BMS – Battery Management System



Redflow's Battery Management System (BMS) creates 'smart batteries'

The key to Redflow’s “smart batteries” is the Redflow Battery Management System (BMS) which:

  • Simplifies Redflow battery deployment and configuration
  • Remotely monitors and manages Redflow batteries
  • Ensures Redflow batteries always contain the latest software updates.

Control via a web browser

The BMS is a small DIN Rail-mounted device that connects one or more Redflow batteries with the inverter-charger that your installer provides for your energy storage system. The BMS lets you set up, monitor, and control your Redflow battery using a web browser. It also provides battery status and operational information to your AC inverter-charger so that it can optimise its use of the electrical energy stored in your battery.

Embedded know-how

The Redflow BMS is a device that embeds more than a decade of know-how in the efficient and effective real-world operation of Redflow’s unique zinc-bromine flow battery. The BMS enables rapid on-site commissioning using just a smartphone or laptop. The BMS also provides secure remote access via any Internet path, using its built-in Ethernet or WiFi ports, to the Redflow battery management cloud service.

Cloud-enabled remote monitoring and management

The Redflow BMS leverages modern cloud infrastructure to enable easy and effective remote access to installations of Redflow’s zinc-bromine flow batteries. The BMS supports remote system performance monitoring, alarm monitoring, diagnostics, performance optimisation and software updates. The BMS also gives integrators a “fleet-wide” view of their customer sites and enables Redflow to cooperatively optimise sites with integrators.

Real-time display and system control

The Redflow BMS ‘knows’ how to efficiently run ZBM2 and ZCell batteries including:

  • Seamlessly managing battery maintenance cycles
  • Optimising energy efficiency by sequencing batteries in charge and discharge to suit the application requirements
  • Real-time status display and system control
  • Continuous logging performance data to the secure Redflow cloud, and
  • Remote battery fault detection and management.

Industry standard

The Redflow BMS uses industry-standard protocols to interface ZCell or ZBM2 clusters to energy storage systems. The primary protocols supported for energy system interfaces are CANBus BMS protocols, MODBUS-TCP, and URL-based data retrieval using JSON or plain text.

Interfaces

  • Isolated Power Supply input (9-65V DC)
  • Ethernet and WiFi Internet access ports
  • Opto-Isolated CANBus port for energy system interfacing
  • RS485 MODBUS port for ZCell/ZBM2 connection
  • Dry-contact relay for external device control using built-in event-based rules engine
  • Also supports external device control via MODBUS-TCP write commands and using USB-attached relays, and
  • USB ports for future expansion.

South African factory beats power cuts with Redflow batteries

South Africa’s largest manufacturer of printed circuits has beaten frequent power outages and cut its energy costs by deploying Australian-designed Redflow zinc-bromine flow batteries.

Unreliable mains power supplies meant Johannesburg-based Bosco Printed Circuits often had its production line stopped in mid-shift by power cuts, which could occur as often as twice a week. These stoppages each cost as much as 10,000 rand (A$1000) in wasted materials as well as disrupting Bosco’s tight delivery schedule to its many customers in the mining, security and industrial electronics sectors.

Bosco solved these power cut problems by installing 14 ZBM2 zinc-bromine flow batteries, from Brisbane-based Redflow Limited, which now keep its production line running through power cuts. Continue reading “South African factory beats power cuts with Redflow batteries”

Redflow delivers sustained energy storage to keep your business running

Redflow delivers a range of energy storage solutions that keep your critical production lines running through power blackouts and enable you to avoid punitive charges from peak demand tariffs.

Redflow’s unique zinc-bromine flow batteries are designed to power critical sites in the toughest conditions, including temperatures as warm as 50 degrees C (122 degrees F) with no external cooling. This makes Redflow’s 10 kilowatt-hour (kWh) ZBM2 batteries the ideal solution to business problems such as poor quality or unreliable power supplies, intermittent renewable energy sources and high demand tariffs.

