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.

YourDC CEO Scott Hicks

Redflow cuts $1700 in power costs at holiday house

Australian technology entrepreneur Scott Hicks has saved thousands of dollars a year in power costs at his riverside holiday house by adding solar panels and a Redflow ZCell zinc-bromine flow battery.

Mr Hicks, CEO of private data centre provider YourDC, bought the spacious house at Mannum, a Murray River town 84 kilometres east of Adelaide, as an accessible hideaway from the working week. The 10-year-old holiday house is on the banks of the Murray River, among gum trees and wildlife.

However, during his first year, Mr Hicks discovered this peaceful repose came a price – the high cost of electricity. “During the first year, we found that our power bills were huge,” he said. “Our usage peaked at the most expensive time of day because we had lots of air con running.”

After researching solar panels and energy storage systems, Mr Hicks said Redflow’s ZCell zinc-bromine flow battery stood out. “I decided that Redflow was the far superior option out at Mannum where it’s a couple of degrees warmer than in the Adelaide metro area,” he said.

Qld family goes off grid with solar and 60kWh Redflow ZCell battery bank

A Queensland family has installed the largest residential Reflow ZCell battery system in Australia, at 60kWh, as part of an off-grid solar and storage system will allow them to avoid the cost of connecting to the network, and of hefty future power bills.  The storage system, installed by Off-Grid Energy, comprises six of the Brisbane battery maker’s 10kWh zinc-bromine flow batteries (pictured below), and a nearly 19kW (72 panel) solar PV array, that is installed on the roof of a nearby shed.

ZCell – residential


ZCell is the unique zinc-bromine flow battery designed for your home or office.

Australian-designed. Battery redefined

The Australian-designed ZCell is an energy storage system built around Redflow’s unique zinc-bromine flow battery, which redefines your understanding of how a battery works.

Use 100% daily. In a fraction of the space

ZCell is a scalable 10 kilowatt-hour (kWh) zinc-bromine flow battery that can deliver 100 per cent depth of discharge each day for its warranted 10 years. ZCell comes in an attractive, outdoor enclosure.

Use your solar. Lower your bills

A ZCell-based energy storage system cuts your power costs by letting you use your solar energy when you need it, rather than selling excess solar power to the grid cheap and buying it back high.

Energy independence. Go off grid

ZCell provides the perfect energy storage solution for remote properties. Rather than pay a high price to join the power grid, buy a robust ZCell-based energy system integrated with solar panels for a fraction of that cost. Use your own stored solar-generated energy and pay no power bills – ever!

Power on. Through blackouts

ZCell gives you energy independence and keeps your lights on during grid blackouts. A ZCell energy storage system can keep your business running when your competitors are paralysed by power cuts.

10 kWh capacity. From Day One to Year 10

ZCell delivers 10 kWh of sustained energy storage every day, fully backed by Redflow’s 10-year warranty. ZCell’s zinc-bromine flow battery means no loss of storage capacity – for a decade!

Environmentally friendly. Fully recyclable

The ZCell zinc-bromine flow battery is made from easily recycled or reused components. At its end of life, the battery’s zinc bromide electrolyte solution can be purified and used for new batteries. ZCell also helps to reduce carbon emissions. “With Redflow ZCell batteries and Tindo Solar panels, we can seriously reduce our carbon emissions,” said Craig Wilkins, CEO of Conservation SA.

Safe energy storage. For your home or office

Redflow’s zinc-bromine flow batteries are intrinsically safe devices. These temperature-tolerant zinc-bromine flow batteries contain an inherently non-flammable electrolyte solution, with a design that means there’s no chance of ‘thermal runaway’ – unlike legacy batteries. “ZCell can cope with a high heat environment, which is not true of a lot of batteries,” said Google Engineering Director ANZ Alan Noble, an early ZCell customer.

Redflow. Redefines the battery

Redflow’s ZCell zinc-bromine flow battery redefines your understanding of how a battery works. With 100 per cent depth of discharge daily, the ZCell delivers a sustained 10kWh of energy storage capacity throughout its operating life.
