Why a Battery Monitoring System (BMS)?

  • IEEE –ANSI 1188 recommends battery

monitoring

  • 80% of businesses require uptime of

99,99%

  • Downtime cost is high (datacenter

average is 230.000€/hour)

  • Increase the life and performance of

Batteries

  • Reduces operating cost
  • Monitoring = Sustainable

What do we have to monitor?

  • Current and Voltage
  • Temperature
  • Internal resistance
  • Visual : Condition of the battery (no

corrosion, leakage of electrolyte,…)

A Lead Acid (VRLA) Battery Model

  • There is no standardized battery model…

BMS Operating Principles

  • Current, voltage, temperature and

internal impedance measurement should be performed for each battery, allowing comparing each battery against the others

  • Discharge cycles are counted
  • Operating time is monitored
  • Historical data allows battery failure

prediction

  • Comparative data between batteries of

same system allow battery failure prediction

Wired BMS

Permanent wiring between battery measurement modules (BMM) and BMS main unit Advantages

  • communication is immune to the

disturbances

  • BMMs could be powered externally

Drawbacks

  • important installation costs
  • limited number of batteries /system
  • possible failure of communication in case of

cable interruption (single point of failure on each communication cable)

  • some are performing only multiple blocks

measurement

Wireless BMS

No wiring between battery measurement modules (BMM) and BMS main unit. Communication is performed in RF Advantages

  • Very easy and cost effective installation
  • High number of batteries/ system possible
  • Overall cost is lower than wired BMS
  • No need of external power supply for the BMM
  • Measurement modules are better isolated

Drawbacks

  • Communication can be affected by heavy shielded

environments