Power outages can hit businesses hard, imposing financial punishment from interrupted production, delayed deliveries and damage to production lines and products. Unexpected power dropouts can last from minutes or hours to days or weeks in some locations.

Redflow battery-based energy storage systems can deliver emergency backup power for sites ranging from shopping centres, data centres and factories to telecommunication towers, rural pumping stations and mines. Delivering 100 per cent of their stored power, Redflow batteries offer a robust backup solution for grid failure.  A ZBM2 battery can be put into Standby Power Supply Mode, in which it is stored at any state of charge and powered up within seconds. Please contact Redflow for further details on this option.

Integrating seamlessly with renewable power supplies such as solar and wind, Redflow ZBM2 batteries can help reduce business energy costs by replacing or supplementing grid power and avoiding Demand Tariffs. Redflow batteries can also reduce energy costs by storing off-peak electricity and supplying it to the business during peak demand pricing periods.

In Johannesburg, South Africa, Bosco Printed Circuits uses 14 Redflow ZBM2 batteries integrated with 51 kilowatt peak (kWp) of photovoltaic solar panels to power its production line through load-shedding blackouts and to assist with peak shaving. The company stores off-peak power overnight for use during peak demand periods each morning and evening when energy costs can surge 300-400 per cent.

Redflow’s modular design enables you to scale an energy storage solution to suit any size of business. You can have from just one ZBM2 to dozens of batteries. This is demonstrated by Redflow’s Large Scale Battery (LSB) reference platform, built in a 20-foot container form factor, which works as a “virtual battery” holding as much as 600 kWh of energy. Adelaide business centre Base64 has installed a Redflow LSB, integrated with its large solar PV system, to guarantee at least four days of continuous energy supply.

The benefits of Redflow zinc-bromine flow batteries follow:

  • ZBM2 stores solar energy until it’s needed, eliminating the intermittency of renewable power
  • ZBM2s store from 10-600 kWh of energy with no storage capacity loss over 10 years
  • ZBM2 can deliver 100 per cent depth of discharge on a daily basis
  • ZBM2 ‘virtual genset’ mode loses no power over time and starts in 30 seconds
  • ZBM2 works in temperatures as warm as 50 degrees C (122 degrees F) without active cooling
  • ZBM2 contains inherently non-flammable electrolyte with low risk of thermal runaway
  • ZBM2 allows remote access or monitoring via the Internet to reduce the need for site visits
  • ZBM2 size and unique design reduces the risk of theft
  • ZBM2 can be stored at any state of charge – from empty to full – for months or years. Please contact Redflow for further details on this option.

Dutch farm deploys six Redflow batteries

In a Netherlands first, a Dutch dairy farm has deployed six Redflow ZBM2 zinc-bromine flow batteries to store self-produced solar energy that can support its milk production with sun-harvested energy. Dubbed the Photon Farmer, the project aims to store solar energy for the farm’s use with six 10 kilowatt hour (kWh) ZBM2 batteries, the first Redflow deployment in the Netherlands.

Located at Vierakker in the eastern Netherlands, the 57.5-hectare family-owned farm currently stocks 110 dairy cows. Due to public importance, the European Union is co-financing the deployment, which could revolutionise energy supply by supporting businesses to become energy independent. ICL, a leading global producer of bromine and supplier of the advanced zinc-bromide electrolyte used in ZBM2 batteries, proposed Redflow for the Photon Farmer project because of the ground-breaking advantages of zinc-bromine flow batteries over older battery types such as lithium and lead-acid.

Redflow Global Sales Director Andrew Kempster, who is visiting the Netherlands this week for the project’s launch, said the Photon Farmer had produced energy with solar panels for several years. “The battery project is seeking the best business model for future local sustainable energy production, including energy storage in a battery,” he said. “Our zinc-bromine flow battery technology is well-suited for this project.”
