What is flow battery technology?

Flow battery technologies may be applied to provide modular, configurable, and scalable energy storage. Flow battery energy storage systems (ESSs) can support renewable energy generation and increase energy efficiency. Applications may include providing power to remote, off-grid locations (e.g., military sites or remote communities).

What information can a PCs receive from a battery management system?

The PCS should be able to receive analog quantities such as LFP battery voltage, temperature, calculated power, and switch information such as battery normal operation and fault alarms sent from the battery management system.

Do flow batteries contain a zinc-bromine complex?

The flow batteries in the system contain a zinc-bromine complex that, depending on state of charge, presents varying chemical safety concerns. Under normal operating conditions, the liquid is contained within the flow battery tank.

How do I provide control and auxiliary power to the PCs?

To provide control and auxiliary power to the PCS, an auxiliary power circuit is provided, which includes a MV fused disconnect switch, auxiliary power transformer, low voltage power distribution, an uninterruptible power supply (UPS) and a power source for external battery heaters, if required.

What type of batteries are used in stationary storage applications?

OSM focus entirely on lithium-ion (LFP) based batteries, which are the most widely deployed type of batteries used in stationary storage applications today.

Why do flow batteries have shunt currents?

Flow batteries suffer a unique loss mechanism known as “shunt currents.” Shunt currents occur because the manifolds feeding the conductive electrolyte provide a form of short circuit discharge path for the ZBM. Shunt currents are non-linear; they remove more zinc plate from the center cells than the outer cells.
