PARTNER IN ACHIEVING
BATTERY MANAGEMENT EXCELLENCE.

Home > Battery Management

If your mission-critical services rely on a continuous power supply system with standby batteries, you need continuous battery monitoring.

OUR MISSION: Battery Management Excellence

Organisations aiming for the highest uptime standards, where downtime is measured in seconds, know that small differences in the design of a battery monitoring and management system, particularly how it collects and manages data can make all the difference. No matter where your organisation is on its uptime journey (Tier 1, 2, 3 or 4), improving battery management will be key to improving your uptime results and standards.

That’s why leading critical power facilities and organisations rely on PowerShield.

Battery failure is the single biggest cause of UPS failure and downtime. Continuous battery monitoring is crucial because UPS batteries play a critical role when the mains power fails, and one failing battery can affect the performance of a whole string. Every battery must perform to keep critical services running. The more your team knows about your batteries, the better their chances of preventing downtime.

Continuous battery monitoring is a proactive solution that provides real-time battery data, analytical tools and controls to better manage batteries. It can often detect failing batteries months before they become an operational risk, facilitating timely, proactive battery replacement, and saving time and money.

Continuous monitoring for peace of mind

  • More reliable performance-ready batteries
  • Reduced costs and extended battery life
  • Proactive maintenance and replacement
  • Improved battery warranty and regulatory compliance
  • Fewer, safer manual battery interventions

What we measure

To effectively manage standby batteries well a battery monitoring system must collect the right data at the right sensitivity and frequency to enable effective management. The best Battery Monitoring and management systems like PowerShield8 provide permanent and continuous monitoring at a block, string and environment level. Individual battery and string parameters are measured against user-defined limits specific to each battery state (float, idle, charge and discharge) supporting both float and intermittent charging regimes.

Battery Level
Voltage
Correct float voltage is critical for battery life. Incorrect charge voltage may result in loss of battery capacity, accelerated grid corrosion, excessive gassing and premature end of life. Voltage also helps identify catastrophic battery failure, such as short circuit cells, and gives visibility of battery performance under discharge.
Impedance (Ohmic Value)
Battery impedance increases with age. High resistance results in a battery that cannot supply the current required when needed. By trending impedance the batteries expected end of life can be accurately predicted. High impedance readings can also highlight poor connections and open circuit batteries before failure.
Temperature
Measuring the temperature of each battery allows the early detection of thermal runaway. It pinpoints localised environmental and HVAC problems and can also highlight poor connections under discharge and excessive charger ripple current.
Ripple Voltage
Measures the ripple affect from the AC system impacting each battery. Excessive ripple voltage can affect battery life.
String Level
Voltage
Calculated from the individual battery voltages.
Current (Amps)
String current is the energy delivered or accepted by each string of batteries. A UPS system only measures total current and cannot detect imbalances between strings. An imbalance highlights problems within a string. String current measurement also allows detection of incorrect charging and significant earth leakage faults.
Ripple Current
Detect excessive ripple current and unexpected changes over time that can cause battery damage.
System Level
Ambient Temperature
A battery’s life-span is normally specified at 20-25 degrees Celsius. Temperatures outside the specified range can significantly affect a battery's corrosion and shorten its life. An 8-10% increase can decrease a battery's life by 50%.
Ambient Humidity
Ambient humidity helps detect HVAC issues.
